So i took the R out to silverwood this past sunday and found out i wasnt'tas dialed in as i thought i was. I ended up having to lower the needle all the way down to get the right kind of powerband i wanted. However, i only get good solid response for the first 5 gears once i shift into sixth power just falls off and i actually start slowing down.It feels like its just not recieving enough gas. Is this correct or do i need bigger carb or jets or am i completely off.
