It's fuel injected - just plug it into the computer and see what's doing
To the best of my knowledge there is no 'matting' around the head pipe, but my CRF runs red hot for about 10 inches from the head and once I tried running 100 octane (calls for min 93) and the exhaust ran exceedingly hot - melted the side cover over the muffler on the rear of the bike (about 4 feet from the head) - a red head pipe is mostly normal - the exhaust temp is about 1200 degrees - it didn't do it at idle and it didn't do it with the cast iron exhaust manifolds, but my 65 Mustang with steel tube headers glowed a dull red when running 70 MPH down the interstate. First time I noticed it I had just pulled into a rest stop on I-65 in Indiana and parked under a tree, got out of the car and saw a glow from under the car - thought it was a fire under the hood - grabbed a fire extinguisher, opened the hood and saw the headers glowing - ran the car over 100,000 miles and never hurt a thing. I noticed the head pipes glowing on my 72 Triumph 650 Bonneville glowing the first time I was running it in the garage - wasn't sure what I was seeing, so I turned the light off and that confirmed what I was seeing. I don't worry about it unless I can see the glow in sunlight. My CRF will make the pipe glow in sunlight after about 20 minutes of hard high speed riding and it's been that way since 2004.
