From the factory it probably was 100/1 but the motors were having problems with lubrication then Yamaha revised it to 50/1.
Use 50/1.
Use 50/1.

You can at any time, have too little oil in the mix. RESULT: BAD to VERY BAD
Having just a little more than necessary.....RESULT: GO FISH

Better to mix more oil than less.

Look at the fuel inlet, there should be a little placard there that says what the mix should be. It may have a film or residue on it so you may have to wipe it down to see it. If not there pull the cowling off and look on the motor.
Mix 50:1 & go fish =D>
