Please help my buddy. He has a 1996 KX250 that he recently purchased used a few months back. I know the original owner and complete bike history. Anyone else out their with frequent spark plug filings? I run fresh gas with quality oil at 40:1. The bike runs strong, the only problem is after it sits for a couple days it always fouls the plug when starting. Change the plug and no problem.
