i just picked up my bike the other day its a 2003 r6 with 15k miles on it i noticed a ticking noise from in the engine. The best way to describe it is it sounds like the ticking noise you hear on a propane grill with the electric starter. the bike runs fine the oil is new and the level is good. the noise isnt really loud but if you listen for it you can hear it. The guy i bought it from said he got the valves checked last year. any thoughts? i am making an appointment on monday to have the valves checked.
