What all would have to be done for an F4i to hang with an R1 or comprible (both sides of the spectrum 1/4 drag,top speed?Just curious. And Im not talking about gettin wild with a turb or nitrous. Just usable power.

 

thats gonna be reeeeaaal tough, as the R1 is a liter bike... im thinkin turbo would be necessary prolly :S I dont know if an f4i could hang w/ the r1, due to its huge hit in the CC department... but i dont really know a lot... so its prolly possible :S


to sum it up... most likely a lot

 

Well it would need an additional 400cc, there is no replacement for displacement!! And in 1/4 mile times displacement will win with equal riders. The bigger the motor, the more torque; and the more torque the faster it will get to a certain speed/ destination

 

haha, you are really going after a litre bike huh. You know, you COULD buy some better forged pistons, and rods. Then you could put a good shot of nitrous to it. Wouldnt be as fun as a turbo, but you wounldnt be fighting the front end like you will on a turbo bike.

 

just plain nuts for even asking that question. Just get a 1000 if u want to hang with the R1.

 

Solid rocket booster and parachute. As has already so eloquently been said, there ain't no replacement for displacement. Your best shot at an R1 is on extreme twisties where his power can be a disadvantage if misused. Sorry, know that isn't what you want to hear.

 

I think Iv got access to a couple of surplus JATO rockets.. Each one puts out like 3000 ft/lbs of boost. You think tahll be enough?

 

JATO bottles are the ****

The closest you could get without nitro ..
port and polish. piston/rod/bore kit.
cams. intake and exhaust. sprocket set up for 1/4 mi.
slicks.
I would go with a supercharger rather than a turbo for the 1/4 mi.
A turbo has better performance but they have to 'spin up' based on exhaust flow.
A supercharger is run on a pully system. The fow is there waiting.
Also, an air intercooler and new air flow sensor for the S-charger.
Ultralite frame kit. Ti or carbon fiber rims.

This will get you close, if not next to a STOCK R1. But you would be able to buy 2-3 R1s for the price of admission for the 600cc mods.

 

I don't know who you all have been riding with but my 2002 f4i with exaust and a pcIII will hang with a r-1 all day in street action (I do it every weekend!!)

 

Yes, you hang with them street riding meaning probably you're a better rider than whoever you ride with. The original question is regarding 1/4 times and top speed and I gotta parrot, there aint no replacement for displacement. So my anwer would be change every single part of the f4i to a part from a 1000rr, then you could hang with a r1.
