Thrown chain advice?

Sometimes shit happens!!

Think you were with us Dale when my bike threw its rear sprocket? For some reason it sheared a couple of bolts which had only just been checked & tightened.

Hope you've got away with minimal damage

Chain guide Noobs,where is it?It's a hardcase bit of gear but they work.Still,a well placed log or rock will flick a chain easy.

I had a chain jump the sprockets on an old z650, it actually bent the swing arm somehow... might be a problem if yours is alloy!

no chain guide... bad idea... Did it break off? cos that could cause the derailment... Or was it not on before the derailment?

it could have been wheel misalignment.
the chain tension was fine sunday morning, so it must have stretched a fair bit.
the chain is a regina o ring. it cost $180
the front sprocket is a factory yamaha YZ125. and the rear is a jtc gasgas...

as for the rear chain guide, the bike has never had one. it was as it is now when i got the bike, guideless.

Fit a guide before you break your cases fool........

So? how far did the bike throw the chain? was it a good throw or not? sounds abit like a spoilt child throwing the toys out of its cot. But guess you won't come back with a sensible answer.................

I arrived at the trail blazer on Sunday - went to pay -took bike off trailer and went to open fuel tap - HELLO _ only 7 teeth on my front sprocket (Out of 14)? 5 mins of swearing. I then tightened the chain and went on the middle trail - followed by flyingCR250. Amazingly i made it around, then I got really cocky and did the long trail and then came back and did 2 middle and 2 shorts. I felt the chain jump a tooth twice throughout the day. At least i got my 40 bucksworth.Utterly amazed that I could carry on though.
Get a chain guide noobi - end of chain throwing rigmarol.

not far enough it would seem, as your still here to be useless

ill probably just make a chain guide, and use 2 universal rollers instead of a moulded slider piece.
