I have a 2005 Hayabusa with your clutch mod. For some reason the clutches don't last long. What could be the problem?
My Suzuki GSX-R1000 (Or Hayabusa) misses and stalls abruptly when I pull the clutch lever in – Do I need a Map? Is my Power Commander bad?
How much power does your clutch cushion kit hold up to for the GSXR1000s and Busas? I have been using a lock up and have had nothing but problems.
I installed your ultra clutch mod and yellow springs. Now, when I am on the line can I just dump it (does it drag or slip by itself and then bite) or do I still have to drag it? Is there more than one way of setting the clutch? I saw something about washers behind the springs? I am running 14-46 gearing and trying to keep the front end down through the end of first. I have a GSX-R1000 that's lowered and strapped with weights.
Clutch mod and HD springs: I have both in my Suzuki GSXR 1000 05". What I need help with is the clutch adjustment after both are installed. I see there are 3 adjustment areas; 1) the lever 2) the clutch release adjuster cap 3) and the clutch cable adjuster under the tank. How should all three be adjusted for the correct setting? Here is what I've noticed, when I leave free play at the lever it's hard to engage the gears but when it's tight at the lever it's no problem. I've followed your instructions to the tee and still it boggles me. I guess I don't know what I should expect with having your mods in there. Also where should the clutch start to grab? Very soon from the handle or in the middle? This has been racking my brain since I've owned the bike.
What is clutch creep, what causes it?
2002 Hayabusa 1397. I have your piston kit, intake cam, exhaust cam, sidewinder. Also PC III USB, 10 inch over swingarm, 60hp shot wet nitrous. It has no air filter(block-off plate) and used as a track bike only. 1. What type of fuel do you rec? 2. Do you have a map available? 3. Should I run baffle or not? 4. What be proper gearing, I weigh 200 lbs? 5. I have a MRE lock-up, should I run your spring package as a baseline? 6. How much can you safely spray until you have to take timing out?
If I use a lockup clutch, can I use a cushion kit? How do I know if I need new clutch components?
I have installed the Ultra Clutch Mod, and at first it seemed like the clutch was engaging at the half way point of clutch lever, but after a couple of hard launches it seems to be engaging more towards the almost full out. How do I set the clutch at the adjuster and know its right?
I have a 2007 gsxr 1000, Brock's clutch mod I have 2 clutch cushions, am I supposed to use them or just hyperplate? I have to let the clutch lever about half way out with no slipping and I would like to have it closer.
I've ordered and installed your clutch cushion mod for the 01-04 GSX-R1000. Would it defeat the purpose if I put the cushion in but left the stock springs in? With all 5 of the HD springs in the clutch lever it is very difficult to pull in, especially in traffic. Im not that big of a guy, at only 130lbs fully suited.
I have a 2006 GSX-R1000 and it has the 04 clutch (5 springs) with the stiff blue springs in it. Can I purchase the yellow 05/06 springs and put them in to make the clutch lever softer, because the blue ones are very stiff. Just want to know if it fits before I order them.
I run a GSX-R1000 K3 with one of your clutch cushion kits. My question is, can the cushion kit handle a 40 dry shot of nitrous?
I just bought a clutch cushion kit for my 93 Katana 1100. In the directions it shows using a lock up clutch. Do I need to run a lock up?
I just put an Ultra Clutch Mod in a 08 GSX-R1000. The lever releases too close to the bar. It rides like a dirt bike, two fingers on bar, two on lever. What can I do to make it release further out?
Is the Ultra Light Clutch Mod for the 2008 GSX-R1000 the same as the Clutch Cushion Mod?

What should clutch stack height be with your clutch cushion kit installed in a Gen 1 Busa?
I am installing your Ultra Light Billet Clutch Mod for my Busa. I can remove the nut from the hub assembly with an impact gun, but I do not feel comfortable using it to install the nut. I would like to torque this to the manufacturer spec. Where can I find the tool illustrated (the Clutch Hub Holder) that is shown on your instruction paper?

Hi I purchased your Clutch spring spacer kit for 2004-2007 zx10r and they do not seat into the "retainer" or "bucket" on top of the springs, way undersized. I tried a 2004 and 2005 clutch. Could it be packaged wrong, or what am I doing wrong here cause it doesn't make sense.
My H2 makes a squeak noise sometimes. Some mechanics recommended that i do not use the kawasaki 10w-40 synthetic oil, because it shortens the clutch life. Is this squeak normal? And could it be from the oil or heavy duty springs I installed?
