Hydraulic Brake Plunger Pin Adjustment
IMPORTANT
It is critical that the master cylinder pistons are adjusted properly when the steering
handlebars are in the centred position. Overheating of the brake system could occur
due to the piston being adjusted too far in. This could cause a drag on the system and
a possible brake lockup or brake fade. On the other hand, the piston being adjusted
too far out increases the distance the piston is required to travel to provide brake
pressure. This can result in the steering arm contacting and/or bending the plunger
pin guide tab resulting in compromised system operation.
1. Remove the rewall.
2. Loosen the set screw securing the collar to the plunger pin. Photo 59 This will free the
collar to slide along the pin.
IMPORTANT
Both left and right steering arms should be back to their rear most limit before the
plunger pin adjustment is made. Photo 60
NOTE
750 EFI and 700 models also require that you loosen off the hand brake cable across the
two steering arms to ensure they are back to their rear most limit.

3. Sitting in the vehicle driver’s seat, ensure that the steering handle bar is parallel with
the dash. Plunger pins should be in contact at the back with the steering arms. Place
the collar tightly up against the welded tab stop and secure the set screw with blue
LOCTITE 243.
