The Cali. carb [mikuni bsr32ss} equipped bike does not run. You cannot feed 1/8 throttle in before it dies. I have not tested the non-cali model with the Mikuni tm28ss carb. As of July 22 there is no dyno jet kit out for either carb. I have tried rejetting and have had very poor results. I have also tried moving the needle with no improvement of throttle response. If you are in the market for this size bike I would suggest looking at a different maker.
