660R stock jetting?

[RAPTIFIED]

I'm going to order one of your pipes this afternoon but need to get the jetting question out of the way, the bike is totally stock....do i need to rejet if i'm just getting the slip on? Thanks.

Yes, you will need to re jet with the slip on. The jetting that we used with our Raptor slip on was a 145 main in the left carb. and a 150 in the right with the fuel screws set to the highest, smooth idle. That was with everything else totally stock. Just to let you know, we are now offering our own power up kits that are available with either a K&N or a dual stage foam filter. Give us a call at 866 HMF PIPE for details.
