jetting 200x

[bakeban]

i have an 84 200x and i put a 50 over piston and it has some sort of megaphone freeflow exaust. it runs great but but when the throttle is cracked or i am just kind of putting around, it cracks and pops and cuts out. it runs like a stripped ass ape other wise. i was wondering if anyone knows if i need a bigger jet in the carb. it has the stock jet.
thanks

Probably need to adjust the jet needle clip position. Try one notch at a time and see what happens.

thanks. i took the needle out and noticed it was a notch rich. so i put it back to where it was suppost to be and it seems to run alot better.
