Race Modifications

On top of fixing the engine, this is the list of the modifications I'll need to make to ensure it meets the race regulations:

(I've referenced Chapter 15 of the GCR's (Manual of Motorcycle Sport) and Preston Race Clubs F1 Pre-Modern Rules) Hopefully I haven't missed anything!


  • The following must be removed
          a) Headlamp;
          b) Tail lamp;
          c) Reflectors;
          d) Horns;
          e) Traffic indicators;
          f) Rear vision mirrors;
          g) Centre and side stands;
          h) Registration plate / bracket and label holder;
          Any sharp edges left by the removal of these components must be protected by a rolled edge or    beading of minimum 3mm diameter.

  • Engine and gearbox breathing hoses and tubes, and the radiator overflow bottle vent, must exhaust into the airbox to the rear of the carburetor intakes. The lower airbox breather tube must be blocked.
  • Front brake caliper bolts must be lockwired in the tightened position
  • Oggy knobs cant protrude more than 80mm from the bodywork
  • Chain guard must be fitted to prevent trapping between the lower drive chain run and the rear sprocket
  • All lateral covers/engine cases that contain oil that could hit the ground in a crash have to have protection made of carbon/kevlar/solid steel to stop it spilling the cases.
  • Plugs and caps that may spil fluid if opened must be lockwired tight
  • Hoses must be securely fitted and guarded to prevent contact with the road
  • Only coolant allowed is water
  • Lower fairing catch tray to hold minimum of 3L (if the engine lets go) with 2 x 25mm holes which can be opened if its a wet race.
If anyone can see something I've missed let me know :-)


Cheers,
SammyA
