Bike only runs 5% throttle

Barely got home, anything more than smidge on throttle dies, backfires if i persist with stalling/stuttering.
Suspected fuel pump gummed up but surprisingly after 14yrs looked ok, needs replacing but do u think this was the prob?

Ok read the thread about bypassing the internal filter, didn't realise this was just merely a pre-filter - really not sure about the modding oem pump.

Any fault codes?

no fault codes. i really dubious about the ext filter mod, thinking I'll get a new Kemso pump & shake/clean the old black plastic filter assembly as best I can. If no good, then do the ext filter mod as last resort.

So few months back new $40 Kemso pump got me going, but only marginally better. Ordered new fuel filter for usd220 & put that in & all back to normal.
So my in tank filter lasted 55k kms, 14yrs, i always run prem 95ron.

55k kms is not really enough, is it? Should last longer surely.
