Off the top of my head I know the nozzles are Q-4. I need to look at home for the rest of that info. You should be able to find what you need by doing a search on the board here. I have posted that info before.
Nozzles will be different for the 94,95's vs the 96's because the 96's came set up differently.
If you have a '94 or '95 you need to use Q8 nozzles, '96s already had them in there. The spec sheets say to use them in only the LH carb, my Yamaha dealer said that there was a later bulletin that called for them in both RH and LH carbs. So, for myself, I put the Q8s in both just to be on the safe side.
