Welcome

Regarding mods, I went for PCV, Kevs O2 optimiser, DNA stage 1 and 2 and GPR exhausts and it made a good difference to the bike!

The DNA stage 1 and 2 seemed to totally changed the sound even on the standard cans so would recommend those.
I had already ordered the PCV before discovering Kev did a cheaper alternative, so probably worth checking that out.

I'm also going to need new tires soon enough and want to do the cush drive mod as im pretty sure mines worn.
