My sled has ran perfect for the last three seasons. The last ride last year it started fowling plugs on the can side. changed out the plugs ran sea foam through it. But it still does it. If I keep the RPM over 7000 it runs great pulls strong. but within a minute go dropping down below 6500 it starts bogging again. today I pulled the injectors out cleaned them and fired it up again but it still seems to be over fuelling on the one side. Thinking about buying new injectors. Just wondering if anyone else has had this problem or can suggest something else I can try to fix it..

Thank to anyone that can help.

I’d put money on the reeds. Cat ones chip and crack easy

Thanks guys. I'll be home Wednesday and the wife's working so I'll clean the power valves and check the reeds. I falls good I'll be headed to valemount Thursday. Thanks again.

Mayswell order reed pedals now, 99% chance it's reeds and if not you'll need them sooner or later

Agree with that, if you are digging in to check them it is the time to change them.

Thanks guys. I stopped in to Travis's auto on Friday. He let me use his shop ( had my own tools). And yup huge hole in the reeds. Travis gave me a head and within an hour and a half the sled was running great. He suggested I put the reeds from a 1000 in. He says they last longer. So that's what I did. It pulls like a beast again. Now I need more track. Lol but that's a summer project. Thanks again guys for the suggestion.
