Hi,

I've seen a post regarding my symptoms but can't find it again.

See left for engine.

Symptoms; every so often on idle the engine sounds like its 'knocking', if the clutch is depressed the noise disappears.

ideas??

Throttle bodies out of balance. Do a search for my posts on balancing R1 carbs - the process is very similar.

might not be the same but on my vtr1000 bike i get the same thing, took it to the honda dealer as i thought something was wrong but its just the clutch basket and plates making the noise which is normal

I sometimes get something very similar on my carbed R1 - a quick blip of the throttle when in neutral seems to help. I don't think its particularly unusual from what I have seen/heard on this forum.

i have had this happen, but only heard it since i put on my quiet can.

have you ever heard an R1 in bike forrm at the lights - they sound like a bag of spanners lol
