Does it bog? Does it sputter? Did you go bigger on the jetting when you installed the bigger carb? How big is the carb? You also have a needle to play around with.
My guess though is that you need larger jets.

Delloroto 19mm i increased main jet size but it seemed like it did nothing no matter what size. Do you think i need a bigger pilot jet?

Open filter or the oem air box? What jets do you have now? Cylinder and pipe?
Once you let us know what you have then we can give you a better guess. We can't give you exact numbers, but we'll get you close.

I'm guessing somethings going on with the choke. It runs fine cold, but shitty warmed up? Choke circuit could be stuck open maybe.
Post some pics! I love these bikes. I've got one too!

Oh and i forgot that if i mess with the choke it hits the power band quicker. I guess you would call it bogging when i take off

Sounds like a leaking choke circuit. You still have the thumb lever for the choke on that one? I'm guessing sticky cable maybe.

I thought I shouldn't have to run anything bigger than around a 105 |
