Thanks. While we're here (since we're talking about other brands, I guess it's on-topic, more or less), can anyone who's seen "Colonel Blimp" or knows British Army equipment in general inform us what those bikes were in this sequence? (Because the film was made in 1943-44, I'd guarantee they aren't beemers.  ;D) Perhaps some of our members in UK could enlighten us regarding early WWII standard=issue motorcycles there.

The film is unbelievably rich Technicolor. The gods only know how Michael Powell was able to get his hands on so much (163 minutes in its final cut) high-quality color film stock during the war, particularly in light of the hostility of the British government toward "Blimp."
 
Of interest to riders: The script refers to a WWI sidecar bike as a "bathtub," and the scenes involving it illustrate why.  That's a  British Army slang term I hadn't encountered previously.

For those who love films in general (with or without bikes), the cinematography, including the courier bike sequence, is ingenious. The bike sequence is the very opening of the movie, just after a brief shot of a teletype message being received in code; it establishes context more concisely, without a word of dialogue or narration, than any that I can remember.

BTW, "Colonel Blimp" is a film about humanity during and between wars, not a "war movie."

I recommend it. See it if you can. JT

I have rebuilt the motor in the Thunderbolt and it is in and runs Great!  BUT....

The left hand cylinder is smoking which is really odd because I have 150 PSI compression on both the left and right cylinders.  The smoke clears up when I get out on the road and run at a constant RPM.  It really starts to smoke when I'm sitting at a stop sign/light and I blip the throttle.  So I'm burning oil like crazy.  There are two theories:

1) The LH rings have not seated.

2) The LH intake valve guide is cracked and oil is being sucked into the cylinder from the top end.

I've got 500 miles on the motor and I'm going to put another 500 on it before we open up the top end and have a look which is too bad because other than that the thing runs great/sounds great.  

Cruise Control:

I just put a NEP CC-2 throttle lock on the the Thunderbolt and it works great.  I've got a second which looks like it will install on the R65 (sorly needed).  All I've got to do is trim about 3mm of the innermost protion of the throttle grip away to give the throttle lock some space.  It looks like it will clamp around the throttle friction screw where some have installed the flip lock for cruise control.  If it works I will post pics later.

Time for another BSA UPDATE!!

The Thunderbolt is still smoking.  The head comes off in 350 miles to diagnose which is too bad because its running great.

I did something really cool yesterday.  On the Firebird the Woodruff key that holds the Lucas rotor for the Alternator on the LH side got loose due to the DPO not setting the bolt to the right torque.  These rotors are built around a steel collar and what eventually happens is that the steel on the collar seperates from the aluminum that hold the magnets (due to vibration)around the steel collar.  Left to its own I will eventually explode.  This is bad.  In the mean time it makes setting the timing really hard.  So I bought a new Wassel rotor and found the the key way on the crank was nolonger the right shape as it had also widened.  I was devasted because it looked like I needed a new crank.  Well I found out that all you need to do is get some wider key stock and file it down until it fits in the new wider slot and wala no more loose rotors.  

I did this yesterday.  Took about two hours and saved the crank.  I can't tell you how chuffed I am about this.  Was out running around on the Firebird today and it is now running great.  Cost me all of 16 dollars for the files, some key stock, some red Locktite, and a gasket.

Too cool.  I almost feel like a real mechanic.

Was your rotor bad?  Mine was.  I was afraid that knocking sound was a rod or something, so I guess I was relieved when I found the cause.

What is key stock made from?  I made an oversized one out of some scrap stainless steel I had around the shop, but I wonder if that's not really too hard.

Congratulations on that fix!  Hopefully all you need is a new hone job and you'll get that bike to stop smoking.  What grit hone did you use?

Hi Ed,

I just went to my Hardware stor to get the key stock.  Yes the rotor was bad on top of everything else.  As for the Thunderbolt.  I don't know.  The person who did that part of the rebuild used a dingleberry hone.  I don't know what the grit was.  The compression is 150 left and right so there is a good chance that the intake valve guide is cracked and is sucking oil.  I will find out after Daytona.

TTFN,

The suspense is killing me - I gotta know how this turns out !

On a somewhat related note - if any of you Triumph aficionados are interested, this rather rare Trump showed up in CL up here - it is pricey, but probably worth it?

Me too.  Daytona is going on at the moment.  My buddy Ron Mass won the AHRMA Classic 650 race on an old Norton.  (I will get pictures of the bike).  Ron is a bit of a ringer as he used to race Yamaha TZ-750's at Daytona back in the 1970's with AMA National Number 40.  (Yamaha TZ-750 = Fire Breathing Monster on wheels)

I of course had to work flying around in the last big snow storm up the east coast.  This made for long days.... :P

Took apart head off the Thunderbolt today and...The intake valve guides/valve stems are a bit worn (.003" combined) so I'm getting some new valves and guides.  Also tried a Hepolite ring instead of the ones that came with the new pistons and the end gap is a little tighter so those will go in as well.  If I dont fly tomorrow I try to get some pictures.  The carbon patterns in the piston dome are really interesting.  There are parts of the piston near the edge that are clean... which after almost 1,000 miles is surprising.

The Thunderbolt is back home with new valves and Hepolite rings.  And just today I get the latest copy of Airhead and it has a deperaging article about the valves I put in the BSA!  Arrgh.  Oh well.

The tank for the T'bolt is being resealed so I can't run it yet.  The saga continues.  Thank the Lord I have an R65 (well sorted).   ;)

What valves did you use?  I had Black Diamond valves put in my R100 when the heads were redone - no problems after 3 years. (knock-knock...)

Same ones I had put in the r100 heads and I've had no problems.  It seems that some "dyed-in-the-wool" Beemer snob "gurus" think any valve other than OEM is crap, but other "experts" seem to accept the Black Diamond valves is a viable substitute.

I have them in my Triumph.  But I doubt they'll last 60,000 miles like my original, defective BMW valves did.  It easy to find lousy aftermarket British bike parts but I've always heard good things about Kibblewhite Black Diamond valves in that crowd.  I was surprised by the article in Airmail too.

Well...I'm keeping my fingers crossed.  Anywho..The tanks is resealed and back on the bike.  I'm going to crank it tomorrow.

In the meantime I'm thinking about buying this 1964 A65 Royal Star...I must be insain.
