they are designed to keep the frame cool, sounds funny but its true.I'm sure there's plenty of tape out there I could use, I'm just wondering if anyone has any experience with this or has a recommendation...
Or knows specificaly what the ports are designed for.
Hrm, interesting theory about the heat transfer to the frame. I'm not convinced the amount of heat transferred to the frame from the engine is enough to cause a significant change in chassis flex. You are correct about the ports cooling the frame, but I believe this is more for rider comfort than anything. Aluminum melts at 1200°. I doubt an increase in temperature from 100° to 150°(at most) is enough to make the metal noticeably softer. Thats just my thoughts. However, that is one of the benefits of the aluminum frame. Aluminum dissipates heat very well on it's own.they are designed to keep the frame cool, sounds funny but its true.
when it gets hot from the engine it becomes more flexable. IE I taped mine with duct tape because im only running 7 lap sprint races. not really enough time for the frame to really start flexing. now say if you were racing the AMA full 24lap races.... yeah you would want to leave them open.
also pull your water catch on your intake duct and tape it on the inside. and pull the wire screen too. : )
Nothing mentioned in this thread is going to make any real significant difference. But when you've been in racing as long as I have, you learn quickly that every little bit counts. These are just a few small things on a long list of small things. This is why MotoGP and Superbike teams strive to shave ounces. Enough ounces and you get pounds.... :facepalm:
at high speeds covering up those holes in the frame may increase your CFM by like .4
