im looking to buy at a 2004 wolverine,the machine looks overall good,with on exception,the exhaust is orange,from the head to the muffler,any ideas what this might be caused from?motor to hot,valves need to be adjusted etc..........thanks for the help

 

If its a factory exhaust they all do that. My wife rides a 07 Grizzly and her muffler is orange after a year!

 

Prolly the effect of muddy water hitting hot exhaust pipe
