Thanks for tips guys. Still pouring down here so i havent got out to check wheel alignment and such..


I have googled cam chain noise and i cant say that i recognise anything. When stationary everything sounds/feels normal to me..


Speed or gear make no difference. Problem occurs in all gears, all speed, but only in this 2000 ish low rev range when using throttle.. When just gliding (cant come up with a more suitable word) there is no sign of it.

ok lets try and think logically about all this.........i know certain peeps think that is beyond my capabilities ( ya know who you are :lol :lol )

• only occurs at 2000 rpm......is that under load only ( moving) or at idle and revs held at 2000?
  
• when you say gliding.......do you mean pulling in the clutch and just coasting along?
  

if answer to revs is under load only, then that points at carb balance or possibly sticking carb slider (s)...te amount of movement on the sliders when revved stationary is minimal
ifanswer to gliding is yes, then a clutch issue to be to blame. also bear in mind, when bike is accelerating, top run of chain is under the most tension, and the reverse as you shut down throttle ( engine braking ) pulling in clutch and holding it in cancels out both. hth a licle bit
