I am about to do the following mods to my 07 TBA.
Long TORs
AI removal
Drill arbox, remove snokel
and rejet the mains with 130s (as per Pat's calculations)
I know that I will be pretty close to dialed in but, will want to check the plugs following the changes. Question is should I take out my old plugs and clean them then recheck from time time or just start out with the new plugs?
