I'd like one also. From that photo, it looks like you first push the rod through and then turn it so the slot is showing. Then push the brass butterfly plate through and then loctite the screws into it. Right? (Message edited by electraglider_1997 on July 15, 2010) | ||

I'll definitely buy a set. Looking good! | ||

More creative innovation - NICE job Tootal! Not a machinist or engineer, but just wondering if you milled the side the butterfly attach's to by 5 or 10/1000's, to provide a a flat spot to rest on, instead of curved surface...would it defeat the purpose of the more robust design ? | ||

Is this just a problem with Uyl's or all XB's, | ||
| Electraglider_1997 |
Jphish, If you look at the photo, I'm sure the butterfly plate fits through a slot milled lengthways down the center of this newly machined rod. That rod slot would be flat all the way across. You'd have to slide that plate through the slot to mount it. It's like the original rod but without all the meat taken out of the rod just a flat sided slot. | ||

Thanks for the clarification 'Electra. My old tired eyes sometimes deceive me. I damn near require binoculars to work on the small stuff anymore. j | ||

Is the design of the shaft the same on the newer XB's, 08 XT for example? Is this a part I should have on hand so it can be replaced in a few years or did Buell recognize the problem and change the design after 06? | ||
| Towpro |
Now I see the slit where the butterfly goes through. Great design. But looking at the original design, why would it brake where it did? It would take resistance on the dumb end of the shaft to cause the shaft to brake like that. I do recall seeing a throttle valve before with slits in the shaft as opposed to a flat releaf, was it Rochester? (it's been a while). | ||

Motorbike - I have never heard of an 08' or newer XB with this problem. Mostly confined to 06' and perhaps a few 07's. If I'm mistaken...I'm sure someone will chime in. Another nice thing about this board is... usually the 'facts' will win out. | ||

I'd like to be on the list as well. And thank you for your effort on this project. Very well done!! | ||
| Glenn |
I'd like to be added to the list too for a 2007. Thanks! | ||

Ill possibly take 2/3...I have a few Buells to take care of for a while(forever). I have a BC Gerolamy modified t-body just sitting now with a broken shaft. Let me know $$$ and when your ready. Thanks in advance | ||

First off, Court, thanks for your approval, it means a lot. It was a pleasure to meet you at homecoming. To the rest, thanks for the kind words. We all have our expertises, that's what makes the world go round. I talked to my cousin tonight and he keeps harping about the slot. That's a time consuming part of the job. Time is money as they say. He's getting ready to go on vacation next week so it will be at least a week before he starts adding it all up. We went to trade school together and he's very sharp so I started insulting his abilities!! We'll see if I did any good. This conversation was over a few beers by the way! Sorry I didn't show the slot, that would have been nice! My camera battery is dead so I'll charge it up and see what I can do. One thing my cousin mentioned was that he could get oversize stock, machine everything and then centerless grind it to size. That would be a real piece of art!! Should know something in a couple of weeks. Thanks for your patience. | ||

Hows about burnin' the slots in via wire edm? Depending on the demand it could be done cheaply. I can check with the guy who does all of my wire work if needed. | ||
| Electraglider_1997 |
I used to have many parts electrostatic discharge machined when I worked for AT&T, Lucent and Avaya. Good option and very precise. | ||
| Paul56 |
Wow, that's beautiful! I will gladly put up with a couple more more weeks of driving to work to get that. Looks bulletproof. Great job. I need one! | ||
| Tootal |
  Wire edm was considered but it would be expensive to set up. I think I'll make up an arbor for a small slitting saw and we can come in from each side on a horizontal plane, that way we don't need to index it. We'll figure it out, if there's a will there's a way. Hopefully the above pictures explain it better. EG, the way the screws are put in is once your buttlerfly is centered in the bore you tighten the screws and then rotate the shaft to expose the back side. The holes have a small countersink so you can back the shaft up with a broomstick or plastic rod etc. Take a small chisel and split the screw perpendicular to the shaft. This will force the screw into the countersink and won't allow it to back out. That's how my factory Keihen carb, off the harley, is done and I've built many of those and never had a screw loosen. I love loctite but in this application I prefer physical inability over glue. (Message edited by tootal on July 17, 2010) (Message edited by tootal on July 17, 2010) | ||

Here is a photo of the shaft that failed on my 2007. Looks the same except the pin hole on the TPS side appears to be drilled 90 degrees off from the 2006.  | ||
| Tootal |
The hole in the 06 is actually 5 degrees off of the centerline of the butterfly. I don't know if the 07 is 90 degrees from that or is it perpendicular to the butterfly. I was thinking that I could find that out and drill two holes so you could just put your pin in the hole you needed and make it a multi year part but in your picture I see the diameter is turned down too. That's different from an 06. Another thing, is your shaft 8mm in diameter? .315"? If it is and the 07 sensor needs a turned down shaft then my idea of making a universal replacement might not work. If we can do this job I would make the 06 model first. If you or someone would send me a broken 07 shaft then I could modify our 06 to work for you. The differences look small, something you could do by hand if only a few are required. | ||
| Dirt |
Tootal, Good eye, I didn't notice that difference in diameter near the TPS for the 07 vs 06. I measured the diameter with a cheap pair of calipers and the step is 6.9mm while the remainder of the shaft is 8mm. It is hard to tell from the photo but the hole on the TPS side is not exactly perpendicular to the butterfly. Based on your photos, I estimated it was 90 degrees different from the 2006 or 5 degrees off from perpendicular. It's all yours, if you like. PM me your address and I'll send send it your way. | ||

Anyone report shaft failures in 2008 bikes? My shaft snapped on my 2000 X1 in the same way. The X1 repair was under $100 though! | ||
| Tootal |
Dirt, thanks for the offer. Let me be sure we can produce them. If so I will take you up on that.  | ||
| Motorfish |
Is it possible/cost effective, to use a replacement `06 shaft (Tootal`s),and a `06 TPS, on a `07, instead of making or modifying a `06 shaft? Just a thought. | ||
| Jlnance |
I am very excited by this thread. | ||
| Rudolf35 |
I am in! Once this hits the "market" I would be more than happy to have one! The butterfly is the last "back of the mind" issue that I have about my Uly.Getting one of these would put me totally at ease running the Uly.  (Message edited by rudolf35 on July 22, 2010) | ||

Put me on your list also Tootal when you're ready to start the manufacturing process. Thanks for the fine work! | ||
