Answer
Hi Garrick,

Are you changing the air filter or modding the air box too?
Either way I recommend getting a dynojet kit. These things make jetting easier.
You can find one for your bike here:

However, that being said, you can still change the main jet by itself.
If you are only modding the pipes and leaving the airbox, I would try the bike with the stock jetting. If it runs lean (on top) then try a DJ100 main jet.
If you are also adding a K&N drop in filter try the DJ100 and if that is too lean, try the DJ102.

BTW, you can order the main jets direct from Dynojet at $2 a piece and they ship them really fast.

Again, you want the 'DJ' style main jet.

Hope this helps?
