I'M LOOKING FOR A CYLINDER FOR A STOCK POLARIS 600 2000 OR 2001 VES MOTOR. this cylinder had the narrow bolt paterrn for the exhaust valve about 2 5/8 inch center to center. the later 600 ves's had a wider bolt pattern for the exhuast valve. Needs to be in good condition for installation as is. I also need a piston. if you like you can call me at 763-421-1299 or email me at tom.schlichting@wolterskluwer.com
