Just had to put a piston & cyl. in my son's 99 ZL 600 with only 3,000 miles on it .This sled has not been beaten on (it was mine till i got my F7) is this common? Iknow in 1998 they had a problem with the 600 blowing pistons& cyl's .My dealer said it looked like (coldseize?) to him we hadrun about 35 miles then stopped on the lake to watch dragraces for about 3hrs .My son started sled and let it run for 3or4 mins. and didn't horse it when he took off. Went about 1/2 mile then died . Is this common (coldseize) ?It's costing about $600. or $700 to fix it with my luck my f7 will be next .Could this be related to the 98 600 motors? and what is coldseize?
