ive got a standard aerox 50 with just a leo vince zx exhaust what rollers would work best with this exhaust and where are the restrictors in this exhaust and the standard exhaust.
take the std weight and drop them by half the weight for double the revs and so on. it should rev at the same rpm all the way from 10mph to top speed
the zx is one big restrictor.. but they clog up with time and perform better. there is usually a washer/cone welded in the header (bit that bolts to the engine) remove this and make sure the weld is smooth and free of lumps. while your at it take a stencil from the cylinder and lay it over the pipe to match (usually the barrel is the smaller peice tho) the cans have a small diffuser pipe and are the wrong length for any kind of revvy setup. usually 5.5g rollers are fine (in piggys) down from 7g i belive. so thats around 78% decresae... so take your roller, weigh it and devide by 100 times by 78 an you will have the optimum roller weight. this isnt a perfect science tho so get a few weights and 3x3 it to get it just right.
