    Some snaps from Tustin yesterday

    Well I was pleased with the setup of the sled as my starting point. She went to 8,400-8,500 and stayed right there thru all three runs. I ran three runs 92.6/89.7/92.8 ... Ya I know, they suck. Traction was a HUGE problem. She lit the track up all three times. The second run I really had...

    Slightly shorter belt, any advantages?

    My RX1 improver seems to be leaving a lot on the table as far as I think. When I got it there was a 89L belt on it. She started to let go on the second run I made with it. I had a brand new spare 89L off my 600 I put on it. Sat I noticed that after the first run it was creeping forward at...

    I Made Choice

    I Made The Choice Well I made the decision to try my luck in the racing circuit. I just purchased a 2005 Yamaha RX1 Improved Stock, completely ISR legal turn key sled that was Hauck built from the cases out. I also got another Vmax4. A 1992 with under a 1,000 miles. Now I can race prep my...

    Vmax Comparison 95 vs 97

    Well since I had a day off due to snow I decided to do a comparison test. When I took the 97 SX700 out the last time I was somewhat satisified with the ride and handling. This morning for sheets and grins I removed the rear shock as I was curious as to what was in there and what the settings...

    Vmax's can be an addiction

    well, since I finished up the 97/600 on Sat and ran her for a long run I'm satisfied with the final product. Now while I'm waiting for my 750 parts I decided to start another project. I don't know what the PO was thinking but he had a Viper exhaust system on it. Kinda hacked it in there. I was...
