Sorry for no dyno charts at this time, but long story short, I (with the help of Sean of course) finally got my vmax made into a 1500! With the new higher compression pistons, I got the assembly balanced, ported my heads and v-boost manifolds, and used Sean's bigger 5th gear. I started it up, drove next door to my dyno and carefully (warming up the motor) loaded the motor harder and harder while watching the afr. After a dozen or so pulls now hitting as high as 8,000 rpms, I decided it shouldn't stick a piston if I go on the road for a test run. From the get go, the afr is in the 9's when floored until 6,500 or so. Knowing that I'm more than safe, I put on the helmet etc, and hit the road.
While already driving away in first gear, whacking the throttle will totally shread the tire and/or sky the front end it a split second (careful who you let drive it...skilled buddies only). In second gear (being extremely rich) starts to float the front end. I was not beating the crap out of the bike. I'd go in 4th gear, crank it up to about 7k, shift to 5th while coasting back down, down shift to 4th and do it again, and again, and again with little gentle cool down cruizing for a half minute in between.
I think every gear from 1st to 4th takes the same amount of time in between shifts. Very quick acceleration! When shifting into 5th, I just start to laugh because it is such a great match for the highway and it's new found power! I'm not claiming the hp is going to be as high or higher than the average 1500's, but whatever it's at now is more than satifactory. The fun factor is exactly what I was hoping for already! Once broke in and then jetted correctly, I think it is going to be quite a handful.

Thanks Sean for all your parts, guidance, expertise, etc! I'll try to leave you alone for the time being while I break it in and play with the jetting little by little. Marc Matczak.
