    I have several issues with my first build. I'll post about them separately to keep the topics separate. This one is about my oily exhaust pipe.

    The bottom part of my exhaust pipe, the part nearest the ground, has oil on it after every ride. Not much, just a thin layer. Is this normal, or is there something that needs to be corrected?

    You do not want all your oil to burn as you want some to lubricate. If all the oil burnt your motor would not last long. Yes this is normal on a 2 cycle.

    No matter the oil ration you will always have some oil coming out the of the exhaust. My marks its spot every time I park it.

    I run 40:1 and I get residue around the muffler end but I don't get any dripping goin on.

    I run 25 or 36 to 1. I sure hope you took the motor apart and cleaned it out well if you are going to break it in on 40 to 1. I think why most recommend to run it so rich with oil is they put these motors together in a sand box. Both my eBay motor and my Grubee had WAY TOO much trash in them. You could even see the shiny metal shavings along with a bunch of grit.

    Nope. Filled er up and took off. What you said is probably true but I aint got time for that :D I'll probably pay for it later on.

    Inside of my Grubee and this was just a small part of what was in it. All this wiped out and was very gritty. But some do not have a clue as they thing it is break in oil. I do not want grit going throw my motor.

    So you took it ALL apart and checked it? Both my eBay motor and Grubee had way too much in it. I will never run one of these motors without taking it apart.
