ok guys I've thought about it long enough and I think the first option I need to explore in my quest to make my bike better is to convert it to a FI setup. I have been told that an 03-04 636 FI system will work on my bike. The question is what all do I need to take off an 03-04. Im trying to make a list so I can see how much it'll run me. So far I have: Throttle bodies, Fuel pump, wiring harness, Computer, Injectors(should be part of the throttle bodies), and I'm not sure if I need the different airbox or not, or if there is an emissions setup that I also need to get for the ECU to work properly. I know I'm leaving out a ton of parts, I was wondering if anyone had done a similar conversion and knows what all I'll need. Thanks for the help guys.

 

get a frame and sum wheels you got a new bike...lol j/k bro it just sounds like an awful lot of work. imosorry im not much help

 

I like challenges though, and I was checking for the most part it looks like if I can get a complete wiring harness ( with all the fuses and relays) that the electrical is not really a problem. There is no emission system in the exhaust so thats good, but the one problem that I found is that on the 03 the fuel pump is in the tank meaning I'll either have to get a new tank or try to modify mine.

 

or used an our of tank fuel pump that can pressurize to FI pressures. like walbro's new inline pump. you'd probably need to get an aftermarket fuel pressure regulator and plumb the return line back to the tank.

 

You'll need the whole wiring harness, ECU& electrics of an 03-04 to make it work. You'll need an airbox because the IAt sensor is mounted on it or if you can install one on yours being that the Ram-Air tubes are on the sides.
