'06 GSXR-1000's have stiction issues

I am having "issues" with my bike's front forks. I'm experiencing about 15mm of stiction on my front forks and it kind of ticks me off beings that I thought my bike had pretty proper suspension. It's hard to set my sag up front without a consistent reading to go off of. My fork pistons are coated with that Ti nitride (or whatever it's called) coating that is supposed to reduce friction. I don't exactly have the money for some Penske or Ohlins suspension... I'd like to make the best out of what I've got... and what I've got isn't cutting it right now on the track.

Has anybody else heard about this issue with the GSXR-1000's?

have you popped the caps off the forks to see how much friction there really is? 15mm is a lot and it could be that your forks are tweeked slightly. you can try loosening all the bolts on your front-end, then re-torque them. that can help realign things properly.

i don't follow or lead so stay the hell out of my way

I did that 4 times at my last trackday... using my front stand to keep it off the ground. I was trying to find a good balance with my geometry after adding a 190/60 series rear tire. I was moving my forks up and down the triple tree to find what would work better. I was having all sorts of headshake down the straights and one of them almost kicked my ass. I went into a violent tankslapper after passing through 120 mph... I somehow kept it from crashing and slamming me into a guardrail along the left of the straight. It wigged two riders that were following me the F-out and they had to pull off into the pits and call it a day. Needless to say, I'm having high speed stability issues that must be resolved asap.

A suspension guy I visited was bad mouthing the stock GSXR-1000 K6 forks. He hadn't seen stiction like that in a while. I guess I need to go over things and double check everything again... the bike has never been down.

I have the same coating on my forks and there's very little stiction. Could yours have gotten tweaked somehow?

The suspension guy I talked to said that the 750 forks work better... WTF? We actually talked about this topic for a minute or two. I don't know... Casper must have been pushing on my front wheel when I was tightening things back up or something. I don't know what's going on.

I just though of something. I hauled the bike across the country on a trailer from Southern Cali to North Carolina. The suspension may have been compressed for too long of a time (or it was compressed too much for the trip) and it may have attributed to some sort of damage that is hard to detect. Do you guys think this is a possibility?

Stiction is caused by fork components binding due to insuficient clearance. I would take the forks off and take out the spring and dampner cartrige. Then move the fork up and down. If stiction is present it will be obvious. Remove seals from fork. Move fork up and down. If it still sticks then your bushings are too tight. Replace the components that make the forks stick. The coating on the tubes is a non stick coating and should not contribute to the stiction problem. You may want to rub some oil on the fork tubes to lubricate the seals. Sometimes it helps as the seals get dry.

Thanks a lot Veefer. I'll get some more fork oil and give it a try. I'll probably order some racetech bits anyways and improve on them. I know for a fact that my springs aren't stiff enough for me and doing the ol preload trick doesn't even cut it. I keep bottoming out the damn things and I only weigh 170 lbs with full gear on.


Damn, trackday bikes are becoming just as much of a money pit as modding my Evo and WRX can be... well I sold the Evo because it was the devil. It was the black hole for all that was cop and ricer like. (the Jap engineers must have put a hidden tractor beam on it)

I'm on a govt work computer right now. I'll have to post some pics when I get home. It was a white Evo IX with the Vishnu v400 package (406bhp on 93 octane). It was so much fun. I'm anticipating the Evo X and then I may pull the trigger on that one. I have one vid on youtube. Search for "Evo IX dirt" and you'll see me having fun in the dirt.
Here's a couple I found on the web. Some cameraman took these. Can you guess where I'm at???http://www.allfortheride.com/gallery...111312530-L-LB

My fork springs on my '04 were also too light for me. And, I have a modded WRX money pit.
