hmmm let me ask some guys on highlifter...
Have you been riding in hot weather? check the gas to see if its boiling. Our's does the same thing. (vapor lock)Grizz, my grizzly just started sputtering the other week. Its never done this before but the other week it just started cutting out at about 21 mph. It sounds kind of like its backfiring and cutting out at the same time. Its rideable but it kind of sucks when you try to gas it. Anything you can contribute to help out again?
I changed the plug out today but still the same. The plug color was a whiteish color. I also dielectric greased some connections. Any advice?
By any chance do you live near Key Largo? Ever been to the "Hump" in Florida City? That is where we ride most of the time. We have a 06 Grizz and we also have problems with it over heating. Took it back to the dealer under warranty and they never did find anything wrong. As I said before, we have the problem with the gas boiling in the line. Most of the time it's in the winter when it's hot and on the dry side. Summer it is really wet at the hump and looks more like a swamp. Lots of good riding!I ride in Florida so its mostly hot but the problem occurs even when the bike is cold a week later. Tried cleaning the jets out with "sea foam" but its still the same.
