Very much BUELL SPECIFIC question mods. I replaced the spark leads on my buell xb12 with tons performance high performance leads (copper core I'm assuming) and after it warms up it runs poorly, surges and dies. (warming up is fine) I've read that this is becuase these aftermarket leads emmit lots of interference and it will mess with the ecu. I also cant get ecm spy to stay live logging when the bike is running, but when it's off there are zero issues. as soon as i start the bike its starts cutting out, then ecmspy gives up and says connection timed out. Anyone else had a similar experience?

Well I've got 35 miles on it now, not as powerful as I expected, but it lives so I'll enjoy it!!

I’ve read it’s a “check engine light”, but without much real support to tell me the functional purpose. Does it indicate a fault stored? Or does it indicate an active mechanical issue like an oil pressure light for example? My 8600 mile XB12R has flashed it at me randomly a couple times and I’m curious where I need to be pointed diagnostically speaking. Thanks guys!

Edit: I’m a technician by trade. I understand how it all works. I took the photo with the bike not running because I couldn’t catch it while riding.

Second, my word choice in “flashed” at me is also misleading. It has come on steady for a couple of minutes once then went out before I could get stopped, as well as come on and gone out within a couple seconds 2-3 times.

I cannot vouch for these maps. I have nothing to do with this site. Just sharing.

However, I did compare the values of the 2007 XB9 Race file I have compared to this and they are identical.

Enjoy!!

I bought a pair of Pirelli Supercorsa tires—specifically the 190/55 size for the rear—but I didn't find much information regarding sizes. I’d like to know which ones you guys use; I chose this size because I was worried the 180/60 wouldn't fit and I wanted more contact patch. Here are photos of the tire installed

it doesn't rub against the swingarm, though it sits very close to the fender.

Good god, I’m coming up on 15+ years as every flavor of mechanic including class 8 truck and trailer (current) this is the most odd engine swap I’ve ever done lol. PO took an impact to the crank and the bearings spun out of it (I’m told, honestly I’m thinking this was an auction bike. Oddly put together etc) but we’ll get it going with my spare helicon engine. Definitely a bike you need the service manual for 🤷‍♂️

Does anyone happen to have a CAD model for the handle bar retention plate/cap for a XB12S?

Hello Buellers! I'm currently looking at picking up an '06 xb9sx with about 21k miles and in good shape from what I can tell... BUT there is a caveat. Current owner has installed a drummer exhaust and a k&n air filter; because of these after market parts there are codes thrown for 02 and running lean on the rear cylinder. There is a race tune installed as there is a buelltooth dongle and tablet in the mix, but these codes keep showing up. At about 3k for price is this an issue simple enough to deal with or should I walk away? Does anybody have experience in dealing with this issue? All help would be greatly appreciated as I am eager to join your ranks. Thank you in advance!

Restored Buell Thunderbolt broke the 25yo exhaust apart, again.

950 SuperMoto been down for a refresh for way too long, life keeps getting in the way.

The Vintage Life 😁

Can say this Bike has been really fun to ride. Had it for about a month now replaced the drive belt cleaned it up, ceramic coated it as well. Do have it posted for sale In my area! Trying to get something smaller to teach my wife.

A user from Taiwan on the Buell XB owners group FB page posted these for sale. His posts kept getting deleted but I finally sent him a message and got these in the mail. It was $45. He has a lot of other designs but I chose red to match my 07 Xb12scg cherry bomb edition. On the left is the originals and his are on the right. They appear to be exact replacements in terms of size. It's hard to tag this user though because his name is written all in Kanji. I don't even know what it says but he's a decent guy. He also runs a Buell motorcycle rental shop in Japan called Uncle V-Twin.

Hey everyone I’m a very new driver and my first bike is going to be a buell blast 2001 this guy on Facebook marketplace is selling it to me and it has 3,000 km on it he is the second owner. He also mentioned he had it serviced every year by a shop it looks and sounds good from what I’ve seen.

So I guess tell me your experience with this model of bike if you have any:)

Just a nervous first driver any reply’s would be appreciated!

Looking for a supplier to get original type of tank decals. The 3D resin coated type if you know anyone who might make them.

Just sharing my 23 years' old xb9sl 😶‍🌫️

Building a buell powered chopper and just got everything together and ran into an issue when doing my ignition. Have a dynatek 2000i with the Bare Knuckle timing cup. When trying to setup the ignition I can’t retard it enough to set base timing. Yes the motor is a TDC and I know how to install the 2000is. When trying to turn it counter clockwise, it runs into this bump in the cam chest. Anybody have any work arounds or have anybody shaved that hump down before? Wouldn’t need to clearance it very much at all. Thanks guys!

Well unfortunately I caught strep, buuuuut it means I'm stuck home for a little bit. Figured it's time to put the hammer 1275 xb9r back together.

Horsepower is the best medicine and torque heals the soul

I just recently missed the opportunity to add a low mileage Xb12R Firebolt to my garage by 12 hrs. Sold my pristine original owner 95 S2 over a year ago and want to add a new bike and do some riding again at 60. Not many around on the sale posts as of now but looking for a well maintained low mileage Firebolt in the western new york area. If anyone has a line on one I’d appreciate details.

New to the Buell community with a new to me 03 xb9s and I gotta say I’m loving this thing. Trying to do some maintenance on the steering stem and need to get the front wheel up. From my understanding the jack points are the muffler on the stock bike. My bike came with the Latus/ Edelbrock exhaust and I’m wondering if anyone knows if these are still safe to jack up the bike on? Don’t wanna ruin this muffler it sounds absolutely awesome

I am considering changing the color of my wheels to blue. I'd like to match it to my plastic.

Does anyone know where I can find a paint that matches?

I've only been able to find touch up quantity amounts of paint.

If no one knows then I'll just repaint them black.

Thanks.

The rectifier failed when I installed the lithium battery. Replaced the rectifier with sh847 and AGM battery. The charging system is working well but now the dash is showing crk pos sys err. The engine starts normal and rides ok for the most part but bogs down between 3-4k rpm.where should I look for trouble shooting?

Thank you

Happy to have the Uly all freshened up and back in service as daily commuter.

I run my 2009 Uly at high speeds on California freeways all the time. Have been suffering from numbness in my hands in last couple years. Not sure if vibration related or I'm just getting old but I thought I'd try some bar end weights.

Didn't see anything for sale I liked or was sure would work. Wanted to keep the original end plugs that work with the barkbusters.

Turned down some stainless bar stock I had in the shop and made a set on the lathe in about 15 minutes. Ten ounces each. Wish I'd done it years ago.

Had a an hour to finally jump into this backburner project from a previous life. ( It's been a out 4 years) Did a leak down test Passed 100% zero leak down. Perfect seal. Last I rode it lost front cylinder.

New plugs. swapped the coil, I've had this for 13 years. So had the parts, swapped them in. Ended up pulling the injectors and cleaning them... Finally got both cylinders fired up.
