Long story short bike got stolen but got my racing carb and 36 tooth sprocket back. I got a new kit put it on another 26 inch cruiser but it's super slow I did everything the same as I did on my old bike I used to be able to do 35 cruising and top out at about 40+ now maybe 25? It runs good for the first 5-10 seconds of a cold start but then rpms drop and it kinda boggs at full throttle I've removed the baffle like on my old bike like I said everything the same but running kinda bad.. Maybe running a little rich? I put a little more oil just for the break in but cmon. Also it doesn't sound like it's firing every rotation at higher rpm I tried my friends spark plug and his runs good and made almost no difference. I'm running out of ideas I've tried almost everything I can think of.
