I just put the qs1 pipe on my 05 rancher and was wondering where to start with the jetting any advice appreciated. thanks

 

TAKE IT TO A MECHANIC!!! I had the same problem with my Rubi. I must have taken the carb out and messed with the jets and air/fuel mixture ten times and still couldn't get it right. It is a pain in the a$$. I would suggest doing like I ended up doing and let a mechanic do it right. I had it close a few times but it is like night and day the power difference once I got it back from the shop.
