clunking noise - 996 bip
This is very strange...anyone else had it?
when the bike isn’t running and is leant over on the left hand side (nearest the curb) when moved forwards or backwards i get a metal sounding clonk. When the bike is upright or leaning on the right hand side=nothing.
Wait it gets weirder
the clonk isn’t set in one place. in other words move the bike forwards (again leaning over on the left) and wait for the clonk. then move it back a bit and move fowards again the same distance. Nothing. Move it a bit more...nothing. bit more again...clonk
it defiantly seems to be coming from the rear of the bike?
the chain seems ok. and doesn’t touch anything
all the carbon bits have been removed
have removed the rear calliper and move the bike whilst friend holds the calliper
rear bearing on the wheel seems fine and feels like there is no signs of wear (using Renthal sprocket carrier and sprocketts)
on the abba frame stand (suspension not loaded)..nothing
on the paddock stand ...nothing
Mike at MDR who services it hasn’t come across such a problem before, especially as the clonking noise doesn’t have a pattern in relation to movement. Says its not the recall forged problem as i would know straight away But without going to town on it (stripping it down) he cant really tell what the problem is. (fair enough)
anyone had this one?
