Hello l bought a 96 kx 125an estate sale, the bike was in good shape so l had it rebuilt at my local shop l picked it up yesterday and it runs great. The gas was already mixed (in the tank, from the shop) l forgot to ask what ratio l should use with Klotz 2 cycle oil. Thanks

most are 32 to 1

The 1990 model uses 32:1 although other models use anything between 20:1 and 40:1. See if you can get a Clymer manual for it or go for 25:1 to play safe. If the plug starts to get sooty then back off the ratio.

Kawasaki recommends 32:1

if it is klotz bean oil or non synthetic, l would go 20:1. if it is synthetic then l would go 32:1 to 38:1.

yes 32 to 1 with good 2 stroke oil. dont ever use 2 stroke outboard oil.
