Why has my FI light started coming on when the bike is decelerating? I cut the wires at the pressure switch for the clutch (so I could start the bike without pulling the clutch in).
I replaced the K&N air filter with the stock air filter and ran redline fuel injector cleaner thru the system. New result is 157.87 hp @ 92.61 ft/lbs. (higher ambient temp /lower humidity) When I changed the filter, the idle dropped, and I had to adjust the idle up to keep it running. I would think this is more restriction? The dyno shows the bike is now running richer than with the K&N filter, but producing more power?? People have suggested dyno tuning the bike, I wanted to get yor input before doing this.

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.
Am I eligible for map support if I purchased my Brock's Performance exhaust system USED?
How do I interpret the map names/abbreviations?
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.
Will I lose the map in my Power Commander if I unhook my battery?
Lose my PC map
If you replace your stock pipe with an aftermarket pipe, would a power commander be necessary?

How do I obtain map support for a USED Brock's Performance exhaust system?
I have a 2006 Gsxr1000, today I tried to start my bike and the only thing it did was turn over. I checked my gas tank it was low on fuel so I put some fuel in it, but it still wouldn’t start. I checked the fuses and the battery and there was nothing wrong with them. Could the spark plugs be fouled?
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?

I have an 06 GSXR 1000 with the clutch mod, all 6 yellow HD springs, and I have a .050 washer behind each spring. My gearing is a 16/43. The clutches hold the power (170mph plus in testing last weekend) but I’m having trouble launching the bike. I have heard that I have too much spring pressure, but if I take the washers out from behind my springs the clutches slip in high gears. I have also heard to try putting stock gearing on the bike and leave at a really high rpm so that the clutches have to slip on the low end but they will catch up and grab about 60ft out. The bike is 64" and I weigh 165.
I originally thought when I installed the TRE, on my Suzuki Hayabusa, the mapping was changing when you shift through the gears but I believe the mapping isn't changing, it's just shutting down the fuel pump in 6th gear. Is my theory correct?

What is the clutch stack height for an 01-04 GSX-R1000 when I remove a plate to make 8 steels and 8 fibers? I installed a clutch cushion for the back dated clutch on my 06 and have some OEM thick, thin steels, and fibers.
I have a drag bike with all of your stuff on it and a Sidewinder. Where is the best shift point on this bike in rpm for best ET?
Do I need to remove the flies on my 2008-09 ZX-14 for maximum performance? I read on the Internet that the flies are opened at the same rate as adding a TRE 008 to the earlier model ZX 14's, so there is no reason to bother removing the flies?
I have a '07 ZX14 and I'm considering your Street Meg pipe but have a few questions. 1)I already have a PC3 Power Commander and the secondary throttle plates out(map 011),what horsepower and torque gain can I expect after remapping with your pipe? 2)What is the cost including shipping to Edmonton,Ab.Canada including all fees? 3)Does a full system have an advantage over slip-ons other than weight saving?
I had a shop install a Streetmeg on my 2008 ZX14 and it started to leak lots of motor oil from the top of engine. What do you think went wrong with the install? Is it coming from the air box or valve cover gasket? Did they plug up the wrong port or hole.?
The Speedo Healer for my 2008 Hayabusa didn’t work around the stock speed limiter. The product is installed and working properly as far as I can tell. I can program in different % offsets and the speedo reacts like it should, but the bike ran 180MPH in 6th gear on the dyno and signed off.
Do you have or recommend a ZX-14 smog valve removal kit that helps my bike's performance? I have a full Brock system, Power Commander, BMC filter, and secondary plates removed.
ZX-14 Smog / Pair Valve Block Off
I have a 2008 Hayabusa with the following items; Power Commander with your supplied Map, Air Shifter, Brock’s Exhaust system. I'm running 9.4 the 1/4 of mile. Someone told me that the ignition module is necessary to run below the 9 seconds. Can you provide some advice?
I was reading on a forum where people are "claiming" that when they remove the baffle on their ZX-14s with the stock motor they loose low to mid range power and the bike won't launch hard. Have you experienced this problem when you test systems or are they leaving out details like not using correct map and other mods? Does removing the baffle require a different map?"
I have a Street Megaphone system on my 07' ZX-14. Does the Alien head offer any more horsepower? Any less? I like its design and would like to get it but I am not ready to give up performance.
Rear sprocket for a Hayabusa and want to know how many teeth should I go with that would not effect my top-end. I am down one in the front. The bike will be used for quarter mile 10% of the time and the rest will be road racing on the highways. I have your 1397 kit!
I own an '07 ZX14 with PCIIIUSB, Roaring Toyz low-exit megaphone exhaust, Pipercross air filter & a custom map by a local custom tuner. Not too happy with the results & other people & tuners have told me it's the pipe. A common recommendation is the Brock's ShortMeg. Is there or has there been any testing against these 2 exhausts. Any comments or advice would greatly be appreciated.

My 2007 Kawasaki ZX -14 bike is running absolutely great. Question -- Will it affect your fuel map in any way, if I change the front chain sprocket from a standard 17 tooth down to a 16 tooth sprocket, and leave the standard 41 tooth sprocket on the rear wheel?
Can I get 250 hp from my new BMW S1000RR when I race at the strip?
I have a 07 Hayabusa I’d like to wake up a bit, my last bike was a stock 05 GSX-R1000. I'd like to also think reliability as I've got a touring set up for it to take 5 and 6 hour trips. From suggestions I'm looking at the intake cam for exhaust, your Gen3 pipe, Power Commander. And local guy mentioned removing a gasket that would bump the compression a half or so. ? got me... he is reputable wrench/builder though. Does any of this sound as good reliable set up for my 07 Hayabusa?
If I have a Yahoo e-mail account, can this cause delivery problems or delays in receiving my maps?
I've been using the map that was sent to me and I checked my plugs and it appears that I'm running on the lean side of things. There's some detonation going on and it's causing the plugs to loosen. I'm running 93 octane pump, should I switch to 100 octane?

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 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'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.
When using the Brock's Performance Clutch Cushion Kit in my Hayabusa, what year OEM replacement clutch should I purchase?
Can you use the KTRC (traction control) on the ZX-14R and/or ZX-10R even if you attach a Power Commander V (PCV)?

My bike runs horribly, is it the map?
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?
I've followed your progress on the 2012 ZX-14R. The ECU mod put up great numbers, so why use a Power Commander? The ECU mod removed the top speed limiter and still provides a great a/f ratio from the Dyno sheets I have seen.
Is there a general rule of thumb for gearing when adding more length to the wheel-base?
