He explained why he bought it, twice.
Who cares ?

 I don't know why there's any personal investment in what people do with their bikes either.

 If I want to have a project bike where I do random tests on it then I guess that means some people won't sleep at night.

 On the 4runner forums I've never had anyone complain about the cost of doing tests on my 4runner that I've never asked anyone else to pay a dime on.  I had a wind tunnel built to test vibration on the antennae, it made a ton of noise in the cabin and we eventually figured out that its cross-wind from the passenger side 30 degrees from center rear (20 center front) at 14+ MPH combined with a forward speed of 60-68 MPH that causes it.  We had to build a second power/blower mechanism to simulate cross-wind just to figure that out.

 The solution was an angled antennae for maybe $15 but sometimes a project is just fun to do.

 Not one person felt the need to complain about it or try to convince me how much not to spend.  No idea why its an issue here.

 So this bike has gone 3000 miles with the 150/90 tire and we still aren't getting any noticeable wear on the belt or bearings.  The tire is showing wear which is expected of course.  

 Its on the same route every day, mostly straight roads at consistent speed.  Would changing the route to have more stop/start change anything regarding wear to the belt/bearings?

 Well with the weather being how it is I am pulling all the bikes Nov 1 and getting them in the shops.

 This bike never started to squeal again even with just over 6000 additional miles run on the 150/90 tire.  I will try to find a shop that knows about this particular bike enough to look over the drive system and see what, if any damage was done.

 I was hoping to replicate the original issue as I was repeatedly assured it was from the tire but it didn't work out this time.  We will see what happens next spring.
