I know have Thunderbike pipes and K&N air filter and I was thinking of re-jetting.
What is your opinion, I used calculator at dinqua.com and with current setup I should go with 125 main jets with Thruxton needles (want to put those in too) and I was wondering if I want to do something with the airbox (Polaris bellmouth etc. etc.), should I go with 130 jets instead without running too rich??
I´m totally new to re-jetting so I would really appreciate some help and opinions. Thanks.
