I just purchased both a CBR600RR 07-09 pump (it was an 09 with 400 miles that I picked up) and a CBR600RR 09 (not sure what other years are the same) tip-over sensor on EBay for $29.99 each shipped. They should be here next week. Now I have the throttle body (with TPS), fuel pump, and tip-over sensor. Still to get are several additional sensors, a MegaSquirt, injectors, piping, fuel and air filters, etc. I also have to build injector manifolds and an air splitter. Might need to build a cam for the throttle cable as well.
Fuel pump found?
It appears that a Honda CBR1000RR 08-09 or a CBR600RR 07-09 pump might be the ticket for me. It isn’t an external pump but I could fab up something to put it in as a secondary tank. The unit is nice, small, compact, designed to put out 50psi, appears to have a built-in pressure regulator so that it’s already regulated when it leaves the pump thus negating any need for a return line, and has a low fuel warning sensor that I am sure I could find use for.
The CBR1000RR pump puts out about 1200 cc/min while the CBR600RR pump puts out 1000 cc/min. Both are above the 600cc/min that my bike’s existing pump is rated for. I wonder if the 600RR pump would consume less amps than the 1000RR pump. Both are priced about the same on EBay. The less power consumed, the better for my bike. The PC is already underpowered as it is. I need to be careful not to use up all the juice I rely on to have heated socks in the winter!
Exhaust bung for O2 sensor
Rather than weld in a special bung, I might be able to get away with drilling out a hole and holding the bung in place using a muffler/exhaust pipe patch along these lines: https://www.caswellplating.com/

Something like that looks VERY promising. And I could do it at home!
A bung like this https://www.diyautotune.com/product/innovate-motorsports-extended-o2-sensor-bung-3764/ or like this https://www.diyautotune.com/product/mild-steel-18×1-5-thread-bung-and-plug-kit-3735/ should be prefect for the O2 sensor.
Another option is a rivnut http://pc800archive.douglasvanbossuyt.com/message.php?message_id=100103
Still need to do research and select a proper wide-band O2 sensor… Looks like I’ll need to go for something along these lines: Yes, I’m willing to pay an extra $50 for a gauge to put on my dash 😛 Not sure if I want an analogue one or a digital one though. I’m favoring the analog gauge.
