Greetings. Just joined; what a great site.
My son just got a DB30 for his 9th birthday. I was really worried at first about the lack of power and I could see he was trying hard to hide his disappointment. Then we (i) adjusted the brake so it wouldn't drag; (ii) loosened the chain a bit; and (iii) backed out the trottle stop screw, and now it is perfect. Still a bit slow on hills, but that is just fine for a 9 year old learning to ride his first mini-bike. I did order the jack-shaft kit for a future upgrade. Overall, for $200, I am pretty pleased.
