Invisible_Man Posted November 24, 2014 Share Posted November 24, 2014 Hi, Still on a mission to track down the source of my foot numbing vibrations from the CG125.Looking at the rear sprocket today I noticed quite a lot of side to side movement when pushed and pulled. I realise that there should be some play but how much is too much? The cush driver rubbers where looking a bit eaten when I changed the sprocket earlier this year. Could this be the source of the damn things vibration? Thought I'd ask before buying parts unnecessarily. Cheers, IM Quote Link to comment Share on other sites More sharing options...
Stu Posted November 24, 2014 Share Posted November 24, 2014 you shouldn't have any side to side movement!! check all your spacers and axle tightness cush drive rubbers is for back and forth to take the shock out when the chain pulls tight or you let off the throttle Quote Link to comment Share on other sites More sharing options...
Invisible_Man Posted November 24, 2014 Author Share Posted November 24, 2014 Hey, Cheers. I'll order some new ones. There is quite a bit of the play! Rear wheel is solid so I'm assuming the bearings OK. Bikes never been the same since I took my old man pillion and then towed his bike home. I'm thinking the jolts knackered the cush bushes.

Stu Posted November 24, 2014 Share Posted November 24, 2014 if the sprocket is moving side to side its not the cush drive are you supposed to have a spacer between the sprocket carrier and wheel? my TL used to and it slotted between the bearings in the wheel and sprocket carrier Quote Link to comment Share on other sites More sharing options...
Invisible_Man Posted November 24, 2014 Author Share Posted November 24, 2014 Hi, Definitely all there. It used to run smooth as a sewing machine, even more so after I replaced the sprocket. It's not much work to strip the back end down and check everything.Cheers, IM Quote Link to comment Share on other sites More sharing options...
MarkW Posted November 26, 2014 Share Posted November 26, 2014 I'd be interested if you find what the problem is. It's been five weeks since I got back from a 1600-mile round trip to Basel, and I've still got pins and needles in the ball and toes of my right foot. The vibrations through the right foot-peg were pretty painful on the last bit of the journey, so I reckon I've probably done some nerve damage. Haven't found the culprit yet...

Invisible_Man Posted November 27, 2014 Author Share Posted November 27, 2014 Hi Mark Sorry to hear that! Hope it clears up! Thankfully I haven't done quite that many miles on it so my numb feet usually feel better after a day or two rest! Still its bloody annoying having to sit on something that feels like it's vibrating like a sonic bath! It' been a problem since i towed my old man and his bike 15 miles home when it broke down. I'm thinking the strain has done some damage somewhere... It's just finding out where! Going to strip the back end off at the weekend and what I have the oil out have a look at the clutch and other easily accessible internals. If that doesn't fix it then it's time I flogged the bloody thing. Will let you know the outcome. IM Quote Link to comment Share on other sites More sharing options...
pointblank0 Posted November 28, 2014 Share Posted November 28, 2014 Does your bike have a rear drum brake? Only asking as I had a similar issue with an SR125 many years ago and it turned out to be a worn hub. Had to buy a new wheel. Quote Link to comment Share on other sites More sharing options...
Invisible_Man Posted November 29, 2014 Author Share Posted November 29, 2014 Hi,It does. Funnily enough i have had the occasional weird noise from the drum....like something popping. Tonight i stripped the clutch and rebuilt it using another CG engine i had. Seemed to cut the vibes in half....Psychological probably lol Tomorrow i'm going to strip the back end out and have a look at the bearings, cush drive etc. Thanks for the heads up on the drum. I shall be checking this also now. Cheers,IM Quote Link to comment Share on other sites More sharing options...
