I have a C90T 2006 while reading a lot of post it seems there is a lot of you with valve noise please check your fule door lock there might be some play in it small pice of tape on flange cured the ticking.
i got this ticking noise coming from the engine even with idle and it goes so loud that i cant ride faster than 60 mph.
the agency is of no help. given the bike for repairs so many times. they say its normal.
i want to try the flange trick but im a newbie with very little technical know how. pictures or a little more description would be cool.....
