Hello, my issue is that the bike doesn't have any power until you get going over around 10mph or so. Below that, it bogs, hardly wants to go at all. I've played with my needle position and jets. After you get going it has a point where it suddenly sounds like it opens up and is happy and then you can really roar to about 47mph or so. But that starting off is so weak, worse than when it was a stock 50cc for sure. Sometimes it even just doesn't want to go at all and will stall out after it gets warm. My head temp reading is typically 300 or so, moves around that.
Most people keep saying timing, but after doing the micrometer, I just feel doubtful I can get it any finer, but I'll try adjusting it if that's really the most likely issue.
Ideas and suggestions?
