With open carbs and a straight exhaust like that, you're going to naturally smell more of the combustion process... It shouldn't be overpowering but it won't be as toned down as a factory set up would be.
That is another option, by the way, should you want to go that route. You can put the stock parts back together, reset the carb to the factory setting and go from there. But I'll tell ya the exhaust is expensive unless you find someone who wants to part with theirs.
Do you have bike buddies who could give it a ride and see what they think? I don't know how much of what you are experiencing is an issue or if it's a result of overthinking due to lack of experience, and I don't say that negatively. Sometimes it's just better to have a second set of eyeballs...noses...whatever
