just ordered a 07 attack gt.and was wondering if anybody new if the gearing is the same as the apex gt.and if i wanted to change the gearing for fuel economy would i add a tooth to the top or bottom gear.i hear these are not quite as good on fuel as the carbed rx-1.

dont bother with gearing,put wind on secondary clutch to 60 and put a little softer spring in front clutch,i put a 30-113(y-p-y),this dropped the engage rpm a little for smoother engagement and the total force was a little lower to which drops the rpm a little all the way thru shift,i got 15.5-20 mpg all winter depending on how i drove,this 4stroke likes the load of softer springs,still pulls 134 on speedo on hard groomed rr bed
