Nath,
 
EFI version of 140 RX has been discontinued last year.  
Midrange problem was solved at least 4 or 5 years ago by OS.  I believe new
mixtue control valve was used.  Not sure since it's been too long since the
change.
Make sure to get Rear bearing for 140RX EFI. (OS part # 29430010).  Replace
the rear bearing of the 140RX.  Stock 140RX rear bearing doesn't last long
enough.
There wasn't any other changes to the engine since the engine runs well.
For the setup, check the link below.

Hope this helps,

Hey all.

Am about to finally get the engine for my new project after many discussions
about what to get.Im going for a brand new 140rx(non FI) and was just
wanting to know any feedback about the engine before i buy. I have heard the
mid range problems have been worked out as far as going rich.........? does
this sound right? Does any one know how they have done this? Is there any
tricks to getting better linear throttle, eg plug, pie length etc and
finally has anything acturely changed with this engine since its beginning
in the 90's? technology wise......eg new pump,carby, needle, mixture control
etc.
All help appreciated.
