I used to foul plugs on the ol zrt about every 200 mile. Now with the firecat, I run an entire season without fouling. I change them after the first ride of the new season since I fog my motors, and then dont worry about changing them until next year. ITS GREAT!!!
Likewise, after the first run of a season I put in a fresh set and am good for the season.
Two reasons, the fall fogging and the first run of a season I also run a fuel/oil mix just to verify the oil pump is still functioning.
Never fouled with the SkiDoo, we'll see how the Yammi does this year. Had her out last weekend for a little romp, and will put the new plugs in tonight. (the old ones looked fine after riding last weekend, but are last years - and we don't want last years model in there with the way the "new plugs" look, gotta be fashionable you know :lmao: :lmao: :lmao: )
