143cc with stock carb?

Recommended Posts

Would that work at all? Anyone out there running stock carb with oversized piston?

Of so, what jetting?

Thanks,

Steve

When my bike ran it had a 143 powroll kit and a 110 main jet and ran ok. But since it was blown up I probably couldn't tell a difference between jets.:)

:thumbsup: I ran the stock carb for one year with the 143 high comp powroll kit. I think I ran a 107.5 main jet. Stock is a 102.5. the following year I ran it with a powroll 26mmcarb and the mid-race grind cam. It ran much better with the cam and carb but it was tricky getting the jetting close to right.

Just as an update, I'm running it right now with the stock carb, 110 main and it's running very good!

That's good to hear Steve47. They are fun bikes for track or trail!
