I am in the process of putting my Showa shock back together on my RM 125 and have a quick question. I cut the original factory teflon band and o-rings off the valve body and have the new one in hand. However, it is not split to allow it to slide onto the piston. The manual doesn't say jack about it other than cut off old and replace with new...I've searched and can't seem to find the answer I'm looking for. So should I be able to fit it on there without it being split, or do I need to cut it to get it on?
