Replace a cylinder yesterday with an OEM piston and millennium recondition cylinder. I warmed it up in the garage several time to make sure coolant was circulating.
Warmed up the sled good before riding and it never cooled down longer 5-10 minutes. The sled seizes but never stopped, but as you can see, the piston came in contact with the cylinder.
Could the cylinder have been wrong diameter, it seemed to hit the cylinder below the exhaust port. The only reason I noticed the damage was I pulled the exhaust valve to look at wash. Need some opinions.
Thanks …
