I just bought an 03 700 rmk with 3000 miles on it everything seems to be in good shape so far, i was just wondering what maintence i should do to it? it seems to have some oil dripping out of the exhaust manifold, right around the gasket, i was wondering if this is a thing to worry about or not? and i need to change the jets and weights in it because its set up for the mountains so any help would be appreciated.
