That looks the same as mine, though thats a chinese copy, not a genuine Keihin.

Hi,
I have a few questions.
any updates on the carb conversion,
how does the engine work with it?
any other mods or conversions you had to do in order to work properly? for example the fuel tank or the ecu or any other part?
I have the same ec400 and altho the engine works ok on idle or full throttle some times is a little hard to start no matter if the engine is hot or cold and stalls on low revs when I close the gas.

any help is welcome
thanks in advance!

At that price - I agree with homer that it isn't a real Keihin... Doing a search on "fake fcr 39" or "chinese fcr 39" finds some interesting info...

...and probably much more trouble than it is worth...
