i have not had any of the conditions that you describe.i have approx. 700 miles on my z1.with what you describe you should have had a temp. lite come on, or the sled will shut down automaticly.hopefully the dealer can sort it out bang your head keep us posted!!!
I had a set of plugs go before I made my first trip. According to Cat you can not idle these engines for short periods of time or it will foul plugs, and believe me, you don't want to have to change plugs on the trail. You have to take the hole top end of your sled apart, not a fun job. :bang your head: As far as the pipe goes, I've never noticed. I'll have to take a look the next time I'me out. :super_happy:
