The BF -7 model also has a second chain. This back chain is tightened as follows:
Remove the protective plate from the back hood. Make sure the hub remains exactly parallel
to the rear axle (maximum 1 mm difference in distance between rear axle and the small axle
of the brake hub left and right), as can be seen in the picture below (picture 7a). It should be
possible to push in the chain in the middle with the thumb for about 3-4 mm. After this the
front chain is tightened.

4.4.2 Crank assembly, when running in a new go-kart
After a period of use of a few days (of intensive use) to two weeks (normal use) the fixing
bolts (see Fig. 8) with which the left and right cranks are mounted, have to be tightened
again. Make sure that this is done 'hand-tight', i.e. with a maximum torque of 30 Nm. You
can also turn to your dealer. He will be pleased to do this for you. (It is a normal effect that
after a short period of use, under the influence of pressure on the pedals, the crank
assembly will set itself. An additional effect is that play can arise, which consequently can
lead to damage of the crank and the crankshaft. This play can be taken away by further
tightening the bolts).
