Pipes - Yep, i've got Short TORS on the bike (i suspect thats a lot less free flowing than normal after market pipes but i prefer the 'quiet')

For reference, K%N Pods are what i've been seeing on most bikes with battery relocated yeah? I've seen a few ebay 'Triumph America' K&N filters and they're totally round rather than tapered (like i assume the pods are).

Apart from losing the cheesegraters (which i'm happy to do) are there any negatives to losing the airbox vs opening it up?

The jet kits that Jenks does seems to be good value - though i've only seen Thruxton needles rather than TBS ones (from reading other threads it looks like the difference between the two is a debate in itself).

The guy doing it is an engineer anyway so he should be up on what he's doing - its just worth me making sure by buying one thing i wasn't giving myself more expense later on (i.e. by getting the pods, seperate bits etc i wasn't missing something vital from the Dynojet).

in fairness, the only real performance thing i'm concerned about is fixing the current underlying problem - any improvement in performance or look (mines fairly stripped down) is just an added advantage.
