Mine's shot. Wondering if anyone has replaced it with aftermarket or oem. I can't seem to find a dealer that knows where to get one.
I think I'll take the bottom section to the tractor store for comparison and see what they have.
YLEE has it right.
Take the bottom section only to an upholstery shop that does MC seats. I have 1-2 ATV seats done per year by a guy in San Jose. There should be at least one shop in Oxnard. I pay about $75 for labor and materials (vinyl).
My CK30 seat bottom has some cracks after 15 years, but not all the way into the foam. You can choose foam density if you go to a shop.
