I for one can't get over the fact that so many of these 4 strokes have been grenading on a regular basis. Color and team doesn't seem to matter. I read where many last week again blamed KTM's 350 for being overly built, nonsence.........They are 2-2.5 hour run time engines and for all practical purposes, and then scrapped. I remember the days when Red Bud meant the sweet smell of leaded high test premix in the air. Now when i go for the July nats, all you smell is burning oil from the engines on the edge of exploding! The best hand built parts in the world, where money is no issue still seems to have little effect on failure rate. Just imagine if the pros truly did ride production engines...With only exhaust and tune up. It's my belief that less than half would consistently finish at that level. If you have never been to a outdoor national, ya better go and see for yourself. At the end of each moto, nearly all bikes with top 10 fastest riders have obvious signs of engines on the edge of failure. Outdoor is without question the real deal for both man and machine. SX is entertaining when it's snowing outside, but otherwise turning into a sideshow where overall focus has less to do with racing each year.
