SO I am working on a Maxi for a guy, he could not get it running, It has a stock E50, 14mm carb with a 58 jet, BiTurbo pipe, stock air box. It had a 60 something jet in it but I could not read the little fucking number on the Bing jet and it was flooding out, hence the 58 jet. I get it running pretty good and I am taking it for a ride. I am cruising at WOT and the thing jerks and stalls, so I coast it home thinking it soft siezed. I get it home and it starts right back up. Later that day I have my son ride it and he comes home telling me how it was running fine and jerked and stalled. He started it back up and took it home.
Soft sieze? Ring sticking?
The thing 4 strokes just a bit on take off but I would rather it be rich than lean so I left it alone.
What does it sound like?
