it wont hurt it if you dont but it will perform better if you do rejet to the pipe.

ight thanks i wanted to no cause we cut the spark arrestor and the baffle outta my stock pipe and i heard it will destroy the rings and i didnt know if it would do that with after market pipe

ill ask the guy at the shop when we order my tires

yes, you need to rejet.

maybe 1 size on the main and leave the pilot alone for just a slip on.

 

[XxblasterboyxX]

do you no like what size the main will need to be for hmf slip on?

one size up on the main and maybe a clip on the needle, from the factory those bikes are jetted extremely mellow.. get a full jet kit and screw around with it for a few days, u can real wake that bike up with some precise jetting

yup one size on the main and adjust the airscrew a lil

I would suggest just waiting and saving until you can afford a full system. A slip on with improve sound but thats it. You won't notice a power change much at all.

i would but i really screwed up by cutting my spark arrestor off of my stock pipe and now its gonna eff up the rings

Yeah well get a slip on for now but MAKE SURE YOU GET ONE WITH A FULL SYSTEM OPTION! Like get a pipe that can be sold as a slip on or full system and when you get the money buy a head pipe. My advice, go Yoshi or call Tom Carlson at TC racing. He makes one crazy 400EX pipe.
