I have recently fitted the Wiseco 904bb kit to my bike (04 TBA) and with the recent fair weather taken it out for a couple of rides. It has a Uni filter,no snorkels,TOR pipes and Thruxton needles. Main jets are 120 and pilots 42. Since the bb kit I have not changed anything. Plug colour is good and it goes really well but it does run a good bit hotter. Is this because it might be too lean and does fitting a bb kit mean that you need to up-jet?
I noticed on Pats calculator that there is no input for the bb kit. Anyone any thoughts on this?
