I have a problem with my K1200S (2005), that i would like to solve.
My bike is quite vibey/buzzy above 4000rpm, i can feel it in the footpegs and the seat the most.
I am sure it is the engine.
I have changed a lot of parts on the bike - new clutch basket (K1300S model), airbox also from a K1300S,
new spark plugs, a set of coils, new cam chain tensioner.
I can feel the buzzing even in neutral if i rev it high enough.
What could be the problem? Maybe valves? Maybe the balance shafts?
Or is this normal? I have had a lot of bikes, but none of them were so buzzy.
Need some advice
