Hi,
Just bought my kids a 1982 Kawasaki KD80. It idles beautifully and still has lots of power but it smokes quite a bit when riding. The previous owner premixed the fuel at 50 to 1. Also the crankcase oil was quite low when I got it. Thanks for any help you can give.
50:1 is a lil lean- if its low on crank oil more often it is the seal gone bad ,and oil from the crank seeping in the crank area,burning in the chamber as well as the premix oil-
when this happens youll be fouling plugs left and right
