BBoy69 Posted July 18, 2019 Report Posted July 18, 2019 I have a scrap motor that my buddy sold to me for 400 bucks has a blowed top end but I’m thinking of building a wild motor out of this. The motor will be on pump gas 93 octane. All engine parts will come from either HJR F.A.S.T or Redline Racine .I am thinking about getting a ported 4 mil serval or a unported 4mil cheetah cub. I’ve researching the cheetah pv setups seeing that the cheetah pv doesn’t have the light switch that the cubs do and was wondering what advantages would the cheetah pv have over the cheetah cub. I know it’ll be more expensive. And this is mostly for back road ripping or dirt road ripping. Quote
Tedder Posted July 18, 2019 Report Posted July 18, 2019 My son has a ported 4mil Serval that runs great. 90% of his riding is back roads. Really fun bike. Quote

SKEETER Posted July 18, 2019 Report Posted July 18, 2019 It makes your serval, have a cub top end. With a lil thingy that opens/closes the exhaust height. Quote
