I just purchased a teralow 4:1 np231 kit off one of my buddies for dirt cheap. Installed and but it keeps popping out of 4LO. Checked everything. Pads on both forks are in good condition. It seems that the range fork and mode fork bind in the range sector. I put it back in the stock front half and everything shifts smooth. Would a teraflex 2LO kit fix this problem. Appreciate any help.
