What is the oil ratio for a yz250?
My YZ 250 runs at 32:1 which is what’s written in the owners manual. If you don’t have an owners manual, consult your local (Suzuki, Yamaha, KTM etc) dealership and ask them. A lot of riders run their bikes at 40:1. If you aren’t pinning it everywhere you will get away with this.
