will it work? i get 35mph from my cleared head (i removed the chamber), and am hoping the stock chamber will get me more speed.

Color shouldnt have anything to do with fit.. are you talking about the old yellow colored clones vs the newer blue ones? if so there shouldnt be any difference its just a diff colored shrouds and what not..

I dont smoke so its all good.. just a few drinks once in a while

what i mean by clearing the head is, i used a rotary rasp to remove the preformed chamber. i stayed with the stock depth, but removed all of the material to allow the piston to come into the head. if i so wanted. i haven't ran that head yet, but the 18cc head i did do a little chamber work on. so now i have a low comp, mid comp and higher comp heads to tinker with.

Certain clones have better ratio rocker arms in them, so watch for that. Are you running a tach or just assuming you haven't simply run out of gearing? The stock cam is worthless above 5k or so IIRC.

i've got the 1.3s, though the 340 rockers seemed better. i hear that the champion clones run a cheap roller rocker. i'm just building the motor for now. this is a semi offroad kart, that will still be used for children. the parts are cheap enough to tinker a bit. on the stands, she runs 45 to 49, on the street she was runnning 35. i guess i don't have enough cam/carb for her to blow, which is great. my speedo went out, so no quantatative data till i get it replaced. sucks balls. when i did ride in it, i was driving with a passenger, so perfomance was not expected, neither did it show. the belt kept getting ate up to. i forgot to install a spacer.
