I just watched the 2nd 125 moto @ Washougal. When Brown's bike walked past Ward's 250F uphill , I thought it was odd. On the straightaway, shortly thereafter, Ward's bike was billowing out blue smoke. Bailey said, "I guess it's a little overflow, or something."
Gee, out of all the motors I've overhauled, with my first smallblock Chevy in 7th grade, I can't recall the term "overflow", and have never seen a 4 stroke billow blue smoke without there being something seriously wrong. Recalling that his mechanic said his first moto results were terrible (bike was underpowered) because his airbox had a hole in it....???, something's fishy here.
He had to have smoked some valves, seized a valve in a guide, or...Something serious happened.
What was the fallout here? Anybody hear anything about this? I'll bet Yamaha's keeping it quiet, for good reasons. :think
