What would have to be done before n F4i could hang with an R1?

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 shit

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.

You have two choices...pray real hard until you fall asleep and start dreaming or just get an R1.

My personal opinion is liter bikes are for lazy people. Because like i said if your in the right gear and are concious of what gear you are always in you will be right there with a r-1. If you have a r-1 you can just roll on the throttle for power, thats just lazy and a waist of money!!

Haha, thats a new one. You could also put a turbo on there and then you'd be with an R1. Im not sure how the gearing is though, as in what the top speed is limited at with stock gears.

I want some of what some of you been smokin. Look, 600's are pumpin out 110 hp compared to a 1000's 155 hp. With a grand total of maybe 40# or so difference in weight there's no way a stock 600 will 'keep up' with a stock 1000. If you're keeping up with an R1 then either you're a much better rider than he, you got some power mods or he's not really racing you. A Harley riding buddy once said my old turbo busa wasn't so bad cause he was keeping up with me. Truth be known I was riding with him. Gee, not a lot of glory in kicking a Harley's ass with a 300hp busa. Of course after he said that I pounded him the next time out.

So, like a lot have said, power mods. Nitrous, turbo, stroker, something along those lines. It CAN be done though.

Well anything is possible if you have the time, and the MOOLA!! It is not financially feasible to do, as stated a few times in this posting, you could buy a R1, or 2 or 3 of them for the cost needed too achieve this goal..stock for stock in a 1/4 mile race there is NO CONTEST with equal riders..now if you have a 16 year old with a learners permit on the R1, and proffesional drag racer on the 600; the odds would be different!!

Well I'll tell you this Mr "Ex-Busa" You bring your liter bike down and we will ride all day, not once will you leave or loose me. Thats only with a slip on and a pcIII on my f4i

Wasn't flaming you or your bike. I understand cc loyalty -- but here's something to consider. If a 600 really could hang with a 1000 in all conditions (you live in FL? Home of the 2 mile level straights?) then why doesn't Yates or Mladin or Duhamel ride a 600? It's lighter than the 1000's everybody else uses. They don't even ride the 750's anymore and the 750's that do run aren't winning. The 1000's are also setting track records everywhere they go.

The biggest problem most of us have with the 1000's is actually getting the power to the ground. That was always a major concern when I had the Busa. The bastard would smoke the tire at over 100mph on dry pavement and wheelie in 4th gear all on throttle alone. In that respect if you are able to use all a 600's power then you'll have an advantage over a poser who shifts a 1000 at 5000rpm.

The 600's today would easily beat the 1000's of a few years ago and I have nothing but respect for how fast and well mannered those little beasts are. But before you go challenging everybody on a 1000 to an all day race go ride one. Preferably a Honda -- they just put the power down so smooth it's scary. I promise you that when you get in the plus 8500 rpm zone you'll understand that there is a big difference.

dude, i dont think that was a challenge or anything man. chill. no one ever said you weren't a good rider. we're talking straight up bikes here. there's no way a 600cc bike can overtake 1000cc bike. "you cant make something out of nothing" law of physics. even with a slip-on and pc, those two things alone wont make enough power to cover the 40 cc diff.

im sorry, i just looked at this post. im having a hard time with it. there is no way at all, a 600 fi would even come close to a 1000. well if the guy on the 1000 stalled maybe. im not going to be an ass or challenge anyone to a race but lets just be real for a second. my brother has a 600 r6 wich is a very fast bike, hindle full setup. jet kit. so its not stock. dyno at 123 horsepower. that is really pushing a 600. i have a 2001 rr 929. hindle full, powercomander. dyno at 150 horsepower. that is just way to much of a gap. then we look at the weight. mine i think is about 40 pounds more. it just dosent add up.
im not saying that you are or are not a good rider or the other guy is or is not, we are just talking about bikes. i ride with alot of 600 and 750s and at times when the trash talking gets a bit harsh on the chatterboxs my buddy on his r1 and myself can just about leave them in the dust at any given time and for about as long a time as we want. not to be a prick but 600s just dont have the power of a 1000. they are very fast i will say that but when i see my buddies down shifting to 3rd while i just twist, i dont know, lets just keep it real

IM ONE OF THE 600 FANS , I LOOK AT THE POST AND THINK ITS POSSIBLE . IM 130LBS OK, ON A 600. LETS SAY ITS A 180 GUY ON THE R1. WITH A FEW MODS I CAN TAKE A R1 . THE POWER TO WEIGHT RATIO WILL BE IN MY FAVOR WITH A COUPLE MODS. I THINK. I RACED A OLD KZ 1000 GOT HIM. ITS NO R1 BUT I GOT HIM GOOD. HERES A COUPLE SITES ONE OF THE R1 AND THE F4 WHICH I OWN. THEY HAVE 11.049 FOR THE F4, AND 10.16 FOR THE R1. GRANTED THERE BOTH OLDER BIKES BUT ALL BIKES HAVE IMPROVED IN EVERY CLASS. TOP END THERES NO WAY. HE'LL LEAVE U GETTING THERE. BUT FOR THE 1/4 MILE I THINK WITH A FEW MODS ON A GOOD 600 "I" COULD. BEINGS IM LITE. WITH MY STOCK BIKE I BEATEN NEWER 600S . I KNOW THERES A LOT OF THINGS TO FACTOR IN , LIKE IF HE WAS A GOOD RIDER/RACER. BUT I THINK ITS POSSIBLE.

If you're lucky...you'll get him in the 1/4 mile. After that...try to get his license plate number before the first cop he flies past does.

I hate when people say "it can't be done." It can be done. Re-map the fuel injection, change the pipe. 150+ HP is very do-able out of
a 600. The thing is if your are looking for one thing, your probably not going top find it; but several little things will get you there. My advice though is ride within your skill level and get him in the twisties.

O.K. I bow to all the wise 600 engineers who are getting 150+ HP out of these lil beasts. I hope it's reliable HP cause it sux to break down while racing. The original question was what would have to be done to hang with an R1 in all aspects: 1/4 mile and top end. I'll give you the fact that it'd be a lot easier to keep up in the 1/4 mi than top end without major $$$ being spent. And I'm not sure a 600 would ever reliably stay with an R1 top end wise on all motor. Ya, I know, I keep up with my buddys R1 and I gotta friend whose 600 pushes 200 and bla bla bla.

So I'll end my postage on this subject with the only way I honestly know of that an F4i can keep up with an R1 ...
