Affected:
62
Defect:
On certain motorcycles, the head of the rear wheel sprocket mounting bolt could break off and eventually wedge itself between the aluminum chain housing and the sprocket. this defect is due to a manufacturing process which may cause the bolts to become brittle.
Correction:

Campaign:
80V009000 on 03/06/1980
Component:
Service brakes, hydraulic:foundation components:disc:caliper
Manufactured:
09/30/1979 - 12/31/1979
Affected:
1,343
Defect:
The rear brake caliper casting on certain vehicles could be porous and could allow brake fluid to seep from the caliper assembly. if this occurs, the rear brakes will gradually lose fluid and pressure.
Correction:

Component:
Electrical system:ignition:switch
Manufactured:
09/30/1979 - 01/31/1980
Affected:
2,440
Defect:
There is a potential malfunction within the fork lock pin return mechanism which might allow the fork pin to drop and inadvertently engage the fork lock during left hand turns at low speeds.
Correction:

Notes:
Vehicle description: motorcycles.system: electrical; ignition switch/fork lock assembly.consequences of defect: unexpected engaging of the fork lock can result invehicle accident and personal injury.

Campaign:
80V070000 on 07/30/1980
Component:
Steering:column locking:anti-theft device

Affected:
3,860
Defect:
The adjusting screw, which mounts through a fork lock lever assembly into the fork lock itself, may not be fully and securely engaged because the screw may not be long enough. this may allow the fork pin to drop and accidentally engage the fork lock.
Correction:
Dealer will install an adjusting screw kit free of charge.
Notes:
Vehicle description: motorcycles.system: electrical; ignition switch; fork lock assembly.consequences of defect: the fork lock could be engaged, causing loss of vehiclecontrol, without prior warning, and an accident.note: the defect is likely to occur during extreme left hand turns at lowspeeds when the handlebar must be physically rotated to its left stop.

Campaign:
80V084000 on 08/10/1980
Component:
Service brakes, hydraulic:pedals and linkages
Manufactured:
08/31/1979 - 05/31/1980
Affected:
6,214
Defect:

Correction:
Dealer will replace the rear brake control mounting bolts and add a lock plate without charge.
Notes:
Vehicle description: motorcycles.system: service brakes; rear brake control, mounting bolts.consequences of defect: this condition may result in loss of rear brakingcontrol, and an accident.

Campaign:
80V085000 on 08/10/1980
Component:
Wheels:lugs/nuts/bolts
Manufactured:
05/31/1979 - 05/31/1980
Affected:
4,690
