      OEM style

      That is a different style diaphragm that has a built in retainer ring. DO NOT cut the OEM retainer ring like that if you dont have that style of replacement If you do, you will need a whole new diaphragm assembly part$$$

          diff.

          In this pic, you will note that the inside hole has a small thin ring. Do not cut the plastic retainer on this type


          In this pic you will see a thick retainer ring built into the diaphragm. Platic retainer must be removed on this type, making it so you can't us the OEM type again

              ive replaced my diaphrams with the top ones in the pic
              and have cut the top plastic retaining clip to fit them
              without any problems what so ever, theres a write up on
              here some where, if ur interested i can find it.


              btw $60 for 4 of them is really good value.

                Mfg

                Thats cool. I tend to go by the MFG's instructions when installing their stuff I know guys that do stuff their own way and get away with it. There is a guy on here that adjusts his valves by jamming zip ties between the valves and seats to hold them open, hay, if it works, its your bike, enjoy

                  Personally, I'd be reticent to cut anything off the OEM slide. When I replaced my diaphragms, I used the type with the thin ring. They go on easily if you use lighter fuel (liquid type) as a lubricant...

                    +1

                    +1 once you remove it, you cant put it back like it was, and the whole sliders are $$$. But, having seen what some PO's have done and still got them running, or at least enough to sell it to some poor smuck Like I say, it their bike, do as you will
