The rubber plug is there to plug off the chamber they had to cast in the carb so they could install the low jet. As you can see the low jet draws it's fuel through the main jet in the circuit next to it. The jet delivers fuel to the idle and off idle circuit during the transition up through the rpm's where the secondary jet take over. That's the jet on the right of the low jet.

It's funny you ask about changing the low jet. I'm getting ready to do some testing and development on the low jet when it comes to running non stock exhaust and filters. It will be a couple weeks until I can finish what I think will make a difference on the way these bikes can run when modified. But yes, I think the low jet should be bigger when the system is modified. I'll be doing a post about it when it's all done.
