i raced my one at eastern creek(NSW) heaps, its a real blast
all i can recomend is exhaust, reeds, and a cr125 carby and pod filter, an tune it properly,and some rear sets wouldnt go astray as the stock ones hit the road easly
i use to carve up the bigger bikes every where except the straight
its really good when a new gsxr1000 goes past you at 260+ then you catch and pass him everylap
