YZ Timing & Jetting

Recommended Posts

I checked all of the posts related to YZ timing and Jetting but, could not find:

I changed my timing to YZ spec. Now when the I open the trottle ( 1/2 to full open ) the motor burbbles (like it is too rich). I have the stock jetting. it sounds like the main jet - could be the needle also. What size main jet do I need?? or???

thanks
