SLX1050 boggs at part throttle... - PWC Forum: The best hang-out for Personal WaterCraft enthusiasts

I've got a 99 slx1050 thats been having a progressivly worst problem. It starts and idles fine, and if you slowly bring it up through the throttle to WOT it runs fine, but if you go from idle to WOT it stalls/boggs down. I've been riding it quite a bit so I know its not old fuel, and i put some new plugs in it and that didn't help...Any input appriciated...

Rebuild the carbs for sure and I would change the old fuel pump to a pump with three outputs......the single output of the fuel pump is not supplying enough fuel to the Mag carb. (Carb on the front cylinder)
