Oh I am not up on the bugatti. After some more research I have found that Kwai has made turbo bikes that are slightly bigger than mine. Granted they are a bit older. But when you are looking at a turbo it's not so much the age of the bike it was on but the size of the turbo and the boost it provides. I'm thinking no more than maybe 6psi.

Things I know that will need to be done,
Fuel mapping
Timing adjustment
Inter cooler
Major engineering for intake and exhaust
Possibly re-gearing the transmission so the front and the back don't switch places, not to mention get the higher top end.

i wouldn't waste the time and material intercooling a 6psi system. your outlet temp differential isn't going to be that radical.

what do you mean by "Possibly re-gearing the transmission so the front and the back don't switch places,"? running a taller final drive is about all you're going to be able to do.
as far as timing and fueling, yeah thats a necessity.. you have to pull timing on boost, but on such a low boost system you probably might have to pull 2* and no more.. run a good fuel and you may not have to pull shit off it. i'd run stockish static CR for low boost so you have some balls off the line until the turbo spools up.

do any flow calcs yet to determine a compressor, wheel trims and A/Rs?

just in case you didn't know, i'm like.. the resident turbo engineering nazi. if i see someone is just planning to boost a bike with no thought or engineering behind it, i track them down and and beat them with rubber hoses. kirk adams, poofbgone and several others have successfully boosted 636s and they offer MANY many years of trusted racing and engine building experience as well.

Well considering im not trying to do this over night and I am taking my time to get it right don't take out your hoses just yet. I have yet to even purchase any of the required parts. All good things come to those who plan. Im sure im gonna have some difficulties along the way seeing as bike or auto mechanics aren't my forte. But I am mechanically inclined and determined.

you're totally backwards. bottoms are always primaries since they're under throttle plates.

depends on what your AFR looks like. it could be too much fuel. you can only trim injector PWM so much before it simply isn't going to spray effectively at the given RPM. and you can only tune pressure so far as well. a combo of those can sometimes get you out of trouble, but then you've got to make sure fuel pressure jumps back up to where it needs to be when on boost. you can go old skool with a rising-rate FPR, but with injection, it kinda sucks having to do that in the first place.

you really need to figure out what your AFR is, what your injector flowrates are, what the BSFC is, and start sizing the correct injectors for the application, which is pretty much dependent on boost and PR. in my sig theres the "how to" link.. in that thread theres an "engine related formulas" thread that has a majority of that math you need.

i'd suggest gettin busy on those numbers!

i can't make a judgement call without knowing what boost you're making, the turbo, the fuel type, the HP.. shit like that. i know nothing on your set-up.
