Thread: Fuel Ratio?

  1. #1

    Fuel Ratio?

    I have a 2001 gp1200r and the shop just converted it to premix. They said 40:1.. Is that the best ratio? And also the engine has 2 hours on it. thanks

    some will say 32:1 some will say 40:1 so i went in the middle at 36:1. did they remove your cat and put a d plate also? if not you have to still use yamalube 2w if they did i reccomend yamalube 2s
