Well I got lazy, and did not document the build but I did finish the bike. I only ran into 3 issues when converting to the full C-one setup;
-The malossi gear box cover requires all new gears, which was a drag. It was advertised as compatible with stock gears/ratios. That's not true at all. Not the end of the world, as I was planning on up-gearing anyhow
-The newer "furia rosa" over-range rear pulley had clearance issues with malossi gearbox cover. I was a bit disappointed as malossi recommends this over-range in conjunction with all their other trick ass transmission parts. Nothing a little sanding disc action couldn't solve, definitely not ideal though.

I almost want to say that Malossi is aware this is an issue, and is now machining the backside of the pulley like this:

-Last, the c-one engine case has provisions for a true full bearing gearbox set-up. The issue is the bearing that supports the input/clutch shaft on the engine case side. It's just not included with the C-one case kit at all. Neither malossi nor sip acknowledged this.
Its a standard size needle bearing 12x18x12, plops in no problem.
As you can see it's not even listed as a spare part:

Other than that things went together pretty easily.
Mounting a radiator was actually not so bad. I found a good oversize l/h radiator for a Kx450f on ebay, and made some brackets from left over scrap at the shop. I'm using the malossi electric pump, this keeps running temps near 120*-135*f for the most part.
I'm also using a trail tech striker dash for voltage and temp readings. It was very easy to install. This unit is pretty dang good for the price
A'll said and done, this set-up is close to $2500
The pics are kind of ass, I'll take some better ones in the near future
