Ehcbr125 Posted December 12, 2020 Posted December 12, 2020 Hi Guys, Wondering if you could help me out. My motorcycle won't roll forwards or backwards freely. It started just backwards but now it forwards too. Do any of you know what this could mean? Thanks in advance Quote
Ian Frog Posted December 12, 2020 Posted December 12, 2020 Pointed question! What was the last thing you changed/ adjusted ? Chain alignment or spacers on the spindle are favourites for this kind of thing. Cheers Ian Quote
Ehcbr125 Posted December 12, 2020 Author Posted December 12, 2020 Hi thanks for your reply. The last thing we had done was the rear tyre changed along with the chain and sprockets. This was done at a garage not by ourselves. It's the same guy we've used for years now with no problems. So really at a loss. Quote
dynax Posted December 12, 2020 Posted December 12, 2020 Chain loose, brake binding, possible clutch issue. Does it roll with the clutch pulled in when in gear, is it in neutral and not slipped into a gear. Should keep you busy for while Quote
Ehcbr125 Posted December 12, 2020 Author Posted December 12, 2020 Would a loose chain really cause this? I dont think it is loose but will check again. I have tried to look up symptoms of a binding break but cant find much as this was our first thought. Will try it in gear with clutch in as we haven't tried that yet. Quote
Ehcbr125 Posted December 12, 2020 Author Posted December 12, 2020 Thank you for your reply too dynax Quote

Copied from google What happens if my motorcycle chain is too loose? A loose chain has the potential of coming off the sprockets altogether. This means you'll lose power to your motorcycle even though the engine is still running. ... Or it's possible for it to jam up in one of the sprockets and cause the motorcycle to abruptly stop. 1 Quote
raesewell Posted December 12, 2020 Posted December 12, 2020 If it's been sitting for a while it might be the brakes are a bit sticky. Quote

One thing I will say that I should of mentioned it that it will move. Almost like pushing it with the back break engaged if that makes sense and after a while it does loosen so it moves more freely if that makes sense Quote
dynax Posted December 12, 2020 Posted December 12, 2020 Is it a drum or disc brake on the rear? Quote

dynax Posted December 12, 2020 Posted December 12, 2020 It might be possible the disc is warped and just enough for it to bind till you force it through. Quote
skyrider Posted December 12, 2020 Posted December 12, 2020 6 minutes ago, raesewell said: Brakes are for stopping breaks are for tea. right again Quote
dynax Posted December 12, 2020 Posted December 12, 2020 Also alignment might be out, after having the work done, doesn't take much for it to be out. Quote
Ehcbr125 Posted December 12, 2020 Author Posted December 12, 2020 Okay, now I can call the garage and know what to tell them to look at. Dad has mentioned the warped disc also so may well get him to come and have a look tomorrow. Is this dangerous do you know? Quote
iangaryprice Posted December 12, 2020 Posted December 12, 2020 There are 2 reasons that could have caused this problem 1. Rear wheel repair not oen correctly. I know you trust hte guy, but everyone can have a bad day. 2. Corrosion has caused something to sieze, common this time of year because there is now salt on the road. Put bike on the centre stand. Raise front wheel clear of the ground and try to rotate it. It should be easy to rotate and continue to rotate after you stop pushing it. If not easy, main culprit lilely ot be the brake, less lilely wheel bearings Repeat with the rear wheel. If either wheel is hard to rotate listen and look at what is happening. Try rocking it back and forth. If the brake is binding there will be no free play, the drag will be fairly constant. If its a drum brake try to move the arm on the backplate, they often sieze into the backplate, after you apply the brake it should be released by the spring, try pressingthe brake pedal and see what happens. You my be able to see which part is sticking. Check there is free play the pedal should move about 10-30mm before the brake is on. Have a look to see the chain is adjusted correctly, should have about 15-30mm play. Check the wheel spindle nut is tight and the adjusters are correctly positioned, Good luck, report back with what you find. 1 Quote

If it is warped depends by how much, but ideally would be better replaced 1 Quote

TimR Posted December 12, 2020 Posted December 12, 2020 (edited) If been ridden in the wet and then brakes could bind .. Give the brake calipers a thwack with a Rubber Mallet/ piece of wood (and same on the brake drum if drum brake ) Also have you made sure its not in gear ? False neutral can illiminate the neutrsl indicator but still be in gear I presume it left their garage fine ? (Check the rear drum torque arm is still connected as if not rear brake will lock on if drum brake) Edited December 12, 2020 by TimR Quote
