700 FI fouling plugs

[grizztracks]

Anyone having problems with their 700 grizz fouling plugs? I've got one that runs fine but after it sits for a few days I have problems starting it. It fires but won't start and when I pull the plug its fuel soaked. I've cleaned the plug but normally it takes a new spark plug to get it running again. The machine has 250 miles on it and has gone trough 5 plugs. I'm not sure if it's over fueling during cold starts or if the plugs are just failing.

Fuel injection is great when working properly but a carb engine is much easier to diagnose.

You may have a fuel injection problem. I would take it to a dealer for diagnosis. I have 3500 miles on the same plug and a friend has over 6000 miles on his original plug.

sounds like the injector is leaking down when shut off.

i have a 07 and recently started skipping and running terrible at low to midrange but almost ok at top end, The shop said the throttle position sensor is way out of spec, had to replace it.
