question about engine noise
Thanks for all the advise you guys have given me. Ive got a new question. So I havent really ridden this bike yet, still going over everything. So when I start her up she sounds great nice and smooth. After she gets warm, and I give it a little rev I get what sounds like a clicking sound toward the front of the bike. I dont know ANYTHING about bikes but if it were a car I would say a lifter sound...How do I check the oil level? When I start it the sight glass empties and then when warm it fills back up? Any thoughts?

Might be
Might be the valves. Earlier last month I took my bike to the Ducati dealer for a preseason inspection and asked about valve adjustment. The Ducati dealer said to me "clicking or loud taping noise consistence with the revving is a sign of the valves needing adjustment". I didn't need anything done but it was good peace of mind.

Does it just do it at idle or throughout the rev range?
Without hearing it the noise could also be an exhaust leak or just the carb slides bouncing around.
Also with .012" clearance on the exhaust valves, they can "tick" a bit also, Does it do it more when it is cold or when it is hot?
To check the oil level the bike needs to be not running and should be between the lines on the sight glass.

We are are guessing here, take it to a dealer or get a experienced guy over. To prevent more damage stop running it. If lashing is needed that is not too expensive and can be done at home. If it's major I have a all stock running motor about to be up for grabs.

If it's only doing it when warm, it's very likely a loose valve (too much lash). But like 8541Hawk said, a slight exhaust leak can sound just like a loose valve.
With it running and warm, use a long bladed screwdriver (2' or so) to isolate the noise. Put the tip of the screwdriver blade on the valve cover. It acts like a stethoscope with your ear pressed to the end of the handle.

The terms "loose valves" and "tight valves" refer to valve adjustment. It would mean you need a valve adjustment. Having a loose valve is better than having a tight valve, which you would not hear. And a tight valve will cause the valve to burn.
If you don't have a somewhat high level of mechanical skills, shim type adjustment (which our bikes have) is best left to a qualified technician. But even if you take it to a shop, get some references first. There are a lot of hacks out there charging $50 to $85 an hour for lousy work.

When was the last oil change? do you have mcc't? might be a leak from the combustion chamber to the water jacket. This could be the cause of leak, as for heaing a taping sound that is the puzzing part. or Bad water pump, before the bike get up to 160 the thero doesnt open putting more presure on the pump causing it to keeping quite. but once the presure is released the pump makes noise. these are all guesses. Your going to need someone to dig into it before it gets worst or drive it until whats making the noise flys out the side of your engine. JK, dont do that.

If you do it right, valve adjustment could be a 20-30 thous+ maintenance item, or it could be 5-10 thous if one or more is set at one under spec. Hope you can find someone in your area to help you. There are threads herein that can assist someone with a little mechanical ability.

And the screwdriver method I mentioned above will help locate the source of the noise. It can be used on the water pump as well.
Good thing our bikes don't have a dry clutch.

eliminate a lot of the stress and second guessing by replacing or adjusting the CCTs, checking valve adjustment, TPS, and basic carb settings, filters, fluids, and plugs, RR, etc., so that you have a good idea of what you have and what you might be dealing with in the future. Not a good idea to just ride it and wait to find out what's gonna happen the hard way.

So I've got an update..Putted my bike around today..Put about 3 miles on it, not wanting to cause any damage...The clicking noise went away?? came back a time or two but for the most part its gone...Does anyone think that it may have been caused by the shitty gas that was in her that was just burning out?? No weeping either..Any thoughts?
