For CJ750 the mudguard has to be fastened exactly as with old M72 motorcycles

Up to 1951 - Old version - 3 points fastening.

Assembly:

We ask for the two sheet metal sleeves, where the ones with the fork brackets Screwed (thread), with Loctite 542.

It is very important, since the sheet metal sleeves are not the best quality and it can occur that start to lick

The shaft seal should also be checked if these are exactly in the sheet metal sleeves sit.

These must not move freely in the sheet metal sleeves, since oil can leak there as well. Before starting the first shock -

absorber assembly, do not immediately tighten everything.

You should before the first drive the bolts of the fender, under the bridge and of the axle slightly so that the shock

absorbers can sit.

Only after the first drive you can tighten all the screws.

Our valves have 2 holes as standard.

Depending on the weight of your  motorcycle or whether it is moved by sidecar or without, adjust the valves

responsively.

The adjustment is made by additional holes. The holes are characterized by a sin.

We ask you to tighten the oil - ee image

Maximum 2 additional bores depending on the motorcycle weight can still be done per valve
