motocross in a box
This cynder kit is awesome. Run it with a tuned exhaust and a 90 jet for some serious fun. Cynder overhang is something else at some points there's only 1 mm of gasket face sealing in all the boom juice. Looks like il be porting in the not so distant Future. ( tip use play putty to stop metal dust from entering the crank while porting)
