50:1
It should be oil injected with a separate oil resivoir.
what is the oil gas mixture for a ysr50
20:1
32:1 gas to oil mixture
The gas oil mixture for that sled is 24:1 according to the tag on my 79 srx.
The fuel mixture for a Yamaha 40 hp 2 stroke outboard engine is 50:1, gas, oil mixture. You should use new gas when you get the engine ready for the season.
the mixture is 50:1 I would use synthetic oil
No it is a 4 stroke
the safest mixture would be 32 to 1
40 to 50:1 with Yamalube
i have a 1985 Yamaha yfm 200, it is gas, no fuel/oil mix needed. just put in 93 octane. unless u have a 2 stroke then its usually a 50:1 or 40:1 mixture
there should be a flat switch beside the cover for the gas cap, and the ignition switch. That is your choke. Sticking up is full choke, down is choke off.
