    Hey guys.

    Got a bit of a problem with the old steamer. I think I've knackered the sprag clutch. It's a 96 Tiger. Makes a nasty noise when trying to start. Sounds like a bag of ball bearings in a cement mixer. I've had the starter motor off and it's got all it's teeth. The sprocket it meshes with also looks good. Can't find anything metallic in the oil. Unfortunately I don't have the removable plate to get the the sprag. Is there a way to diagnose the problem with the engine in the frame or will I need the engine out ?

    I read somewhere there is a spring that fails but it's not a part you can order. You have to have the whole clutch assembly at £££££'s :(

    Any advice would be welcome.

    Wow, that's much easier than fixing the spray clutch on my Laverda ! It had 7 individual springs, one behind each roller !

    If you need help in doing the job (engine out) Clive Woods t3 masterclasses could be a great help. He strips a motor down to the spray and also strips the spray showing you all you need to know.

    That's some great info. Thanks guys.
    Unfortunately it is going to be the crank case split to repair but at least I can find a replacement spring for the clutch. Just need to read up and check gaskets/seals required etc and clear a space on the bench. (Think that might be the biggest job :D ). Fingers crossed I don't find anything else on strip down....

    If you are happy to go ahead with the job remember no need to take the clutch apart to split the cases. Myself I would fit a new sprag. All the effort to take it apart I wouldn't want to take the risk.

    I have been thinking along the same lines. I'm not sure how long I intend to keep the bike. I have been thinking of getting it going again then putting it on the market. Obviously a new sprag clutch would be a winner for a new owner, but not sure if I want to chuck another wad of cash at a bike I may not be running long. I think I'll break it down, evaluate the sprag, clean everything up, throw a can of paint at the plastics and give the lump a good clean then rebuild. Should look a lot better than at present. (It's not currently very pretty :) )
