What is involved in the general service of a Motorcycle, ie what parts
are replaced and what fluids etc are changed and the rough cost of
this.

Could you indicate the type of MC? Also minor or major servicing -- as
recommended by the manufacturer with regard to age and / or mileage.
The answer depends upon these details.

it can be any type of bike and it s a major service

Well, the price will vary enormously depending upon the type and make
of machine so I?ll hold back on this. I have always done my own
servicing so it?s not by the book and my costs don?t include labour.
Others could present itemised bills for their services though.

However, salient items which might be attended to in a major service include :-

Engine oil.
Gear box oil (rare).
Bevel box lube (if shafty).
Hydraulic fluids.
Engine coolant.
Oil filter.
Air filter.
Fuel filter.
Brake pads.
Disks.
Emissions check and adjustment.
Transmission sprockets and chain.
Tappets (unless hydraulic)
Headstock / swing arm / shocky etc bearing re-grease (if non-sealed type).
Legs refilled / pressurised.
Rear shocky.
Spokes (if spoked).
Wheel alignment.
Battery.
Tyre pressure.

So much depends upon the vehicle. Lots of other items will be examined
too and remedy advised if faulty. These too would come under the
heading of ?service?, such as tyres, lights, horn, silencers
(mufflers) and down-pipes. Indeed anything which the service agent
considers to be dangerous, illegal or on the way out.

Hopefully other people can post itemised bills.
