Hello there. I'm new to the forums and I have a question concerning my new Muzzy exhaust on my new 750 Brute Force. Here's the deal. I wrapped the pipes wherever I could except for the front header pipe coming off the exhaust port because I didn't see the need. So the night I got the exhaust all bolted on, I decided to test ride it. I was cruising along at 20 mph just taking it easy. Since it was dark and out of curiosity, I took a peek at the front header pipe and it was glowing orange!! Not 2 or 3 inches but the whole thing! This really surprised me because I wasn't running it hard at all. I came to an immediate stop, got off and looked at the rear header pipe and it was glowing the same way.
This was little over 2 months ago now and I've talked to several people about it at work. Some say it could be running a bit lean and some say it could just be normal so I went with normal as I have ridden it with no problems at all. I'm still a bit concerned because I think the fuel injection would have adjusted to the difference in back pressure by now but the pipes still glow at night and I hope I haven't done any damage to say, the valves. I don't want to spend money on a programmer because the quad runs very strong. What do you guys think the problem is? Any suggestions? Thanks!
