Update;
Ordered 4 new diaphragms from Sirius Ind. on Wednesday, they came on Friday. Now that is service!!
Pulled the old ones out, one at a time, left 2 were in really good shape, soft and pliable, no holes that I could see with a strong light. While I was in there I used the keeper washer to space the needle up and put a different washer on top. Raised the needles app .028". That is about half the distance between slots on my Vulcan needle, and one slot to the next makes a big difference in the fuel mileage on it.
Right side the diaphragms were some what less pliable, one had several tiny holes, about the size of a 20ga needle, the other on had 2 even smaller holes. We were expecting company so i didn't get to ride, but it does sound smoother coming off idle and revving to about 3k.
We'll see today.
