That's why I and most people hated them. Too much junk crammed into one box insted aof individual components that could be replaced. Polaris finally got smart and on later models got rid of them.Then they got rid of the Fugi engines entirtely. Big mistake imo as they were good engines,especially the 500 which had a good fan base.
