hi guys i have two questions, first I just bought a honda 420, Ive heard guys say you should adjust the clutch every oil change? Is this true and how hard is it. The second question is that I do a lot of water, is there any vent lines that I should look out for on the 420. Its EFI do they have a vent line off that and if so does anyone know where it is. Thanks, you guys are always a big help
