I did this:

Mains, 118
Pilots 40,
Thruxton needles.
I can get my airbox off in seconds, I can get my carbs off in under a minute.
Ridden it over 4,000km now and all over the rev range and in the rain and on +40'C days and had no problems. Definitely more power, and very smooth, plus it cut my 'back off pops' down heaps.
I'll get it dyno'd one day, but I was just happy to junk that cracked plastic wash basin they call an airbox for some steel!!!!
