Maintenance
The Titan ZG 45PCI-HV requires almost no servicing. If your engine is difficult to start
after the hibernation, suck fresh petrol into the carb to loosen the thick oil left after the
petrol has evaporated, and let this stand for a few days and you will find the engine
will run again without any adjustment of the needle valves.
Never use compressed air to clean the carburettor. Never remove the fine stainless steel
gauze filter in the carburettor for any reason. When you have followed our advice and
fitted a cotton felt clunk filter, there will never be any dirt in the carburettor, but there
may well be fine cotton fibres over the small gauze filter (this is the sole reason for this
filter). You can remove these fibres carefully with a toothpick, or tweezers.
If you wish to check the screws on the engine for tightness, please use the following
table showing torque settings. Especially critical are the four cylinder retaining screws.
These must never be really „pulled down“, otherwise the cylinder gasket, which is fairly
thick, will squash at the corners of the cylinder flange, causing the flange corners to
bend down and resulting in distortion of the cylinder. Cylinders so over tightened will
be difficult to turn through BDC when hot and will not be able to run at a low tickover
and will have considerably less power. This easily can happen with owners who having
just purchased a brand new engine and having nothing better to do than to really pull
down all the screws, the cylinder will then be useless scrap metal. If you do not have
a feel for tightening down screws or do not posses a torque wrench, then it is better
and cheaper, you leave them well alone.
