Drive Shaft

[Sparky59]

I purchased a used trans from fleabay that suffered that fate.....so i know the pitfalls if the bike was dropped hard on left side and shifter shaft gets punched inward...

YEP, mine was dropped on the left side, bent the dogs for 2nd gear.
Take the clutch springs off and take the oil pan off and inspect, im 75% that you have a damaged trans mostly in the shifter, you are like 80% there to taking the engine out anyways! MORE PICTURES, we love carnage!

Yes looking that way, will give me something to do over the xmas holidays

Update: after taking clutch out I found the thin gear change return spring had popped off, so I have all gears now & no need to split engine. Being a supposedly 09...but is a silver engine that's been painted black (someone did a swap at some stage) I also took the torsion damper off to check if bearing was around the right way & all is good. Cam shims all in spec & no surprises in sump so new gaskets all round & will temporarily put back in the damaged frame for a startup.

SWEET!

Got it up & running
Can't seem to upload a short video...says it's too large? It's only 15 seconds

The torsional damper bearing looks like it's on backwards. The unsealed side of the bearing should be visible in that pic. It gets its oil from an oil hole in case.

I would also check and see if it has a totally sealed bearing on the other end. That was something they did on the later models cuz it didn't get enough splash oil. If it's not a double sealed bearing, I would get one for it. Save you some heartache later.

I could see the torsion bearing in that pic, it was not sealed that side & the other end was double sealed.

The bearing you put the arrow on is currently open to the transmission. That is the early design. They didn't get enough "splash" oil from the trans and would fail. Not sure what year, but they started putting a double sealed bearing in that spot. I've never heard of a double sealed bearing on gear end. It's supposed to be sealed on the side facing the gear, and open on the end that slips into the case. There is a hole there that feeds it oil. Some early rockets had that bearing installed backwards with the sealed end towards the case which effectively isolated it from it's oil supply.
