Yamaha FZR1000 exup(1991) diaphragm change 

Thanks you are the best, looking forward to see your carb sync video,there are some carb sync videos out there, but non devoted especially to our beloved Yamaha fzr1000 , so looking forward to watching it .

The best way to check the diaphragms is to stretch them over a brite light

Those diaphragms, are they the cheap eBay ones that can be had for less than £10 the set? They’re listed as having an outside diameter of 69mm, but I’m sure I measured mine as 75mm diameter, I assume they still fit? Thanks 👍

R the emulsion tubes removable in these carbs?
