another light load issue

[Pommie]

maybe lean area due to fuel pressure or mapping, ???

I've reset the tre to its default. Just taken my old fuel pump to bits and flushed the filter. Gonna try putting that back on tomorrow. Bike is at work so can't test either til later. Going to put a fresh tank of fuel through it and try some injector cleaner. Can't do any harm. If it improves with clean fuel filter then I'll put a new pump on it. (not expensive anymore of eBay) What adhesive is best to put the end back on filter housing??
