Yamaha G1 Starts Up Great But Loses Power and Sputters Under Acceleration


Glad you are getting things figured out. it is fun tinkering for sure. Seems like your only question left is the oil out of the oil pump. I can't answer that as I took the oil pump off of mine, but I would say that if there is oil coming out then that is a good thing. Slight smoke tinge in the exhaust is what you are looking for, from what I have been finding out. Good job on your trouble shooting.


Thank you WallysWorld and HotRodCarts! It’s has a little oil coming out while running. To play it say I added oil to fuel as I would hate to fry the new piston and rings. Has a small tinge of smoke coming from exhaust. So feeling good.
