I have a 2008 WR450F that was bought new in 2014. The engine oil and filter is changed every other ride (trail rides) or every 200-300 miles at times because the bike is tagged and used for some dual sport riding. Of course during oil changes as expected I would noticed the normal wear and tear/clutch residue that discolors the oil but also leaves a film inside the engine and can be noticed at the oil filter pocket area. The oil is changed while hot but also some cold oil changes have been made.
Has anyone every tried using an internal engine cleaner like Seafoam through their engine before oil change?
I was thinking of adding a few oz's of Seafoam start the engine and let it idle until hot and then drain the oil change filter etc. Thoughts?
