Recommended Posts

Ok,so my bikes been acting boggy,I've messed with the clip and the air screw ,nothing has help completely,so I've narrowed it down to jetting.i pulled my carb and the main jet says 360rd 633T_0 .so my question should I go up or down on the main.im at abount 7500 ft obove sea level located on the colorado border.thanks for your opinions.cr 125

Why would you change a main jet to fix a low end bogging issue ?

If it otherwise ran fine before on the same settings and, in the same conditions (ambiant temps & elevation) the jetting isn't the problem.

 

Jets don't all of a sudden go bad (unless they plug up with gunk)

there is a multitude of other things to rule out before you start re-jetting or fine tuning an engine that suddenly runs bad.

 

For recommendations I'd say start with stock settings and go by the service manual's jetting chart for elevation compensation.

I also moved about 5000 feet so yeah,conditions changed.

what works at sea level - 1500 ft would be super rich at 5000-7500 ft

pilot , needle and clip , and main jet would all need attention

higher the altitude the lean the jetting

hotter the temp the leaner the jetting
