Engine upgrades...
Hey, I guess this is the right place to post this.
I have a cbr600f2 engine that I am planning on putting in a streetfighter I am currently designing, and I'm at the stage where I want to start getting it ready for the bike. I was just wondering if someone could point me in the right direction as to the more streetable mods that will give me reasonable power gain without compromising driveability. I mean anything, such as clutches, pistons, cams, what will be the best bang for the buck. I'm looking to have a bike that has comparable numbers to a more modern bike. Oh, and I will be fuel injecting it already, with an aftermarket can on somewhat shortened headers.
Thanks
As a matter of fact, what are the numbers of the stock engine?

RE: Engine upgrades...
well im not sure what to tell you about engine internals. but remember his the original f2 was 447lbs only 2 lbs more than the 03 600 rr when it came out. it had 87 hp 42 lb ft. i have a 96 f3 street fighter. it has a stage 3 jet kit, k&n, m4 exhaust, vortex 520 conversion with 1 down up front, factory ignition advancer adv 3 degrees, and all the work and dyno tuning was done by full spectrum racing in orlando florida. the dyno run was 109 to the rear wheels. now i bought the bike used so im not surewhat might have been done internally but this is a strong motor. the bike weighed in at 423 full of fluids so its about 8 lbs lighter than an 06 600 rr.the fuel injection your putting on should be good for atleast 3 hp with out any other mods. ive been looking all day for piston and cam kits for my f3 and havent found much. but heres a spec listing for mostbikes 97 and newer just to give you examples.

RE: Engine upgrades...
Thanks man, that gives me a starting point for sure. I'm hoping that with my weight advantage the horsepower difference wont be a hell of a lot, even with very mild mods. And the tec II i've got for engine management should add a bit like you said. Hopefully I can find a dyno on the rock one of these days.
Have you tried looking at APE Performance? They have a lot of different stuff, from street to track for a lot of bikes, i think i saw some F3 stuff there. Good guys to deal with too, know that from my vintage kawi days.

RE: Engine upgrades...
Yeah, they're pretty wicked, I'm prolly gonna end up just replacing all my gaskets, clutch pack and springs, getting a manual tensioner for reliability, and maybe get a head job(lol). ECU should take care of the rest.
Glad to help, APE actually has a forum on here, funny you didn't know about them. CBR Zone down in the sponsor forums is their spot.
