So I just buy a diaphragm and the slide for the worn one that I have.
I just want to know if the rubber need to stick in the groove because I can't hold it and put the cap on at the same time. Its better with the new one but I still have a little hole in the upper range when I go WOT I wonder if it's the accelerator pump.

Thanks boys

Wonder if I can mount the Naraku one from and make it run good. Motovista said that you can make it run with it but not perfectly.

Yes, the diaphragm needs to seat fully in the groove. Sometimes a light smear of grease can help hold it in place whole you put the top on.
