Alright guys, need some help. I searched but couldn't find exactly what I need.

I am working on my buddy's millennium GPR. It is bone stock with the exception of waveaters and a solas prop. I plan on pulling the carbs tonight to disable the accel pumps and rejet to the recommended 110/120/1.5/95 setup. Question is: Is that jetting OK for a bone stock motor? no F/A's, stock comp., ect. Also, some recommend a 125 main. What would you do?

Right now there is no wash on the pistons, so I know somethings up. Compression is good at about 120 per hole. He is just looking for reliability right now.
