I know the barrels will fit straight on because I have it the other way round...1UA barrels on a 31K.
The 31K are more desirable as the port timings are slighly different and make them better for tuning purposes I believe.
I'm fairly sure the exhaust port timings are different and possibly the transfers, but I don't think there's a great deal in it.

I've got both on mine - 31K barrel one side and 1UA on the other. They were tuned as a pair so all ports are identical now on each barrel but it might take some explaining if I try selling the bike  |

Mark, paint the 1UA side as the later colours and decals, no need to explain after that |
