The rules are at best flawed and anyone could find something to pick on virtually any bike and have it upheld if they wanted to, which leaves the whole situation open more to an individuals personality. Forget the '78 bikes masquerading as '77, no qualms there, but rubber mounted bar clamps is total BS. I find it hard to believe that you can have modern shocks, tapered bars, modern style expansion chambers etc, but yet to race a bog stock off the showroom floor, '77 Husqvarna or Montesa, you have to REDUCE the suspension travel. Huh? As for Belly's brakes, IMO they are not legal as they are clearly a performance advantage. That .2 of a second he gained every corner of every lap certainly helped his lap times, even though he still could have won by a country mile on the standard items. Maybe this is why his bike didn't get a protest, but it seems he was cut some "slack" or maybe his status was intimidating to the other riders. Going on the pre '78 125 solo protest, any rider in Belly's class could have protested and have had it upheld. Wouldn't that have put the cat amongst the pidgeons? The guy who made the protest in pre '78 125's was beaten by better riders, pure & simple. He knows it too.
