I forgot to mention i also installed a performance cdi box with no rev limiter. So besides Ported straight pipe,no filter (Temporary), CDI box,jetted, and NGK plug its completely stock. Im a heavy rider about 250lbs so does 50mph topspeed sound right and why cant i get my rpms up above 7000? Im thinking its in my CVT since its not been touched although i did weigh my rollers last night and they are 13g. I couldnt ask for better take off but i would like better mid-range/top-end.
