Yesterday I picked up a 2004 ktm 625 smc for a great price, bike runs beautifully, but not too sure about keeping it running like a top. I've never had a liquid cooled bike, is there any major things that I need to pay more attention to? What oil would be best in the desert as I live in Tucson, AZ. I run 20/50 in my aircooled yamaha, is that too thick for the lc4? Any help is much appreciated, and I'm excited to start cruising around on this bike!
