Well a perfectly good run out ruined by a snapped chain! i Snag is i 'have a track day booked for Friday so need to remedy the situation as quickly as possible. Am i right in thinking i can remove the sprocket without removing the axle nut? i don't have a centre stand or a paddock stand so will really struggle if i need to remove the wheel or Axle nuts. Finally, i see this as an opportunity to go up a couple of teeth on the back, anyone recommend where i can get one from pretty quickly? Thanks peeps!
Bloody unlucky, very rarely hear of a snapped chain, I had one come apart at the hairpin at Mallory on an rgv 250 broke the engine, dropped the bike off at a mechanics house who was going to fix it up, next thing a phone call from said mechanic I need to collect the bike as his Mrs has chucked him out the house turned out he had hit her on a night out in front of everyone, so collected bike and sold it to mate who sold it at rufforth autojumble, that was my racing career over as was the mechanics marriage... Count yourself lucky chain snapping is very bad, hope you get sorted
I got mine here with a larger rear sprocket but it's three day shipping: http://www.carpimoto.com/en-GB/46592_DU-1252-2-DID-530ZVM-X-Chain-15.htm
You do, but I can’t remember if you can leave the wheel on and for it to take the pressure of being on the sidestand. Pretty sure wheel stayed on when I did mine, but it was on centre stand so no side pressure
Hahaha! Yeah JUST undo the 55mm nut that holds the carrier on! I've just broken two / bent three tools getting mine off including gas torch application and a 1.5m extention pipe. Useful tip - Draper Expert 18" breaker bar doesn't flex which is absolutely essential and wish I'd bought it yesterday ....
Agree with others, you 100% need the main 55mm nut off to get the carrier off. Use a rattle gun to spin the nut off. Did the chain damage crank case, swing arm etc? Mine broke 2 years back and wrecked everything on the way out. That rear sprocket looks a bit fecked , how many more did chain have on it? Good luck
The longer bars end up flexing. The two foot one I had snapped at the knuckle after it was about 20 degrees of push. Knowing from experience that it need a pipe extention the 18" yet solid bar made sense.
Mine snapped on the KTM last month. Damaged loads of plastics and dented the exhausts. If I had a track day, I’d just whack a chain on and do sprockets after.
How many miles on the chain ? I have had the rollers break up on a chain on mine, but it was over 20k miles old, and had stretched a lot in the last 1k miles. Take the front sprocket cover off and check for damage, if there is any then i would suggest dealing with that first. that saves having to get into changing the rear sprocket straight away. To swap the rear sprocket you can do it with the wheel in place. Undo the central nut, and then you need a spanner and Allen key to undo each of the 6 cush bolts. Make sure you put the new sprocket on the right way around, its easy to get this wrong.
Thanks for all the replies, chain has done about 12k miles wasn't over tight but last time I checked it for damage was about 1k miles ago. There's no discernible damage to anything and it sounds like the quickest way to get back up and running is std chain and sprocket. Worst case i change the chain over for Friday and sort the sprocket out afterwards. Props to the AA today who were fantastic getting me and the bike home quickly.
