I don't like setting out on something I've never done without an experienced person to help. It would be nice if I lived a few hours from someone who knew their shid. I change the oil and filter everytime and save $110.00 minimum every change. And if I go to the purolator, you can make that $120.00. When GPW gets finished I'll be on syn and I guess that might double the miles between changes. I've downloaded the manual and the drawing shows the plugs way down in the head so I don't know about that one. That wold be as easy as changing oil if special tools weren't needed. Don't know a thing about syncing the TBs and don't have a manometer. Need to figure out tire changes for sure. I have found someone to do it for $25 a tire, dealer got me for $100 on the first one.
