I have a Sherman Breakdown a.k.a. Breakout Plus with SPV. When I pull up and unweight the front wheel the fork the sag in the fork seems feel like the bottom is dropping down instead of gliding down. I called Manitou and they said it is a low oil level. I checked the oil level and even added alittle more, it didn't help. I just replaced the rebound dampner. so I know that it is not that. I have also messed with more and less rebound. I also have added and lowered the spv pressure. If anyone has any ideas it would be appreciated.
