Hello to everyone. I've just fitted a second hand sito exhaust on my 2008 Px 125.had a chrome exhaust on a long one went by the back wheel dont know name of it and I noticed a difference in acceleration and and will accelorate from 28miles an hour no bother in forth it seems a lot better the thing I've noticed is if you blip throttle while its stood it picks up then bogs down a bit then picks up again I'm on a 98 main jet should I go up a bit any advice please cheers alan.
