So would there be a benifit of shirlding the engine from so much cooling? As the have an fan with the cowling as cooling. I ride mine about 20 minutes at a time more at 3/4 appx 23mph. I would have thought she'd be warm, Hotwater bottle?
I never tried this, and don't recommend it, but if you want to experiment-
You might stick a few small pieces of duct tape on the cylinder fins to cut some air flow. Go easy here, you don't want to block it all. It's been 25 years, but in the old days flying r/c planes we put a little tape over the cylinder on glow engines to fly in winter. They won't run for crap when they're too cold.
You can always reach down and feel the cylinder, if it gets too hot peel some off.
