New YZ250F - Very hard starting

Recommended Posts

The new bike starts fairly well after it's hot, but it takes a lot of kicking when it's not warmed up. If it starts, but dies when the chock is turned off too soon, it takes forever to start. I'm in Alabama, so the weather's hot as blue blazes right now.

I can't see how the jetting could be that far off. The fuel screw is out about 2 1/2 turns. My dealer did the valve switch. Do you think they did not get the valve clearances right and that is likely my problem?

By the way, the bike runs awesome once we get it going.

Check your valve clearances to ease your mind,it is your bike,check them and get back.

Common problem on the 06 is the float level is to high. If you have ANY gas dripping when you are kicking, you need to adjust the float. It is your problem.

Try leaning out your idle circuit, i.e. set the fuel screw to 1 1/2 or 2 turns out and/or use a PJ that is one size smaller. Leaning out the idle circuit will help with starting but may cause some deceleration popping which is OK to have...
