1.5-2" Inlet Motorcycle Exhaust Muffler Slip On 400mm Lengthened Universal for Dirt Bike ATV Street Bike 38-51mm Inlet with DB Killer Silencer HTRACING (Grilled Blue)

i put a set of pirelli tires on mine, i swapped the 10" rear for a 12" rim/tire. this alone should get you about 10% more speed. for a bit more pep off the line i did swap to 13? gram rollers https://www.amazon.com/dp/B0DYPX1B41?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 in the variator.i have also swapped in a nibbi 22mm carb https://www.amazon.com/dp/B01MUGRH44?lv=shuf&channelId=500&plpRedirect=mhFallbacka lowering block, because along with being "robust" i am a bit short https://www.amazon.com/dp/B0CWRW2Y62?ref=ppx_yo2ov_dt_b_fed_asin_titleI also put on a gy6 150cc exhaust https://www.amazon.com/dp/B09FLCTHCQ?ref=ppx_yo2ov_dt_b_fed_asin_title https://www.amazon.com/dp/B095XZL75W?ref=ppx_yo2ov_dt_b_fed_asin_titleand because its light enough i can pick it up an carry it i slapped a annoyingly loud alarm on it https://www.amazon.com/dp/B0DY75ZGBH?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1for the rear tire i used https://www.ebay.com/itm/377028741485 pirelli 120/70-12 and a stock front rim https://www.ebay.com/itm/306846269849 which can have the hub swapped out "4 bolts" to fit the rear. this tire WILL require some trimming, a pirelli 110/70-12 should only require a little trimming of the muffler mount. with my 210lbs on it i get about 52 mph and about 70mpg, im still tuning the carb and im not very aerodynamic. i also swapped to a fancy digital dash, while it looks cool at night its impossible to read during the day so i will be swapping it for a different type at some point.
