Sled starts and runs fine, but when going full throttle, it seems to "bog down". I let off and slowly roll back into, but once past about 60-65 mph it starts to bog down again. HELP!!!!!
When is the last time you changed the fuel filter? It's pretty critical in the EFI engine. I would also take a look at the VES valves. While you're in there, take a look at the mag side VES spring, I'm betting it's rusted.
Not sure if this is a clutch issue, belt, or even the dreaded engine issue. Any advice is welcome. Newer plugs, (less than 50 miles) and also newer belt. maybe 200 miles on it.
