Chain came off
 

Hello all spent the last 3 weeks doing everything up on my curvy sk1 shebruns nice just had the chain come off whilst I was riding just jumped out of gear and wouldn't go pulled the bike up theres doesnt seem to be any damage which is lucky but theres a small leak of clear liquid dont no if its oil or just grime what's the best method to see if theres any internal damage was only doing 15mph and the chain link has come out it's still in 1 piece not snapped in half

Re: Chain came off
 

15 mph - I was going quite a bit faster than that when I lost mine.
I think you'll be fine. Can you still select gears etc. Push it forwards and backwards?

I broke the chain, gear selector rod, and spring. Plus the rear plastics collected a couple more battle scars.

Where is this leak coming from?

Re: Chain came off
 

youve been very lucky as at speed it could have been horrendous. Was it a rivetted link or circlip type? Does it still change gear ok (as far as you can tell without a chain of course)? Need to identify liquid as grime is not normally clear so it can only be oil or coolant.....

Re: Chain came off
 

Hi yes I can still change gear bit awkwardly tho still goes into neutral had to push it a fair hike back .. it's going into the garage friday so they will spot any damage I'm just glad it happened at 15 and not on the motorway could of died .

Re: Chain came off
 

Sorry think it was riveted as the tiny pin has gone out of 2 links but the chains in one piece

Re: Chain came off
 

If it has left two links with no pin and no side plate it was probably a spring clip as it would be strange for both riveted pins to come out.

Re: Chain came off
 

As I suspected it must almost certainly have been a clip link so youve learnt the same valuable lesson I did a few years ago (fortunately also without injury). Never, ever use these except, if necessary, to go a short distance to a mechanic to get a rivet link put in!

Re: Chain came off
 

And even then make sure the open end of spring ciip is the trailing end as the chain travels in the correct direction.

Re: Chain came off
 

Fingers crossed you get off as lightly as I did when the garage take a look.

I was on a dual carriageway - doing about 80 - honest officer.
So yes I did feel quite thankful at the time. I never did find the chain, only broken bits of it later when I was taking things apart. I was aware of not using split links, but that day I also learnt don't buy cheap (ish) chains.

Not so thankful after the 4 hour, 12 mile push though.

Did the chain break then???

Re: Chain came off
 

My bike has done over 21100 miles and the sprocket and chain have been jumping, so last week I bit the bullet and got the garage to source and fit a new sprocket and chain set. Parts £102 plus 2 hours labour
plus VAT of course. The labour included working on a jammed gearbox and binding front brake.

Re: Chain came off
 

wow you got bigger ones than me! Id be poopin if I had a chain jumping plus it doesnt do the rest of the drive train much good as it increases wear on the cush drive and gearbox bearings. To keep costs down I spent a little on a chain breaker/rivetter and change my own chains very easily....

Re: Chain came off
 

Mine, yeah.
This was all I had left.

Re: Chain came off
 

It would jump on hard acceleration. I knew the sprocket was wearing and was going to get it changed at its next service in September as it wasn't too bad. However, I think the chain was stretching too which meant it was happening more often. I was OK with paying my mate at his garage to do it for me as I am totally useless at anything mechanical (I spent all my working life in offices). I'm pretty sure that they spent more than the 2 hours labour I was charged.

Re: Chain came off
 

I had a side plate break on my Z400. Luckily in town and at low speed so all that happened was lots of clanking and a very jerky feel. Looking at the broken side plate it seems like a crack had been developing for a while before letting go, then when it broke the other side bent leaving the two pins splayed out. Lucky I only had to go a couple of miles to a friendly dealer who fitted a spring link for me as a temporary measure.

Re: Chain came off
 

Probably the shock of the loose chain on the sprockets finished it off when its skipped.
