Big Dreams. Small Funds!
I guess its time I finally introduce my project here. I've been lurking around for over a year.
Bike: 1993 Honda Nighthawk 750 with a 1998 engine(no clue why)
The Plan: A radically customized homologation of a retro modern cafe racer/brat/thing... IDK what to call it. Hence the name. I intend to borrow the rear suspension from a Harley Davidson (dont oust me yet) softail and locate the shocks under the belly of the bike. Doing so will free up the room I need to do an underseat install of two tiny turbos (I've done the calculations). It will be intercooled, and will run with GSXR throttle bodies and microsquirt EFI. It will not be a fast build, but the end goal is a production quality bike. 100hp at the wheel. And, completion of my most ambitious mechanical project to date (not my first).
I picked up the bike for $500 from my wifes boss, it had been sitting for 3 years. Hooked up some power to the battery, turned it over for a few second, and she fired to life. Only on 2 cylinders though, and then 3 but never 4. It had pod filters that I could pull off by hand, all the plastics were broken, cracked, and barely hanging on with zip ties. The grips didnt fit, the handle bars were too small for the clutch and brake bracket so they were loose, the headlight was falling off, wires were cut, it was a basket case.
So I removed everything that was damaged, broken, or useless and was left with what you see below. It took me a year to come up with a solid plan and do 99% of the research to get started, but now we are there!
The turbos chosen, after hours of calculations, are the Ecotrons VZ21's. They're knock off IHI RHB31s. I'd prefer to use the IHI turbos, but I cant find even one much less two! At some point in the future they may get swapped out with some high quality Garrett GT12's, but that's way off.
The sketches below show the plan a bit, everything circled in yellow is gonna go away to make room for the rest of the plan. The blue will be added to the swing arm, and the green is the shocks.
The final plan has been slightly sketched out in the last pic. Also, I know this isn't everyone's cup o tea.
Details:
Brat style seat for 2 up with removable fake "hump" for solo
Frame, engine, center of wheels, calipers, and other bits powder coated anthracite grey
Tins painted Ford Ruby Red
Clip on bars with all wires hidden with bar end blinkers
Headlight/gauge cluster with two projector LED headlights
3" extended swing arm with fender added to swing arm
