another jet kit question

[jonnyp]

up here in canada theres not much to do when the snow mobile goes back into storage, till riding begins.
ive bought a hindle pipe/elbow for my 05 kat 600, and a k&n air filter over this time. will the engine run fine without adding a stage i dyno jet kit??

I recommend adding the stage 1 jet kit. What you have done is increased the amount of air with the K&N and Hindle therefore you should increase the fuel also by adding the stage 1.

thanks ill do that, any reliability issues as far as the motor is concerned

also once jetted would u have to return to stock jetting if an oem muffler was reinstalled??
thanks for your info this site rocks
