So i picked up a 76 with 29 on it for $300, I got it running and have a tick, now i took off the side cover to find this, what do you think the cause could be?
bent rod
Is it okay that it pulls out?
Pics of the $300 buy
Thanks guys for any input-Eric

Could be an oversized sprocket was used (looks like it) and the PO bent the rod out of the way. I say bent because there are no gash marks on it. Also, the originals were 2 pieces not one. The sprocket on there now looks much larger than stock.

Was the chain touching the rod before you removed the chain? if not I'd say it maybe threw a chain In the past and bent the rod. Since the rod is able to spin, the bent part was contacting the chain. Order the one piece clutch rod and a new seal from mikesxs (~$20) and get rolling.

Ya I counted the teeth (17) but that doesnt mean the PO didnt change the gearing once in its lifetime. Considering its a one piece rod vs two , to me that would mean someone did some mods.
Like Earz said, for roughly 20 bucks it would be a non issue.

Excessive slack or a popped chain. Get the replacement from Mikes along with a seal and bushing. Tips for replacement in the vault or on Mikes site under Tech Tips.
Nice Bike.

That looks like an awfully clean bend. Not like it was hit by a chain ...
Anyway, get a stainless steel rod of the right diameter from ho depot and cut it ...
Cool.

I took the the rod out of my other bike and slid it in this one, Should i beabble to compress the clutch buy hand without the bike running? Because i cant..

Yes you should be able to disengage the clutch without the motor running.
If you can't the clutch plates are probably frozen together. Not uncommon for these bikes when left parked extended periods. Rocking it back and forth usually releases them. I don't think you could bend the rod with the mechanical leverage provided with the stock set up. Maybe a hydraulic unit.
I believe for the 18T conversion the shift shaft guard has to be removed. On yours it is still in place and bent down at the front. You may want to look at the rachet. If the plastic threaded barrel is cracked you will lose leverage. If the chain did whack it the indentions that keep the ball in place (in the rachet) may be altered allowing the ball to fall out.

Wow that's a new one,My bet is the countershaft nut came off, got any pics of the inside of the cover? I would get on that motor with some engine cleaner and inspect it really good,check for cracks hairline fractures et. The ticking could just be the need for a cam chain adjustment.I think you got a really good deal $300 nice(I never get such great deals). I assume your gonna tear her all down considering it looks like you got a head gasket and base gasket leak and she's worth putting some time and money into.

Follow the center line from the rod to the tip and you will find they line up. The tip will stay in one place if the rod is spun. This was done for a reason............try putting the old rod in and see if that helps..........if rocking doesn't get any results.

If it was bent by the cahin or sproket, why is it bent back straight.
Cool.

I think chain. Regarding Siranth's above, isn't the shaft supported on the outboard end by the case? IMHO, Gary

I dont believe it sinks in that clutch cam receptacle that far ... I should look at mine, after I clean all the crap off ...
Cool.
