	Took my head off my indy 500. And i can take my finger and move the pistons from side to side about a 32 to 1/6 inch. Is that ok or should i rebuild? Rating: 0 Quick Edit Edit Topic

	You should have .004 thou of an inch clearance between the cylinder and piston walls when the motor is new. As the motor wears this will increase somewhat. You can check the wear status of your motor by measuring the piston to wall clearance spec and the piston ring end gap specs. This can be accomplished with a good set of feeler gauges. This would also be a good time to measure the cylinder bore and check for cylinder out of round issues, if they exist. 2006 Skidoo GTX 500ss 1983 Skidoo Blizzard 9700 1982 Skidoo Blizzard 9500 1981 Skidoo Blizzard 9500 1980 Motoski Supersonic 1978 Polaris TXL 340 (2) (2) 1977 Yamaha SRX 440's 1977 Arctic Kitty Cat 1975 Yamaha GPX 433 1971 Arctic Panther 399 1969 Skidoo Alpine Rating: 0 Quick Edit Full Edit
