I need help w/clutching a 1992 v-max 4 that has psi quad pipes, that fancy cdi box that was made for them---can't remember the brand, and hauck head mod. I think hauck did some port work to the cylinders as well, to change timing. This is my friends sled so I don't remember everything exactly. I do know that he said it pulls well of the line to 7500 and then it just stays there. He had a heel clicker clutch kit in it and has changed clutching already a million times and it still won't go over 7500 rpm. Does anyone know how to clutch a sled with these mods? Does anyone have a good ballpark setup to try? Any help would be greatly appreciated. We would like this sled to work well this year.
