I have a stock 99 gp1200. Only thing it has done to it is preimx. Has less than 80 hours on it. It goes 67mph by the speedo some I'm sure it in the 62mph range or so. I read that j-gapping the plugs is a good trick and intake-grates, rideplates and props. Dont want to go into the engine just want to do some boltons and try to get in the 70-72 range. Whats the best combos/packages I should look into with my ski? Whats all include in Jims package? Thanks alot for any advice!
