Cooler weather, I rode hundreds of miles last year in upper 30s F and slightly above. Stay warm with heated gear except annoying blast up chest to under helmet. This adds noise, too.

Currently have stock touring windscreen (too big for summer, must find solution) with laminar lip (works well, but doesn't need that up flip - will continue working with it), and large lowers to pump air behind screen (incredibly effective.

Slipstream coming up and along tank, might be pushed a little by cylinders sticking out. Already has a bit of upward flow, hits thighs, up chest and then flutters annoyingly at base of helmet. In cold, can tell is cooling my sides and chest, sometimes right chilly up against chin, have neck gaiter.

If I put hand far forward on tank, relatively little slip stream comes up. Not sure of ideal placement or size. This business of having to ride while doing stupid with hand limits experimentation.

If I put tank bag off to side, better deflection, but that's further back and I get some flutter over bag. Likely there's a sweet spot, but my bag isn't ideal for this.

I can put hand across chest and deflect air away. Get the impression this blocks a bit of the chilly against belly and chest flow.

I suspect this isn't the first time someone has tried to remedy this issue. Maybe not the first time for this bike. What might be the most efficient path?

1. Make some deflectors for forward on the tank. Kind of ugly. I have used acrylic, pieces of corner angle for drywall, and oddments of other stuff before on other bikes. Still have the size, angle, and ugly issues to work out. Just a turbulator might help, angled piece that throws off a consistent vortex and breaks the flow away from the tank, possibly leading it over my thighs instead of into them.

2. Use bag system to block. Options include a. two tank bags, one on each side, b. tank panniers, c. a home made bag (I don't have a sewing machine any more or I'd have mocked one up already). Don't know whether to just block, angle back from center line, slope leading edge forward or what. Know of any work on this?

Used to be a FAMSA system of integrated bag and panniers, but having trouble finding a range of those.

1. Ignore bike and use a wind stopper thingie on my helmet. Haven't had these last before.

Suggestions, pictures, other ideas would be super. Thanks.

I'm also considering making whatever the things that clamp to crash bars are called.
