Hi guys, considering making the plunge into the orange kool-aid from my '03 Honda XR400R. Found a 2014 500EXC for sale with ~600 miles, 23 hours. What should I look for when I go to see the bike and make the deal??? He has already de-smogged it, turned up the TPS, bypassed the thermostat (don't know much about that), and replaced the muffler end cap (Power Quiet End Cap). I know the basics like oil, sprocket wear, bearings, and cold start-up smoke... what else? It's a lot of money (for me at least) to spend on a (mostly dirt)-bike, so I don't want to be careless here.
