engine rattle

[kc34]

Guys could be in trouble. The @ has being running sweet for a while now, but over the last 2 days there is one hell of a thump out the engine. I thought it might be the can echoing of theboxes... i took the panniers off tonight and its still there. I can feel vibrations through the whole bike and its worrying. Its getting near the longest day and i dont want to miss out. any suggestions so i might get to the root of it. thanks

Get a large screwdriver and carefully place the metal end on different parts of the engine / bike whilst putting your ear against the handle. It acts like a stethoscope . I have found many a worn bearing, noisy tappets etc this way.

DO NOT PUT THE SCREWDRIVER ON MOVING PARTS .

P.S. I can not accept liability for any damage anybody does to their head whilst performing this operation.

Check for a spark at all 4 plugs if a ht lead has gone to one cilynder it will be dragging the other. or put the bike on a stand in gear (not running )turn the rear wheel by hand then feel-listen this should give you a feel -if its all turning freely good at least its not a metel problem and as im'e shiiite at elecwizardry i walk away. good luck!!

Throw us a bone. Top..bottom...left or right side. Do you hear it at
idle or at speed...or both. Year, model and milage is good to know too.

Lads thanks for your suggestions and help. As yet i have not done a lot about the rattle. The owner of my local bike shop took the twin out for a quick spin last night, and he reckons the teeth on the front sprocket could be hooked. The weather over is here is brutal at the moment so I did not get a chance to take the cover off. There's a chance the chain and sprockets could be shot altogether. Its a geuine honda chain and sprockets with 13300 miles on' does'nt seem much. anyhow thanks again
