I wish I'd of seen this earlier. It is just the mating call of the wild ULY.

This has got to be one of the better write-ups I've run across for replacing the output shaft bearing without splitting the cases. Really wish I'd found it before I tore mine completely apart a few years ago.

That was very nicely done. That pulley holder is a lot simpler than the one that I made. A lot of well made special tools, what surprised me was all the neat tools carefully machined then the bearing pullers looked like they were hand ground. They worked, that's what counts. Wish I could have done something so simple but I had to split my cases for a bad tranny. Oh well.

I think it's your tranny output bearing. The reason it doesn't make noise in the lower gears is because it takes more rpm to get it to sing. The bearing is brinelled and it's basically the balls running over potholes. As the rpm increases so does the sound. You notice that it's rear wheel rpm related and not engine rpm related.
We overhauled a centrifuge that had bearings 14" in diameter. The new bearings had been sitting in a cabinet for years with the constant vibration of the surrounding equipment. After the overhaul was over we fired it up. Take that sound from your video and multiply it by 100!! You could not stand to be inside that building from all the noise.

I guess it is my turn! As I got to BITA 7, i was hearing a new noise. Described in another forum accurately a sound like a dirt bike knobby tire being run on pavement flat at speed. It got worse as i rode it around the Spruce Pine area. Made it home without incident. Got it out to do a little ride yesterday and noise after five miles turned me back.

The actual output shaft bearing replacement is not a big deal. Have not ordered parts yet. Looks like a couple of hours and four beers!

the above method is only an option for pre-08 years. 08 and up have a different output bearing. Why oh why couldn't Buell have used a trapdoor/cartridge trans like any thoughtful engineer would have?

H-D said structural integrity, everyone else said cost savings.

Buell probably said less parts/fasteners/gaskets/labor/etc

Yeah, this is probably our next step.

Yeah, it's bullshit having something that morphs simple transmission problems into write off the bike problems for the less mechanically inclined.

Sorry to hear you've encountered some issues as well Etennuly.
