Post My New 2009 Bws 50 Build
Hello everybody! I'm 14 years old and have recently bought a mint 2009 Yamaha Bws. I've since started tearing everything apart and have started to rebuild it for riding in my local city. My friends and I have a group of 8 riders all on scooters that put around and have fun. However, all of them have 4 strokes. (lmao) I've boughten all new parts such as an exhaust, intake, carbs, grips, plastics, Pirelli speed kit, and some other little things. The kid who had it before me had been t-boned by a drunk driver and is paralyzed from the waist down. (I feel horrible for him) Overall I hope to meet some new people on here and learn some new hacks and mods. I'll upload some videos and pics of my build and how everything is going. - Thanks, Devon

I'm curious as to how you are able to pay for all these things at the age of 14 lol. Nonetheless, start off by telling us all the new mods you have bought and the carb settings i.e. needle clip position, MJ, etc.

'98 Zuma Prebug

70cc Athena w/ BR9HS, 17.5mm Carb (82MJ, clip 1 from bottom), 9.9:1 final drive, 4.4g rollers, LV 5k clutch springs, LV TT Pipe
