New Yamaha zuma 125 Fi, tuned by RRGS

This is my new project, the new zuma 125, these are made in taiwan and have been here for over 6 months, the engine itself is nothing new and has been kicking about for over 4 years, the amount of tuning parts for this bike is just mind boggling!. Alot of you americans are worried about the tunability of this new fuel injection engine and you should be, but fear not we have many kits that can take this bike to 230cc and over 30bhp!. Stage 1 tuning alone gives it 18bhp with a 155cc big bore kit,exhaust and big valve head. please visit www.smellybumlove.weebly.com for more info
