So i recently bought a PX 125 from 2011
It seems to be a real bad breather, is replacing the original airfilter a must ?
but specially the exhaust system on mine seems really bad.
I remarked it completely overheated and i think it is not fitting well on the engine.
Will it help if i just replace the exhaust by the SIp road 2.0 ? ( http://www.sip-scootershop.com/en/products/racing+exhaust+road+20+for_24165500 ) is this the one i need ?
Do i have to buy gaskets aswell ? do i have to change something in the carb ? is there a manual to be found somewhere, my german is not fluent enough to completely uinderstand the tutorial videos...
