all the time.When do you use one?
red is 3.125, turquoise is 3.0625, something else is 3.00. most all of mine are bare aluminum, because i make my own, and there is too much spread between the colored ones.How do you know which color? and...
to fine tune the boat??why?
So how would you know if:all the time.

to fine tune the boat??
-generally-, stock cast nozzles are too large in diameter for the application, and they are not perfectly round. inserts are round. some people use a .125 and never change, others use different sizes as part of tuning.
When i went from a 3.125 to a 3.090 i sure noticed a difference in my holeshot. So, to say you can't feel it by the seat of your pants is an understatment. Im going to play with them again here this weekend and see what the difference is on the mph. I think with the .090 i lost some,but gained in the hole shot. It's one of those things, which would you prefer I guess.It's one of those deals where you may pick up a mph or 2, or a tenth(or whatever) if you're racing. I doubt it will be a seat of the pants difference. I wag going to mess with some but my nozzle isn't machined for an insert. Some nozzles come insert ready, but my old split bowl isn't one of them. I believe the theory behind it is that the smaller nozzle opening will build more pressure. Hope this helps...
