I always use wrinkle, to help disapate the heat. The more surface area to leach heat away from the heads and cylinders, is a good thing. But nobody is making you keep it that way. But the wrinkle paint does help with cooling.
Harley never used wrinkle,just a semi-gloss black. They are silver thru '69. Wrinkle does not disipate heat,that's an old bikers tale. Any coating slows the disipation of heat, the thicker the coating the slower the heat disipation. In the old days we used to see XLR's with no paint from time to time. They just sprayed the cylinders and heads down WD-40 after the race to keep them from rusting.
And holes in the cooling fins and everything else anybody could think of to keep those things from running hot.Remember the factory iron XR-750 road racers at Daytona in 71-72? 3 oil coolers and still fried!
Thanks guys and thanks for the kind words. The wrinkle finish on the bike is starting to get crusty around the top so Im considering taking it all off and just painting it a simple silver, gray or back to a simple black like chuckspeed mentioned. Maybe a good winter project. Best way with a wheel and some sand paper?
Ive had the bike for a couple months and didnt like the yellow, so I sold all the yellow tins, found a FX tank and am now in the works to making it my own.
Here it is in the garage now. Oh and thats my sons Schwinn seat, just wanted to see what it looked like.
