Hi .My son has a 1985 KX80 e3 and it runs well but the gearbox oil seems to disappear from the box and end up dribbling through the exhaust pipe as a black gunge and covers the right-hand side swingarm. I know the cylinder is a sealed section , is the oil making it's way in and if so where, is it the crank seal? For that is the only thing I can think of, for the oil to make its way through to the exhaust pipe. The bike starts well and runs well so it seems it is not burning the oil. Does anyone have an idea which will help. Thanks Robert -- Robert Harrell INIT Mobile Computer Services www.init.com.au 0403511278 0266795589
Having been down this road before.... Don't spend any money on a 20 year old bike. Keep putting oil in it until it stops working, then bury it in a big hole...
hi there is a way to test the crank seals.put castrol R in the gearbox after draining the oil out.if it is burling the oil from the gearbox you will be able to smell the R burning. jimg
Thanks you guys I think I will ignore the first comment being a vintage cycle enthusiast. I think the seals also. Thanks for the help. Cheers Robert
