Took the primary case off and the primary chain has snapped.
It seems to have eaten the inside of the primary casing too. Have a look at the pictures. I'm thinking I'm going to have to get it written off by the insurers as I don't know how much it will cost to fix and if it has affected any other part of the engine.

Any advise would be grateful

Feck me, it'll take a lot to snap that chain! Had you upgraded the primary tensioner?

What are the chances that it was that snapping which caused your off? The tensioner breaking, getting caught and locking the drive-train and chucking you into the shrubbery.

Not sure that it would have done much to the engine, but maybe the gearbox wouldn't be so happy. That would probably be enough to write it off, if that's what you want.

It's fairly common for the chain to eat the cases a bit but I've never seen one that bad. Never known a triplex primary chain to break either

bit soon to ask but if you do total loss it dont let the bike go and i will pay you the salvage value and a bit more no matter what cat.

Hmmm, that could be cause rather than effect

But it would seem that the chain has been eating the case for a while, that wear hasn't happened in an off, no way, IMO.

This bit of text was rubbish

Was wondering about that but there doesn't seem to be any other marks on the chain, just appears to be one point of failure.

Not that it's very easy to tell from those pix, maybe another closer image of the inside of the primary case and the chain would help.

Still, with the race exhaust and some other rather tasty looking stuff, I'm sure there'll be a queue behind tubbs.

what does the bolt look like could the chain have been to tight as they get tighter when hot is there any other damage where chain could have snagged
