What Keith said
It sounds like You and I are at about the same stage with performance.
I have a K&N filter,no snorkel,AI removed,re-jet,1 shim on the carb needles,after market pipes
I just came back from a 400 Km ride yesterday.
I was thinking at times "This is GREAT!".Other times I was thinking,"If I had just a LITTLE more Oomph"
I got 18k per litre and if I want more"Oomph" I'd probably lose some mileage[kilometreage?]
[I think "Oomph" is the technical term,not sure]
