More photos from this weekend. Old photos were moved into phase one on the site, phase 2 is now only for the motor mock up. I'm sure you can see new beer cans :). Photo is of my brother not me

Dude, things are movin for you M8. ( Ive been wanting to type M8, thats cool) Check mock-up with pipe , down tube looks like it could be a problem, I used 7/8" DOM Round Tube, and had to put a slight bend in it. Mount back motor mounts and align in 3D. Tack that then build down tube and front motor mounts. Sprocket,chain,swingarm pin, and Motor pin have to align in 3 dimensions. After that move foward with you mock-up. Good Luck. Our Apriliasaki goes a true 100 MPH with 17/44 gear and other tricks. Every ounce adds up.

Our plan for alignment is as follows, finish the two mounts in the rear and bolt them to the motor, roughly align the rear of the motor to the correct height and distance from the swingarm and mark where to drill two top holes in the mounts to run a long bolt through the stock RS50 upper engine mount . If the two mounts have the exact same center to center hole distance, and the top of the mount runs through the origional RS50 mount, then the motor will sit essentially square in the chassis. We'll create two gap spacers to distance the motor from the swingarm the same on both sides, and then adjust the motor side to side to line up the sprocket (which should be nearly perfect from our previous alignment tries. Then once that is all bolted together, put the pipe on, lift up the front of the motor to desired height, and tack on the front mounts to the down tube. We're hoping this will hold the motor in the chassis securly enough to connect the two halves of the engine subframe and create a strong bottom motor mount. Then we'll remove the temporary rear mount and construct a stronger rear mount. I'm not to worried about the weight of the assembly since my weight is what will really be holding the bike back in the end. We'll have to see how this plan ends up working.

I was wrong about the pipe. I just went and checked. Mock up the radiator
also,even remove fork spring and check at full travel. Mine is very close. also
the Rad, cap is an issue. Im proud your really going at it. Dont give up like so many do. I just installed a Daytona dig Temp gauge. made my on sensor tap. Works awsome. Good luck.
