When I ride there is s distinct change in the pitch of the engine. The change starts at around 3300 or 3400 RPM peaks at 3500 RPM and then returns to normal somewhere around 3600 RPM. Other than this the sound of the engine is normal and very smooth. The bike has approximately 100,000 Km on it (1995 K75RT). This happens no matter what gear I am in and the change is always in the same range of RPM.
I thought it was related to the valves. I spoke to the original owner and he said he noticed the same thing during his ownership so it has been going on for some time now. He suggested it may be the cam chain tensioner but not sure.
Any thoughts on what could cause this or if it is something I should be worried about?
