What can I do to my GPX 124cc to make it run like a klx110 with a Trail Bikes 143 and V2 head.

146cc or 160cc bigbore kit and race head

Thats what I was thinking. How much of a difference is it between the 146 or 160 kit ? Which one is more reliable ?

The 146 is likely going to last a bit longer, due to the full-skirt piston, but we've been pounding a 160 with no issues. And, it pulls away from the 146/150 motors. Should be able to outrun your 143 buddy.
