    Welcome to three wheeler world.

    Personally, i would re-connect the injector system if i were you. It really is no offense to you but if you arent sure what mix to use then oil injection sounds like its right up your alley.

    What some people do not realize is that the manufacturers are able to make to injection systems variable, so that the amount of oil that is injected changes with throttle input, so no matter what, you will NEVER find a mix that is pefect for those bikes.

    Now, people are going to post about they took their oil injection off 20 years ago and the bike still runs fine. This is very common and im not going to argue that, but some engine designs just dont like it, and they WILL be damaged from lack of lubrication.

    I had a blaster that they did the whole injection system removed. It's way easier and better for the bike to just put it back on. If you can find one cheap, replace it. People also say they don't trust them, I have never heard of one failing.

    But I would start around 32:1 and go from there. See where you need to be.
