Shuddering when shutting throttle?

Discussion in 'Technical and Troubleshooting Torque' at netrider.net.au started by julz, Mar 1, 2010.

  1. Hello,

    Bike - Honda CBR250RR 1990 30K

    Any suggestions would be helpful! :-({|=

    Whats happening is when i shut the throttle say coming to a stop, i will get a shuddering that im pretty sure is either gear related or chain related. The higher the revs the worse it is.

    I get this similar shuddering if it plays up putting it in a gear and will be iffy unless i change gear and goes in properly. Does this make sense?
  2. Could be a cush drive or a clutch on the way out.
  3. Thanks for the reply, i just had a look at the chain and it looks very loose and dirty and has kinks in it. I lube it but i think its just finished. I might replace the chain first and if still happens ill check your suggestion.

  4. Chain and sprockets
  5. Sounds like a good plan. Change the front sprocket too as they are usually only worth about $20. Have a good look at the rear one too.
  6. I changed the chain and sprokets and problems gone, so all those that read this thread ;)
