[QUOTE="Bud-Man, post: 145108, member: 20830"] I installed the Pro Circuit T4 silencer and changed the jetting to an EMN needle-#4, and a 168 main. I also dropped the gearing to a 13/50 combination, mostly to make it easier to ride in tight off road stuff. I may cosider adding a few teeth on the rear sprocket for laughs. As it sits right now, I can out run an '01 CR250 in 5th gear....and I still have 6th to go :cool: ! Coach, what altitude are you at and have you fiddled with the jetting much, or did you just install it and go? (I installed my jetting as per recommendations and it ran great , so I haven't messed with it yet.) Also, I'm a little confused on the crank breather thing; you plugged the spigot on the carb and placed a filter on the breather hose which you place under the gas tank, correct? [/QUOTE]
