2-Stroke with hot starting problem
Posted August 09, 2010 - 04:45 AM
When I first got the bike it wasn't great at starting cold either but after a carb clean and fresh fuel that problem was solved. Since discovering the hot start problem the only thing I've done so far is change the spark plug which seems to have helped a little.
What things would you recommend checking first? Anyone else had the same problem with an RM?
Failing suggestions on how to fix the problem any exercise recommendations for the gym to build good kick starting muscles?

Perhaps fuel flow is stopping somewhere in the line. Check the cap breather tube. Check the reeds, they can cause all different kinds of problems. Have you checked for spark when it's hot and not starting?

What should the compression reading be for a bore in good condition?

Not sure. I imagine it depends a bit on your year. I have a 97, and a fresh topend has 185-190 PSI. I would think things would start going south near 130. (I have an old RM that is totally and completely worn out and it still shows 100 PSI)
Cool, mine is a 98 so I guess it'll be similar to yours
