4.5. Transmission: Chain and Bottom Bracket
Check the wear on the gear rim and
sprockets.
If you happen to notice that one of
them has sprockets in poor condition
(as indicated in the picture), go
to a Bultaco Motors Dealer for a
replacement.
Check the wear on the chain.
Periodically review the chain play. You
must pull it carefully as indicated in
the picture (for ease we recommend
doing this in the area of the chainring).
If in doing so you can see at least
half-a sprocket of the drive chainring,
go to a Bultaco Motors Dealer for a
replacement.
Clean and lubricate the chain.
Remove dirt from the chain after each
use. It is very important to maintain
a suitable level of grease by regularly
using appropriate products.
