Bike - WR450F '05 At a recent trip to the sand dunes, I got stuck down in a bowl, and had to really "rod" my bike to get it out... after I got out, I shut my bike down and noticed that my coolant was boiling inside my radiator. Does boiling your coolant break it down, or make it less effective? There were no apparent signs of damage to the engine, and it started and ran fine since then, but I thought I would see if anyone knows about boiling your coolant. Also, what are the most basic, (cheap) ways to get more power out of my bike? New Pipe? Jetting? better airfilter? The bike is new and I haven't modified anything yet.
