Heres a link that might be useful? Tells you to remove the air intake manifold washer restrictor. Besides that, you may have to up your jet size and make sure you have a smooth boss drive. And as for the cdi, im not sure if its even limited like the older models. I have the 2013 model and still haven't messed with it yet cuz im broke main! LOL, i'll get around to it someday?
