Having issues with losing RPMs after reaching wide-open throttle. Just perform maintenance on the engine replacing all three low-pressure fuel pumps VST filter water separator filter and fuel filter on the engine. Also replaced O2 sensor. Motors a 2000 SX 225 with about 800 hours.
Just came...
My engine has started smoking at idle and excess fuel is dumping out the exhaust. I removed the spark plugs after running at idle for a few minutes and #4 spark plug is wet with fuel. Engine seems to be running smooth maybe a little rougher than normal...
Any ideas what might be causing this...
