I read something on Brook Reams rebuild site where he said on the '75 /6 models, a threaded sleeve with an Allen head inside the hole of the sleeve is used to seal the reservoir to the body. The head of the Allen bolt is pretty wide so should pull the plastic reservoir down tight to the body.

As they say, go back to the last thing you touched!! Have you had an opportunity to ask the repair shop about the problem? Maybe they might have some suggestions. But if the problem is not something inside the box, it could be that the input splines on the transmission need lubing. If the shop did t...

Interesting to see the Schorsch Meier tag on the front fender. It does appear to be early seeing the flat blade hand levers...later in the run, they had a ball on the end of the lever along with finger cutouts. The intake tubes don't appear to be the standard R69S style...might be the wrong carbs. I...

No, I didn't say that. I was basing it on the fact that the other carb did not have the hole. Maybe someone with a similar model carb can check theirs.

Darryl Richman has mentioned a compound called Muggy Weld to seal up large holes. I suspect with something like JBWeld, a small drop on the hole should seal it up well.

I read what Vech has said in the past...even Duane Ausherman. Both basically say to do it slowly and only as much as needed. If working with original parts, the wrinkling will go away once the part is returned to normal shape. Vech says he uses some nuts on threaded stems to open/close the riser.

Look at page 36...maybe that was what he was referring to.

Thanks, James. No I have not touched the carbs in a long time. I did wonder about running lean, but I've had the plugs out several times in the past few months and nothing jumped out at me as being unusual. Certainly worth a look, though. I get between 45 and 50 mpg and have been getting that for ma...

I've checked valve clearances several times in the past couple of months. I also run the highest test octane I can get. So I'm scratching my head. Thanks for the ideas!

Well, a bit of a follow up. I was able to get out on the bike. I was going through my start routine and did not have the key pushed home. I was priming the engine when the bike rumbled to life. I pushed the key down and began coaxing the throttle. So, it started rather easy. I'm going to have to fol...
