Answers:

Any recommendations for somewhere in central to east London that re-chromes motor bike engine parts.?

Some people her just making it up as they go along. The answer is the carbs could leak internally or externally. Leaking internally will flood the engine. Externally will have gas on the outside of the engin and the ground. Doesn't happen as much as it did 40 years ago.

Prevents the bowl getting full and it and other lines from leaking just from sitting around.

The main reason for turning off the gas is that when gas dries up it leaves a residue that is alot like varnish.After awile, it coats everything in the carb, and makes it run rough.It can even cause you to get poor mileage and sometimes even make the float stick and gas will run out all over the engine and may even cause a fire. Not a good thing while riding.

What is the name of bike which is in the film 'DHOOM2'?

The short answer I always give is not to turn it off..If the bike will be sitting for a week or longer yes,any shorter than that dont worry about it.A week,or even a month is not nearly long enough for gas to break down and "varnish".If there is gas running out of the carb bowl that is a problem that wont be fixed by turning off the gas anyway,a float problem no doubt.

What is a good used beginner sporty motorcycle for a tall (6'6") guy?

Safety measure. If the petcock vacuum shut-off fails and you have a float valve stuck open, you can flood a cylinder and experience "hdro lock". It can cause expensvie damage.

What do you people think of the new Ducati 1098?

Hydrolock is not at all uncommon. Been there myself.

I wanna buy a Yamaha YZF-R1 (2007)!!?

Was biting my tongue until I got to bluff_michael's answer. It's a safety measure, and old practice. Before vacuum operated diaphragms in the petcock it was just a valve. I didn't get hydrolock on the '74 because it came out the vent tubes. Softened the tar so the bike fell over. On the '82, I was lucky, the airbox was lower than the cylinder. Held 1/2 gal.

bazaz any new bike coming?

So don't forget.

hay, read the owners Manuel, it's your bike. I found there are no shortcuts in the mechanical area that don't eventually lead to a larger problem
