    gp1200R issue

    Hi i recently purchased a 2000 gp 1200R ,99.8 hours, I took it out on the water was running full power for a bit but then all of a sudden it was lagging power only going about 40 mph. I did make the mistake of running it on old gas luckily only ran for about 3 minutes total then i shut it off. The thing is it starts first try and idles perfect. Doesnot want to die at all or have trouble keeping rpms. Should i run some nice premium gas in it and throw some lucas injector cleaner in the tank aswell. Or should i sifen the gas out before I do this. Any thoughts would be great.

    Drain the gas first. Then put premium in it with some sea foam. If it still runs crappy then the carbs probably need to be cleaned.
