I bought a Raptor and the guy said it was bored .050 over. How many cc's do I have now?

 

well, it will gain about 30cc on a .060 bore, so probably like... 25??

 

so it's like a 686

 

Thanks guys, that helps out a lot. I think I got a great deal on it, has lots of engine work, port and polished head, hinson clutch, hmf exhaust, k&n filter, airbox removal kit, jet kit, dial a jet kit. Any idea about how much horsepower I might have with these mods? I am only 5'4" and 160 and it is really hard for me to keep the front end down. It is really powerful to me, now I think I'd like to widen it a little, any suggestions for not too much $$$? Thanks again for the help.

 

your probobly in the 55hp area. you might want to ditch the Dial-a-jet and just get it jetted real nice, alot of problems and horsepower robbing from dial a jet. also, try getting an exteended axle, that takes all the tippy-ness out of it. Try www.rockymountainatv.com they have an exteended axle with a lifetime guarentee for 200$

 

how does the dial a jet rob horse power?

 

if you dont like it wheeliing all the time then either gear it down with sprockets or getting a longer swingarm will help a little.

what is dial a jet? is that the thing that makes it so your supposevly dont have to ever rejet cuz it changes automaticaly? i can kinda see how that would rob horsepower if its constantly changing the amount of fuel.

Unless my math is wrong it should be about 676 cc.
