Ok.. second day impressions...
I put on a total of 50 miles on this afternoon after a valve adjustment and carb sync. (i know its kinda pathetic, all i had time to ride today)
Well does it have more power you ask? Yes. You can feel more torque down around 4-6k than the 600 had, very usable power around town in traffic. The power feels more linear and seems to pull very nicely from down lower than the 6. The engine doesnt feel peaky like the old one did. The 600 you could feel a definate power surge around 7k, the 750 seems to pull hard from lower without any surges all the way to redline. I did a top gear roll on from 70, it pulled to about 125 at 10k very quickly, had to shut her down, i was making good ground on the guy in front of me.
Im still using the B6 header. Larry do you think the 12 header makes that much difference? I may have to look into that down the road.
Im using the 600 32mm carbs.. Running 105 mains, two shims and two and a quarter turns out i believe. I think im going to have to go up on the mains another step, maybe try 107.5 or 110s. I think there is still more power to be had from the top end with some more tuning. Planning a dyno run in the future to see what im putting to the ground. The intake boots on the 750 where larger than the 600 since it had larger carbs, but they where in better condition than my 10 year old 600 ones. The bigger ones will clam down enough for the smaller carbs if you use the smaller 600 clamps, the carbs dont snap into the boots like the used to, but i have no vaccume leaks so far. I will be keeping an eye on them though.
There is definately a difference in power, I cant imagine what you b12 guys must feel when riding yours! makes me cant wait till i get out of college and can afford the 12. Over all i think the power increase coupled with the light weight and very flikable 600 chassis should make a great road bike. Next mod is suspension.
Write up to come soon with pics!
