Haven't used it.  However, with the triple digit temps they've been seeing in that part of the country, the higher viscosity may be a good thing.

I use 15-50 semi-synthetic. My mechanic highly recommended it.

Only complaint I can say is, first thing in the morning, its cool
get on it hard, the clutch slips, but just 5 min. later, bike is warm
enough that clutch stops slipping. Just my experience with semi-syn.

Full syn could work better.

If you have been using Dino up until now, I would suggest not changing to a different oil like you suggest.

It would be better to wait until you get home to experiment with the oil.

I think the clutch slippage problem is caused by friction modifiers in the oil not whether it's synthetic or a blend of synthetic and dino oil. Most car oil has friction modifiers to some degree.
Many of us have used Mobil One synthetic 15w50 and some have had clutch slipping problems. I make my own blend by adding diesel oil (which has no friction modifiers) 1 to 1 with Mobil 15w50. I haven't had slipping since I started using my version of semi-synthetic oil. You can't go wrong with a diesel oil, pretty cheap too.

I use Mobil Delvac 15w40. Chevron Delo or Shell Rotella would work as well.

I have been using Mobil 1 10W40 High Mileage.  The Mobil 1 High Mileage oils have no friction modifiers.

Bobby, he probably doesn't know you are a diesel oil expert.
