Mikuni rebuild kit springs?
Does anyone know what two springs are in the SBT/WSM rebuilt kits? I can't find them listed anywhere, and the OEM kits have 65g and 115g springs. I've already bought the WSM kits

Not sure what gram springs they are, but you should just go by the pop off pressure. One of the springs should get you to factory spec not sure which ski it is but generally around 12-20 psi is the setting for most Polaris models. Get yourself a pop off tester it's a must when doing a carb rebuild.

Hey, I work just down the road from you in Milford! All of the WSM kits I've bought come with only 2 different springs.
This is actually for a SeaDoo 782, but the Polaris guys seem to be more technical than some of the other groups on here, so I thought I would ask in this section. I put Prok filters on all 3 of my engines, and now I need to lower the pop-off pressure. I was told by a local expert to start with the 65g spring, which is fine if I knew what came in this kit.

Wish I could help ya. Funny you say that. I notice that I hardly ever get any response when I post in the other sections. The Polaris guys are on the ball. Thanks Guys!
Edit: oh yeah, you could always try each set. you got a 50/50 shot at picking the right ones.

If I remember correctly the spring lengths were slightly different. I would start with the one that's closest to the stock spring
