jerkiness

I had this problem last May just after Southerncross fitted a renegade airbox mod. According to them, it had nothing to do. The problem was solved after fitting a Dr Rossi chip, southerncross also fit a new Throttle body revision kit, part number AP0281241 and balance TB. 3 weeks ago this...

:confused. anyone help or point me in the right direction? got a 2000 mille and in low gears on part throttle, the ride can get a bit jerky. its fine and smooth once u get goin. I must look a right fool jerkin around at slow speed! any ideas? thanks, i'm new to the rsv world. lovin it tho.:thumbup
