The issue is that everyone complains about these "problems" with the current race series, but does NOTHING to help solve their problems.
Do you guys forget that guys used to race multiple series, of multiple disciplines of racing all in one weekend? (The guys that are more hardcore and more faster than anyone these days on their new fangled high strung expensive 4-stroke machines that the privateer can't afford.)
Get over it. Go start your own series. Get your own sponsors. And heck, make it so a 250cc 2-stroke can race against a 250cc 4-stroke, and allow 700cc 2-stroke fire breathing monsters if you want. Make your own rules & enjoy your spectacle.
Let's enjoy more of the great racing we've already gotten to see this year.
