had the ty 80 out in a field learning gears etc and there is a large amount of oil running from the silencer and in the air ending up as black spots all over the wee lads back.

obviously the first thing I think of is mixture of fuel. Currently running at 40:1 motorex 2t fully synthetic

what is the proper ratio ?

best way to get exhaust cleaned out ?

any other ideas

are you running the autolube also?

Many times the cable is pulled but the pump still adds the minimum idle amount. So at idle it is double oiled.

I ran 60:1 in ours. Typical trials and kid use though. If winding it out along trails, maybe 40 is ok, but for trials it seems too rich.

If exhaust is dirty, it heats up and is very sluggish.

kcj

only running on premix, oil tank is gone

think i may need something put down the exhaust to flush oil residue out, not too sure (with it off of course)

seem to remember putting caustic soda down the exhaust of my moped 20 years ago, any ideas
