Won't idle especially when hot.

My New 2009 Suzuki DR-Z 250 won't idle. I have tried adjusting the idle screw & still wont idle. Is the idle jet blocked? Thanks Matt

Won,t idle dies out when you stop


this sounds like a carby problem as it maybe the float sticking and over fueling ,have you noticed any fuel leeks ,this could just be a cable adjustment or idle speed adjustment ,it could be a blocked low speed jet in your carby ,try a few simple adjustments first if not it may be a job for your motorcycle dealer as they have the testing equipment ,hope this helps cheers pete

It won't idle, having it on choke makes it shut off, sounds like it's running too rich.


Clean the caburator especially the idling speed jet. adjust the air valve as needed.

My bike started running bad. Only idles with choke


Recheck the float level, adjust if necessary.
Reblow the jets with compressed air.
If you have tampered with the air-mixture screw you will have to reset it too.
Standard setting is all the way in ...slowly as not to damage the tip, thn outwards 2 & a half turns to 3.
Hope this helps!
