jet kit ?

[edogg]

i have a hmf exhaust on my 08 525s. does anybody know what size jet kit to put on there

i talked to a tech at hmf and he sent me a 150, 155, 160. the stock one was a 136. i installed the155. it was pretty simple. it  made a huge difference. less backfire and more throttle response. it was only 16 bucks too

Im running a 170. Ive got a muzzy on it and i removed the air box and put on a K&N air filter so it could breath. If your going to be doing more modifications to your quad in the future you might want to get a kit that comes with a bunch of diffrent ones. here is a link to the kit i used.

my buddy just bought a ktm 525xc. his cam stock with a 170. to much for mine cause its a straight axle 08. the airbox is too small. that ktm and the irs have way better airboxes.  they dont even make an aftermarket filter for the 08 525s.  mine runs great right now.
