Downtown 300 / Re: Hesitation during hard aceleration

Usually there is a sweet spot that one needs to find by moving the MAP sensor in either direction in small increments. Then test ride the scooter and see it it got better or worse, and find the best position. It's usually trial and error until one gets the best result.
My DT has stalled after a warm start I just give it a little throttle when starting and its OK and doesn't stall during operation.
