Last race season went well. I improved each race except for the one in which I was hung over.During the first race weekend I discovered that I had the bike sitting too high. The swingarm is from a 1983 GPZ 750 with eccentric adjusters. I turned the adjusters around which raised the rear approx. 3/4" . The front forks are from a 82' GPZ 1100 which are about 1/4" longer than the J forks. I had the bike on scales and that's why I went the way I did. On the track the bike felt awkward. I decided to turn the adjusters to their stock position and drop the forks 1/2" in the triples. This made an immediate improvement. In my shop prior to the next race weekend I decided to have a close look at the fork internals. Race Tech doesn't recommend any spacer preload on there springs and the previous owner of the forks had 3/4" of spacer preload. I removed 1/2" of preload and this also made a big improvement. During the last race weekend I experienced two troubling issues. At Saint Eustache ,Quebec in whats called the bowl I hit the frame lug for the side stand. This moved the whole bike and for a spit second I thought I was going to go off the track. Out came the hack saw and off with the lug. Later that weekend while racing I felt the brake lever come back a little further. It only did this 3/4's into the race and as soon as I slowed down to come off the track the pressure was back to where it should be. Thank god I still had good brakes. The only thing I plan to do is rebuild the front master and work on the Cams. I will replace the stock exhaust cam (KZ 1100R .380" lift 300 Degrees duration) with a smaller 82' gpz 1100 cam and degree the cam so I will have better mid range.
