Title: 1971 A65T Thunderbolt - The other 650!
Post by: Semper Gumby on February 04, 2007, 01:30:15 PM
Hi Guys and Gals,   :D

I bought a 1971 BSA A65T Thunderbolt with matching numbers yesterday.  It wasn't running properly.  After adding one automotive plug wire, it is singing an amazing song.  One of the baffles is missing and its a bit loud.

My question: The shifter lever spring is fine but the tranny hangs between 3rd and 2nd when down shifting.  I have a hole 'nother tranny so I have some parts to work with.  My question is which ones?

BTW - It's black but originally green and white.  I have the original tank and side covers still painted green and white.  My understanding is that the frame was dove grey but the only place that appears is under the black paint on the shocks.  Everything works but the turnsignals.

Thanks,

This sounds like a fun project - a number of years ago, I was looking for a 'project' bike, and
almost bought a somewhat running BSA Lightning for the project.   I then was distracted by
Nortons (and like many men, I still am, even without the Norton Girl adverts), before I finally
decided, that if I worked on a bike, I'd want to be able to ride it on trips over at least several
hundred miles, and went back to the Marque which I knew best, and which wouldn't let me
down (at least as frequently) and finally bought my R65LS (Rosie).

Pictures when you can post them, please !!

Cool!  Is that a single carb model?  I'm not very familiar with BSAs, tho a nearby friend of mine has a '70 Lightening, dual carb.  I want to race him on my '70 Bonneville some time.  It helps my confidence that he weighs at least 40 pounds more than me....

If the wire you used was resistor wire you may want to make a new pair of plug wires when you get a chance.

Good luck with it and I too am looking foreward to pictures.

Yeah, Ed, The Thunderbolt was BSA's single-carb 650 twin, about like Triumph's TR6. Both were actually a bit more rideable in about 90% of situations than the "hotter" twin-carbers, and much easier to keep in tune, but neither had the hotrod "wow factor" and didn't sell as well.

But a race between your '70 Bonneville and your buddy's '70 Lightning? Now THAT I would love to see; hell, y'all could sell tickets!! Stats-wise, the BSA's supposedly ran just a leetle quicker than the Triumphs, although most of that was probably the rider and most likely would still be the case if the bikes were in similar condition. Unless your friend's a much better jockey, I'd say the 40 lbs. would tip it to you! [smiley=thumbsup.gif]
Good luck, and keep us posted about the race! 8-)

I don't know, I too read about the rideability factor on several Britbike forums, but how many BMW twins came with single carbs?  Any R65 owner knows how to syncronize his carbs, and both Bings and Amals basically used O-rings to keep the mixture screws from moving.

As for the race, my buddy always seems to have problems with his Lightening that he's scared to tackle.  Something about shimming the crank end play; my Bonnie is set up differently so I don't know what he's up to.  I suspect you will learn, however....   ;)

Good luck, fun stuff!

Dang Rob, that thing's prettier than my R65!  Is that some sort of sprung rear hub or just a hard tail?  Why are so many bikes (and cars and trucks!) from the 30s so good looking?  I love that decade in motor vehicles.

Thanks for the picture.

Here's one from the other end of the decade:

Gack.  The adventure continues!

I'm on the road again.  It's a single carb bike. (By definition all BSA Thunderbolts are single carb.)  And it runs (most of the time.)  

I blew a main fuse when a wire came off the running light in the speedo.  Couple of nice GA rednecks (quite drunk) pulled up and then volinteered to get me another.  Came back ten minutes later with a whole box of various fuses and got me going again with one spare in the pocket.  

The one design feature of the single carb T-bolt is that when it runs out of gas...it runs out NOW (like when you take off with the petcock closed!)

Yep the spark plug wires were carbon resistor types (woven carbon fabric - I never knew such existed!) so new solid core ones on order.

Tranny update:  It shifts OK but when down shifting I have to let the lever snap back to center in order to get it where I can select the next gear down.  Any ideas on this would be greatly appreciated.

Sorry I don't have pictures yet.  I promise next week!  

Bike has a great sound when running handles well.  Drum brakes and right foot shift take some getting use to.  Hey I don't have to balance the carb.  At the moment there is a K&N filter on it.  I have the original side covers and filter set up which I am planning to put back on.  When I put the colortune plug in to set the mixture I noticed after setting the idle mixture that the needle/main jet mixture was running rich.  I think there is not enough air coming from the K&N pod filter.  That is unless the needle main jet have not been changed!

Too cool, brings back lots of memories (and not all good)! ;)

Hey, once you get this bad boy rolling again, maybe we can settle the single vs. dual carb arguments, and you and Ed can race! His buddy with the Lightning keeps finding excuses to wuss out against his Bonneville, and curious minds need to know!

Put me down for a coupla tickets to the show, for sure!!

Lightning Vs. T-bolt - I'm told that a T-bolt is quicker off the line.  But the Two carbs bikes have a stronger top end.  I think its a bunch of hooee.  The two carb bikes, when properly tuned will beat my T-bolt every time.  My buddy's 1969 Firebird Scrambler goes like stink and really comes on the cam above 4000 RPM.  Then I start thinking about drum brakes and Dunlop K70 tires and all my speed desires disappear in the dust.

I will probably put a larger than stock counter shaft sprocket on this bike so it will turn over at a lower RPM at cruise.  Less buzzy and more pleasent to drive.  This will of course be at the expense of speed off the line!

Greetings from Cold New York's LaGuardia Airport.

Home tomorrow thank goodness.  My R65 waits patiently in the company parking lot.  I can hear it calling in the distance...

If I understand you right, then it's supposed to do that.  It ratchets back before it can get another grab on the inner gearbox shifter.  Assuming it's anything like the one on my Bonnie, that is.  The problem I had to fix was replacing the spring that returns the shifter to center (there are two, one for each direction).  To continue down shifting, I had to actually push the lever back up into the middle position with my foot.  

Avon Roadrunners will ease your high speed worries.   Your '71 brakes are widely considered to be not quite as good as the '69 and '70, but if set up right they are probably better.  In fact, I think they are similar to the BMW twin leading shoe drum brakes of the time, with something funny that I can't remember about the cables....  That was really useful, wasn't it?  

Have fun,
Ed

Hi Ed,

No the shift lever spring on the the foot change lever works fine.  But some thing inside doesn't catch the next gear unless, when I'm down shifting, I select the next gear down and then while the lever is fully down, slide my foot sideways off the lever alowing the spring to "snap" the lever back.  If I don't do it this way when I go to select the next gear down,  there will be nothing there to select.  :-?   I'm wondering where the problem is - Cam plate or ratchet or ????.  Just looking for some info before I actually dive in.  Right now I want to ride more than I want to fix it.   ::)

Post by: Ed Miller on February 12, 2007, 12:10:12 AM
OH.  Sounds sticky.  Maybe it will go away on it's own?  Some time after a ride, when the bike is well warmed up, lean it over pretty far to the right so that gear oil can flow from the inner box to the outer section where that shifter ratchet thing does it's mysterious job.  Even if that doesn't help, it's good to keep things from rusting out.  

Here's a pretty good forum for British bikes, if you haven't found it yet:

http://216.122.73.247/ubb/cgi-bin/ultimatebb.cgi

They even have a specific room for BSA stuff, though of course I haven't been into it.

...snark, snark....

If yours is anything like my Bonnie, ride it enough and you will agree with me that R65s don't vibrate.

At all.

The foot pegs buzz abit but the handle bars are OK.  My friend's Firebird buzzes a lot more.  I bet its the carb sync.  AMAL's don't have manometer sync taps.  And I thought tuning Bings was an art!!!!

The dual carb models have a cross over tube (1/4" fuel line) between the two intake manifolds, which is where you attach the manometer.  Lately I'm getting so lazy I just do it by ear, though.  Amals are much simpler than Bing CV carbs, but they don't seem to hold the tune for as long.  I don't know why.  Maybe because the points wear out a bit and people try to tune the carbs to compensate...  I hope I'm past that sort of stuff!

Why do you think the Britbikes use dual points whereas BMW apparently did just fine with one set of points and a wasted spark?  I'm guessing it's a hot rod thing, giving each coil more dwell time and a hotter spark, but I wonder how much difference it really makes.  My mom has a '65 Imperial with a 413, and I was reading her shop manual prior to tuning the car up and noticed that they had a dual point option for the muscle cars; thankfully hers just has one set of points.

Title: Re: 1971 A65T Thunderbolt - The other 650!
Post by: Justin B. on February 13, 2007, 06:24:12 PM
Dual points allow you to keep juice on the coil primary longer, resulting in better saturation (especially at higher RPM), and therefore stronger spark.  Perhaps the BMW doesn't really need this due to being a lower revving engine than some...

Mine may be one of the bikes that came over Dove grey and then left the dealer Black.  My friend said when they arrived, the faithful revolted.  Dealers had to paint the frames black in order to get them to sell.  Curiously on this bike the only place I can find the Dove Grey is under black paint on the shocks.  Perhaps this is a "black" framed model.

I was going to go and flush out the engine with fresh oil (of a brand not to be named in this forum or even under extreem duress).  But the temp is going to be 22'F tomorrow and I just don't feel like working out of doors in the cold. :(

I reserve the right to change my mind on this however....

Yep that is the Norton kit which is available from a couple of places.  What a nice T-Bolt.  That is what I am aiming for...It has the larger tank (good) and the bar end mirrors (not stock)  and aftermarket shocks.  Stuff noted!

But all in all...SWEEEEET!   :)

Bill,
As far as the shifting problem goes, there may be an upgrade you can go for. If the BSA is anything like it's brother the TR6R the indexing cam in the tranny is locating via a leaf spring that presses into the indents on that cam. The upgrade was to go to a plunger type spring by drilling and threading the bottom of the tranny. This was as seen on later models. Ask about this on the Britt lists, I'm sure someone will be familiar with it. Also, the old britt gearboxes are very much affected by weight / grade of oil so you may also want to start a dreaded "oil thread" but you'll get lots of answers!
you may also want to refer to this list: http://users.rcn.com/cstringe/brit.html

Hey Rich, it doesn't look like Chuck pays much attention to the Brit Iron list front page.  Do you think I can still get free 2004 election bumper stickers?   ;D

I've been on Brit Iron since the late 80s.  I think it predates the internet as we know it.  It's really died down over the past couple of years, fewer than 500 members now.  

I'd forgotten about the plunger spring mod; all the Triumphs had them up until 1970; in 1971 they switched to the leaf spring you mention, and I don't know when they switched back.  You could have mentioned what oil you run in your Triumph's gear box....  :-)  I use 75W-90, not AMSOIL yet but I will switch over eventually.

Ed,
Um yes the archives page is a bit dated... I haven't been signed up there for a couple of years. It was, and probably still is an interesting list even tho' the format does date back to the days of direct dial up to a server. It was my introduction to a world where Haynes wasn't the ultimate authority! I can remember heated debates on the metallurgy of "pot" metal or the virtues of plug indexing. The regular posters ranged from informative to hilarious. I was always fond of how "Pete the cheep" solved problems with common household remedys. Ah but the increased political bickering took away from my refuge which is still motorcycling. The lack of specific areas on a list like that, for off topic posting, is what (in my opinion) caused people to move to more modern formats like this one. Still a good source none the less.

Wow!  Drained the oil (from the Frame) and the sump screen yesterday.  I have never seen such goo.  Black goo about 1/2" worth around the resevoir filter!   Just a little below the sump screen.  Cleaned it all out and poured in a cheap 15W40 desiel oil to clean the bike out.  I'm going to run it about 100 miles and then dump it.  Then I will do it one more time before switching to expensive motorcycle only 20W50 or possibly a straight 50 weight.

No shiney metal bits (thankgoodness).

Tranny still doesn't down shift properly.  I'm getting ready for surgery.  Collecting gaskets and seals first.

Fresh oil, NGK Iridiums and new solid core wires - bike runs great faster than the brakes are good for.  Sorry I forgot the camera.  Still no pics.

After engine warms up, oil presssure light comes on at about 1500 rpms.  I'm hoping the thicker oil will cure this otherwise I will rebuild the oil pump.

It needs a new battery plus the original sidecovers back on (Which I have).  The black paint is actually really nice black on top of Gold flake.  When the sun hits it the gold appears.  Not a stock color though.

What a nice day for a ride.  Almost all the electrics work!  A $2.89 2 post flasher from Autozone has the turnsignals working just fine after last weeks tear-down of the Lucas handle bar switches.  The front brake cable has a short in the switch so it is disconnected (Switch that is, brakes work OK).  Everything else works.  The chain is shot so I'm replacing the sprockets and putting on a modern o-ring chain.  This bike is approaching "reliable transportation" status.

Got the new 5 gallon fuel tank in the mail.  Time to get it and the side covers painted.  (What color?)

R65 is still at Nathan's.  The wrong parts showed up (R65s are different).

Spring is sprong on the South.  Timetoridetimetoride......

Is your front brake switch that in-line one, giving you a two part front brake cable in effect?  I don't think I've ever heard anything good about them.  That's what would have been stock on my Triumph, but when I got it in '87 it had already been changed out for a 1 piece, and I recently had a new one made to fit which is also one piece.  I just turn on the brake light with the rear brake.

For a long time my R65 front brake switch didn't work either, but it started working again.  What ever.  I'll probably buy a new one some day.....

Hope you had a good ride!  I put in a couple hundred miles last Saturday on the Triumph, having fun on curvy roads with my Airhead friend Keizer Dave on his beautiful R75/5 Toaster.  Luckily SWB!

Yep a two piece!.  New one on order.  A Barnett! (I have always had good luck with Barnett stuff)

Mid seventies.  Drove down to the Autozone in Barnsville to hunt down and kill the flasher.  Then a short jawnt to the "The Rock" Georgia and a visit to the 12 "unknowns".  Beautiful day.

I hate to say this but a good friend of mine from church went to St. Joseph's hospital in Atlanta for some abdominal surgury.  After eight weeks he is still not out of the ICU.  Various hospital induced infections have kept him in.  Now the family has gone quite with e-mail updates and I fear the worst.  (What can be worse than eight weeks in the ICU???)  His name is Duncan Curl and a prayer (if you are so inclined) would be much appreciated.  Thanks in advance.

Short update.

My friend Duncan Curl is out of the ICU (phew) and (thank you).

Did major surgery on the LH side of the A65T yesterday to replace the countershaft sprocket chain and drive shaft sprocket.  This was a major deal.  Took about ten hours.  Oh and the new brake cable with the switch nobody likes - the switch didn't work!!!!  I had to dissassemble the thing and adjust the position of the contacts to get it to function! :o

To get to the countershaft sprocket you have to remove the Alternator, Primary chain, Clutch and Clutch basket with its twenty little rollers that make up the clutch basket bearing.  All back together (after three tries) and running though.  More later....

I have one small leak on the RH side of the engine left to go.

Good to hear about your friend; you're right, that was a long time in ICU.  Sheesh.  I think hospitals are dangerous places to be.

For your counter shaft sprocket, I've never had to remove the alternator.  I get the clutch basket stuff off, and wiggle until the 20 little bearings fall out into a ready pan, and the primary chain comes off.

When I'm ready to put everything back together, I install the little bearings with small needle nosed pliers.  I don't  even have a clutch hub puller.

As always, I have no idea how a BSA is assembled in that area.

Time to paint.  I have a large 4.5 gallon tank from e-bay and its time to paint it.  There is one problem.  I don't like the original color - "sterling moss green" is a bit too frog-like for me.  I'm leaning to the same lines as BSA put on their tanks but in a different color.  Right now I'm liking black with a peralecent white or metalic silver.  Here is a pic of the green and white from a bike in Holland.

Well I have stopgapped my oil pressure issues on the 1971 Thunderbolt.  The I'm running Spectro 70 Wt with some Lucas oil stabilizer and a Lockhart oil cooler.  This keeps the oil pressure light from coming on even in Stop 'n Go driving (94'f in Atlanta today).

I've got some brake parts from England to make the Drum brakes work better.  And now it is time to paint the tank and side covers and go ride the bike in the North Georgia Mountains.

The bike is FUN to ride.   :D

Sorry I'm going to miss the BMW-RA in Ashville.  You all have fun.

TTFN,

Bill

My dad had an A65 when I was a kiddy in the '60's and it was the first bike I ever had a ride on. . I've always fancied one but never had the money when the opportunity came up

Well The tank and the side covers are back.  I decided on Jaguar Racing Green (HJZ) with stock BSA decals.  Came out really well.  I decided against the two tone paint job because it hides the lines of the tank which are really nice.  When I get the bolts and bits to assemble the side covers I will pull it out in the sun a take a pic.  I can hardley wait for the parts to get here from Iowa.

TTFN,

Nice Bill, great colors. I like it!! [smiley=thumbsup.gif]

But wait a minute: earlier you had a pic of a red TT (Firebird Scrambler, I believe, what I once owned 1.7 of)) on the thread about gear ratios.

Does that mean you're peddling two Beezers now??  :o

Yes.  I got tired of watching bikes go for less than I would pay for them so I put a lark bid on a good looking Firebird one day before close and won!  I was shocked.  Turned out to be a nice bike though.  Complete minus the grab bar.  Tank in good shape.  Seems I'm heading back in time on these things.

There is a 1935 BSA Bluestar with real Lucas Aceteline Lamps (front and rear) that I'm looking at but the gent in question wants too much.  Can you imagine having to light your headlamp and tail light and then tickiling the carb to start the bike?  Can you say "Home before Dark?"  I knew you could!

It looks like a time machine to me.   ;)

Way cool bikes.  Gotta love those old BSA starburst tanks. [smiley=thumbsup.gif]  Have fun!

Just be sure to tickle and light in the exact order as listed above, though: tickling first might lead to fuel on gloves which = 3rd degree burns when you "turn on" the headlamp!  [smiley=flamethrowingsmiley.gif]
