Top 20 FAQs For This Topic

	My FI light shines when I installed your pipe on my 2008 Hayabusa. What do I do with the O2 Sensor?
	Do you have a gear ratio calculator? Calculate your gear ratios
	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 have a 2005 Hayabusa with your clutch mod. For some reason the clutches don't last long. What could be the problem?
	I have a street megaphone on a Hayabusa with small box mod, stock filter, PC3USB, 87 pump gas? I have a flat spot with hesitation from 2500 to about 3300. Which map do you recommend for it? Don't want it to run too lean.
	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?
	A fellow Hayabusa rider forwarded me the Airbox mod procedure. I don't have a Power Commander yet but wanted to know if this modification would improve my mileage and horsepower. I have OEM air filter and Yoshimura Bling 22 4-into-2 exhaust.
	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).
	What is the best oil and weight to run in my 1397 Hayabusa.
	Dyno Testing with a Sidewinder--baffle in or baffle Out?
	Does my Hayabusa drop-in piston modified engine need a better map than the standard one you sent?
	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?
	Regardless of the style/type of lowering links you offer, do I need to additionally purchase a shortened kickstand? I'm looking at the adjustable models for racing - will the stock kickstand still support the bike if I have dropped the rear?
	When using the Brock's Performance Clutch Cushion Kit in my Hayabusa, what year OEM replacement clutch should I purchase?
	What is the highest compression ratio you guys have run milling of head to achieve it and what power gains for the Busa? (JE Flat Tops). What are the tightest piston to valve numbers you would be game to run? I will certainly be rechecking my MAC numbers when I take the lid off, my initial measurements were taken perpendicular to the pin with a .037 and .036 so I guess that averages to .0365?
	If I use a lockup clutch, can I use a cushion kit? How do I know if I need new clutch components?
	I just bought a Billet Cam Chain Tensioner and I was wondering if you had the spec on how to put the right amount of tension on the chain or how to set it up?
	I have a Streetsmart 3 system with PC/USB for my Hayabusa. The rev limiter seems to kick in at 9500 and then the FI light flashes. I checked the trouble codes and get 32-35 which correspond to injector malfunction in all 4 cylinders, but the bike is running great. Any idea on what's going on?
	I am looking at your "Top End engine package" or the "piston kit with cams" for my Hayabusa. Assuming that these packages increase compression ratio, what octane fuel is needed to assure reliable operation? The best fuel I have around here is 90 octane at the pump.
	I'm degreeing in two intake cams on my Busa and I would like to know what lobe centers to put them on. The motor is fairly stock with a Yosh header, 4-2-1 style with an exteneded arm, set up for 4 gears in a 1/4 mile and I weigh 220. Also, it has a Dyno Jet Power Commander and has been dyno tuned 159 H.P.
