Carbs or something else, maybe?

[Sannox]

Back after a week away on holiday, saw loads of bikes, grrrrr :-)

Anyway, just about to bypass the fuel pump so I have direct gravity feed to the carbs, if it runs fine, then it's the pump, not touching anything else yet, the next to look at will be the plugs, I know they are only 2k old but got to be worth a look, as I'm on hols, I grabbed my multimeter from work, my own, not works and will check the plug cap restistances, 13 year old bike now, original plug caps, hmmmmm, the air filter is spotless and seated properly, will post the results of the test blast/fart later :-)
