jet kit??

[mossyoakboy]

so while I was cleanin my carbs I noticed on my main jet that it has the number 105 and on the starter jet it says 525 I believe.... is this stock or is it aftermarket and if it is does anybody know what stage it is???

[kilika2]

There is a small decimal in there. 52.5.

[mossyoakboy]

o ok.... so you know what that means?? cause im new to bikes this is my first one and I do not know the differences with the stages of jets and how to tell what is what

I believe 105 is the stock main jet size for the CA models.

If it doesn't have the exup valve then its not a ca model right?? cause mine does not have it

Not neccessarily. The PO may have replaced the stock exhaust. Or... Maybe they bought a different set of carbs that happened to be from an EXUP bike.

Just checked - The CA & 48-State bikes ALL had the 107.5 main jet from the factory. It was the starter jet that was smaller on the CA model (50). Since your starter jets are 52.5, they are likely 48-state carbs. Another possibility is that your bike came from a higher altitude (think Denver, CO, etc.) and was therefore jetted with smaller main jets.
