Alright boys and girls, I have seen a few of these threads and have searched the BadWeb site for answers; but, alas, I have not found the answers. At least, not to my liking. Can anyone tell me if there is a way to increase the rev limiter on the XB's? I am not looking to race. I am not looking for the 10K mark. All I want is 500-1000 RPM bump in the rev limiter. I believe there is more power there, and I believe the engine can take a few short (read un-sustained) bursts without any detrimental problems with reliability. Dear god, please help.  | ||

Logan, I read your profile...remind me to never have you service my bike!   As for the rev limiter, I think its there for a reason. I wouldn't take that motor to levels its not designed to be at... | ||

This is a very scary thread.  | ||

Maybe there is a joke going on that I don't understand. Oh well. Dtx, you are right that the rev limiter is there for a reason. However, I feel that Buell put the limit at a low level to help with legality matters; and yes, longevity of the motor. All I want is a little more poop. If I get on it hard the RPM's run out way before the power runs out. I don't think in stock trim there is too much more power available, but I think there is a little. If no one knows a way to do it with out any fancy racing coolness that is fine. I am not trying to make a thread on whether I should or shouldn't do this; I am trying to ask a simple question.

I don't think there is a method to increase te XB's rpm's. My guess is your best bet is to put in a small cam and with a good proper tuning you get a few more HP and more torque so that you might not need/want more RPM's. | ||

Logan, re: your question: the only somewhat safe way to get what you're looking for is to install the Race Kit for your bike. I believe it includes a new ignition module, exhaust/muffler, and air filter, pretty much it I believe. edit: I see per your profile you already have the race kit, okay, so if you still want a little more then read the archives and talk to the race-prep mechanics in your shop there as there are options available to "racers" that aren't always available to the general public, and since you're now an insider you have a better line on stuff than the rest of us do(or at least I would assume so). I do know that several years ago your shop did have a good race-prep guy working downstairs there. re: the other comments people can't seem to help making: There have been quite a few people have problems at various dealerships. Some of this is what I call "Harleyitis", which sometimes turns a mechanic into a Buell-Hater. Some mechanics in some dealerships (note: I said "some") are very incompetant when it comes to working on Buells, and couple that with a lack of patience to learn the proper procedures for working on them and you have the makings of major problems (at least by some people's tellings of their experiences). Several years ago I rode my M2 from Milwaukee to Seattle, and due to a medicated driver I had to leave the M2 behind at Eastside H-D/Buell. They did right by me, helped me a bunch, and repaired the bike nice and proper, and helped my sister load it into her pickup when it was ready so she could take it home until shipping could be arranged to send it back to me here near Milwaukee. So from my personal perspective I have no problem with Eastside. One item some may be picking up on in your profile is your quote "what are pushrods". Not very instilling of confidence coming from a Harley/Buell mechanic. Also your telling of the problems with the bike, those sorts of things should never have happened - not even for a reasonably patient home-based do-it-yourselfer. The final thing that may be throwing people off is where you say you prefer Euro and Japanese bikes, but then say all bikes are just two wheels and a throttle. All this speaks of someone new to the world of motorcycles, not that there's anything wrong with that. But sometimes you just need to get some seat-time in, log a few hundred thousand miles on various bikes, and tear down and rebuild a few bikes from the ground up before you can really appreciate the differences that different bikes offer. My gut reaction is that you're new to bikes, new to being a mechanic, and as such you have lots to learn. I don't know how LWVC is these days (I went there back in the 1970's when they were still scattered in numerous after-hours classrooms in various schools before they built their new building), so I can't comment on their mechanic school except to say that I hope they have a decent program. But I will tell you that one engineering supervisor used to say when he hired engineers out of places like Stanford and MIT - "In school they learned the theory, it takes a few years to retrain them in reality" . Basically, there's book smarts and there's world smarts, and it's possible to have both, but too many people have the former and feel no need to learn the latter, so we of the latter have issues with them at times. Your education gave you an introduction and invitation to join the field, your experience and continued learning will add to your applied knowledge. Sorry if this comes across as preachy, it wasn't intended to, it was just my feeble attempt to quell the pseudo-flames of those above me in this thread. If your bike already has the race kit and is tuned well and if the suspension is set up proper for you then learn to utilize what it has available and you may not feel the need for those extra 500-1,000RPMs you're longing for. Stick around and keep us informed of how things go for you in the shop there. It would be great potential reading to hear how someone new to the field progresses in understanding and knowledge as book smarts and inexperience are replaced by applied knowledge and caluses. Welcome to the world of Buell where a few extra RPM's isn't always the right answer.  (okay, my fingers are tired now, time for a nap.....) | ||

Mikej, Thank you. You are right, I am a new mechanic. I was a service writer for both Ducati Seattle and Eastside before wrenching. I know that there are "Harley mechanics" that will not work on Buells--in fact, we just fired a guy who had that mentality--but some people need to realize that not every one is like that. The management has made the request that I be their "Buell Specialist". I don't know if that is just smoke or if they really want that. I do however know that I don't want to be "that" guy. So, I will try my best to succeed in the proper way; this will include HD and Buell training courses and working directly with the master tech at our shop to learn the "real world" of motorcycles. Ryker77, I think you might be right about the cams and tuning the power to where I want it. I was just curious about what was available. Thank you.

I removed the rev limiter on my bike by donwloading the map and uploading it back to the ecm while learning to use the software.. I honestly regret to have done so, as I did not mind only reaching 7500 rpm and I now have to be careful on the revs I am taking in 2nd 3and 3rd gear.. On the other hand when I was much younger and had a 350 yamaha RZ (two stroke engine)(amongst others)I could not wait to hit over the 6000 rpm range, downshifting from 4th to third and hiting hard the power to have the wheel spin during cornering like the grand prix motorcycles.... I remember exactly what an idiot I was !!! But hey, I now have an xb9r and I guess its all become a question torque and you already get plenty with 7500 rpms.... I now reach 8000 RPM and could probably go for more, but truly it does not give me much more.... But then again if you truly want to go for more rpm, big time and often, think of all the other changes you may have to do ! good luck anyway... | ||

Logan, see if you can find a way for your shop to send you to some of the Buell events, be they rides or gatherings or races. You'll get to meet people from other parts of the country, see what various owners have done to their bikes, learn what works and what doesn't, what folks look for in a dealership and what they go out of their way to avoid. All of this info, and I do mean all of it, you can take back to the shop and apply it. You'd also do well to watch the postings of Daves on the site here and see how he interacts ( and even sometimes admonishes ) with the people hereabouts. The Daytona 200 would be good to attend, as would the races at RoadAmerica here in Wisconsin which would also get you a tour of the Buell factory and you could also fit in a tour of the engine assembly plant if the tours are running when you're here. If nothing else watch the local events and rides near you, watch the StormFronts section for your region, and get to know the locals. Take everything with a grain of salt as many folks have festering open wounds from past encounters lurking under lightly healed skin. But if you get past all that you'll find another wealth of knowledge to be gained that you can apply. And for a little insight of what some folks are doing spend a bunch of time on buell.com and look at the details of the XBRR engine, at least the one's they're letting you see. A bike is a bike, some just prefer one over another 'cause each one is unique and different in its own way. In any case keep us posted of what you do to your bike. Especially if you "pork chop" the flywheels like the XBRR engine. | ||

Mike, Fantastic posts above. You have a real talent for being tactful.  A talent everybody who uses internet discussion boards should have. Nice! | ||

Therenardo, can you please elaborate on your quote above: I removed the rev limiter on my bike by donwloading the map and uploading it back to the ecm while learning to use the software.. A couple of us are curious how that procedure can be replicated. Thank you. Dean | ||

One way (for those that have a 12 anyway) is to use an XB9 ECM with a direct link tune... That's what I plan to do with my racebike. | ||

[Bonsoir, It's really hard to elaborate, I never actually knew what really happened, as I downloaded my stock ECM XB9 map to see it, and uploaded it straight back AS IS by mistake (never ever meant it !). I then decide to go for a spin, the next thing I know is that It isn't rev limited anymore. I remember thinking that maybe the software removed the rev limiting by default as a feature ! I was hiting 8500 rpm straight away. In June, I bought a XB9race ECU and decided to do the same thing. In between I had also changed direct link software versions (having done the translations in French, I wanted to check it out).It didn't happen again, was it a software or a map issue .... Don't know.. But I still have the original recovery map .blm and all my .blo files for direct Link and am happy to send them out if you wish. Best regards Fabrice PS. You don't get anything more with 8500 rpm exept, the longer gear, and the noise...! I didn't do it often at all, and the bike is still thrushing hot ! ] |
