It will have an eefect, and you will ntice the effect. It is not quite as dramatic as the 250, but still very strong... with the bigger motor, you have the option to run a slightly different map and get more power everywhere, rather than the common 250 option of "is this thing ever going to stop revving so I can get the front wheel down?'

Good luck
