One word of advice m8, do not buy parts from ebay as it will only cause u problems. Better of buyin quality parts from one of the forum sponsors. You will be thankful in the long run.

yer k i think ill try that one then...
would it fit my 47cc?
Also because it has a full circle crank and different piston would it change the engine compasity to like 50 cc or somethin??

Also how hard are they to install??

Also would i have to break in my engine again?

hey dude yeh try the one in ya link or you can grab my last head kit

lols yeh you will have to break the new motor in on 25.1 or 30.1 for atleast 1 tank just to bed the rings in and get the engine nice and smooth once you do it let us know how it goe's

It might be a while cuz i gotta re-assemble my bike before i can ride it...
the frame is stripped bear because im modifying it to fit a full fairing kit on the half fairing frame...

Should look awesome..
Thanks for the help..

EDIT: would it change the engine compacity to 50cc or somethin??

50.1cc's i think if its a 33mm crank there are bore & stroke calculators or CC Calculators on the net just find out crank stroke & id say its a 44mm bore

some other factors like CC of head come into account but thats close enough
