I finally took the plunge and bought a kit. Got the 65cc metra-kit and I well into the break-in. 50 miles so far and no seizes :) Now I have some fine tuning questions that I know you moped experts can help with.

First the setup:

1978 Newport with 15mm bing with 82 jet, high flow filter, a 15mm intake (the square bottomed one) and a bi-turbo exhaust. I have not ported/port matched my kit to the bottom end (I know that I am missing out, but the porting thing still makes me nervous)

Now the questions:

I know that most people think that bings just suck, but I have a 12mm, a 14mm and the 15mm and all jets from 56 - 88 so I really don't feel like switching. The problem is that the thing 4 strokes like crazy from 0 - 1/2 throttle, is happy and sounds great from 1/2 to 3/4 and then above 3/4 actually slows down. What gives? Do I set the needle different, or is my jet wrong? The plug chops look good after I have ridden a ways at 3/4 throttle and look oily after a ride at 1/4. Also, it starts right up and idles great when cold, but once I have ridden it a mile or 2, if I stop, the ped dies out, no idle no matter what. Is this jet/bing carb related too? Should I open up the bottom of my intake to round it out? Any help or ideas would be greatly appreciated.
