qt50 cdi unit

Postby bigdog456 » Thu Sep 23, 2010 1:16 am

i have a qt50n. my cdi unit has a 4 wire plug and a single pig talil. all the other qt50's other than an n modle have a 3 wire plug and a single pig tail. when i'm riding and get to about 30 mph or so it's like a rev limiter comes on and the power goes away. i've been told to get a cdi from a yt60 because it has no rev limiter. the yt60 also only has a 3 wire plug and a single pig tail. does anyone have a wiring diagram for a qt50n or know why this modle has a different cdi than the others?

there is no rev limiter in a qt cdi nor a yt/yf cdi, all are identical inside. your oil pump is pumping in too much oil. read the book. adjust it.

The oil pump has nothing to do with speed, if you have a gy-6 engine my cdi was replaced.
Some people dream about speed! blink and im gone!
