I was wondering if its the same FI system that is on the ninja 250's from over seas. Anyone know? if so It will bring down the price of converting my 250 over to oem FI :)

I'm not sure if anyone has conclusively confirmed this.

There's a group buy on the Ecotrons EFI kit, it'll be $450 or so depending on if we get 4 more people. I highly doubt even the stock throttle body could be bought for that price!! plus this one is fully tuneable with a laptop

oh God... I decided to check on old posts and I see there has not been enough feedback in some cases...

250's european, brazilian, asian '08-'14 models have 28mm TBs with 200cc/min injectors and a tiny 18mL/3sec fuel pump...
300 has 32mm TBs with 175cc injectors and an improved 45+mL/3sec fuel pump
the 300 factory system (TBs and FP) can be used even on unmodified 250s but also have to get the ecu and harness for it...
