Hi,

I'm sure this topic has been covered before but I can't find it so does anyone know a good starting point for jetting a keihin carb for a 125 pro?

The carb is off a 300 pro so will I also need to change the silde which is currently a 3.5 and the needle which is currently a jjh?

Any recommendations / experiences would be much appreciated

Cheers,

Mark

the 3.5 slide will be fine, as the 300's should be using a 3 slide instead. the needle will be perfect, jetting will be fine also, i used to use standard jetting on my old 125 & it run perfect, to be honest i wouldn't change the jetting as long as the bike runs ok.

What main Jet & pilot jet is in the carb at the moment?
