Defo need to do something about the screen, the air seems to be hitting me in the neck more than anything. Did about 50 miles, local roads were quite greasy so wasn't too exciting, just an excuse to fully charge the battery I suppose. Currently got the long baffles in the Wings exhaust and is far too quiet I reckon so they need to come out.
What is it with these touring screens now. They expect riders to be the stature of jockeys. I think having it hit in the chest can be better than it hitting in the head. Never had an issue on sports bikes and also never had an issue on the SMR with zero screen.

From what I read of the blurb I think the problem is these screens create and area of low pressure between the rider and the screen so that fast moving air pushed over the top of the screen is sucked downwards into this low pressure zone rather than being deflected over the riders head, creating a vortex of "dirty" air which is turbulent and noisy and constantly batters the rider's head or chest. The screen would have to be enormously tall to keep this vortex above your head.

The Palmer screen works by allowing sufficient airflow under the screen so that this low pressure area is neutralised, a vortex is avoided and proper deflection takes place and the wind blast flows more smoothly over the rider's head.
This theory seems to be born out by the fact that drilling holes along the base of the close-fitting KTM screens does improve things but they're still not on par with the Palmer.

Hi,

I like the bike in white. I noticed that you have removed the stock heat shields. I was wondering if you have run the bike with the factory bags on and the aftermarket exhaust. Any problem with heat and the bags?

Thanks

I didn't remove them, the previous owner did, probably because he never used any luggage, so can't help there sorry.

Its the cats that generate the heat. Straight-through after market cans don't get anything like as hot as the OE catted cans. I've used hard and soft luggage with my Leo Vinces without heat shields with no problems at all.

In fact, when I bought a Kriega tailpack and some soft panniers, I rode the bike to Zen Overland where I was buying them to make sure I was buying something that I could make fit. It was an hour's ride, some of it stuck in slow traffic, and when i got there I could bear my hand on the cans. If the luggage had come into contact with the sleeves of the cans I doubt it would have come to any harm. Avoid contact and keep luggage out of the direct exhaust stream and I can't see you'll have any problems. I've never fitted the stick-on heat shields to my Trax hard panniers either and they're fine as well.

Awesome! Thanks for that. I have a similar setup with my SMR but haven't actually tried it with luggage attached.

My bike is fitted with (de-catted) Akras and no heat shields with the standard KTM semi hard panniers with no problems at all. Interesting theory that the cats could make a difference - makes sense.

When I had the stock exhaust on my 690 SMC it got so hot it melted through my bike cover :oops: Never any noticeable heat with the akra it's got now. Catalytic converters need to be roasting hot to do their job properly.
