The best way to check for proper clutcing is on the hill, not a track stand. Draw a couple lines on you clutch sheaves from the center to the outer edge, take a run or two up the hill and take a look at the wear marks on the sheaves. Primary should be within a 1/4" of the outside and secondary should be about the same off center. The secondary reacts to track load and running it on a stand does not give you a true picture. Once you see where you are topping off at, you should call slp and tell them what it is doing and ask them for their recommendation. It is their clutch kit so they would be the most logical choice to ask about changes. What kind of track speed are you thinking you should get? If it never ever bogs dow, it is not being loaded enough. They should backshift but that engine is made to be loaded and not just spinnig free.
