So i changed my mind about the whole stretch scooter out,i got back scooter last week,and this lil thing hauls ass for 50cc im very surprised,my question is whats some cheaper upgrades i can do to this thing to get better top end and take off,i want to put exhaust on but $$ is tight so i want to do a few sml thinhs first,like wieights,clutch(maybe) unlimited cdi and bigger spring, the carb is a 17mm or 18 (brand new) the mechanic did a great job getting her dialed in right,i still am amazed it runs cause my brother gave me scooter in piece(and i mean 1,000,000)pieces,oily hands if u can help me out let me know ive been looking at your site and yall have some stuff i like,just want to buy the right stuff,and im doing the rest of work on bike on my weekends off frm work thanks again!!
