Our racing season is coming to a close, and I'll have plenty of time this winter to rebuild my ride. I've never owned a bike this long prior to this one, so rebuilding it has never been an issue before.
I have a bone stock 2013 KX450 with nearly 140 hours on it. I race MX in the +40 class. The bike only gets used on motocross race weekends. I have changed the oil every 10 hours. The valves have been inspected and adjusted as necessary. I replaced the piston at 80 hours, but that was just a precautionary measure. The bike runs perfectly, but I don't want to push my luck. What should I replace over the winter, and what company/services should I utilize to do the work?
OR...
Am I better off just selling it and forking out 9 grand for a new one? Problem is, as a 6'4" motocross rider, I really like the layout of the chassis on this bike. Plus, believe it or not, Factory Connection has my air forks working great for me.
