I got this 1965 Yamaha 305 this week for fun. It is very original and in nice shape. I always liked these . My brother had a 305 Hawk and a few guys he knew had these. It runs nicely but taking off as I am engaging the clutch ( letting it out ) there is a clunk. Once the clutch has been let out fully it is fine and smooth and goes through all the gears including first easily. I think there is a clutch problem and not transmission but, what do I know? I did receive a complete other clutch assembly with it so I would prefer it to be clutch. What do you guys think?  |

Is this the one that was listed for $3200 in the Niagara area Dave?
I would pull the cover off and have a look.
Could be something simple.Most Japanese clutches are very similar . I think it wouldn't be an issue sorting it out .

Clutch hub loose on the input shaft? Hub splines worn?
Sprocket loose or worn splines of output shaft?

Thanks Ian and Scott. I am going to put it up on the lift and have a look. I am hoping that it is a clutch thing and not a tranny shaft. And, yes Ian, it is the one from Niagara. I got it for much less and he included close to $1000 in extra parts, most of them new.

I checked the easy part first and see that the front sprocket is worn, pointy and tilted teeth. I have ordered another one but wonder if it could be the new chain binding on the crappy sprocket? It would be nice if it was that simple.

The guy said he had better offers but I was the only one to offer and then offer to send a deposit right away. It is actually a sweet bike. Runs pretty well and I got lots of spare parts including a whole clutch assembly.

My first bike was the 250 same Color.
I hope it is the sprocket. The clutch will be hard to find. I bought one from Barnett a few years ago,they only had two.Turns out they were made wrong.I had to shave the corks down to make it work.Early clutches had 4 plates later had five ( or was it 3 and 4 im getting old) if some one mixed them up your problem could be there. They always did clunk a little going into first because the clutch is on the crank and turning the same speed. Great bikes and hard to kill. I put a million miles on mine flat on the tank at 85 mph. The 305 should just touch the ton. Wish I had it. I think I still have some wheels sprockets and a frame here somewhere.also the manual I got with mine in 1968.
Hope this helps

These are a different clutch. The fingers on the plates go in as opposed to out like other clutches.they fit over a cogged wheel. Maybe the key way is getting worn.
If it’s the trans the cases split vertical so your work is cut out for you but there is a shift mechanism you can get at on the bottom of the engine,
