When riding our vmax this weekend I noticed it started to smell hot. The rpm's wouldn't drop until I blurped the throttle. I replaced the plugs and now when she starts up when she is cold all of a sudden the rmps will kick up to about 3 thousand and then they drop back done again, it will do it several times. Also the sled now has a deep growl to it that it has not had before. The sled as almost 8000 miles on it. Could the pipe or can have rusted somewhere and have caused this??? Any ideas?
