I recently bought an 03 XB9S with only 1,100 miles. I'd like to upgrade it with the race kit piece by piece. First I've ordered by 12 airbox many have recommended. When I get it I'll get the airfilter, remove snorkel and try it. Next I'd get the kit muffler. And finally go to a dealer for the ECM/TPS reset. My concern is that this piecemeal approach could cause a lean condition when the airflow into and out of the engine have been increased. I'm trying to space it out to save the larger cost of buying the complete kit at once. I'll spend the dough, but just stretched out longer. I'm new to Buell, but I make up for it by being old! (70) Thanks for any advice. | ||

It won't cause any problem that will cause a condition lean enough to hurt the motor. Lots of us are running pipes and k and n filters without the race ecm. | ||

Shorty, I have modified my airbox (just posted pic's), running a K&N, removed the snorkle, and drilled a few holes in my muffler, all without a single problem. I had my TPS reset at the 1000 mile service point and all the mods were after that. | ||

After you make the modifications, ride the bike at least 20 miles at like around 4000 rpm or so and the ECM will make adjustments automatically to stabilize the air/fuel. No TPS reset needed and it will all be good. Mike. | ||

No amount of riding around helped my race ECM. I would suggest getting the whole kit as a package (provided your happy with the Buell race pipe) and dropping by the dealer to have the TPS reset once you install it yourself. | ||

Regardless what mods you make, including Buell's Race Kit, you are not going to know for sure if you have a lean condition until you run it on a dyno with an exhaust analyzer. Therefore, I would suggest making all the mods you intend on doing and getting to a dyno. If you have a lean condition, the new Techlusion DFO should correct it as the old style did on my X1. Better safe than sorry. The stories of holed pistons (Pre-XB Engines) created by a lean condition got me to do the Dyno before, during and after the mods. Mine was lean in stock form, and worse after the addition of the K&N filter, gutted air box and a V&H pipe. So we installed the DFO. It balanced the mixture nicely but I ended up with a surging problem. The addition of the RACE ECM and another Dyno run made everything work together as intended and I am a happy camper. The thing to remember is all the performance mods just make your bike faster. The DFO compliments that by making your fuel injected bike last longer just like changing jets on a carb. If you are a maximum performance type that doesn't mind tearing down your engine like a race crew, you can omit the DFO. Then again, if you are a guy that likes to ride more than wrench, you may want to do the dyno thing to see if a DFO will help. Why live on an assumption when a simple test will reveal the truth and possibly save you from a catastrophic failure. | ||

Starter - Please read and understand the original post first. He was asking about a 12 airbox, snorkel removal and K&N filter: "I'd like to upgrade it with the race kit piece by piece. First I've ordered by 12 airbox many have recommended. When I get it I'll get the airfilter, remove snorkel and try it." For those steps, the ECM will compensate if it has to. I think Captainplanet and Odie got it. But, when he does get the race ECM and muffler, then the TPS reset will be required. Mike. | ||

Obviously I missed something, but what exactly does the 12 airbox do over the 9. In the service manual,(part numbers) the only diff between the two is the top, ( cover) which is this way due to the recessed area for the stepper motor for the 12 interactive exhaust? Unless it is this reduced space under the lid. Someone? | ||

If you look at the inside of the airbox, there is a nipple that helps with the airflow adding about 3hp average to a 9. | ||
| Deerhunter17 |
if this nipple helps w/ airflow ( by design ) then how does dilling holes into the box top further improve this flow? | ||
| Wyckedflesh |
the holes allow more air into the box, the holes are drilled outside the filter area, the nipple is inside the filter area. | ||

okay... you get the feelin I could be screwin with ya yet?... Sorry, just a few beers and a mood brewin..  | ||

Are you sure I am not screwing with your brain? How do you know what I just said was pr0n induced I mean I am talking about nipples... |
