Fellow TTer's need some input as to what is the hottest temp you can take the WR series bike to. I recently put a trail tech Vapor (has a temp gauge) on mine ('03) and going into the Sierra mountains here in Calif. recently got the temp up to 230 degrees. I've had no problems with the bike since. I know in automobiles when you get it to this temp (230 or better) your usually going to blow a head gasket. I did a brief search in the manual with no indication of max. Any ideas?
