stuck clutch (won't disengage)

Post by superhawksarah » Sun Aug 14, 2011 4:27 pm

I finally got my 305 running, but still can't ride it because the clutch won't disengage. I've tried putting it in gear while on the stand, holding in the clutch, and applying the brake. So far all I've managed to do is kill the engine. This bike was running about 7 years ago, but it sat since then. Apparently the clutch plates are stuck together. Does anyone know a simple fix for this? How hard is it to get to the clutch and take it apart? the clutch is also really hard to pull compared to my other bikes. I assumed a dry cable but could there be somethings?

Also, this bike did not have any air cleaners or air horn when I got it. Are the rubber horns and filters still availble?

Lastly, where's a good place to get some tank badges. I'm not concerned about getting exact replicas, I would be happy to get a pair of the all-metal replacements. I'd also like to find a replica toolkit, mine is missing. Again, replica is ok.

When I have a clutch issue with the stuck plates, I get a rolling start and then pop it in gear. The engine won't stall as you're moving along. Try to ride long enough to get the engine warmed up and the clutch plates will usually co operate. Make sure you are in an area where you are not subjected to traffic in the event that the clutch will not disengage. Then change the oil and adjust the clutch.

I tried many different ways to break the plates loose on my 66 Dream, nothing would help so I
just replaced the plates.

Remove the clutch cover (and anything that stops it from coming off like the shift lever).

Undo the 4 clutch bolts evenly and remove all the plates and clean them. Steels will probably be rusty so just wire brush them to get them clean and wash the old sticky oil off the fiber plates. If you choose to replace them, soak them in oil for a while before you fit them.

It's an easy job, but messy and drain the oil first and have a large drip tray or turkey roasting tray to catch oil drips.

thanks guys, I managed to break it loose by riding it around the church parking lot across the street, holding the clutch in, and shifting back and fourth from 1st and 2nd. It only took a few shifts. So it got its maiden voyage around my neighborhood at 7:00 saturday morning (probably to the neighbors dismay!). But the clutch remains to be very stiff, I can barely pull it in. Its way harder than any of my other bikes. I tried lubing the cable, but no noticeable difference, so I guess some exploratory surgery is next. The right side is running rich, so I may be tearing into that carb too. One of my friends told me to run some aviation fuel through it first, so I may try that.
I have two other bikes torn apart right now, so I think I will wait until I get those fixed before I tear something else apart.
But riding it sure takes me back. How cool that was!
5 bikes, and nothing to ride at the moment! argh!

repro badges

Post by jleewebb » Fri Aug 26, 2011 1:50 pm

a quick search for "repro badges" will yield lots of info...mostly pointing toward Ray at RRHByrne@aol.com

not sure where to find the metal badges.

good luck with your clutch, I'll leave advice there to the experts.
