My T100 is due for a valve check, and based on the last time I looked, I'm going to be pulling cams and changing out some shims.

Now, at the same time, my old BMW GS driveshaft u-joints have decided it's their time to blow out! (yes, shaft drive bikes have their own set of problems).

So, I think Bonnie is going to be my primary two wheel ride for the next few weeks, while I contact the company in Canada who rebuilds old driveshafts, since new ones cost approx as much as three sets of chains and sprockets for the Bonneville...do the math, it's scary.

Well, time to dig into the old Haynes BMW Manual, and get up to speed on pulling the final drive, swingarm, and driveshaft.

When things like this happen, chain drive doesn't look so bad! Matter of fact, it looks pretty d*** good.

The last internal engine work I did was a Vance and Hines welded clutch basket on my old GS1100. Since I have no mechanical abilities left,any "inside jobs" on the Bonnie will be done by the pro`s. I`m at 16,500+miles and my valves/shims are still factory sealed.They don`t make any more noise than when new,and the bike runs stronger and smoother every day.I`ll probably have them checked this off season though.I am gonna tighten up the steering head bearings a bit,pretty soon though,just because. They are still factory tight too. :-D

Rodburner - I'm not in love with the thought of tearing into the GS driveline.

But I'm retired, and have the time to spend working on the bike myself, and of course, there's always the money thing. The driveshaft for the GS, if purchased new, is over $600.00. A local BMW mechanic who is an expert estimated it would take him 3-4 hours assuming he was doing a nice job of cleaning up all parts before replacing them. (not sure what the book calls for). That has the job up to over $900, easily.

I'm hoping the cost of having the old shaft rebuilt by Bruno's in Canada will drop the cost of the shaft in half. That, plus my labor at minimum wage, should keep the old gal on the road at a reasonable cost.

Re the Triumph valves, I trust myself to do the job right. I've read it over in the Manual so many times (as well as several posts) that I feel like I've already done the job.

Rodburner, I have similar mileage to you and was thinking of doing the valves off season as well. I find it hard to take apart something that is running perfect.

Checking the valves doesn't take much time--engine should be cold though, so you need to let it sit overnight. I would recommend checking them yourself prior to taking them to be done by a "professional", and again after getting the bike back. I would record both the before and after measurements, because the after measurements will likely change on the valves that were within specs prior to the shimming--they swap shims back and forth to minimise the number of new shims needed. :-D

Larry,I wouldn`t know what I was looking at. "Gap" is the open area between the buttons of a womans blouse,right?
Tolerance is something I have very little of and rechecking is what I do when someone steals my mail. Maybe the shop will let me watch the procedings in the fall. There`s just to many "what damage will this washer/shim/nut etc do to my bike,now that I dropped it down the hole" threads for a going blind guy like me to chance it. :-D
