I have:

Ported head also milled and polished rocker arms adjustable cam sprockets.
Cylinder 3mm overbore 442cc also milled.
Crank lightened and polished -1lbs.
Rods lightened and polished.
Close Ratio Sp gear box. (Must have if racing)
Polished water pump housing.

Nourished with a fine set of mikuni fcr 33mm flat slides

I also own a 2007 fuel injected gsr400 motor that may end up in a 73 chassis someday.

I have

4 Really big pistons 1200cc
Head appears to be black and is quite clean.
Crank is at the bottom of the engine though with the engine pretty much laying flat that may be the back.
Rods were probably quite shiney when the engine was built.
Cassette gearbox (must have for car park quedos)
Once polished the bodywork then got bored.
Nourished by a fuel system that can drain 16 litres of fuel in 80 miles.

I also own a scooter which may end up in a hedge someday:D
