Thumper Racing 730 kit
So as you all know, I have the kit. Got it back this past friday and wasn't able to ride it. I was there for the final stages of putting the head on and stuff, and damn stripped the nut to the outside of the crank, so the valves are off a tad until I can get a new cover bolt (already ordered).
I will just say what I needed done to prevent creating another thread. I blew the oil ring of the old piston plus a knick in one of the compression rings. Don't really know how, but it happened. Also, the crank where the wrist pin goes in was scratched up a bit, so I got a new crank.
So here it is. I did a lot of stuff to this bike besides just the kit, which I will disclose at some other time. With the kit, I got a stage 3 cam, and the place was suppose to charge $405 for the kit and to bore out the cylinder, plus $185 for the cam (which is a hot cam). Anyway, they called me up and said I owed $490, which was awesome, it was 100 less than I though. Turns out they didn't charge me for the boring, the kit itself was $285 with out them boring it out. I also talked to the guy there quite a bit, and he is very nice and informative.
So with everything installed, I finally got to ride it. It is a lot harder to start. I dont know if it is b/c the starter is having more of a problem due to a higher compression, or if the starter is just going. It has tons more power than it did with just the big three. I was ripping around in the yard and the rear would kick loose in 3rd and 4th a lot easier, and it was way easier for wheelies as well. Overall I am pretty impressed, with the price it was about as much as it would be for just getting the OEM piston and rings. I can't think of much more to write, so if anyone has questions, feel free.
Oh yeah, it sounds a little meaner as well.

Yeah I did. Plus bigger valves, I just didn't want to get into all of it here. Kind of wanted to wait to get to a dyno.

As for the DYNO, I have been looking around here and there, trying to find one closer in my area. So hopefully in the next month or two.
