I have a 06 109r. I have right at 30,000 miles on it and I pull a small trailer when I go on trips. I have pulled the trailer around 4,000 miles. My question is how many miles should I get out of factory clutch? I have a trip to California from Kentucky plained next year and I just don't want to have any trouble on the road. I have had no trouble out of the clutch so far.
