The reason I started this was due to popping on deceleration!!
I had stock 120's 42's and paper filter but TOR's.
I tried to adjust the idle but to no effect.
Removed the snorkles and got loads more power but more popping.
Thought I would change the setup for more power hence the Thruxton needles.
i think I'm almost there. I just need to sacrifice a few more virgins and I think i'll have it.
Thanks for the help,
Jon
