hi guys, i recently got an rxs100, oh to feel young again lol... its standard apart from an allspeed exhaust. The exceleration is crap.....is it better to get a stock pipe fitted to make it run better or is there anything else i can do to improve eg raise the needle,k and n or? runs fine apart from exceletation......i would change the sprocket but dont want to lose top end speed of 65mph. cheers for any advice

does it only do 65, i had a 1983 rxs and that would do 70. try an iridium spark plug they like a good spark, you could try going up a jet size because of the expansion exhaust
