I purchased a 03 dirt cheap and I assumed it only needed a new battery and fresh fluids after sitting for nearly 2 years. After purchasing a new battery the bike still would not start so I pulled the plugs and ran a compression test. The numbers from the compression test were very close to 120 for 3 plugs and the last plug on the clutch side was 89. Here is a picture of the spark plugs I removed. They appear to have oil on them. What could be the problem and will it be difficult to fix?
