I bought my 1st Buell xb 12 a few months ago the power band seems a little jerky to me it pulses a little. I'm use to riding 4 cylinder rice bikes with a nice smooth power curve I love the looks and the sound of my buell and it fits me so well (short guy) Is this typical of a v twin?? | ||
| Wantxbr |
You sound like you've never ridden a V-Twin. That jerkiness is torque. That is very typical of a v-twin motor. Have Fun you have a lot of torque in that 12 for you to enjoy. | ||

Yeah, my XB12Ss is downright bothersome to control in parking lots. Lots of lurching and surging about with a steady throttle. Slightly off subject, it always amazes me how these engines transform around 4-5000 rpms. They unsteady, shuddering rumble becomes a super-smooth roar, and I can actually make out cars in my mirrors! ~SM | ||

drag the rear brake a little during the slower speeds, itll allow you better control. itll smooth out the power delivery and if need be, allow you use of higher RPMs without going too fast. use the clutch for control. also, make sure the bike is warmed up. | ||

At slow speeds the bike is jerky. For me, it also sometimes surges at higher speeds. I think this is what he is referring to. You can keep the throttle steady at say 4,000RPMs and the bike will feel like you are going on and off the throttle a bit. I assume this is related to the FI. Is that a correct assumption? | ||

Hmmm.... mine doesn't do that... It did with a power commander though but only as it transitioned from closed loop to the open loop mode. Went away completely when I removed the PC. As far as low RPM... It may need a TPS reset. Have you done anything with the airbox? | ||

+1 on a dragging the rear brake. Its a stunters best friend. I would speculate that it is a combination of the camshaft profiles, and the 45 v. It could probably be "cammed down" to help a little, but you would still feel the 45 v, and your redline would drop to 5000-5500 or something. And we wouldn't won't that would we. If you've ever driven a cammed up car, with a manual tranny, you would experience similar effects. Just think of your XB as a "Musclecar". I think of mine as a '70 429 Stang.  | ||

Just think of your XB as a "Musclecar". +1 on that description. comin' off an IL4 to the twin is different and vice versa. my brother and i swapped bikes just yesterday and i was reminded of this. i ride an xb9 and he a 636. we are the same about cars. take little bro's 3000GT vs. my old el camino. you've gotta get the high rev mitsubishi 6 cylinder way up in the rpms before it hits "the powerband" and starts to really pull. on the elc's small block chevy, there is no narrow "powerband." you press the loud pedal and it's instant delivery. sure the chevy runs out of steam before the mitsu does on the top end, but you don't have to count to five before you get pushed back in the seat.  | ||

I think of mine as a '70 429 Stang. I am offended for my poor Buell's sake. How dare you compare it to a Ford! ;) I have never ridden an inline 4 and the Buell is the only street bike I've ever ridden and I have always thought of it as a muscle car. It just acts the same way - low redline, tons of throw-you-back-in-the-seat torque, and not too much top speed. Thank God it doesn't handle like a muscle car, though! | ||
| Jwhite601 |
Love my Fords, and my Buell.   | ||
| 07xb12scg |
All that land...I'm jealous. I would have a field day with my QuadRacer! Really nice bike BTW. And and that's a lot of Fords for sure, but is that a silver/gold Chevy I spot behind the fence and tree in the top right? | ||

Some people can't be helped! Or as Ron White said. . .  J/K Jwhite! Where do you race those things? Stop by our site and check out our hotrod. . .HayWire Racing | ||

Mine is jerky in first at low rpms, and it likes to idle on 1 cylinder alot, too...the latter of which I like to blame on the Ford parts!  Anyone else notice the FORD injector connectors?? | ||
| Xbullet |
hey, the points on my old shovelhead are out of a '66 chevy. what can ya do? | ||
| Barker |
there's alot of ford parts in your XB. Injectors, TPS, fuell pump, IAT sensor and a few more. Ironically the 02 sensors is out of a 92 chevy pick-up. | ||

| Barker |
here is a pic I took while replaced a throttle body on a 03 XB9R  Jwhite601, I ride alot in your area 141/70/231/96 let me know if ya wanna run around with another bueller. (Message edited by barker on June 27, 2007) | ||

Terrys, The belt drive system adds to the jerky feeling. It has no slack so its a bit more immediate the chain systems. I had the same felling you had with my first XB. After riding it for a while its not "jerky", It just feels like my wrist is attached directly to the rear wheel. An out of whack TPS could be the problem. Sad thing is most stealerships dont set it correctly | ||

The way you're always hyping the Jap bikes I thought you were speaking from experience. I don't "hype" them. I give them credit where credit is due unlike some people on this site. | ||

I have never ridden a bike that is easier then my Firebolt to ride smooth in the twisties. The heavy flywheel and excellent FI make on-off throttle transition easy as does the near 0 lash belt drive. As for low speed maneuvers...like has been already said slip the clutch and drag the brake to take the lash out of the drive train and give the motor something to pull against. I guess I just don't understand some of the complaints some people have with smoothness? My other bike is a Bandit 1200 I-4. The Buell is smoother. | ||

I don't "hype" them. I give them credit where credit is due unlike some people on this site. How would you know where to give them credit if you've never actually ridden one to compare. That's the problem with people nowadays - politicians, scientists, journalists. People who's job it is to know don't take the time to know anything. | ||

People who's job it is to know don't take the time to know anything. OK I see you're going to attack every comment I make about Jap bikes now. I have never ridden a Japanese street bike and I freely admit that. I do know a ton of people who own them and I help "work" on them. I don't have to have ridden one to know how reliable they are and give the Japs credit for throwing an insane amount of technology into a bike and making it cheap. Plus, it's common knowledge that any new Jap sport bike will smoke a Buell in a straight line if the riders are equal. It's not like I come on this board and tell people things I would only know by having ridden one. | ||

Barker, I work in Westmoreland and live in Hartsville. I get to ride 141 2wiceaday  . Terribletim, Me and a Friend were racing them at Riverview Speedway in Carthage TN, until they shutdown in 2004. We have just learned that it has been purchased and will be reopening soon.  07, Jap bikes are NO MORE RELIABLE than a Buell. I've worked on'em all. Did you see the pics i posted of the Suzuki frames breaking. Well if you register at stuntlife and do some digging, you'll find that its very common for them to crack frame welds. I've seen 3 cracks in 3 different spots on a GSXR with 10000 miles of daily street riding, no stunting. If you had a Busa(the fastest Jap trap) sitting beside your Buell in the garage, i'd bet you'd ride the Buell 4 out of 5 times you went riding. My friend has an F4I, and everytime we get ready to ride, he can't last longer than an hour, his wrists start to hurt and his ass gets sore, I'm all comfy up on my Buell ready for another couple hrs. We swap bikes on a regular basis, and honestly, i wouldn't swap my Buell for 5 of them. Sure the Honda is faster(after 85-90) but he has yet to get away from me on my slow Buell. As a matter of fact, I sometimes have to slow and wait for him. Sometimes i have to pick my spots, if you know what i mean.  | ||

07, Jap bikes are NO MORE RELIABLE than a Buell. I'm only speaking in terms of my experience. My Buell is the only Buell I have experience with and in less than 4,000 miles it has had more problems then all of my friends' Jap bikes combined IF you don't count breakdowns caused by them (chain snapping and causing damage to the engine cover because of constantly clutching up wheelies, plastic repair because of endoing over, etc). I did see the Suzuki frame pics. That definitely isn't a good thing to see, but I can would feel confident that they're safe for riding. I may like my Buell better. I won't be sure until I try the Jap bikes. When I get a new job I will have the best of both worlds - a Buell and a Jap bike. You can never have too many toys!  | ||

"You can never have too many toys!" Amen on that! ~SM | ||

If its an xb12r try adjusting the cable for the exhaust valve it transformed my bike. | ||

" Well if you register at stuntlife and do some digging, you'll find that its very common for them to crack frame welds. I've seen 3 cracks in 3 different spots on a GSXR with 10000 miles of daily street riding, no stunting. " Great example,a web site called "Stuntlife" gee I wonder why their frame would crack. "If you had a Busa(the fastest Jap trap) sitting beside your Buell in the garage, i'd bet you'd ride the Buell 4 out of 5 times you went riding." I know alot of people who would like to take you up on that bet,including me. " My friend has an F4I, and everytime we get ready to ride, he can't last longer than an hour, his wrists start to hurt and his ass gets sore, I'm all comfy up on my Buell ready for another couple hrs." Do you have a Firebolt or a Lightning,big difference in comfort.I see alot of people taking long rides on Japanese sportbikes with no problems.} | ||

I know a guy who has a 05' Gsxr 600 and a XB12s and guess which one he rides more the Buell of course... Btw Is there a cross reference of Buell parts and Ford parts out there somewhere so could shop for parts at the local auto shop for my buell? | ||

Plus, it's common knowledge that any new Jap sport bike will smoke a Buell in a straight line if the riders are equal. Well for the straight line thing your right, but the rest not so much since it doesn't take any skills to go fast on a straight line, anybody can go fast on a straight line even my 14 years old boy could if given the permission lol. | ||
| Jwhite601 |
Pup, you live in FL (Land of no curves) of course you would want the Busa, so would i. Here in the rest of the world we have hills,mountains, and CURVES. No way that big ass Busa gonna do shit up here in my neck of the woods. I've got 3 friends who've bought and SOLD them. ALL within the 1st yr. But i could really see having 10 mile long straights like FL, and wanting the Busa. |
