AKheathen Posted May 24, 2011 Report Posted May 24, 2011 well, first, yes, there is a nice jump in power/torque going 4mill, or bigger, but everything else- you need to have your cylinders done to match, and making the stock pistons work, is not the greatest of ideas....... short of it, get a builder and ask them. to make it worth while, it's going to run about 1200 give or take, and any short-cuts to just make it work are going to cost more, and make less power than just getting it ported. if you still have stock pistons in there, it's probably time to replace them anyways. go read up in the drag section, and you will learn a lot, and i'm not talking about skimming a couple threads for a couple min. do reasearch and learn. it will take time.

camatv Posted May 24, 2011 Report Posted May 24, 2011 (edited) send it to me. your gonna need diff pipes for drag racing also. you will probably have to change the entire bike up depending on how serious into draggin you want to go. or just buy my 485 and be done. it has a 4 mill crank......

Loc Posted May 24, 2011 Report Posted May 24, 2011 Buy a 421 cub kit and the bike will do you just fine. Easy build and not alot of money This setup could get you around the 85HP mark -Cub Cylinder -4mm Crank -Pistons -Head -Custom cut domes -Bigger carbs -Pipes (CPI, Shearer, Rockets) -Bigger Clutch Quote
Jereme6655 Posted May 25, 2011 Report Posted May 25, 2011 okay.......so if your askin what a 421 or a 485 is.....then im guessing you haven't been around too long or been doing a lot of research on here. it depends what you mean by "drag racing." if your talkin gjust racing your friends then its up to you what you want to do with power........but if your talking about actual sand drags then your a little off base with your +4mil idea...... your gonna get a BIG surprize when i guy pulls up next to you with a stretched frame and a +10 or +16 dm in the chassis and your gonna want to hide because of the embarrasment. the +4 is gonna be a formiddable trail bike motor. either way my suggestion to you is to hop on the site as much as you can and just watch the posts and read and do the leg work. alot of people wont respect you on here if your just want the answer without the leg work. and when i say do some research and ask some sensible questions.....im not talking about 2 days of research...
