79 Yamaha g1
I just bought a 79 Yamaha G one it was running rough so I replace the fuel pump and the carburetter it runs pretty decent but I noticed my exhaust at the head is dripping a little bit of oil wondering if that’s because the fuel mixture is too rich or am I getting too much fuel the oil injector it’s not hooked up at the moment I am mixing fuel for it right now

Re: 79 Yamaha g1
What oil are you using?
What ratio? Could be a head/cylinder gasket issue, might try checking the bolts. |

Re: 79 Yamaha g1
Stock mixing ratios are between 150:1 and 300:1 depending upon rpm and load according to the manual. I had lots of luck mixing at 125:1 with Echo brand synthetic air cooled 2 stroke oil that has an ethanol stabilizer. If you see oil leaking near the cylinder gasket then it's either a bad gasket, not torqued down enough, or too much oil in the fuel, or some or all of the above. Your carb could be running too rich also.

Re: 79 Yamaha g1
I’ll have to take a closer look exactly where it’s coming from but when I put my finger at the bottom of the exhaust pipe where it joins the head manifold that’s where I’m getting oil on my finger I had the exhaust pipe off at one time to do the barbeque burn and when I installed it I did not notice if the rings were good and not
