mealexme Posted February 3, 2015 Share Posted February 3, 2015 So, I've ordered a new chain/sprockets due to the old one having lots of kinks in it due to the scottoiler getting blocked up.Those kinks mean that the chain has gotten WAY too tight, to the point where there is no slack, even after loosening the wheel off quite a bit, and I think its been like that for a whileThe question is, what damage could this have caused to various components (other than the chain and sprockets), and how do you check for those issues? I hear it could damage the crankshaft etc?Many thanks Quote Link to comment Share on other sites More sharing options...
Stu Posted February 3, 2015 Share Posted February 3, 2015 Whoever told you it can damage the crank is an idiot Try the output shaft on the gearbox at worse you will kill the bearing You will know if it's gone as it will whine I have never known one to actually fail I wouldn't worry too much Quote Link to comment Share on other sites More sharing options...

Yea, thats the shaft I meant, not the crank Quote Link to comment Share on other sites More sharing options...

I'm hoping its just worn now, rather than the bearings Quote Link to comment Share on other sites More sharing options...
megawatt Posted February 3, 2015 Share Posted February 3, 2015 Keep an eye on oil leakage from the output shaft bearing seal. Don't mistake oil from that area for chain lubricant. If it doesn't leak, you're probably ok. Quote Link to comment Share on other sites More sharing options...

cockercas Posted February 3, 2015 Share Posted February 3, 2015 Dont worry about the clicking. Mine dose it to. Quote Link to comment Share on other sites More sharing options...
mealexme Posted February 3, 2015 Author Share Posted February 3, 2015 sweet, thanks guys. I'll put the new chain on when it gets here, clean up the area, do another sound test then keep checking for oil Quote Link to comment Share on other sites More sharing options...
mealexme Posted February 7, 2015 Author Share Posted February 7, 2015 So, the new chain is on, all lubed up nicely, everything is tightened to spec etc, but I'm still getting the clicking noise. Did it make that noise before?Am I being paranoid?There is no oil as far as I can tell. No evidence of it leaking in the past anyway. I can definitely hear it whilst on the bike, now I'm not wearing earplugs or listening to music, but I'm not sure if I'm just kidding myself into thinking about it, or if that noise was there before and I just didn't notice it. The rear sprocket doesn't make any noise though, which makes me think theres an issueAnyway, heres the vid of the sound.http://i1223.photobucket.com/albums/dd519/mealexme/th_20150206_121849_zps6ybd4pkx.mp4 Quote Link to comment Share on other sites More sharing options...
fullscreenaging Posted February 7, 2015 Share Posted February 7, 2015 You did change the sprockets along with the chain? Quote Link to comment Share on other sites More sharing options...

cockercas Posted February 7, 2015 Share Posted February 7, 2015 Cant watch the video but mine clicks. Its because you are listening for it. I was the same. Quote Link to comment Share on other sites More sharing options...
Mr Fro Posted February 7, 2015 Share Posted February 7, 2015 They can make a bit of noise when they're new - have you made sure the wheel is aligned correctly? That can have a big impact on noise. Quote Link to comment Share on other sites More sharing options...
Stu Posted February 7, 2015 Share Posted February 7, 2015 Its the chain hitting the rubber buffer on the swinger Nothing to worry about! Quote Link to comment Share on other sites More sharing options...
Stu Posted February 7, 2015 Share Posted February 7, 2015 P's Is it as bad turning the other way? And also run it on the paddock stand in 1st and 2nd make sure it doesn't fall off Quote Link to comment Share on other sites More sharing options...
mealexme Posted February 7, 2015 Author Share Posted February 7, 2015 Thanks guys, i hope your right.I'll have another look at it on the stands. I'm fairly sure the wheel is aligned as i reset it and aligned both sides equally when i put the new chain onNow all i need to worry about is the can chain tensioner and front wheel bearing (i have the parts, just need to fit them)Good damn service had eaten all my money Quote Link to comment Share on other sites More sharing options...
mealexme Posted February 9, 2015 Author Share Posted February 9, 2015 so, this noise has REALLY been bugging me recently. It definitely wasn't there before I ran with a knackard (and way, way, WAAAYYYY too tight) chain for months on end. The noise is definitely coming from the sprocket area rather than any guides or anything, but I took the front sprocket off and ran it un-loaded up to "50mph" according to the speedo and volla, no noise. I guess that, combined with the fact there is no oil means its 100% not the bearing, unless it would only make a noise when loaded with the chain attached.Sorry, I get paranoid easily, especially when it comes to my pride, joy and only transport and when it can be something supposedly so expensive to fix that people opt to buy new engines rather than get it fixedAnyway, side note - my YBR used to have a little device on the front wheel to tell how fast it was spinning. Do "newer" bikes have it connected up to the output shaft and work out how fast your going vs which gear your in or something?Or is it just magic? Because I certainly wasn't going 50mph on my ABBA stand! Quote Link to comment Share on other sites More sharing options...
