Willy's thread from UKBeg - http://www.ukbeg.com/forum/viewtopic.php?f=7&t=127 51 You will have to forgive us Brits for our idiosyncrasies ... | ||

You'll have to excuse us Brits for Willy as well  (Love ya really Chap  ) | ||

at least he's not writing in capitals or in pink good work though willy, keen to check it out  | ||

Keep us posted on this. Interested in this. | ||

What's the point? | ||

Willy - interesting idea and it looks like you've been busy - two questions? 1) Does your belt drive have a problem that this is intended to fix (like rear wheel bearings)? 2) How will this affect the rear axle torque - or rather, will the axle have to be turned further in to get to specified torque? (my point here being that belt tension and rear axle torque are related) Seems like that would be something to keep an eye on, as too much axle tightening would possibly crush bearing spacer and lead to faster bearing wear - but maybe I'm missing something here....

i appreciate the work going into it, but ive never figured out what they would be useful for? i suppose it would atleast give the driveline a little extra lash... as for over torquing the axle because there is less pressure on the belt... i suppose for someone somehow somewhere that might be a problem?! i personally have never put a torque wrench on any of my buell axles. turn the axle in, snug it, and tighten the pinch bolt... good to go. and i have yet in 8 years and multiple bikes of buelling to ever need to replace a wheel bearing. apparently my "yep... about there" torque method works well... even on the last over head cam i installed about 80,000 miles ago  lol | ||

So, none of you Americans have got a Free Spirits tensioner fitted to your XBs ? In the UK wheel bearings don't tend to last long - the first set on my 1125R only lasted 4K, and I tend to "baby" my bikes. Anything that takes a little tension out of the driveline can't be a bad thing surely ? | ||

> Anything that takes a little tension out of the driveline can't be a bad My guess is it is a trade off. The belt likes a fairly high load/tension, the wheel bearings don't. I remember reading some internet lore a few years ago around the new (at the time of the release of the 1125r) belts and that they are actually *under* what the belt manufacturer wanted in terms of tension. There's no doubt the tension is hard on bearings, though. And, wheels, too, in some cases. Worth what it cost you to hear that. | ||

new vid on you tube ,today we tested my 1125 sprung ideler wheel set up ,a few tweeks sorted vid is 1125 sprung ideler test run 21,1,12 enjoy | ||

I have a friend w/one on an XB. Looks scary; loosing the idler axle or spring would create a big problem. I think the bearing failures have more to do with bearing quality than belt tension. | ||
| Willybuell |
hear in the uk we use SKF or NSK bearing in wheels ,i do between 5 & 7000 miles a year ,two trips to southern irland accounts fof nearly 2000 of those miles ,a very dear friend on mine is ex princepal enginneer from NSK super precision ,hear in newark ,and ASSURERS ME they are not up to the job on our roads and the way we ride ,i use a set in both wheels a year ,so its not a quality problem | ||
| Cycledoc59 |
Ok, but I replace a lot of failed rear wheel bearings in chain-drive sport bikes. I'm not sure, yet, that bearing failures are higher for our belt-drive types.. I do have a set of All-Balls front/rear in stock for my 2 Buells. (same bearing fit both) Ok so far on originals at about 15K miles each. But, after this info, maybe I'll change them... | ||

I guess sometimes practice doesn't match patent... http://www.google.com/patents?vid=USPAT6866112 | ||

There are many reasons to obtain a patent to a design, even if you don't intend to use it. In the course of designing a product, you might develop several novel ways to perform a task, one of which is clearly superior. Even though you only want to use the best solution, you'll still want to patent all of them. Sometimes it's worth the cost of a second patent to make sure your competitor can't use the second-best solution. Doing that widens the technology gap between your product and your competitor's, thereby creating the sought after "economic moat." Not sure that this applies in this situation, but it's a reason that patents wouldn't match production. | ||

Time, I was mostly being facetious. This patent might still apply to the 1125 design. Just because a sprung tensioner moves, doesn't mean the original design wasn't keeping constant tension. The concept behind the original design was that the change in contact between the tensioner circumference and the belt would compensate for changes in driveline length during suspension operation. More than 1 way to skin a cat...and Buell chose the hard one ac |
