Well I went out last Saturday. What a disaster! The track wasn't prep'd at all and the bike (I lowered the rear 4 + inches and replaced the shock with a solid rod, strapped the front and pushed the legs through the yokes 1.1/4 inches) was an animal, the back tyre was hooking up and letting go in quick succession and the front didn't like the expansion joints in the track at all. The vibration was so bad it was throwing me back and forth like a very fast seesaw. The second run with lowered tyre pressure I just span out for about 30 ft before hooking second gear. After that I went home in discust. The track is usually good and grip juice is sprayed often through out the day but it wasn't happening. SO I have decided to concentrate on perfecting the engine management, there is a lot of room for improvement low down. The MAP sensor needs a voltage cap and I have a device coming to sort that. The Lambda sensor is getting to much reversion from the short open exhaust and just gets lost at idle, so needs repositioning or a baffle putting rear of it. These exhaust guys who are coming out with stubby cans don't know what they are getting into with this bike I can tell you.
