Working on an F650GS. I may have to kill someone
« on: August 14, 2009, 12:46:45 AM »
It was time to check the valves on the baby GS's as mine is starting to sound "funny".  What crack smoking fool designed this? Me thinks that Gunther had too much Schnapps.  Faux tank tupperware comes off, drain the coolant,  remove the airboxes and the battery and move the oil reservoir out of the way.  Use your quad jointed extra long E.T. style fingers to remove the plug leads and then, after taking off the throttle cable and the multitude of bolts, you can scrape up your fingers trying to get the cover off the top of the engine.  Don't forget to remove the little bolt at the bottom of the crankcase so you can see the TDC mark, after you make sure the cam lobes are pointed in the right direction and the marks on the gears are pointing at each other.

Oh, and did I mention?  This whole nightmare is shim under bucket.  
I may not survive pulling the cams off when the time comes.....

So, put it all back together and just TRY to get the called for 1.3L of coolant back in the radiator.  I dare you.  

Now I need to to bleed the brakes.  Except that to do it properly you need the little computer that tells the ABS to open wide and release its bit of fluid.  OR, you can do a normal bleed, then take it out and purposely activate the ABS, thus release its fluid and sucking clean stuff, and then, go back and re-bleed. Since we have three 'new' BMW's we sprung for the GS911 fault code reader that will tell the ABS to do its thing.
Why, Oh Why, BMW, did you stray from the good and mighty airhead design? Why would you make working on a bike an exercise in evaporated patience, foul language and spilled coolant?  What on Earth were you thinking...putting an AUSTRIAN engine into this plastic encased contraption?  Working the airheads is so pleasant and relaxing.  Its supposed to be a bonding experience between woman and machine, not a frustrating 4 days filled with more colorful words than any sailor ever uttered. [smiley=wall.gif]   I'm done now, thanx for listening.

I understand, just let it out!!!  Every time I work on anything else it makes me appreciate the simplicity and maintainability of an Airhead just that much more.  [smiley=bmw_smiley.gif]

Airheads forever!  Anything water cooled is definitely going to be more trouble than it's worth.  There are still enough R100GS's around to satisfy the occasional yearning to get dusty.  Trade that tupperware coated goat in for something that gives you the satisfaction that you so richly deserve.

Unfortunately it can be worse - the latest AUSTRIAN engine is being produced in CHINA!
I know - built to BMW specifications and inspected. When it comes to dollars (or Euros) there are always corners to be cut so I have my doubts.
what with CANBUS technology and computerized fuel injection the days of being able to do all your own work are raapidly coming to an end. I wonder what local shop will be willing to work on these machines when they reach the age of our beloved airheads? (will they actually last that long?)

May want to forego cursing the BMW engineers. Isn't the F650 engine a Rotax? IIRC.     Monte

I believe it is a Rotax, however you have to know that there was definitely a committee locked up in a tiny room somewhere in Austria, perhaps Berchtiesgarden?, that had fiendish plans to cause grief, agony, and consternation to one of our own with the design.

I rather doubt that those bikes will be around like the airheads are.  How many Japanese bikes from the last 40 years still haunt the streets?  Most of them have found their way to the scrap heap.  You do still see lots of BMW's, Moto Guzzi's, and H-D's around.  Why?  Because the serious afficianado who appreciates the character of these bikes and enjoys working on them like DeeG keep them alive.

I love our vintage BMW Airheads. So here's a slight tangential comment for this thread but, maybe not...

The G-series "BMW" is an Aprilia-designed, BMW badged and co-produced motorcycle. An expensive attempt to penetrate the economical lightweight off-road motorcycle market, the entire program was moved to China. It was either move to a country with far lower labor rates or shut down the line. The high purchase price of the Euro-produced models made the bikes non-competitive against many other manufacturers offerings.

Kymco now builds the engines G-series! Yes, they of the zillion small scooters on every road worldwide.

Like it or not, the new world order global economy drives most every business decision. Ugh, IMHO.

So, the new BMW R1000SS is an affordable (13-14K USD) SuperBike that, in many respects, mimics the successful engineering design paradigm of the UJM. In my quirky little mind, it's still a BMW.

Let's hope BMW can sell lots of these new look and design motorcycles. Hopefully, that will permit BMW to continue at least a trickle of OEM parts for our beloved Airheads.

Yes, I know the Chain Gang site well.  Inmate #2517 here!  The FAQ's and the maintenance DVD's were what kept me from pushing this thing in the path of a freight train.  

However:

The whole process went much smoother and faster on the spouses GS.  LOL.  Spent an entire day this weekend re-bonding with the machines. They sparkle and shine like the day they were rolled off the showroom floor.  I feel much better about the world now.  I guess its time to go get them dirty again.  :)

DeeG, you have brought up the very point that makes me hesitate to return to the twin F650GS, the single too and also, rethink the Triumph Bonneville twin with it's shim and bucket valves. The Moto Guzzi V7 classic gets numerous points!! Thanks DeeG!!!! Whew!
I really found the single F650GS frustrating too. The new Twin at least had an easy oil change. No need to even get it up on the centrestand. Sidestand is good! One point for an easy oil filter canister too.

Sue, I don't own any stock in M-G but had a chance to sit on the new V7 classic last weekend.  A very nice bike indeed!  I really can't be sure but the pearl white tank would probably look good alongside LRB.  I'm sure that you could run across the northern prairies all day on that scooter.  Ever think about taking Canada Highway 1 to next years rally in Redmond?

Well Bengt, it was the Trans Canada hwy. that I was aiming for last summer when all hell broke loose in Saskatchewan. I was on a more northern east-west highway in the province and was just coming south to pick up the Trans Canada. So I'll stick with the USA route which has only good memories!

There there, Deeg !  

We feel your pain - BMW Motorrad Division I think is in a technology war with the car division to see who can make the most complicated, obfuscated mode of transportation on the planet - at least that is their intention to keep their dealers & mechanics in business and well paid.
After going through so much just to get to the spark plug wires - many (but not all) would gladly fork over a Ben Franklin note to the white coated technicians to do it for them.  That, and the fact that they're going more Tupperware crazy every year (except for the R1200R) is indeed what is keeping many of us from buying new BMWs, and enjoying turning a wrench on the old airheads.

On a related note - I see that the MotoGuzzi guys are releasing a V7 Cafe' version of the V7 Classic - though the Cafe will be less versatile from a cargo perspective - it definitely has a nice look.

My next bike will be either another airhead, a Guzzi, or possibly a naked oilhead from the 90's or early 2000s.   IF I cannot adjust the valves and adjust the synch on the carbs/throttle bodies, I don't want it!! :D

The V7 is a WONDERFUL bike.  Same engine/drivetrain as my Breva, but the danged thing runs sooo much smoother.  Shifts better too.  :-?

Spouse road it to the MG National in CO back at the end of June.  Central WA to Central CO, left around 0400 on a Thursday morning and got there early afternoon on Friday.  Said he didn't feel road fatigued or sore at all.
