Dropped into our local Vespa scooter shop this afternoon and picked up a '2%
oil mix cup'.
Overpriced at $6.88 + tax and somewhat cheaply made plastic (had to smooth a
few sharp edges with emery cloth), this cup is very handy for quick oil/gas
ratio mixing.
It is marked for the metric system, US measurements and the old Imperial
system. note: geared for 50:1 mix
Although the new Vespas are 4 stroke, the counter guy told me all the old 2
stroke scooter owners have this cup.
