Did you check the jet needle to see if anyone has placed shims under ? I was experimenting with shims and put them in in winter then when started riding I started noticing rich running symptoms after about 100km and my milage was poor: 18-20km to a litre. I removed them and it started running much better and the milage improved.
Apparently shimming is a very popular mod on 250r and many people do it and see improvements. Our zzrs are jetted differently and it looks like shimming make the engine running much worse.
