Rm125 mid rpm bogg. HELP!

Recommended Posts

Can anyone help me out? I just rebuilt the top end in my 98 rm125 the other week.. Bike idles great, quick throttle response, pulls decent in the low end and mid throttle runs like shit like its still not warmed up and gummed up but anything after 3/4 throttle hauls ass. Can seem to get the mid range bog. Any suggestions?

I have tried going up one size on pilot jet and no fix. I have also tried lowering the clip on needle and still nothing. Powerband kicks in fine after about 3/4 rpms just runs like shit anything between 1/4 to 3/4. Thanks in advance.

Just a thought but inspect the throttle slide for damage.
