i have had, Vulcan 1500,1600 Classics, VTX 1800 ect. All vtwins. But I have rode a Venture before and I know this one is rpms are way higher than it should. Again the rpm match the speed and torque. Vmax drive is making more since now, just waiting to hear back from PO to see if this is the case. If it is, it has to go.
