I hate the look of my rear pulley. I plan to PC the swingarm and tail section blank, and would like a new pulley to PC black as well. Since I have no intentions of paying the big bucks like Wilson  I was thinking of having a shop modify mine like this:  How much would you charge me? Feel free to post up or PM me. Thanks! | ||

I put that exact question to this guy, Tom, in Rodeo, CA. Their info is here: 3rdstreetharleyparts.com He said it would be 'about $100'. He doesn't take credit cards, nor checks. I plan on doing it soon, just don't have the loose bucks right now. In the meantime I've accumulated a library of designs, to decide exactly what I want. | ||
| Scott_in_nh |
can you share that library with us JV? | ||
| Jramsey |
It would be cheaper by the dozen so to speak. Setup on a VTC about an hour, run time 2 minutes. I wouldn't do it on a manual machine and I'm pretty bored at the moment. | ||
| Scottorious |
yah if a bunch of people decided on one design I would send my pulley to help split the cost. | ||

Call Mark at Crossroads machine...I believe that he has a pattern like that if Aaomy in not interested in making a copy of his. (Message edited by Rickie_d on February 11, 2010) | ||

I like that design you have there Andy, I would be in for that unless someone posts a different one. Provided of course we try and do a group thing. | ||
| Andymnelson |
Is there a board sponsor that does machine work? Perhaps a limited run for those of us that want them done?? Any one know who we might be able to ask? | ||
| Brinnutz |
I don't plan on dropping $500 on a pulley, LOL, but I'd possibly send a stocker off...=) | ||
| Guell |
that pulley looks great, id be in for a group buy when it happens. | ||
| Snp304 |
I'd be interested in a group effort as well | ||
| Andymnelson |
Scottorious, Blackm2, Brinnutz, Guell, Snp304...PMs sent. | ||
| Scott_in_nh |
I am interested too.... | ||
| Brinnutz |
I have a friend of my dad's who owns his own business in his pole barn...I'm going to see what he can do as far as possibly making an aluminum one. My neighbor is also one, we'll see. | ||
| Fasted |
me too, please | ||

How would it affect the structural integrity? | ||

>>>>How would it affect the structural integrity? That's the question, since the one big recall on the Blast was for precisely the pulley exploding issue, I've been dying to ask. Has anyone analyzed it or is it just "trial and error". I do know that when they were designed there was an effort made to remove all material (mass) that was no absolutely necessary. Interesting bar talk I suppose . . . | ||

I do know that when they were designed there was an effort made to remove all material (mass) that was no absolutely necessary. Are you still speaking of the Blast pulley here Court? As we all know the tuber pulley is basically the same as the sportster pulley and I don't think anybody has ever accused HD of removing any unnecessary mass!  I bought a spare pulley just to have it modified and will test it at the dragstrip. FWIW over the 4 years I have been here I have seen quite a few pictures of modified pulleys and only one report of one that broke, but it was way more cutout than what is pictured above! | ||

>>>>I do know that when they were designed there was an effort made to remove all material (mass) that was no absolutely necessary. Court – I believe that to be true with the designs that Buell developed themselves for their models. I would not cut one of those if my life depended on it (because it could). I do not believe that same premise to be true to the HD pulleys that Buell modified for the tubers. They just enlarged the register bore on a design from 1977 or so? Never the less I would still be leery of cutting too much from even those bulky units, since I have no analysis data. | ||

"I don't think anybody has ever accused HD of removing any unnecessary mass!" as they say on facebook, "10,379 people like this" | ||

Court started me thinking about all the forgiveness incorporated into designs where the owners can change alignment of spinning and whirring gigabobs. The pulley pictured above was designed for bikes with axel adjusters and if there is a screw, somebody is going to turn it; whether they know what they are doing or not. So…what I am saying is make sure your pulleys are aligned if you are doing to start whittling bigger holes in them. | ||

>>>since I have no analysis data. Buell did and lots of it. Initially, with the 1998 S1, the FEA and Analysis work was confined to several parts such as the front rotor. (I have a collection of tested "donor rotors" in my office) Later . . as a number of Tests and Analysis Engineers were hired and it evolved to it's own department . . MOST parts were subject to very detailed analysis. No designer or engineer wants an ounce of weight on a bike that doesn't serve a purpose. It's sure something to think about . . . it'd be a REALLY bad part (those of you who recall the wooden cart on the ramp in 8th grade physics know why I'd be more concerned about something on the back of the bike than the front) to loose "at speed". Just something to think about. | ||

By the way . . . as much as I dig the LOOKS of that pulley posted at the top of the page you can . . . just intuitively . . look at is and see that the stresses end up in completely different locations than on the stock pulley with holes. The round hole is a very important design element as some of you who studied the structural engineering recall from the studies of eggs and why holes, round ones, are drilled on dragster parts rather than cutting the center out of a piece. No clue on my part but it sure is interesting to look at the various configurations and pencil in where the stresses would end up. | ||

For the moment I will post one that went a little too far. "Don't try this at home, folks!" I will upload the rest later. Many, if not most, came from this site.   | ||

Ah it reminds me of stopping in at H&D Doctors (an aftermarket H-D shop) in Berlin, Germany in 2008. Everytime I've been there - OK, so it's only been twice - there's been a Buell or 3 hanging around. There was this SWEET X1 sitting waiting for it's turn getting repaired:  Gee, I wonder what an X1 in that good of condition could be in the need of having repaired:  That's right, the rear sprocket failed:  I thought I remembered seeing the same bike at the previous years MSM (Mid Summer Meeting) put on by BORG (Buell Owner and Repair Group), and although some componentry is a little different, I still think this is the same bike (or one helluva knockoff...) just a year before:  So apparently this is 'a little too far':  Analysis - up front - is a DAMN GOOD thing! 1313 Speaking of analysis Court, check your Email... | ||
| Court |
>>>>Analysis - up front - is a DAMN GOOD thing! Kinda my thinking. When Abe and his group went to work on the sprocket I'd bet one of their goals was to remove as much weight as possible. 1313 would understand the engineering better than I would but it would also make a huge difference (going back to the drilling many small holes rather than one large one) the shape the material is removed in. | ||

I'm no engineer but my father was a toolmaker in the UK. He always said," If it's made that way, it's made that way for a reason! If you think you can improve a product always test your changes before you come to rely on them." I always took this piece of advice seriously when altering anything on any vehicle. Chris C | ||

Did Buell actually design the pulley on the tubers from scratch? Cuz it looks identical (other than the center hole diameter) to the HD pulleys from the 80's... | ||

Did Buell actually design the pulley on the tubers from scratch? Cuz it looks identical (other than the center hole diameter) to the HD pulleys from the 80's... You're correct. The tuber rear sprockets were just H-D rear sprockets with the center hole machined out to adapt to the Buell rear wheel. What Court's referring to "When Abe and his group went to work on the sprocket" are the sprockets for the XB and 1125's, as those are definitely unique to those platforms. I won't insert an SNL reference here but was thinking about it, 1313 | ||

>>>If you think you can improve a product always test your changes before you come to rely on them. Yes . . . 1997 M2 Cyclone Lead Engineer Martin D. Brown . . who also questioned Abe's ability. . . albeit briefly. . . found that out at the old AMC test track before a group of AMAZED Showa engineers one day when we were doing some testing. 1313 will recall the amazing details. The very reason I'm always confident that Buells are tested so far beyond what a street rider will ever put them through you can not possibly imagine it. |
