I have a few questions that I am not too sure should concern me.
I have a katana 600 post. I just bought it used with about 17k on it. When I start the bike, it makes a pinging sound that I think is the valves. It is coming from the left most side at the top of the engine. It is only on one side, so I don't think that is normal. The noise is faint and definately not a knocking sound. It seems to only be audible at around 1-2k. After I rev it, I can't hear it. Is this something I should worry about?
I also smelled the oil and it smells a bit abnormal. It has a sweet smell to it. There is no metal in the oil, no gas smell. It looks like it is close to new. It just has a kind of sweet smell. There are no streaks of coolant ( I don't know why an oil cooled engine would). Is there something that a shady seller could put in it to quiet the engine or something that would have that smell?
The last problem is the idle. It seems o idle a little high after being warmed up. It goes to 3k. I was playing with the idle adjustment, so I don't now if that was me. When I turn the adjustment slightly, it goes back to 1100.
The reason I am so concerned is that the guy I bought the bike from seemed shady. I want to have a mechanic look at it, but I would rather have an idea of what it might be before going in. The bike rev to the redline. It has no loss of power. It shifts perfectly. Other than the pinging, there is no other noise. The exhaust sounds great. I did spray some water on the exhaust headers and the one on the left most side evaporated slightly slower than the others. This was a fraction of a second difference. My dad heard the sound and thought it might be a connecting rod, but it is coming from the very top of the engine and he has not rode a bike since the 80's. How can I get a diagram of the entire engine? I think would help me if i take it apart.
