Theres no point you spending the money to get it to run right, if you just bought it new from a dealer and its not running well then the dealer has to either fix it so it does run right or give you a new scoot. Why wont he fix it now? If its running crap then its his duty to fix it for free since you just bought it. It must be faulty or have issues from new which is unacceptable. I wouldnt do anything till he fixes the running issues, after that its easy to derestrict it yourself or have him do it even but get it running right 1st before you start tryimg to tune it, otherwise you will have a total nightmare trying to get it right.
