Yeah normal. Ive read in a few places that its because in the cold weather/overnight, some of the parts shrink a little (i think its valve shims or o-rings or something) and it gets back to normal when the engine is warmed up.

I used to park my bike behind my house in the shade, i always heard a tick but now i park in front the house when its in direct sunlight for the greater part of day and it stopped happening.

sometimes higher weights mask oil leaks... even though you can use it, you should switch back every once in a while

Well this bike doesn't have any leaks. I got it in August and ran the Rotella T that the seller said was in it, until the week before last when I changed it. I put about 2500 miles on it from August until then so I would've seen any leaking when I changed the oil.

I didn't put the higher viscosity in it to mask any oil leaks. I just wanted the maximum protection. Particularly in light of how hot they run and (as steve mentions) how thin their cases are.
I rode it in to work today (30 miles) in 36 degree weather and the coolant temp still stayed right at 83 deg/C even at 85mph. That thing is still a 'heater' even in this weather.

hung/xop/mad, I really dont' think you have anything to worry about. I was just curious as to why the valvetrain clacks for that long when it only takes a few seconds for the oil to circulate. But as well, I also think it is the injectors ticking, as they are doing max duty during a cold start, as the mixture tends to be rich until it warms up.

Im not saying that you do have an oil leak but sometimes you never know, there might be hair line cracks somewhere and you wont ever know til last minute...

My sister bought a car that the guy put much higher viscosity oil in it to make the car look and seem good, no smoke no nothing. when we changed the oil though for the first time with normal oil, it was all types of trouble. its okay to do but im just saying every once in a while like 1 out of 4 oil changes, just use normal weight
