Yea its 70cc and i got the billet head from rocksoild.Cause im from aus i got most of my stuff through them, i didnt weld the motor mount to the bike frame (it was on the fritz) Just 3 U bolts with some bike tire sandwiched in there. It seems to work well so i cant be bothered to go back and weld it now, i will wait till i need to take the motor off for whatever reason. Thanks
