I understand what it does, but not how to tune it. I have a 650 SBA that can get "tail happy" through stutter bumps. The IGX is known for this. Would more or less rebound fix this? I do not currently have rebound adjust on my RTS. I did have them rebuilt with a heavier vis oil this year and I could not fell a noticeable difference. I would think this would have slowed down rebound.
