CBR250 engine is a good choice. Is there a California spec version or are they all? The reason I ask is that the California version of many of the older fuel injected bikes had an O2 sensor, meaning closed loop, meaning more efficiency.

What I would do is go to, look up the parts schematic for the bike in question, and see if it has an O2 sensor at all. If it does, then BAM!...that's a good candidate.

Example...check out this CBR250 breakdown. Item #11 is the O2 sensor. BAM!
