Just for interest sake to everyone that think I am crazy, just received the specs on engine modification for the 1000km inflatable race in December, devided into 3 classes, 1. standard specs, 2. blueprint modified, 3. fully modified motors .... see the information to follow .....
1. STANDARD SPECIFICATIONS?Spark plugs and spark plug caps may be replaced by others of other characteristics.?Revolution counters may be installed.?All auto lubes may be removed, together with parts related thereto.?The rubber engine mounting may be replaced with solid or mounts with similar characteristics.?Springs may be added to the throttle lever of the carburettors?No skimming, grinding or machining of any part is allowed.?Electric starts are not permitted.
2. BLUEPRINTS SPECIFICATIONS?PISTONS - Where a dimension is quoted on a piston, metal may be removed to reach a specific weight, provided the dimensions are maintained. Should there still be an excess of weight, this may be removed from the inside of the piston. Example.. the inside of the skirt or the area where the gudgeoned pin goes through
FLYWHEEL - Holes may be drilled in the flywheel to reduce weight. It is not allowed to reduce the outside diameter or to reduce the thickness at any point.?CRANKSHAFTS - Holes may be drilled in the crankshaft to reduce weight. It is not allowed to reduce the diameter of the crank.
CONNECTING RODS - It is allowed to reduce the overall weight of the conrods by removing the flashing on the shank of all three connecting rods to attain the weight spec, provided for in the homologation specs.?ELECTRICAL COMPONENTS - It is allowed to remove any excess wiring, heat sensors, rev limiters, low oil sensors etc. It is forbidden to modify coils, to rewire coils or other components, to tamper with CDI units or to add any electrical component (starter) or any other part that is not a standard original part.
3. MODIFIED SPECIFICATIONS?Propellers/Jets are free.?Re-boring is allowed up to a maximum of 849cc (1mm oversize maximum on pistons)?Bullet or racing gearboxes are allowed.?No restrictions on welding of the crank.?No restrictions on dimensions quoted.?No restrictions on weights quoted.?Measurements not quoted in the homologation sheets may be altered.?Parts may be changed with another manufacturer.?Holes may be drilled or cut into the exhaust trunk, but no external appendages may be added.?No protrusions other than standard are allowed.?No protruding expansion exhaust box.?Motor cowlings may be altered to increase air flow.?External water pick-ups are allowed.
...... cool hey ....
