Update. Moped is running very good, thanks to all you guys and your valuable pieces of information.
Did a good test run on Saturday. 38 Mph top speed on flats (GPS)
Max temp 290°
Main jet 70 and second notch from bottom.
Take off is still slow and still Bogs downs a little but it got way better. I'll keep playing with the needle, perhaps make it richer.
WOT it's good I'm guessing it is a little lean since it does not four stroke at all when I cut the throttle down. But temp seems to be good, I'll do a chop read to be on the safe side and adjust.
In any case this thing is good to go, I need the space for my next project.
