Genuine Yamaha manuals are currently out of print at the Yamaha
website. Here's a link to a seller that claims to provide a
new copy:

http://www.repairmanual.com/catalog/LIT-11616-XJ-70

And here's a used copy for sale on ebay:

There are also numerous new copies of the Haynes manual for this
model on ebay:

Sorry, don't know where to find an illegally copied electronic
version for you.

The bike should be fitted with a vacuum tap thats shuts fuel flow off when
the engine is off.

The float height should be 17.5mm +- 0.5mm to give a fuel level of 3.0mm +-
1mm.

The bike -MUST- be perfectly level across the carbs before checking the fuel
height.

That's 3mm, plus or minus 1 mm from the TOP of the float bowl.

This level is measured with the carbs mounted on the motorcycle. A
short length of clear plastic tube, like aquarium air line, is
attached to the bottom of the float bowl at the drain plug. The open-
ended tubing is held up beside the top of the float bowl, and the
measurement is taken as the gasoline seeks its own level.
