Hi Blue Grizzly_04,
I have only taken it out on a short ride (+/- 45 minutes in light rain) so I really do not know if it will burn the plastic yet. My initial concern was after I read on ebay (Power Tip for Yamaha Grizzly 660 and Rhino 660 Exhaust) the seller says...Our tip directs the exhaust flow down and away from the rear fender. Beware of other tips out there on the market that come straight out. They will melt your fender!
So I went to look at the back of my Grizzly again, and I noticed that the edge of the fender, and a whole chunk of the overfender, seems to be in the LINE OF FIRE of the exhaust.
I dont think the exhaust is running hotter (as Marine agrees) but the original tip points downward and the 2" billet tip points straight back! Therefore it may melt the fender and overfender!
Anyway last night I took Alunimun Foil (Ovenliner) and Electricians Glass Tape, and i made a sheet with 2 layers of each, I then used contact adhesive and lined the inside of the fender and about 2cm of the lip. I hope this will prevent any damage. I will test it out this weekend!
Hey Marine, thanks for the advice again! it is always "spot on" and appreciated. I will check my plug after a day or two of riding to see if I am running lean.
Thanks!
