I finally updated my old carb gti's for a pair of efi Yamaha's. If any are thinking about updating dont make the mistake I did, not bashing yamaha but after riding a seadoo there really isnt another ski. So my wife wont share the GTX So im stuck with the fx140.... the yamaha's seem to be heavy in a turn with slower responce.. but the good news is I saved money on my car insurance! lol
