01 yz250f bog and idle hunting
Posted 30 April 2012 - 02:47 PM
I bought a 01 yz250f a few weeks ago and it had took about 10 kicks to start from cold. After you got it warmed up it started and ran well except for some popping on deceleration. I thought that I should try upping the jetting to a 48 and it didn't run well on that.
So after putting back in the stock 45 I cannot get it to run well again and have tremendous bog off the start and after revving the idle takes time to go back down and hangs at high idle levels
Thanks alot and any help will mean alot.

I think I might have found the problem.
When I started the work I replaced the stock fuel screw with a Tusk One.
I think that was a big mistake from my further reading on here.
Im going to put the OEM one back in
Yup....tusk screw didn't work on mine either, caused a super rich idle that I couldn't cure until I put the stock screw back in.
RM will give you a refund if you ask and describe the issue....but they deny there is a problem with them.

you don't have to send it back or anything....they will just send you a refund if you explain your situation.
