I sometimes have upperend noise while idling, a tick tick tick noise, then gradually fades to a less noticeable sound. The bike has, 3,800 miles on it and had sat for a few years prior to my buying. I'm sure the valves have never been re-ajusted after the periodic mantinace chart schduleing. What might help this problem. The bike does run very good but I don't want to have any engine problems. Thanks...
Re: I sometimes have upperend noise while idling, a tick...
Have the valves adjusted. A ticking sound on the top end is almost always the valves tapping. I slight ticking sound is normal but if it's been sitting for a while it's good to have them measured anyway.

Valves and tappets make that sound when not getting enough oil. When you drive there's more oil pressure and the valves/tappets get enough oil. Of course road noise could be drowning out the sound and the valve noise could still be there.
They are a bit noisy sometimes, hopefully it's nothing serious, good solid bikes those so you should be good.
Check you have the correct oil in there, if your running a thin oil, it may increase the noise and wearing.
Try this, when its parked up and idling cold (when you start it up in the morning) get a screwdriver or somthing similar place the metal part of the screwdriver on the engine where you think the noise is coming from, then put your ear on the handle, doing this you will be able to pin point exactly where the noise is coming from buy moving the screwdriver around the casting also you can really hear her tick.
do it again when she's hot noting the difference of any. If it continues to get noisier, strip her down and have a look in there, could be just the tensioner/guides.
good luck
THE TICKING NOISE IS VALVE LIFTERS.MOST OF THE TIME WHEN ENGINE OIL GETS DIRTY NEEDS OIL CHANGE.DIRT GETS IN LIFTERS THEN CAUSES THEM TO BE NOISEY.IF LIFTERS STAY NOISEY ALL THE TIME.THEY OR WORN AND NEED REPLACING.ITS NORMAL FOR CAR TO SMOKE A LITTLE WHITE SMOKE IN MORNING ON START UP.LONG AS IT DONT KEEP SMOKING IF SO.YOU HAVE HEAD GASKET LEAKING.
new engines burn oil until the rings wear in, if you were riding it hard and never noticed oil gone , possible damage. i would top up oil and keep and eye. if its still under warranty i would suggest dealer look at it
Is there any area on the bike that is covered with what seems to be "wet dirt"? It is entirely possible you could have a blown seal and are therefore dumping oil. If the dipstick is showing nothing, there is not enough oil for the engine and it will seize so don't run it until you locate the source of the leak.
Unless the bike has constant white or bluish-gray smoke coming out of the exhaust all the time, it's not burning oil.
The tapping you are hearing could be a a lifter, valve, connecting rod...whatever it is, the tick started recently and you don't see oil on the dipstick, there is a major oil leak somewhere.
The idle issue is normal. The idle is controlled by the ECU. There are no adjustments for the idle. Regarding the knocking noise, that could be several things, and I am hesitant to comment without hearing it. Take it to a Toyota Dealer & have a tech listen to it. We are very good at identifying noises on the service drive.
It is part of the waste gate just above the gas tank. It periodically checks for leaks and pressurizes and releases. Gives a ticking noise when it does this. Not a problem and GM is aware of this and said its normal on our cars.
