Jet question

[85Max]

I was cleaning my carbs last night because I checked the float level while they were on my bike and they were off bad on the 2 cylinders I've been having problems with. Any way, while cleaning the jet block I was looking at the main jet and it had been taken out many times before and looked a little beat up so I thought, hey I bought a set of carbs from a 95 max on ebay, let me use that jet.

Well the those carbs came to me totally disassembled (been great for parts) The only jets in the bag are very different from the ones in my 85 max (I have attached a pic) In fact the ones in the bag say "170" on them just like PAJ2, but all the PAJ2's are installed on the parts carbs, so are these main jets? Are these stage 7 Jets? Are mine the stock jets?

In the pic my jets are on the right and have "152.5" stamped on them. The ones from the parts carbs are on the left and have "170" stamped on them.

Bottom line question is which ones should I use?

The 152.5 should be the stock main jet. The jet on the left is Dynojet 170...most likely from a Stage 1 kit. The jet on the right is a stock Mikuni 152.5.

Thanks Mark. Which one would you use?

Are you running stock exhaust? Are the carbs totally stock? Stock air box? If yes to all of this then put in the 152.5's.

Carbs appear to be stock, Air box is stock. Has SuperTrapp slip-ons. I'll stick with the 152.5's thanks for the advice.
