The CBR250 box may well look the same but trust me one this one, it's not an RC valve control box.

If you're on about the ones on ebay (items # 270328977900 and 280290440169) they're both clearly visable as KV3 parts and are from an NSR250.

I have no idea what the 2nd box is in auction 270328977900 but the part in auction 280290440169 is an RC valve control box.
As the part numbers are the same (mc16 and mc18 both list 31800-KV3-003 / 013 /023 /033) personally for the sake of £40 I'd buy item 280290440169 and try it. What could possibly go wrong?*

But that said I did plug in an RS PGM, use the biggest jets I've got and took it out in the fast group to check it worked, so what do I know?


*this is what I'd do, it's not advise on what you should do, do not blame me if/when it melts your loom, PGM or just flat does not work.
After all this seller is selling one along with something else for a "CBR250 mc18", it's safe to say he hasn't got a clue what he's got and certainly hasn't tested it or removed it from a working CBR250.
