How do I find out my needle & seat size?

[Guest]

I had my Mikuni carbs for my 82 GS450 looked at it looks like its a bad needle and seat that is the source of my stuck float. A local Suzuki dealer wants $70 for one and if I have them put it in a minimum of $290 parts and labor. I'd rather do it my self and I found the N&S cheaper a few places online but how do I find out what size I need?

You see that very first thread marked STICKY..Factory carbs spec? I would start there.

Be sure and check with Z1 Enterprises also. You have to call them because they don't list everything on their web site.

You're talking about the float needle and seat, right? I didn't think they had "sizes" like jets do. The OEM part # is 13370-44010. Boulevard Suzuki sells them for about $40/set: the gasket and filter run about another $7. Wow, that's pretty expensive. Sets cost $30 each for the BS32SS carbs: of course there are 4 on those...

Parts 25, 27 and 28:

thanks for the help guys $40 still seems kind of high but I need to get this thing on the road. I guess it doesnt have sizes after all.
