Fuel Injected CBR250RR?

The fuel injectors on mine seem to look a awful lot like caburettors to me

Bollox. An aftermarket efi system would cost a serious amount of mullah & I don't see that reflected in the price.
Do the new 250's today even have an efi system?

i smell something... oh its an ass.

I know that there are some guys in auzzie that designed and fitted a fuel injected system for their MC22 cbr250. Not sure how they got on though, last I saw about it was on the cbr250 forums a year or so ago.

waste your time and money get a two stroke if you want a fast 250.

So says someone who has probably never ridden a cbr250 in anger

There are quite a few FI systems available in kit form (although not in bolt on form yet) and they are generally pretty cheap these days. Also, quite a few hobbyists are making there own - its not that hard to do.

i have ridden many a 250rr in my days as a mechanic thank you
how hard would it be to make the computer that tells the injectors what to do i.e. injection duration and timing a mate if mine wants to put an injection system on his rgv the only problem is the ecu and what sort of duration ect to use

Not much use on a two stroke, HRC tried it with the NSR500 and ditched it as it was a pain in the ass to setup. Injectors would also have to squirt the oil into the cylinder too, im not sure they'd be up to it.
Some new 2 stroke scooters use direct injection (straight into the cylinders) but they've got lots of R&D behind them.
It'd add too much weight and complexity to such a simple bike, you'd probably also seize it about 20 times while you set it up.
