Great site,I,m new to this site, computers and a thruxton.Like most I am after a bit more noise and the bit of extra grunt that goes with it.
So it seems basic, better air flow in, better exhaust out, but what about the stuff in between?
I am trying to keep it bolt on after market simple, couple of questions,
is AI and NARK the same thing?
Both thundebike and staintune say you don,t need to rejet yet there is a lot of discussion about jetting.
Whats the go with the nology ignition coil @ newthruxton( for the middle bit)
Pods and K@N filters, do some of the AI or NARK require you to be air filter specific?
I imagine that all this has been hashed out before, thanks

Welcome and congrats on the Thruxton. AI is Air Injection, referring to the system that supplies air to the exhaust stream to promote additional burning of exhaust gases for cleaner emissions. NARK is New Bonneville Airbox Removal Kit, which I think is self-explanatory. Removing the airbox and adding pod filters go hand-in-hand. If you install free-flow mufflers you will most likely want to install a NARK, or at least remove the snorkel and use a free-flow air filter... this WILL require larger main jets.
