Just for info, this is what my clutch bushing looked like at 7440 miles: And the result... I think, I haven't installed the new one yet. We'll see if that wobble is gone. "Problem screen" looked fine:
Good to see your screen is fine. My new one is at around 2500 miles and, given my luck last time, I'm thinking I want to check it for peace of mind.
So the spring retainer thingies. Not totally hammered, but definitely something that requires attention. And unfortunately, unless they are in really bad shape it is hard to see how good or bad they are until you take things apart. I lucked out and got a set when I bought the bike last year, because from what I understand, Dan is out and isn't planning on making a new batch. Old vs. new:
A rear wheel cush hub is the fix. The springs aren't engineered to handle the power pulses on hard surface riding. Don't forget that the hardened washers wear on the soft aluminum clutch basket too. The stock spring spacers would live a long life just like your transmission gears and bearings will with a cush hub. I have no dog in the fight. Good luck
I replaced the basket bushing at ~8k miles, but I'm at over 15k miles on the stock spring spacers, they're still holding up, and I do not ride gently. I've got a set of the new beefy ones to replace them with, probably this winter.
Mine wobbled like yours: After having replaced that bushing, the wobble vanished. True: take a look at this.
