Transmission chain lubrication
The drive chain includes lot of parts to jointly work.
If maintain improperly, the parts will be worn rapidly.
So, periodic repair should be conducted. If a motor-
cycle is running under rich dust condition, this repair
is very important.
1. Any brand of spray lubrication oil can be used.
Remove all the mud and dirt attached to the drive
chain with brush or rag, and then spray the lubrica-
tion oil.

move it from motorcycle and immerse it into solvent
and clean. Then take it out, dry and lubricate it
immediately to prevent it from rusting.
