Raptor 300

How many of you all are, or have ran the 300cc kit ?

Hey Leager-N-ky,


I have tried alot of combinations and the bore & stroke to achieve a 300CC works the best. I don't advise a big 81MM piston to get 300CC.

Any questions PM me and we can discuss.
Thanks,

Have two

Starter is an issue on both but can be overcome with voltage

Both punched out to 78mm with plus 4 crank

Both have FCR

Both have plus 1 intake and have been flowed

Clutch needs attention frequently

Run very well if you have the time to put into maintenance, frame and motor not engineered for what is being put through these.
