Kick starter shaft problem, Anyone have this?

Recommended Posts

Hi everyone, I have been having a very weird problem with my YZ125, and it has broken 2 kick starter shafts in the course of 2 months.

This started happening after the installation of a set of UFO frame guards. (the starter itself sometimes would scrape against them).

This also happened when it was about 20 degrees F

I had a similar problem on my yz250f. I had an aluminum frame but was using a kickstarter from a steel frame. If the starter is on the wrong splines so kick starter is too vertical when all the way up you'll break shafts.

I've snapped one on a 100 mile ride I was 20 miles from my truck. Broke that whole case. then it started down pouring. Was a fun day.  I ended up jump starting it and road back no problems but I was definitely skeptical of running it
