Title: Steering Stabilizer??
Post by: chefod on October 08, 2005, 09:41:34 PM
Anyone ever hear of a steering damper for a GS500F , mine gets a little hairy around a buck 90!

any bike might get a little unstable around a buck 90.

Do a search for more specific information, but no company makes one for the GSF. You can rig one up by mounting it to the forks and the frame, but you need to fabricate stuff.

Like I said, do a search for more specific information.

I was about to laugh at your post until I realized you probably mean in KPH. I know the GS  can't do 190MPH.

190kmp=118.75 mph.  Source my romainian coworker.

118.06 mph, really... Thanks to Google for that one.

Damn close though.

still even at if it was kmp it would be tough to get it to that speed without some mods and of course it is going to shake

Oh yeah. Mine gets to shaking a little bit around an indicated 100mph

I dont know if its because I have TAG metal dirt bike bars on mine but i've topped it out plenty of times and almost never gotten wobbles or unstability... unless I cause it by riding in a groove in the road or streamlining a semi and even then its not even severe enough to warrent any action other than holding on.

Try switching the suspension.  |Changin out the fork springs and possibly add some good emulators.    It might be that the bike is way too undersprung for that speed.    

Also make sure that you arent gripping the handle bars too tight.  chances are you are moving the bars when you go over bumps and it isnt the bikes fault.

Hey I've got an idea slow down.

One of the better suggestions Ive heard

Yeah that took me a second. I think the only GS 500 that went 190mph was one that got pushed out of the back of a c-130 at 20,000 feet.

Post by: AgentNitz on October 10, 2005, 03:10:12 AM
someone dropped a gs out of a c-130?!  :? i was just wonderin tho... what's the terminal velocity for a gs? my brain doesn't wanna do math right now... hopin someone else'll be bored enough to answer that question =P and next time you hear of a gs being dropped out of anything, don't let em! gimme!  :mrgreen:
Title: how do i change the suspension
Post by: chefod on October 12, 2005, 05:21:05 PM
how do i change the suspension, i found the tighter i hold the bars and dig my feet in i can get an extra 10km/h to bring it up to 210 the last bar on my speedo, if anyone has any suggestion, let me know?

So you get more horsepower by holding tighter?

Post by: finmac on October 12, 2005, 05:27:40 PM
190kph - didn't realize the GS had it in it...I've heard 170 tops, stock.
Title: duh
Post by: chefod on October 12, 2005, 06:00:47 PM
no more horsepower, it stops the wobble and i can pin the throttle, and my bike has a g-unit, k&n filter, dynojet kit, wileyco racing cam, splitfire sparkplugs, and everything else i could do to it, soon to be a 15 tooth front sprocket!

your extremely likely to get into a tank slapper if your holding the bars really tight.  you should really not be puting any weight on them at all.  Your arms should be almost totally relaxed.

To change the for springs you have to remove the top of the fork tube.  youll need a 1/2"  ratchet to loosen them.  to get the springs stiffer you can either get new ones or make a longer spacer to compress it more.  You can use PVC or some metal tubing if you like.  and then you just screw it back down.  you cant adjust the damping very easily unless you buy some emulators.  A simpe fix would be to go to a higher weight fork oil.   Stock is #10 so a #15 or #20 would work.

the back all you can really do is tighten the coil or buy a nother shock.  Ive heard of people getting SV650 and GSXR600 shocks to fit.   I have a GSXR600 on my race bike but it came with it on so I dont know how easily it fit on.

Chefod, bringing some excitment back to the board!

Hey, if you look in Racers Corner, you may find info on steering stablizers.  Some are required for racing.  Many people have done this mod, but it may require some welding.

BTW, a 15t sproket will probably slow your bike down a bit.  No more 120 mph blasts down to the fishing shack.

He's speedo's just more out of whack than most.

I dont think it is the speedo that is out of wack.
Title: Steering Stabilizer??
Post by: spirit33 on October 13, 2005, 04:31:29 PM
I had my speedo read 190 kph once , but i believe it was probably more like 180-185.
thats with full magnum race exhaust system, k&n drop in filter, rejetting.
it was very unstable.
last night installed progressive fork springs & 15w fork oil. hit 165 kph on pretty crappy road and it was so smooth and silky. i love my new springs !!!

actually 190km/h would be around 170km/h... the spedometer is approx 10% high... so the faster you go, the more out of wack it is. I had it tested by a calibrated police radar.

I'm not convinced that the "unintentional radar calibration" method is that accurate (i.e., getting a ticket).  One of the last times I was tagged (in my car), the speed he gave me was significantly lower than the speed I was actually travelling.  :oops:  I was braking rather heavily, though.  He tagged me at 77, but moments before I was going well over 100.  While I may have gotten down to 77 before he got the gun on me, I find it a bit unlikely.  I also think it's unlikey that my speedo was that far off.  He may have given me a break...it was a bit of a bizarre situation.

Ok, you got me there :P

but actually, most 4 cylinder bikes can get tested accurately on a dyno. But ours are done with the front tire so I guess its out of the question... i've done it on the speedtraps too that say "your speed / Max speed".

Well if anyone wants to come out to my beat I will gladly radar test your speed for you. :mrgreen:
