About rules:....I was thinking something along the lines of this:
- Must have been available prior to year 1990
>> Drive
- Must retain OEM clutches. Springs, weights, ramps, helix may be changed.
- Gear ratios and chain may be changed.
- No machining of clutch surfaces.
>> Track and Suspension
- Speed tracks are NOT allowed in stock classes. Minimum 0.725" lug height.
- OEM suspension must be used, addition or removal of wheels permitted.
- OEM ski's or aftermarket ski's must be a minimum of 40 inches.
- Suspension must retain 2" of front and rear travel. - The only way of lowering a sled is by using the provided factory adjustments. No additional straps, chains or wires permitted.
- Carbide tipped trail studs only - no ice picks or chisels
>> Frame and Body
- All factory installed componants must be present and un modified. Hood, Frame, Gas tank, Carbs, Air box, Suspension, Seat. No drilling or lightening of sled permitted.
>> Engine
- No component of the engine may altered, changed, reduced or enlarged from the engine manufacter original stock specifications. - Nor may any additional componants be added to the engine.
- Blue printing of engines is not allowed. No removal of material whatsoever will be allowed. This is to include polishing, port matching, deburring, glass or sand blasting surfaces or materinal removal for the purpose of engine balancing or other reasons.
- No more than one cylinder base gasket to a cylinder.
- No aftermarket reeds, reed spacers, pipes,cans, air boxes, carbs.
- No turbo, super charging or Nitrous allowed.
- Pump fuel only - no race fuel allowed
We still have to figure out displacement, but Claude will probably not want to create a pile of classes. I would bet there will be only 1 class for vintage.
