FRONTWHEEL Removal - America
WARNING: Before starting work, ensure
the motorcycle is stabilised and
adequately supported. This will help prevent it
from falling and causing injury to the operator or
damage to the motorcycle.
1. Support the motorcycle so that the front wheel is
clear of the ground.
NOTE: Provided that the front of the motorcycle is
raised sufficiently ,it is not necessaryto remove
the front brake caliper to remove the wheel.
2. Remove the front wheel spindle bolt.
3. Slacken the wheel spindle clamp (allen) bolts on both
forks.
4. Support he wheel and withdraw the spindle.
5. Manoeuvre the wheel out from the forks collecting
the speedometer drive as you do so.
6. Recover the spacer from the right side of the hub.
7. (My bit) Take front wheel with the flat tyre to the dealer to get fixed or tyre & tube replaced.
8. Good luck.
