Greg_650, first i should say thank you for continuing to humor yourself with me and my challenge! Same style jeans, areas were just approx. 1/2inch apart. I do not think I want my jeans to touch it at 400 degrees! It has been 85-90 degrees and so humid you can barely breathe around here lately. Bike seems to run right, except occassionally gears not engaging on first attempt during downshifting.
Ah, Humor, a wonderful thing....but I'm not doing this at your expense. Really. And trust me, this isn't just a challenge for you...we're all in this one
Don't get me wrong, but if I don't ask what seems to be the silliest, strangest or the most redundant of questions for things that are rather inconceiveable and outrageous anyway, we'll never figure it out. After all, I'm pretty sure that "Jeans on Fire" is not listed in the troubleshooting section of the manual. Okay?
Never realized the actual temperature of the engine parts, did you? Most people don't either. We're all too used to watching a water temp gage in a car and worrying if it gets up to boiling. So the idea of temps like that can be surprising. Just remember this is an air cooled engine just like your lawnmower....
The head/cylinder metal can easily reach those temps; especially near the exhaust port. The temps inside your exhaust header pipe are even higher than that, as there is pretty close to an open flame going on there.
Oh, did I mention that the cooling fins on the engine do work? Way out on the edges, it isn't nearly as hot as it is at the bottom of those fins....heat is dissipated into the air and water (and clothing) that comes in contact with them....so they are most likely not actually 400.
You aren't mad at me, are you? I am trying to help.
So, let me ask, do you iron your jeans?
