I see a lot of posts where people bypass the oil injection so they can just premix the oil and gas together. What is the purpose of doing this?? I'm getting an oil injected moped with the tank under the seat, is it dangerous to have it like this or what's the deal?? If it is, how do you bypass it?? Or does it improve performance or prevent future problems if the pump were to stop working?? Any tips or posts appreciated. I want to do what is safest to prolong the life of my engine and keep it in good condition. Thanks in advance!
