Installed it with the tutorials on Youtube,great part.so far so good,increased my power .Make sure you do your research if you want to put this on.You need a good amount of other parts, assembly for installation.
Its awsome...Gives my moped allot of power and speed.Love it....I will be ordering more as long as they sell it!!!!
Put on my taotao racer 50 50cc moped for a little more power and got exactly that. Fit perfect and works very well. I am gaveling aproblem with it warm starting but that's my fault as I dropped the carb and messed something up.
Fit very well. Everything needed for the job was included in this kit. Would recommend to others.
Good.
