Anyone know engine idea's.

 

well you can't get more bottom end but you can make it scream. possibly beat your ds 650. check out aaen, hpd, and hot seat. a pipe reeds carb and some porting will make it fly

 

for 500 bucks you can do exhaust, port, wiseco piston kit and soem clutch work...thatll give u all around more power prob around 12hp all together

 

why stop there...you might as well stroke it
