Main jet size change was created by KZ1100 Bully
In my Clymer book it shows that the main jet was 120R in the 81-82 model year and in 83 it went down a size to 117.5.
I was wondering why it downsized? All the other parts stayed the same.
I bought a kerker # 127-61001 I have stock Air box with K&N filter and I want to figure out what size main jet to use.

That is what I thought "EPA". So a bigger jet would help restore the some performance back before the "EPA"
Not sure what size jets to get Mikuni Large Round Main Jet
120 or 122.5 or 125 up from 117.5

I think I will start with 122.5 mains and see how they work. I don't think I need to make to drastic size change but I really don't know. Only way to learn is to try.
Thanks for the help so far guys.

I would have 20 idle jets while you are getting them. Roy
