Can anyone tell me anything about the power valve system on this sled . one of the cables broke and siezed up the cylinder not bad ,but enough to have to send it to us chrome or get a new one. other cylinder also has a slight scare top to bottom on now i it will need two cylinders now. the sled has 3400 miles on it. Is this sled a problem sled or what any info would help can anyone tell me where to get the cylinders fixed cheap or where i can get used ones. This sled is in great visual shape ,otherwise looks like new . Thanks for any help.
