Ya, Basically there's definitely a noticeable difference even slowly accelerating with the new springs. I'm not very qualified to give out alot of info on this setup! I'm good friends with the mechanic at my Kawi dealer and he knows that I'm into low end power and very rarely do I hit 50+ mph, so he said this setup would be perfect for me. my 650 will wheelie very easily now even on wet grass where before the front end would come up about a foot, now I have to let off the throttle when I pin it because the front end wants to go right over. I'm sure someone else on here with this setup can give you a better idea on this setup, but from what I know this is for low end only because my top speed is basically identical. my speedo reads 105 km/h (around 63mph) but I also have 27" mudbugs on so I'm probably doing a little better than that. It's the time to get there thats improved up to about 45mph. my dealer took it out and said it was doing 81km/h where the stock ones were doing 70km/h....not sure about how many feet to hit this speed....(very quickly) but thats about a 6 or 7 mph gain over stock. not sure if this helped any but the low end on this bike is really impressive now. Good luck with your setup.

 

The Dalton clutch springs and weight work awesome. Before I installed the kit my p650 would only turn about 5500 rpms, after it would turn about 6800 rpm until the over rev. I noticed top speed was the same a constant 69 mph on the revlimiter. It ran 71 with a new belt. I was also runing a 360 belt with air box mods and 8* timing. In the next 3 weeks I will be installing the kit on a p700 will keep you posted.
