if so, would you do me a favor see if exhaust pipe is still cherry red after dark about 7 inches out of the head thanks fellas
yes i have heat shield installed as well and its a fire hazard with out wrap on i think. just wanting to see if aftermarket exhaust was any better for the glowing pipe
my concern is debre getting on my installed aluminium plate and fire starting .My Yamaha mechanic said it was normal and perfectly fine. He strongly discouraged the heat wrap because he felt it did not allow the pipe to dissipate heat properly and could transfer excess heat into the cylinder head.
seen this first hand not good ! was a new Polaris 110 miles on it.I can see where fire would be of concern, but I would think that whatever gets on there will be small and the fire would be minimal and short lived? To me, getting that head hotter than it needs to be is more of an issue. I plan on installing a fire extinguisher anyways, actually I already have it, just waiting on the mount to come in. Last thing anyone wants to do is to stand there and watch their machine burn to the ground!!!
Somewhere on here is a thread where someone above and beyond and measured temps on the differential pre and post heat shield install. It was to say the least, a significant reduction, somewhere in the neighborhood of almost 300 degrees down to 70'ish if I recall. As soon as I get better and learning the ins and outs of these threads, I'll be able to find it again easily. Until then, my apologies for the teaser.so why the heat shield? Is the rear diff getting that hot?
