Each to his own, but today, as I parked in the supermarket underground parking lot, a Harley sportster was just setting off as I arrived. What an obnoxious sound in the enclosed parking lot. Glad I've got the quiet GZ. There again, us oldsters don't need that noise that the youngsters like. We don't feel the need to try & get everyone in the vicinity to look at our bikes. What gladdens my heart is that people have remarked how quiet my bike is. That's the way to get people to have a better opinion of riders. I bet if you ask your neighbours, they'll all tell you where to stick your loud exhaust.

Two things. Did you watch then put in the jet or did they just tell you that they did?
If you haven't gotten the bike up into the 3/4 - full throttle range, then you haven't even tested the main jet yet. It increases flow slightly in the other ranges of the throttle position, but it has the greatest effect at WOT. Think of it as the main jet being solely responsible for gas flow when you have 3/4 - WOT.

Why the bike is starting to run hotter and smell hotter could be one of two things. Either they washed the bike off a little bit or perhaps spilled something on the motor while they were working and it was just burning off, or you've been driving around too long on a bike that is now very lean and you're starting to notice.

Mods aren't supposed to be done to the intake or the exhaust unless jetting is already on the agenda. If this bike were fuel injected, it would be different. But it's not. You have to manually adjust the fuel flow or you're going to overheat some internal parts. Not trying to scare you, but people have melted their valves because they didn't think jetting was necessary.

Now that you have a new main jet in there, you need to test the bike and speed and see if it is pulling stronger at full throttle. If it is, and if you are satisfied with it, then you need to determine whether or not you need to raise the needle one notch. If you are smelling the hotness and getting some lag in the mid range 1/4-3/4 throttle, then I would suggest you do this. It's hard to have a bad experience by running slightly rich. But running slightly lean can be a big deal, as I have suggested. Better to be rich than lean and better to be safe than sorry.

You know what, don't even test it. Go ahead and raise your needle. There is a how-to with pictures. And do it before you post back here again.

Maybe your bike is too loud.
Down here, if they complain and you have modified your pipes you could be looking at a fine. It is supposed to be that way everywhere in the US since it is a federal law. Most police won't bother unless they get complaints which force their hand. Robert Frost wrote, "Good fences make good neighbors" but then again he didn't have a guy with a loud motorcycle living next door.

FWIW, it is illegal to change the exhaust on a motorcycle from stock in most localities. but that law is not usually enforced unless there are complaints about noise or obvious evidence found by an LEO on the scene hearing it.
