you can start with a 190 and a 48......but what i would do to get optimnum preformance is to pm ken on this board....(kenfused)....and get his carb kit. let him know what you are running and you will recieve a kit that is set for your bike! it was the best i have seen and is worth the few dollars. saves a lot of time in changing jets and testing. make sure ya get the ez screw also!!!!........disclaimer...i recieve nothing in turn for this plug, it is just one of the few things you can purchace anywhere and it works when ya get it!!!!
have fun and let us know how it goes!!!!
