how do i make my 98 600 f3 faster

[carterman]

Besides a jet kit which i am getting done soon and different sprockets, what else can i do to my bike to make it faster, im getting 96 hp to the wheel and would like to raise that to about 110 t0 120 hp at wheel?

you're talking about 15-20% power increase - It's not going to be through boltons.

Race cams, Wiseco big bore 637 kit maybe? Something along those lines....

96hp is already a fairly strong F3. I wouldn't bother with a jet kit unless you already have a full exhaust system and cams. If you want 120hp though I think you're going to need flatslide carbs as well and probably bore it 2mm. You're basically trying to make your '98 600F put out similar power to the '98 900RR but with only 65% of the engine capacity - not going to be easy or cheap.

Drawbacks of the F3 are the weight (10% heavier than the F4) and crap brakes, so I'd fit some proper calipers and floating discs, and then remove as much excess weight as possible. I think they even have a steel swingarm don't they?

you get a 2003 plus 600rr

[Rendell]

get a 2003 + 1000rr. then if you need more you will be breaking into the engine. I personally do not see the need for that much more HP, unless you weigh 400 Lbs. I believe that is outside max weight cap. anyway.

This is the first bike i have ever owned so i dont know what it has on it.Is there anything i can do to make it quicker rather than faster through bolt-on parts, and also what can i eliminate to make it a few pounds lighter

How is that going to make his F3 any quicker though....

If you want it to _feel_ quicker and more alive drop a tooth off the front sprocket and add a couple at the rear.
Full exhaust system, cams, flatslide carbs are all bolt-on items that increase peak output at the expense of civility at road speeds.
Your '98 600cc 100hp engine weighs 62kg - the same as modern 170+hp, 1000cc engines. The F4i engine weighs 59kg so it could be well worth swapping the engine in along with the complete fuel injection and electrics. The 600RR engine is marginally lighter still, revs faster and makes a bit more power, but is not the same engine design so would require more fabrication to swap. There are also F3's around with 900RR engines in them already.

To reduce weight and improve performance:
Lightweight full titanium race exhaust system.
Replace all the plastics with lightweight race fairings, smaller headlight and LED rear lights and indicators.
Remove the pillion seat and pegs and run a race tail unit.
Cut down/remove/replace the battery tray and rear guard.
Remove chain guard.
I think stock is 525(?) so switch to lightweight, race-quality 520 chain and sprockets.
Lightweight pegs and rearsets.
You can also cut off the entire steel subframe and fabricate an aluminium one for the rider only. This would probably make the frame illegal though (here you aren't allowed to cut or weld the main frame).
Remove the bar end weights.
Modern OEM forks, clamps and shock, revalve yours, or buy aftermarket suspension.
Modern calipers and master cylinders (no need for radial-mount though, conventional axial-mounts work just as well and are often lighter). Late GSXR600 conventional forks and brakes are a great addition to any older bike.
Modern floating front discs. Make an aluminium rear disc.
Replace the steel swingarm with a modern aluminium one.
Lighter modern OEM or aftermarket magnesium wheels. Don't bother with aftermarket aluminium wheels as they're often heavier than the OEM's.
Carbon fibre airbox.
Aluminium fuel tank.
Lightweight race battery.
If you're doing track work, removing the entire starting and charging systems make an enormous difference.

Silly question, but since this is your first bike.. Where do you ride that thing?? Bellow or above 10 000 rpm???

[carterman]

i mainly ride it on the street so under 10000 rpm but i wanna start going to Road Atlanta cause around here nobody watches for bikes. but i got some money to put in my bike so i would like to get it a little quicker or something

[Melt-Down]

Ok, well, this is the thing, NO 600cc bike will move bellow that magic 10 000rpm mark. Just try that for a while.. Get 2 even 3 gear lower then where you would usually be. If then you still think the bike is not moving enought for you, then yes start playing with the engin performance.

Very good point.
The easiest and cheapest way to go faster is to simply learn to ride the bike. You'll find guys on 30hp 250's running rings around you regardless of how much power you can make out of the bike until you learn to ride it with the power it has now.

[carterman]

cool that helps alot cause the bike seems to have all its power between 8 and 12000 rpm. plus im only 140 pounds so im hoping i wont have to put too much into the bike to make it a little quicker. Bladeracer put down some pretty good tips too but i dont know if i will go that far into lightening it

[carterman]

yea ive been trying to choose wisely where i try to haul ass and corner fast cause like i said nobody watches for bikes and my uncle got killed on his, and i mean im not really scared of it im just trying to respect it, i wanna go to road atlanta just for fun but i definetly think i need to ride some more before i do that so i dont hurt myself or anyone else out there on the track

[carterman]

is there any other seat and rear fairing for the 98 cause i would much rather have the separate back seat so i can put a seat cowl on there, i think that style looks much better
