Got the motor out of its old home and into its new one today. gotta do a little adjusting at the yoke area but now im waiting for my swingarm to show up so i know its centered. Once thats done I can get the rails from jfab and send the frame to the welder. Once the frames welded I'm going to rebuild the motor so I have a new motor in my new bike.

Your making great progress.

Hurry Jerry, hurry... :-D

It may take Jerry a few days to get back to you but don't worry, he will  :-)

Well I got the shock linkage today so i can make sure the pipe is going to clear the shock but I'm still waiting for the swingarm to show up. It kinda sucks too as I have to go back up to college since school is starting next Monday. In the long run though it just means that I can get more stuff done on the weekends.

Well i cut about 1/4" more off the down tube and got alot more room near the cylinder head. Got the linkage on also today. Now im just waiting for the swing arm so i can center the motor left to right.

Okay guys since i got back this weekend I got quite a bit done. The swing arm and swing arm blot showed up but still no subframe so that pisses me off a little. I got the swing arm bolted up to the frame and checked the chain alignment to make sure all was square before made the measurements for the spacers in between the motor and the swing arm as the motor is skinnier than the swingarm opening. I still have not heard from Jfab as far as ordering some rails but once i get the rails it can go off to the welder to start making motor mounts and get this bike read for the track

Well didnt have any parts to work on my bike this weekend but I got the airbox gas tank and rear shock on the way.  I am still waiting to hear from jerry on getting a set of rails. In the mean time i can get my airbox boot adapter plate made and get the motor mounts made so when the rails get here i can have those welded in at the same time.

Well the subframe finally showed up today. After buying one on ebay and then having to draw a case against the seller and buying a different one, I finally got the subframe I needed. I only need to get a few more parts like the front and rear wheels, front suspension and radiators. I plan to put some seriouse time in on it this weekend to hope fully finish the motor fitment and then send it to the welder.
