Have an 85 Rebel purchased 3 years ago with 3000 miles. Have over 8k now. Figured it was due for a valve adjustment - didn't know previous maintenance schedule. Used .003 inch feeler gauge. Seems to start/run OK but actually sounds louder - ticking/rattling noise on acceleration. 2x tried to adjust but same result. Haven't actually ridden due to rain but don't remember hearing the ticking noise when I turned the accelerator before the adjustment. Do I try again and go even tighter? Next one down is .0015 - should I use this one? How tight is tight... :)

Thanks.
JC

Were you sure to get the engine rotated in the right directions for each side?

Check this out: http://www.rebel250.com/rebelforum/viewtopic.php?t=3881

Very descriptive step-by-step guide, I made the mistake of getting the alignments mixed up the first time and had a similar problem.

I made that mistake the first time too. I printed the instructions and somehow the printer failed to print the one line that instructs the person to rotate the engine after doing one side. :cry: :lol:

I wouldn't go tighter. Loose is better than tight with the valves. Too tight and you run the risk of not closing completely and burning valves. Too loose is just noisier and maybe a bit of performance loss.

I would adjust them to .07mm, despite what that guide tjobowa posted says. Just don't adjust it too tight against the feeler gauge, tighten it enough so it takes just a *little* force to slide the feeler gauge out from under it, it shouldn't actually take real effort to get it out. However, you also shouldn't be able to slide the gauge back in between it either if you've done it right.

You should be fine as long as you're within 0.06-0.10 mm or 0.002-0.004 inch; those numbers are from the Honda Service Manual.

Thanks for the guidance. I borrowed a .002mm for a nieghbor, made the adjustment again, and now it all seems good to go. Trial and error, a little patience, and the correct guage, and it all worked out. Next project will be to remove and clean carburator over the winter.

As a side note, I purchased a halogen headlight from Jack's recently and I have to say "what a difference"...easy to install, looks great, and provides much more light. Rebel's a great bike to learn on - mechanically and riding. Heck, it's a great bike..period.
