Hello, I have an 89 fxlr with an evo 1340, 40K miles. I recently went on a long trip and noticed I was getting some smoke from the exhaust and the guys behind me said I was putting off some bad fumes. I am not sure if it relates but before the trip I replaced the two oil filter lines. I used some bulk line from the auto store. The line from the front was a little crimped. Iam sure I should replace that but not sure if it would have anything to do with the fumes? Suggestions?
