Hey whats up new to this site. I need some help please my 95 zrt800 will not idle down. it idles at 3000ish until i bump the choke it will drop down to 1200-1500 sometimes it will stay there or it will rev back to 3000ish help me please .
It sounds like a lean idle condition. The first thing you need to check is the intake boots. If there is any signs of cracking it may be sucking in to much air. If the boots are ok, the next thing to do is adjust the pilot air screws to fatten up the idle mixture by taking away a little air flow. This should be done using a Uni Sync or other multi carb syncronizing tool.
If it still does it after the carbs are syncronized, you may have a crankseal gone bad and sucking air into the crankcase.
