Is the 400 a wet or dry clutch. How do i clean it up?Is it better to overhaul or replace front brake master cylinder? The bike has been stored for about 16 years. Should i flush the engine or just drain and refill. Does the motor oil take care of the clutch and transmission or do I need separate lubricants? Where are the best source of parts? This bike only has 2830 miles on the clock no scratches. seat leather perfect tires are good.Just needs cleaned up.
