So I finally got off my butt and pulled the carb on my 2018 Brozz to rejet it.
I obviously ordered the wrong pilot jets for my carb. See pic
Can anyone send me link to the correct ones?

I ended up replacing the main. 105 to 115.
Shimmed the needle with one washer.
I dremeled out the air screw. Only thing I could find. It was set out three turns. Set it two turns out. See pic
I took the bike for a ride felt better off the line and mid range top end didn’t seem to improve felt more sluggish.
Bike will pull me from a stop at idle 4-5 miles an hour. If I hammer it from this speed it bogs completely like I killed the engine then it jerks forward .
Bike idles at 6 bars and will show a 7 th bars for a split second at a long light.
Started and idled better.

Thought about installing a 110 main with a 40 or so pilot jet .
It was 88 degrees here in Central Florida with 75% humidity.

Thanks in advance . My first attempt at rejetting a carb.
FYI engine is stock except for a iridium plug .

A 110 main and a 40 pilot jet with the needle in the 3rd or 4th notch (from the top) is almost the exact recipe for a low altitude mostly stock bike. A 115 is too big, even for sea level, without an exhaust mod/upgrade of some kind.

Step one: buy the Mikuni vm26 clone, sadly I've become way too familiar with this carb, but if you include your elevation I can tell you what jets and needle position you need.

*also include any mods you've done, the database on this carb is outstanding.

Quite a few of us here can do that with the Mikuni lol.

Bike is stock no modifications. I was considering removing the air box snorkel and install an exhaust. I’m in Central Florida, elevation 75’.
The pilot jets I purchased don’t fix. Any help here.
I found a Mikuni vm26 Clone on eBay for $35 bucks. Thinking about it.

Okay , I pulled the trigger on a new exhaust and a Mikuni Vm26 clone carb. Once I have the exhaust and snorkel out . Where should I start with carb settings ?
