I have 2000 miles on engine---today i took apart the gear case lots of carbon came out--greased gears with gear grease because was getting noisy--can these gears run dry for long periods and do you grease periodically??
I assume we are talking about the clutch gears side of a HT engine. Yes - they need periodic greasing. Use a sticky nasty grease like boat trailer grease. I have a home made concoction and grease mine every month or two.
I am using dry white chain lube (Teflon I believe). My logic is that something that sticks but may not be the best lube is better than one certain to get slung off. So far so good, and it seems quieter.
