    I should have said left side, or better yet the stator cover, sorry.

    You don't want to drain that oil where the crank is, you need some, the excess will find its way out after a few minutes of hard riding. If you ever rebuild a 2 stroke engine top to bottom you need to put some raw 2 stroke oil in the crankcase before startup. I can't help you on the jetting, sorry.

    He could do a leak down test to find out if his crank seal is leaking, right? By leak down, i mean pressurize the cylinder, block off the exhaust, and see if it loses pressure.

    yes that would be the best way to figure out if anything is going on in the bottom end however I'm not sure this guy even knows what a spark plug is so making a leakdown tester may a bit out of his league. I don't mean any offense but This is the internet and suggestions can be given but it is impossible to tell you exactly what is wrong with it.

    I do take some offense with that comment, I don't know anymore about you than you do me. You may be surprised at the projects I work on, the tools I have made and the things I have done that I was told couldn't. Like I mentioned earlier this is the first 2 stroke I have messed with, so I'm just trying to understand how everything works. All my other vehicles are 4 stroke. Would a leak down test pinpoint a leak or just let you know you have one? You would also have to seal the intake, correct? All suggestions are appreciated and I know its the internet so everything is taken with a grain of salt, it is always best to research as much as possible so you don't mess things up worst than before you started.

    . I have never built a leak down tester but got a hunch it will only tell you if something is sucking/leaking air (crank seals,jug and so on).
