Header wrap is not good for titanium headers. Plain steel wrapped headers need to be stored dry, so run it after you wash it.
My XR400 has stainless headers. I have been running wrap for over 7 years now. My XR100, 4 years. My TRX250, 6 years. The XR200/Lifan, a few months. No failures...
Ever notice how a motor is really snappy when it is warming up, only to drop off some after it's hot? Mine runs snappy regardless of engine temps, because they are lower. My engine temps are lower, my oil temps are lower. I have no idea about any added performance, other than the bike runs snappy like it does at the beginning of a ride, all day.
I have a quad that I use for trail maintenance. Miles and miles, under 5 mph, pulling a 100lb grading sled through sand. Before wrapping the header, I would have to put my foot on the fender, the heat radiating from the header would burn my leg, even through long pants. after wrapping, feet on the pegs and no burns, even when wearing shorts. There is no way that kind of heat can be good for a motor or it's lubrication. The same heat that burned my leg 8 inches away was only 1 inch away from the cylinder cooling fins and oil transfer lines and passages...
That website want to sell you a coating, and tries to give reasons not to buy something else. The coating is good stuff, no doubt. But the reasons they give for wrap being bad simply dont apply. Small bore motorcycles are not NASCAR machines, and dont subject their parts to the same conditions.
