Finally got to put some miles on today...108 to be exact. Runs well and pulls hard all the way up to 7000rpm and stops saw 7100 on a long pull but it just creaped up the extra 100. (I should be between 7300-7500 on a 04 zr9 I believe) I am runing the cat red white in the middle hole, to adjust my rpm do I move the spring back or forward a hole? On a long straight away I saw the same speedo speed that I was getting last year so that is fine not really looking for much more top end anyway. Secondary heat after a 40 miles none stop high speed run was good (better then stock), was able to put my bare hand on the secondary just warm to the touch. Need to do some more work but for the first run I'm happy.
