Hi all
I Have a 2013 PX150E and recently had a blocked carb so, so while i was cleaning it out i noted the jet sizes when i compered them to a manual they don't seem correct and look more like the jetting for a PX125, someone said it was due to emissions for the UK, so could anyone shine some light on the subject.
I have altered the main jet as i have fitted a Sip 2 exhaust these are what are fitted now

Main 98 was 96
slow 45
Mixer BE 5
Starter 60

This is what my manual says should be fitted

Main 100 which should be 102 for the sip exhaust
Slow 48
Mixer BE 3
Starter 60

If i was to change them would the engine need to completely re-setup and possibly on a dyno ?
