dalegoldston Posted April 21, 2006 Report Posted April 21, 2006 (edited) Well I locked mine up last weekend. Dont really know what happened maybe didnt shake the gas good enough. But my question is what would a 420 bore and piston add for HP based that im at about 56 now. Can you rebuild after the bore or do you resleeve and bore back to 420 for rebuilds?

NYUK Posted April 21, 2006 Report Posted April 21, 2006 stock cylinders?stock stroke? will not equal 420. did you 420 it up on 420? Quote
dalegoldston Posted April 21, 2006 Author Report Posted April 21, 2006 wasnt sure I thought to obtain a 420 was just an oversize bore and pistons. No 4/20 for me but been there done that. Quote

dalegoldston Posted April 22, 2006 Author Report Posted April 22, 2006 So how does one obtain a 420 and is that setup good for all around riding from trails to dunes. Will the gain be worth the $. Quote
NYUK Posted April 22, 2006 Report Posted April 22, 2006 a dune port is the best bang for the buck, i have had a play bike with 75 hp. not ideal for trails, it was a ported 350 stock stroke on gas.it ran great for a long time.there are a few builders on here that can help. or call andy 616 642 6186.
