I think I've read through nearly every different shovelhead clutch thread on here (and other sites) and I can't find an answer for the issue I am having with my bike. It's a ratchet top 4 speed with bearing support plate added and tin primary cover, foot clutch hand shift. New five finger clutch hub, BDL 1.5" belt drive, Ram Jett style retainer, Blue Barnett clutch springs. I have tried swapping friction plates and metal plates (all new and in good shape) and nothing changed. I've tried adjusting spring tension, clutch arm position, aluminum pressure plate, again no change. Everything is set up to spec, my primary belt if anything might be a bit loose (can move it up and down a good inch) which I think is better than too tight but the trans is currently all the way back on the plate.
The issue I am having feels like it should be clutch related. The first part is I'm getting a good amount of shudder taking off from stop in first gear, a problem that I've heard is fairly common but can be addressed with a tamer typically. Second, when riding and especially under load in 3rd and 4th gear, I get another shudder that feels to me like the clutch it slipping. Again, I have tried and tried again every clutch adjustment I could think of and I'm at a loss. Any info or ideas on what could be happening here would be appreciated.
