ok, for a friend. He just bought a 97. Kaw. 500. And when we get it to start it runs... as long as you can keep the throttle on. We have cleaned the carbs, not totally taking them apart. It runs perfect if we either jump it or get it started, but if you come to a stop it will idle down until it eventually dies (within seconds). Any help on what it can be before we take it to a shop and pay someone a rediculus amount to tell us something stupid and that is an easy fix? Maybe someone knows what it can be or has had this problem before. Please help us! Thanks all!

bump for help...PLZ

 

Check if the fuel lines are clogged or fuel filter clogged. Check air filter also. Then see if the gas tank is rusted on the inside... rust particles might get into fuel line. Recheck your carbs. Oh.. and also, check your idle. Turn it up a bit if it's too low. My CBR idles at 1.5k rpm when warmed with choke off.

 

will do thank you..
