The starter doesn't disengage as soon as I let off the button and whines along for a couple seconds with the engine.

Combining this post with your other one about the bike not wanting to get to neutral, I would advise you to take it for a short ride, just long enough to heat the oil to normal riding temperature, and then change the oil, and the oil filter.

You might be surprised by the result.

I will be changing Tuesday with Honda 20/50 when the shop is open but the oil in the crankcase looks new. I suspect something else is causing it.

Most likely a real "Bike work out", and, as I stated before, an oil change, will get it out of her system.
These bikes were built to ride, not to be an expensive asset in an air conditioned living room.

20-50 is too heavy. Honda calls for 10-40 or 10-30. Lighter weight oil has less drag on parts and cools the engine better.

My owners manual has 20/50 as the optional weight for my riding conditions and there are a lot of other Xers using it. I run it in all my bikes.

Riders with oil temperature gauges find that their engines run cooler with light oil. Heavy oil creates it own heat and friction.

IMHO

I have an oil temp gauge and it runs between 180 - 230. When I got my first X it was behaving like the pistons were about to seize so I came on this forum and was advised to use Honda 20/50 dino or synth. I stuck oil pressure and temp gauges on and replaced the 10/40 crap oil and have been ok ever since. I wish I had installed the gauges with the old 10/40 oil so I could see the difference but I am sure it was nearing 280 or 290 before. I am still holding my breath one year later hoping I didn't set something bad in motion but so far so good.

I am sure each bike is a little different as well as riding preferences and conditions so there is no right or wrong as long as good quality oil is used. I drive my bikes easy and rarely go on the highway very far and prefer quiet rural farm roads.

Thanks for the input as always.

Not really an opinion. Most all tests show that a thicker oil is especially harmful upon startup and has no benefits over a lighter weight oil even in hot weather riding.

I am sure we beat this issue to death in years past. It come down to "choice". Some will not use anything but synthetic. Some will only use heavy oil. Others will use light oil.

Honda says that they have never had an engine failure attributed to motor oil.

In the final analysis, you put down your money and make your choice. Some people ride Yamaha's, some ride Kawasaki's, some ever ride Suzuki's, Harley's, or Ducati's.

It's just a matter of personal choice.

After 2000 miles the starter is now failing to engage the engine every time. I have gone from a whining starter sound when I brought the bike home to not engaging. Any ideas? On my 69 to 82 CB750's it usually means one or more of the starter clutch rollers has dropped out of place.

My starter clutch on my 82 with 96,000 miles has been 'failing' on occasion too, cold mornings or if I haven't started it in weeks, but its been doing it for over 30-40,000 miles so when the cases have to come apart for something else, I'll get that fixed. My starter never whined but before the cause was determined to be the clutch, I went thru two starters.
