Seeing as the stock exhaust (it was the cat type - weighed a ton, with all sorts of ancillary pipework attached), needed replacing, I've opted for a trusty SIP Road 2. In conjunction with fitting this and to add a little 'pep', I'm considering fitting a PX 200/drilled-out air filter, but am unsure where to start with the up-jet.
It's all presently stock:
2014 PX 125
SI 20.20
Pilot: 45-140
140 (Air Corrector) / BE5 (Atom) / 96 (Main Jet)
Can anyone advise... oh, and in terms of the drilled air filter, is there a definitive answer as to whether the oval hole requires blanking, or not?
Thanks again, in advance.
