Piaggio Zip 100 (4T) awful fuel consumption

Hi everyone.

I have recently purchased a Piaggio Zip 100, good condition, low mileage, well looked after.

It's working fine except it's burning twice as much fuel than it should. My current fuel consumption is 6L/100km or 47mpg which is far from the expected ~100mpg. The scooter is bog standard. It's using more fuel than my GSX-R 600...

The scoot runs fine, no fuel leaks, always starts on the button, idle is a little bit high, that's all.

I would highly appreciate any help. Thank you again.

 

What do you mean? The Suzuki is being used as a good weather weekend bike, zip does the rest (shopping, getting to work etc). All my friends are doing the same thing.

 

Same here, I use my sons 50cc for shopping now - bigger bikes for runs out in the summer.

When I first got my sons scoot going - it was eating petrol, even a local test ride would result in a visible movement of the fuel gauge and it would empty the tank in no time.

Fiddled with the mixture screw (it's explained in this vid),



Reset the idle using a portable tacho, now much better.

So try that first and see where you are.

 

Thank you. Is it the same for 4 stroke scooters?

 

It's the same process. Often what happens is people fiddle with the mixture screw to get a bike started and then leave it at a less than optimum setting. If you can get the factory setting say 2 or 2.5 turns out from lightly seated (or whatever it is), that will give you a good start point to set it.

Plenty of people here will help out if you get stuck, or if it makes no difference to fuel consumption setting the mixture screw and you have to look deeper into the problem It's the best place to start though.
