exhaust oil

Are you using the stock oil injection or do you mix your own. The stock injection mix is about 25:1, I believe.

If the oil drip problem worries you, you can do a mod that allows you to mix your own oil/fuel to 32:1.

If you do that mod you will have to re jet the carby.

If it's going as well as you expect it can go, stick with what you got.
