Added a comment about member blog 2003 CR125 Cylinder Head 9/28/2018 5:30 PM

If I was looking for a head for a CR125 I would be buying a VHM Head. The STD bike has a Metal Head gasket and tends to have detonation issues. When we raced the Bike back in the day we had to run the compression low or pay the price in Detonation and Head gasket failures. The VHM head has a two piece design and runs two O ring's eliminating the steel gasket. The alloy to alloy transfers the heat out of the head better and you can run higher compression to bring the power up to a more competitive level compared to the YZs and KTMS of the day.;

She is lean, piston is getting hot and the ring is moving in the softened piston and catching in the port. try leaded race gas and a bigger main jet.

Allways looks better if it all lines up but over the past few years there is some good evidence that the smaller boost port is better going by later KTMs...

Added reply in a thread Why would a factory team do their peg pins like this? 4/11/2018 12:55 AM

The Euro tracks some times have a bunch of rocks and the split pins tend to get mashed up and every now and then one or part of one falls or get pulled out. The euro mechanics like to keep the split pin up top where they can keep an eye on it and it's ... more »
