Good day and welcome to Just Answer. My name is XXXXX XXX I'd be happy to help you with your problem today.
Is the air box installed while you are tuning?
Where is the you mixture screw set now?
everything is back on the bike made sure the airbox boots were seated on the carbs and snug the I'm not sue were my mixture screws are on the carb
ok, that is a problem as your carb can not be serviced/cleaned properly without removing the mixture screw.
I'll get you a diagram, sit tight
here is a link to your carb exploded view, #5 pilot screw is your mixture screw.
that screw controls very important carb passages & with that screw installed, you can not properly clean out the carb body.
they are typically capped from the factory & those caps typically need removed in order to access the screws.
That diagram illustrates them with thumb screws though so, yours might be very easy to access.
those carbs actually need quite a bit of disassembly to clean properly.
ok let me go look on my bike real quick and see if I can spot them
accelerator pump, starter plunger, tps cleaned & reset.
They are most certainly there. You do not have different carbs on your bike that those, & all carbs since forever have had mixture screws of some sort.
if they are capped from the factory as most are, you will only see a shiny aluminum cap.
They are considered emission related components & it is technically a federal offense for you to mess with them, & the manufacturers are required to cap them.
yeah I just checked to see if I could see em and they have a cap on em. Thanks for your help
unfortunately, your carbs need removed, disassembled & completely serviced again.
Thank you. Be sure to note their setting before removing as that will be you start up setting when firing it back up.
