I have a stage 6 rt 70 on a drr quad.my son runs it wide open goes into a turn gits the throttle and it bogs. If he feathers the throttle he can make it stop. It also goes faster at half throttle then full. I thought it was too big of a main jet but so far I havent got it perfect.

Sounds like it's rich, may be right about the MJ being too big. What does the plug look like?

Ill pull the plug when I get home. I have kept going down on main jets but I feel like I get to a spot where it gets worse. Ive played with the needle a little but I just cant get it perfect. Leak down test passed and I have 165psi compression.

Well I have always ran this setup and the only thing different about this motor is the trenching of the case. Ive only been messing with these for 2 years and im still learning.
