Hope I can get some help here!
My bike is Vulcan 800 B from 1990, I discover it has a hot or warm start problem, the bike start real OK when it stay cool(cool engine), but its difficult to start when its hot, just like this morning, I drove to gas station for fill up, it was a pretty short trip, a few min. ride, then the bike don't want to start!!?
I need to force it by keep pressing the red button...
last time was after couple hours...it happened the same??
can anyone help me in this problem? should I change the spark plug? or something else?

Check the valve adjustment.

Can you tell me how?

If you're mechanically inclined, and want to work on the bike yourself, the first thing you'll need is a good service manual. If not, then you should probably take it to a shop.

Belly up to the bar at a Kawasaki shop and crack your wallet. Buy a KAWASAKI factory manual. Haynes and Chilton are only for bathroom entertainment.
