I was curious if anyone was else was thinking about an engine swap to introduce E.F.I. to the bike and eliminate the issue of parts not being necessarily readily available. I was thinking about putting an engine and wiring harness from a FC450 or 450SXF 2016 or newer. The only issue I can think of is engine fitment and the lack of a fuel pump. Does anyone have any ideas or measurements from a new 450 dirt bike? I have some close approximations from measuring a new one at the stealership. I contacted IMS to see if they would build a tank with a pump installed and they declined. Any leads on other contacts for an original looking tank with some better inserts and a fuel pump ready to go? If this is a terrible idea please say so, I'm not looking to cut up the frame.

I'm glad I'm not the only one. I have my 450sx nearly down to the frame right now, do you think you might be able to take some measurements of the engine in your FX 450? I think my main concern is the height of the newer MX engines.
