    just built my fourth bike. brand new engiine. i used break in fuel mix, and was gentle with her for 10 days. took her out for her first real ride yesterday. rode over 60 miles and she ran beautifully. flawlessly. i got up the next day and she ran fine for a minute or two, then couldnt make any power. all she does is bog bogg bogggg. if i open the choke a tiny bit she will limp around. i simly dont understand the difference in performance with out me changing anything. i need help from a carb expert.

    I would say check your head that's it torque down correctly , as for as that CNS carb all I can say is good Lucy. I run a sha clone (RT) , I'm not the guy to help with that carb. Theirs some members here that can help you . Good luck.

    Check the fuel flow to carb,with a full tank..Your filter may be restricting flow.

    New build? What mix ratio are you running?

    I'd be checking the fuel line as suggested above and pull the bowl.
