Disaster!

Well not quite but im not best pleased.

Riding up past asda tonight into brighouse (big hill) i got to the top and was going slow due to not having a lot of fuel (wanted to get to shell to treat it to some potimax) anyhow all of a sudden BANG looked down and the chains come off. Balls!!!! now at this point ive also discovered that the front braked stuck on! great stuff. So ive just pushed my bike the best part of 5 miles home and im a little sweaty and ****ed! So having a look the chains snapped!!! also theres nothing to the clutch (feels loose)

Sooooooo Any ideas on how to get it fixed? YC?

Was really looking forward to a new years day rideout Feel ****ed off! Even have half day tomorrow! big wobbily donkey ****!

Well, no clutch suggests the flailing chaing took out the worm drive that operates the clutch plates. Get the front sprocket cover off (3 x 8mm bolts I think, or is it 10mm?) and have a look.

Chain done too tight?

Having the chain flapping around is likely to of damaged things a little. Suspect the worm drive as Matt suggests, but also check the engine casing as this could of been cracked. Check the oil level before you think about starting the bike too, just in case.

To get it running again, sort the clutch (remove front sprocket cover - 3 bolts on a pointy) to look for damage, repair what you see. Then replace the chain (and might as well do the sprockets too).

Think yourself lucky, as flapping chains have destroyed sprocket covers before now, and ripped through trouser legs etc!

feck. its snapped the work drive thingy.

is this an easy thing to replace? I can see ££ signs in YC's eyes

The worm drive is easy to replace, again, talking from experience of pointies, you're looking at 2 bolts to remove it. Then detach the clutch cable, and bin the worm drive.

Fitting is reverse of that, but also ensuring the adjuster & lock nut is ok as per the Gospel of Mr. Squid (clutch adjustment sermon).

Check the push-rod (metal bar at the back of the worm drive) as well for damage, including bending.

cool.

wheres the best place to get one from?

Also how would you fit a chain without a chain riviting tool?

I've never bought one, so I don't know unfortunately. The usual parts places should be fine though.

As for fitting a chain without a chain riveter, well, you don't really. An impact gun comes in handy for the front sprocket too, but it's essential. Take it to a garage. If I buy a chain & sprocket set, it costs something around £100. My 'local' place then charges £25 to fit said kit.

couple of pics. you can see the snapped link in one and its damaged the thread on the rear sprocket.


Im starting to think im a lucky boy actually. I would have normally be caining it up there. Might not have come off so lightly.

Lucky it didn't go through the cases or your leg.

Easy enough to sort. www.bandcexpress.co.uk are good for C+S kits, use tsubaki O ring chain and JT sprockets.

Done similar, overtaking at 90mph up a hill on the M62. The chain didn't snap but it came off the sprockets. I knew it was loose - didn't think it was that loose . I was just about to get it serviced so hadn't adjusted it. Spent 4 hours waiting for the AA man - fortunately it was the middle of summer so I roasted rather than froze.

On a pointy there's some electrical cables down there, which were cut by the chain. The dealer who repaired it said there was only just enough cable left to solder a repair to. And it took out the clutch bits and pieces previously mentioned too. Large repair bill but you expect that from dealers.
