Enclosed a photograph of adjusting the variable altitude flap of the CR250-05.
To improve the torque in the bottom we have modify the valve data in consideration to the standard one. On the Dyno test bench we found that a measure of 12 mm between the lower part couple bolt and the siphon where the cable is on the right-hand side, gives the best solution. the photograph speaks for itself.
With adapting the cylinder and the flap on the bottom, the bike pulls even better
