Dread loss of acceleration at low to mid range

[celticdog]

You said wet weather, my bad.
It can cause all sorts of weirdness, as i've found simply washing the bike with a jet spray before.
What is your version of "loss off power" though?
Spluttering, bogging down, jittery, bit more info needed?

Yep it's been torrential the last two days here. I'd say it's more of a bogging down but the engine doesn't want to cut out at any point. I'm riding to work tomorrow so I'll get a better idea of what's happening.
I'm hoping I don't have to touch the carbs, i'm of the opinion they're best left alone unless absolutely necessary
