Re: Fork setups...Enough already!!!

Length of fork, from stem bolt to the center of the axle while on the front wheel is also a factor. If you're on a f4i front end and it fully compresses, it could be really short and account for the nasty tank slappers. A 954 front might not compress much compared to the f4i, thus giving it the added stability. There are several factors, initial rake/trail/fork length and the length of the fork compressed while it is on the front wheel supporting all the weight. Once these are determined, there is no reason the stock forks wouldn't give the same feel as the inverted setups. If a f4i's forks are a full 2 inches shorter than a 954 while on the front wheel, it would explain the super-aggressive front geometry and the lack of overall stability.

Same spring rates. Same rake/trail. Same fork length. I think this is a job for Race Tech. This needs to be settled once and for all. Swapping out the front end doesn't affect the weight balance of the bike. The motor is still in the same place, etc. It's all to do with the goemetry of the front end that enables it to hook up better, and the spring rates give it the sturdy feel. There is nothing so far that leads me to believe that it can't be replicated with the stockers.
if you put an f4i with a 954 front end on it next to a stock f4i, the one with the 954 front end will sit higher in the front....it makes them higher/taller in the front, so you have to lower them about 1-2inches in the front.....

Re: Fork setups...Enough already!!!

I've rode quite a few diff bikes. And just bought a F4i with a 929 front end on it last month. Im not king kong stoppie man, but i've notice just from hard accel to braking when i first jumped on it it wanted to buck me up into a stoppie. Might be the way the fork is setup to the bikes center of gravity. but **** what do i know

Re: Fork setups...Enough already!!!

I took my front end (Stock F4i) ran 1.0 Race tech springs, 15 weight oil (2 steps heavier), had a certified suspension tech guy revalve the forks for a slower rebound to reduce pogo, and I dropped the forks down in the triples a bit. My front end feels great right now, Real smooth and solid without pogo-ing. The Stock lower triple could be less flexy, but whateva... I like my setup now.

That would explain why it's more stable. So, what I'm seeing is the stock front end sags too much and the tubes compress into the forks causing a much more radical front end than the 954 setup. Plus, it's mushy and that would explain the pogo and tankslaps.

stock gixxer 600's felt different from my old 1000 but i could still hit 800, my big thing was allways using 2 steering dampers

more of a head game i think

most of us can't afford two dampers

Johnny seals had two for awhile I think.....and he had to handmake the bracket to put the one on the from of the forks!

Neither the 600RR I already have, nor the 1000RR I'm wanting to get have set-ups already made to be able to mount dampers to the front of the forks and only to the top of the triple clamps!

i think ill pass.. im not going to cake myself for that one... now are we talking stock clipons here on the f4i.. cause db bars dont count in this discussion.. the reason is they give you added stability in stoppies ... so stock like i said f4i sux... put db bars on and you totally eliminate the chance for tank slappers...
matt i think there are many problems with the stock f4i front end... clipon position head tube and triple rake width of the triples and bars and the forks are complete garbage..and the brakes and front master cylinder are a joke.. the f4i isnt even a good bike for stoppies even with a 929 front end...

Re: Fork setups...Enough already!!!

now another questions (and this was touched on by teach)... i ride an 04 600rr now (non-radial) and the difference between my old F4 and this is night and day. i think its mostly to do with the brakes being better but i just bearly touch the thing and its at balance.

and to what cramer said, i was trying em without a damper and then i went out and bought one, and i dont notice a difference at all. now, i dont have the steering stopper gpr, but i do have one.

all in all, i think it all comes down to how quickly you can get it to balance and the motion it takes traveling there. also, body position is HUGE. my stoppies have been gettin better lately and it is all because of body position (locking your arms, head up, that type of ****)...

smae with lower clips-ons, the more weight you put over the front, the less likely to lock-up.
Ever wonder why Schwartz likes my F4i for stoppies over other identical F4i's?
