    gs550es jetting question

    Well my 4-1 yosh came in the mail today for my 550es. I am not looking to purchase a jet kit unless it is absolutely necessary. I figure raise the needles and go up one or two on the mains and adjust the air screw. Any one have any suggestions. Gonna keep the airbox and use a uni foam filter.

    Hi,

    I like your plan. It shouldn't take too much to dial it in since you are keeping the airbox. Plug chops would tell you for sure. A couple of links from some guys' website...

    For CV Carb jetting, see the very informative article at Factory Pro. Also see the carb jetting tips at Motorcyclecarbs.com, Inc.

    Thank you for your indulgence,
