'77 XS with K&N air pods

[jack455]

Hi guys. I bought an XS650 off a guy who has been playing around with it. It came with K&N air filters but runs lumpy. I'm told I need a rejet kit or possibly just different size standard needles. Can anybody advise? What size or where to buy a rejet kit? (preferably in UK but will post from US if need be)

Thanks in advance
