My '81 YZ465 calls for 32:1 premix with premium gas (90+ octane). I use 40:1 Golden Spectro with no problems. Modern synthetic 2-stroke oils have better lubricity than the old oils, so higher ratios are usually okay. Bill |

I use Golden Spectro at 50:1 in everything (1 small bottle to 5gals of premium pump gas) I have. CZ 125/250/400, Bul 350T, Rickman Zundapp 125, Montesa 250 King Scorpion. Always have great wear resistance and rarely/never have spark plug fouling. From my experience it is best to run the oil manufacturers reccomended ratios as most vintage stuff only had prehistoric oils to draw from. OriginalDirt |
