Hey guys I just picked up an 08 KX450F in pretty good shape. The guy I bought it from just used it around his place and did one hare scramble with it. The valves were checked and are in spec, it runs great, and the suspension is supposedly fresh (I could debate that one). Anyways, it is totally stock, is there any immediate small touches I should do? I was thinking about draining the coolant and running Engine Ice, good idea or no? Also, whats the common oil everyone runs? The guy who I bought it from ran Spectro 10-40 semi-syn. And whats the best foam-filter oil to use? I have some UNI stuff left over from my quads, but I have been told to use some other brands that of course I can't remember the name of. Any tips and tricks would be appreciated!
