depends on how serious of a rider you are .. are you rocking the throttle pretty hard alot of the time.. it's right up there with suspension and power commander.. i think it's a necessaty on the 929/954.. on the 1000rr's they all came with one from the factory.. some people still replace those for an aftermarket one. so yes it's worth it.. if you ever get a tank slapper you'll find out why..what is its the function? Im a pretty simple person so you have to spell it out for me sorry. lol I was wondering if its good enough to put on the bike for a performance upgrade.
Between all my cars and bikes I do about a dozen oil changes a year and probably half a dozen coolant changes.going to change the oil might even the cooling fluid. have you ever done that before?
