pistons

#1 PostAuthor: Simon Jones » Thu Dec 31, 2020 4:25 pm

I have a 1170 wisco kit and and oil ring has picket up
Does any one know if i can get a .25 mm oversize piston kit instead of going out to 1260 cc which i believe is the next piston size wisco do
Thanks in advance
Simon

There is no oversize for the 1170 kit, it bores std liners 'till nearly transparent. Next one up requires oversize liners. Cheapest way out is another 1100 liner and have that bored to the piston size you have.
What has been damaged? Liner or piston also?
