Yamaha Enduro 2 Stoke 15HP Not Running too well?

"is now running on fresh fuel with the correct 50:1 mix"


Hhhhmmmm... my (2006) Yamaha 9.9Hp two stroke asks for a 100:1 mix.
I don't know if all the Yamaha's are created for the same fuel/oil mix but I know for sure that I did once mix a 50:1 (don't ask...) and the engine did run "rough" and didn't like it at all.
Maybe your problem is as simple as this?

Good old Enduros still run a 50:1.
