Top 100 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 have a 2005 Hayabusa with your clutch mod. For some reason the clutches don't last long. What could be the problem?
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.
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 have the air box mod instructions for my GEN 1 Hayabusa. I don't have a Power Commander, 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.
Dyno Testing with a Sidewinder--baffle in or baffle Out?
What is the best oil and weight to run in my 1397 Hayabusa.
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?
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.
Will an intake cam on the exhaust side work with my slip on GP style short pipes on my 09 Hayausa? Or do I need to change the whole exhaust system for it to work?
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 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?
Does my Hayabusa drop-in piston modified engine need a better map than the standard one you sent?
If I use a lockup clutch, can I use a cushion kit? How do I know if I need new clutch components?
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?
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?
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?
Why don't you provide Ignition Mapping for your exhaust systems?
How do I keep my 2008 Hayabusa with a 6 inch swing arm conversion from spinning the 210/50 17 rear tire at 6,000 rpm or from the blocks? I am in South Africa.
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 thought I might have an exhaust leak around the header flanges, so I took my bike (08 Busa) to the dealership and had the exhaust gaskets replaced. The sound is still there and they say it is common with aftermarket exhausts. Is this the case?
1) Could you please advise me what is the advantage to using; the Cam Pin for 2008-2009 Hayabusa 2) I have a 5mm offset stroker crank (Muzzys) & 86mm bore offset big block. What is involved in fitting this 2004 crank in 2008 motor? 3) Will a 2008 busa throttle body fit a 2004 motor? 4) Either way, I'm planning on sending my 2004 head to you guys for the Street Chaos job & purchasing a set of Street Chaos cams as motor will be 1580cc.
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.
I have a new 08 Hayabusa and added the following; Alien Head Exhaust, Power Commander USB III (Brock’s Track map), O2 sensor jumper, Cycle-Tek airshifter. A few days ago when I was using my airshifter I the FI light started flashing. When I shut the bike off it won’t start and when I wait for 10 minutes it starts. I also ordered a new Power Commander, to see if my current one is the issue.
What clutch spring setup would be good for my high horsepower Hayabusa and how much can it handle?
Brock's, Please advise, I own an 2005 Busa 1394cc with a MTC Multi-stage Lock-Up, a MTC billet clutch basket and MTC inner hub. I want to stop using my lock-up and switch to your Clutch Cushion Kit instead; however, I want to keep using my MTC basket and inner hub. (Note that I have already purchased your clutch cushion kit #270500 and clutch spring spacer kit .280 thick #270435.) My question is, do I use your Clutch Cushion Kit HD and XHD springs and your Clutch Spring Spacer Kit .280 Thick together with my MTC hub and basket? I ask because I read Dragbike's March 21, 2003 "BDE Hayabusa Clutch Cushion System" article which mentions to use your "S13-CCK-MTC" with MTC lock-up unit. I am guessing that the nomenclature, "S13-CCK-MTC" is now your Clutch Spring Spacer Kit #270435; is this correct? Additionally, I read in the overview section of your Clutch Spring Spacer Kit .280 Thick, that it too mentions using with a MTC Inner Hub. Thanks much for any advise provided.
I was planning to set up my 08 Busa exactly how I had my 03 because I was so happy with its performance. Stock motor, your mods, street pipe, 6" over arm, 16 42 gearing, 40 hp dry kit =9.0s @154 1.50s 60' (I weigh 220 in shorts) but with the new 08 (stroke) I'm unsure??? Any advice would be GREAT!
We have a Hayabusa with a VHM 1500cc for Street and Track. We are using the stock injectors and ECU with a PC3USB. Is that correct?
I installed one of your maps into my bike, it runs fine if the throttle is wide open but I'm having flat spots at cruise speeds around 3000 3500 rpm and 5000 to 5500 rpm and my bike backfires when letting off the throttle.
Will a gen1 sidewinder fit on gen2 hayabusa?
I have a 2008 Suzuki Hayabusa with an Alien Head full system. I have noticed a sound coming from the front that sounds like an exhaust leak. I took the bike to the dealership and had the exhaust gaskets replaced. I still hear the sound and the Dealership states this is common with an aftermarket exhaust. Is this common with the Alien Head systems?
I have cams from my Gen 2 Hayabusa LSR bike that I’d like to use in my Gen 1 bike. I see your offset cam pin for going from Gen 1 to Gen 2, can I do the opposite? (Gen 2 cams in Gen 1 motor).
I am getting an 08 Hayabusa and would like to install new slip ons to replace the stock mufflers, but the mufflers I would like to use are your CT Series. My question: can I get just the CT Canisters or do I have to get the complete system?

I notice a huge difference in the Pump Gas Track map fuel added at 100% throttle starting at around 7k rpm's compared to the other maps. Is this correct?
I just installed Brock’s ShortMeg full system with the PCIII on my 2008 Hayabusa. Install went very well and runs great, no backfiring etc. But the one issue I do have is the idle now pulsates from 1100 to around 1200 or 1250…just a light bounce. It was very steady. Is this an issue? Is the map the correct one?
Do I need a different map for each setting to use the S-DMS (Suzuki Drive Mode Selector) on my bike.
I had a few questions about the '08 Busa pistons. I was wondering what compression ratio your pistons are. How high can the compression be for a stock exhaust? We plan on doing cams and modifying the exhaust cans internally. I also have the thin Cometic head gasket if needed.
I just purchased a 2008 Busa and wanted to ask about the Alien head pipe and what type of map should I request. Which one (map) would give me the most power for street use?
I am building a stage 2 Velocity turbo Busa. I was told by a friend to remove the balancer on the crank. Hoping I might get your thoughts on this.

On an 08-12 Busa does the stock oxygen sensor go back in the exhaust? The opening for it is blocked off.
I am going to be installing one of your sidewinder exhausts on my 2008 Gen II Busa, I wlll be removing the oil cooler. Do the bock off plates off a Gen I work on the Gen II. Does the sidewinder exhaust off Gen I fit Gen 2.

I have mounted the clutch cushion kit on my Busa. Now I’m mounting a lock up clutch. Do I have to do anything with the spring pressure or will the springs that followed the cushion kit work well?
Will I need a new map if I take out the secondary butterflies on my 05 Busa?
Can the TiWinder be used with the stock oil pan or does it have to be installed with a lower profile oil pan? On the 08 Busa, can the oil cooler still be used with this exhaust?
What is the preferred piston setup for a 1507 Hayabusa engine used for Land Speed Racing? DaveO referred to Brock's "JE piston's made to BDE spec's 84mm." What is the best current exhaust system for this bike as well?
I recently purchased an AH 2 system for my 13 Busa. I haven't installed as of yet because the bike is being painted currently. Do I need a dummy plug for the o2 sensor or any other add ons?

CT single header flanges torque
I currently have an alien head on my Gen 2 Busa and the header is slightly smashed, so I'm considering getting your 4-2-1 sidewinder. My question is, what type of power increase can I expect with your 4-2-1 sidewinder, running it without a baffle. Basically I would like to know the advantages of a sidewinder.

Does the Speedo Healer also disable or sneak its way around the factory speed limiter ?
I am in the process of changing my air shift cylinder from a horizontal mounting below the left footrest physically attached to the adjustable shift rod to a vertical set-up. This is because the bike will not shift out of first gear under full throttle (other gears are working OK). I used to shift my 08 'busa at the drag strip using just an MPS engine kill and the horn button and that was working somewhat OK but I wasn't being consistent enough. When talking to Dan Rudd at the last Manu Cup event, he suggested that I try an MPS auto shift. Now, apparently, I don't have enough power in the (brand new) cylinder in the horizontal position to shift properly so it's been suggested to me by other (good) racers to mount my cylinder vertically for the added mechanical advantage. I would get approx. 2.5 to 1 more advantage. What I would like advice on is the cylinder clevis attachment to the shift lever(clevis slot is about .26o wide and shift lever is about .31 wide). It's been suggested that I just machine or file the aluminum shift lever down to fit the clevis and be done with it. I'm looking for a second opinion on this, also, where on the shift lever is the "best" place to put the 1/4 in. hole for the clevis to be OK with the 2 in. cylinder travel. Any instruction and certainly any drawings on this issue would certainly be welcomed and appreciated. I am a toolmaker so doing this stuff is really not a problem, I just want to do it right the first time. Thanks for any and all help you can give me...Tom.
Are the primaries on the Gen1 Hayabusa the same as the Gen2 Hayabusa? I am asking this as I have a line on a set (of Gen1 primaries) which if I purchase I want to put on my 2009 B-King with a custom mid pipe.
I've have an 08 turbo Hayabusa. What action do you advise that I take in order to to see the bikes speed once I pass the limit of the speedometer, which is 180 mph? I understand there is a product available that corrects the inaccurate speed displayed.
I am considering installing your Alien Head exhaust system on my 2011 Busa and a Power Commander V with your street map pre installed. My bike is completery stock with less than 2000 miles on it. Will I hear deceleration pop or backfire from this exhaust system with the power commander installed and mapped by you?
Why not remove the bracket altogether instead of just the 3 screws holding the PAIR valve block off kit for a 99-07 Hayabusa?
Do TREs alter the Air/Fuel ration on the 08 Hayabusa?
