9/28/2018 5:30pm
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...

5/24/2018 4:08am
I was around when the switch over to DLC from TiN started. we thought at the time there was no real world advantage friction wise and my feeling was it was a fashion thing... in the intervening years there has been issues with quality of many DLC suppliers and maybe the cost and hassle are driving the TiN band wagon...

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.

Guys that make and sell race fuel will tell you that..... True story a while back in the 90's the Factory Yamaha World Championship road race team was testing at a circuit in Sydney and had sent their equipment and fuel over for the test Sonoco was making a fuel just for them and shipping it all over the world...

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...
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 safe up there from rocks...

Back in the 90's we had some factory swing arms delivered to my team that the previous team manager had ordered. 6x swing arms showed up with price tag of $15,000 each. I freaked out and asked my Japanese boss to find out how the hell they could be that much. He came back with the answer that the price...

The dude is a Diabetic and has had some kind of low energy deal the makes training and racing pretty much impossible at a pro level. He has stepped back and runs a track that is very well liked a few hours south of Sydney. He doesn't have Aids....just a realy bad hair cut.

I have seen two bikes that made noises that the owners did not like. Boke turned out to be the starter idle gear and starter clutch. Both times we fitted up some parts from a donor bike and the noise dissappeared. Both times we couldnt realy see any problems with the eye except that there was a tad more clearance...

Ross_McWatters Added a reply to How are KTMs so light?

1/19/2018 5:26pm
Every part on a new KTM design is Cad designed and their revision of each product every few years they make changes reducing the weight. this and investing in the latest casting methods has payed off. The Jap bikes for the most part are the same as they were 10 years ago and they haven't pursued the technology like KTM...

You mite find of those 52's have Alloy lower tubes, not steel. I believe the Black DLC coating has to be applied at a very high temperature inside a vacuum chamber. This high processing temperature can affect the tempering of the Alloy tube an maybe make it stiffer and more brittle. Just a theory the DLC is good for friction...

For 98 I would just buy the vortex and its preprogrammed maps will be fine. I am a fan of the product I feel they come set up better out of the box better than the get.
