broony Posted March 8, 2015 Report Share Posted March 8, 2015 Out on the bike today and my C15 was struggling with the mud clogging the front sprocket. Fortunately I don't ride in mud too much but on a few occasions that I do the issue with the front sprocket clogging causes the bike to snatch(chain jumping sprocket??),is there a way off keeping mud out the sprocket.I have an extension on the bottom of the mudguard going past the swingarm pivot.Any ideas?? cheers the noo Brian Quote Link to comment Share on other sites More sharing options...
jon v8 Posted March 8, 2015 Report Share Posted March 8, 2015 Making sure the chainguard goes below the lower chain run and there are no gaps between the mud and chain guards is about all you can do.The guards made and fitted by the previous owner of my AJS look a bit overkill,but I have to do a stupidly muddy trial before the chain picks any up,which is good for gearbox,clutch and chain life on an old banger... 1 Quote Link to comment Share on other sites More sharing options...
old trials fanatic Posted March 8, 2015 Report Share Posted March 8, 2015 I know this is obvious but you do have a decent chain guard fitted ? Could be picking up off the bottom chain run though if mud is deep. Remember to ride through every puddle you can to dilute it ? Sorry cant think of much else Quote Link to comment Share on other sites More sharing options...
the addict Posted March 8, 2015 Report Share Posted March 8, 2015 Would a smaller front sprocket and larger rear sprocket help by providing more room for the mud to escape? Quote Link to comment Share on other sites More sharing options...
totalshell Posted March 8, 2015 Report Share Posted March 8, 2015 if the mucks coming from the chain in the first place the most obvious way to stop it is a chain guard that proper;y protects the chain top and bottome runs as they pass the wheel tyre swing arm .. failing that move to spain.. 2 Quote Link to comment Share on other sites More sharing options...
the addict Posted March 8, 2015 Report Share Posted March 8, 2015 (edited) I mentioned it as my rev3 had the same problem that was greatly helped by going a tooth down on the front and 2-3 larger on the back, removing the front sprocket guard also helped.

kwackerdave1 Posted March 8, 2015 Report Share Posted March 8, 2015 Easy way to stop this. As fitted to my Triumph twin are Montesa chain tubes. I'm afraid they are not Pre65 but they have been fitted for at least 30 years renewed once. Best thing Montesa ever made. Quote Link to comment Share on other sites More sharing options...

Those two changes would make for a significant lowering of the gearing, no? Quote Link to comment Share on other sites More sharing options...

Sorry, my mistake, smaller front and smaller rear lol. 2-3 off the rear makes up for the 1 from the front depending on the teeth numbers.

broony Posted March 9, 2015 Author Report Share Posted March 9, 2015 Think the main problem is my chain guard,time for MK 2.Thanks for the replies. Cheers the noo Brian Quote Link to comment Share on other sites More sharing options...
