Does anyone know where I could get a tope end rebuild kit for my ski? It appears I hung the exhaust port with the ring and it chiped part of the top of the piston.

I called PPG and they said they dont have one and would haev to sell me OEM parts to the tune of about 650$ I have seen the kit for sale with WSM pistons on the STB site and a few others. I would rather spend it with the site sponsors here.

any info would br great!
