ok well your jetting should be fine. you probably just have a leaky crankcase seal.

does this continue say for more then 10 minutes.

oil is pretty much constant but worse then other at times was at 1 and 3/4 now at 1 trying to lean i am on second clip when you first fire up seems great till you put in gear and go rpms r up it doesnt mess around but before changed oil would check ride couple hours come home and check and oil in tranny would be lower like it was sucking it up and blowing out of exhaust

so will crancase sill cause you blow oil and allow you loose it out of tranny?

i dont know, i know that one of the seals are leaking. i am not really that good with all the engine seals cause i have never had that kind of problem.
