your enhancing the point, your a long time grease monkey, with the situation under control.

im a professional elec and sw eng, i like to get crazy once in a while flash a prototype board and then run around the office holding it without an anti static bag... real wild like...
so i suppose we all do things we are familiar with that we wouldn't otherwise recommend to anyone else.
Might that be a good enough reason to not recommend something to a newbie that is generally frowned upon, such as using car oil with a wet clutch.

Im sure the master mechanic or his padawans wont fear any sort unwelcome side effects caused by whatever on thy bike, but others may, so why push it.
its the rest of us for whom just do not know any better...

DanDaMan,
I'm trying to get back in sync with the DF world and luckily found your post #3396 which has good links and info on common mods and problems.
Be nice if it was a sticky and more additions were made to it.
Thanks

Need to lift that DF for maintainance ? Just don't put this under the exhaust pipe.

i apologize. all the questions about numbers could be that none of them match very often.10w40 3 times in the book. 15w40 on the frame. spark=5-7 on frame, 6-8 AND 6-7 in book. valves, i've seen references from an engine with two cylinders all the way to a vw bug.
everyone uses their OWN best judgement. good luck.

Just want to say welcome back to Barnone. I want to also thank him for starting this thread, I bought my bike way back when just on all the info he started this thread on. I am 9670 miles into her life, and she still loves the road. Thanks man, would probably not have bought it without your input.
