Who likes the GPR stabilizer? How do you like slow speed handling with GPR vrs without the GPR. Please just share your experience or feelings over the GPR Thanks Mike | ||

did not like. could feel the 'stiction'. | ||

I have one on my XB12R and I love it, but bought one for the 1125r and could not stand it, road with it half a day, came home and took it off. I don't know why the huge difference, but it will never go back on my 1125. | ||

Does anyone have a GPR that likes it.. track or street use | ||

Man, I don't know about the other guys but I wouldn't be without mine. I just have it set on #6 (of possible 20)and no low-speed issue at all. My (high-bar) CR would start wagging the bars at 90 and by 130 was bad enough that I'd call it quits there. With the damper it's rock steady on up past 140. Some guys here will rant on about the Buells are perfectly stable and that any steering imperfections must be rider error, all I can say is I've been riding since 1968 and have owned over 70 different motorcycles and was a decent club racer in the '80's and never had any problems before. And I LOVE my CR. But it needs the damper. Mine does anyway. It's worth mentioning the 1190's have more rake and a damper, so...

i had a pretty severe tank slapper one day on my way home from work. it was my fault though. no stabilizer. ripping hard through first, second and third. once the front end came down most of the way through third gear, it was a little off center and started the headshake. i was kinda used to the headshake, but this kept getting worse. i relaxed as much as i could, loosening my grip, using my knees to grip the tank tighter. finally i said the hell with it, revved it up to pop the clutch so i could try and smooth out the landing. that was the worst encounter i've had with the steering on the cr. i came home and told my wife i was getting a gpr and she wasn't gonna stop me. she asked why, so i took her down the road to show her the black marks my front tire left in the road. needless to say, i absolutely love my gpr on the road. i also have mine set to 6 out of 20. it's still light enough to let me know when my steering inputs need to smooth out, but dampen the headshake i used to have. in my personal experience, i think it was worth every penny. and low speed stuff, like riding in parking lots seems to not be affected at all.  | ||

I called gpr about having the thing serviced, told them of my low speed @ 0 setting, ridability issue. The guy was very nice and told me they can put a thinner oil in the dampener which will give even less resistance @ the 0 setting. I am going to send this gpr v4 in for service and keep my fingers crossed. Thanks for the input.. Does anyone else have the lighter oil in their stabilizer? | ||

Al Lighton at American Sport Bike rebuilt his GPR with lighter oil for his track 1125R. He said he needed it. I trust his judgement. | ||
| 1125rcya |
Id like to know what weight he used, so I could recommend the proper weight when sending my gpr in! | ||
| Dhays1775 |
Shoot him an email or give them a call. Al and Joanne are two of the coolest Buell people I know. They won't steer you wrong. | ||
| Duphuckincati |
"steer you wrong". Funny. | ||
| Jdugger |
> Al Lighton at American Sport Bike rebuilt > his GPR with lighter oil for his track 1125R I agree. Even on the lightest setting, the bike I rode with one was like fighting the steering and it caused the whole front end to push the front tire on corner entry. Plain dangerous if you ask me. Bike was safer without one at all. | ||

A little bit of a correction on this.... I currently have it the GPR OFF my track bike. I'm still doing setup with it since changing several suspension components, and in it's current form, the GPR is not helping, it's hurting. But that's largely because I don't have my track bike set up right yet, AT ALL. I don't have enough front end sag, and my rear ride height is too short even though the rear sag is right. Those two things are conspiring to make the bike turn in way too slowly, and the damper isn't needed and would just mask the setup feedback. I need to do some fork surgery before I'll get it even close to where the damper is needed. Progress is slow when you only do 4-5 track days a year, and slower now that I have to put it all back together after the dork that put me down at the last track day.... But that said, once it is much closer to set up right, the damper will go back on. A damper should be virtually unnecessary for a perfectly set-up bike, but can be good insurance when it is close to being perfect, or perhaps on the other side of that from where my track bike is now. But that implies that in it's lowest setting, it should be doing virtually nothing. And it was way too stiff at the zero setting as it came from GPR. I changed the fluid to some 2.5-5 weight and got the damper so that it had less effect at 0 than it did as it came from GPR. For now, it stays off until I get the bike dialed in better, but it'll go back on once I do. I have one on my street 1125R though. It's fine there, but I do plan to change the fluid on that one as well. I'd like 0 to mean closer to 0 on that bike too. One of our local customers totalled his 1125CR on a freeway tank slapper. A damper would have saved his bike. My guess is that his bike wasn't perfectly set up either, and was probably too far the other way from my track bike. But until/unless you're an excellent suspension tuner, a damper, GPR or otherwise, can be some nice insurance. Al | ||

Thats the same feeling I have }JDUGGER. I noticed that the lighter the torque on the hex bolts, the less feedback I received from the gpr. I'd rather have nothing than this control freak (gpr).} | ||

You need to be careful with the settings. It is easy to adjust it higher, and get used to it. Take it off, and it feels too 'loose'. I have mine set on a lower setting now. Jim, the weird feeling I was having in the front end went away when I serviced the forks and replaced a notchy front wheel bearing. I appreciate your opinion 100%. You are a more skilled rider than I am any day. It just scared me when the front end wobbled at high speed. That's why I got the damper. I understand it MIGHT have been rider input on my part that caused my wobbles, but I still want to do whatever I can to prevent it. I have not had a wobble since I got the damper. You going with us to Arkansas? | ||
| 1125rcya |
Thank you Al for your feedback on the gpr. All I want is a little security for the times the front wheel comes off the ground in 3rd not expecting this, and give to much feed back causing a quick light wobble! I am really wanting a blanket just in case of my poor judgment at that given moment.  rider error 101. I think your on to something with this lighter oil Al. Thanks guys} | ||

My tank slapper days with my 96S1 had more to do with having enough rear preload to keep the front end down at speed. | ||
| Al_lighton |
BTW, it wasn't hard at all to change the oil in the GPR. A couple screws on the bottom, a big syringe, and a little bit of patience was all there was to it. I found the instructions for it on some Gixxer forum, google around, you'll find it. Al | ||

I don't even notice mine anymore on my CR. But feel alot better knowing its there even if I never hit a situation where it would make a difference. Mines set for 12. | ||
| Jdugger |
> You going with us to Arkansas? Not sure I'll have a bike. A guy really wants my CR, and I've ridden it twice since I bought it from Kevin, both times at the track. So, I'll probably sell it Saturday. | ||

Interesting. At 0 my GPR does absolutely nothing. I run it about at 9 and that works well for me. It does slow things down a bit in the real tight stuff, but the thing steers a bit quick for my tastes anyways. My bike is set up ok. Certainly not track tuned, just street use. I installed it because I had a huge tank slapper at near triple digits shook so bad the front pads came off the rotors and it took a couple squeezes after it settled down to reel it in entering a sharp left hander. Yikes! Turned out my rear shock blew somewhere between the start of my ride that day and the slapper. Throttle and relaxing didn't stop it, so I pushed my hands into it as a last resort before bailing off and that worked. I'll never own a bike without a damper again. | ||
| Bigblock |
Hmm, come to think of it, I've been riding some real tight twistys the last couple days and it has felt a bit slow turning. Must need to dial back that thing to 5 or 6. Thanks guys! | ||

I would really like to get some kind of stabilizer for the 130+ head shake and when the front tire comes off the ground. It's hard to justify spending $400+ on the GPR unit. I wish there was a way to stabilize it without having something mounted to the top triple or having a damper sticking out and mounted to the fork tube with an ugly bracket. | ||
| Stevek1125r |
I found that when i had my rear suspenion set without enough preload, the front could get erratic. Now i'm not a perfect rider, but once i added more rear preload the bike was alot more stable... all the way up to 160+mph.... I have a Gpr Damper, because i have had a scary moment when getting into too much throttle on a bumpy/curved road.. the tank slapper only lasted a few heart beats, but it was enough for me... I do agree the gpr unit is stiff and i only run it at 1 on the settings, and since then i have never looked back.. ride a wheelie, do high speed runs and have seen no trace of a tank slapper... thats good enought for me... For me it was 400.00 worth of added insurance. | ||

I guess because I'm a well built (muscle) big man I keep mine on 9 and am happy with it there. It's a bit stiff, but I don't find that a bad thing. If I have to do tight precise parking lot maneuvers then I turn it down to 0-1. | ||
| Mackja |
This thread got me thinking again about my stabilizer, so today I contacted GPR and shared with them how the one on my XB12 is perfect and how the one on the 1125 was awful, they are sending me a new one at no charge, so I will update my findings as soon as I get it mounted and tested. | ||
| 1125rcya |
Mackja Glad to hear they are taking care of you. Let us know if the feeling of your new GPR is any different than the old one. I sent mine off today for service, it should be there Friday! I was told it is about a two day turn around. I hope their right, the 22nd I have a track day. My first experience with the heavy oil GPR seemed as if the front tire dove into the corner a little faster and deeper. I'm not convinced that the feeling is all in my head. If and how does the GPR change the feeling of your bike on a heavier setting. | ||

I love mine on my CR. After a tank slapper deep into 5th gear without it coming over a rise I find it dangerous without it. Haven't tracked with it but have had my knee down with and helped a lot. My buddy has one on his R that he likes too. | ||
| Laylo |
I've finally found the solution to my GPR v4 "sticking" then sharp release when trying to turn, also had the hunting issue..I've tried lighter oil (5w) but still stuck so to solve the sticking I added a washer on each bolt between the GPR unit and base bracket. this took the pressure off arm that connects to the tank and eliminated the sticking. Seems to work great now |
