New guy here… have been reading these forus for months now and learned a great deal in the process and for that I thank you… 2 weeks ago I purchased a used 2010 850 touring eps that needed some work but overall was in very good shape… I pulled the lower right side black plastic exhaust cover cuz I could smell something getting hot and found my plastic side panel had burned through the heat shield and started to melt the plastic.. The temp here now is -3 degrees C and it took a whole 4 mins for my header to start glowing red about 3 inches back from the head. Any ideas on how to remedy this?? Pulled the two plugs and they were both a little sooty looking seeming to indicate a rich mixture. Machine is EFI. Not a plugged exhaust cuz I removed the muffler with no improvement and even tried a new air filter… please any ideas greatly appreciated! Sorry for long post..
