your float valve isnt closing on at least one of your carbs

If you just got it back from your 1st service,,,i would just take it back to them,,,and say, "fix it"

 

did you remove the float and inspect the needle and seat??? was the clip attached to the float properly and without damage?

I got that alot from people

Took it back apart today and took the float off and checked the needle valve...didnt see any dirt or anything we just played with it alot and hooked it all back up and boom...it worked..lol...well time to put everything back together..if anyone is missing some screws ill prolly be able to send u some extra ones...lol

 

Is that drain screw sealing when you tighten it?

 

I usually just smack mine with a screw driver handle rather than take if all the way off the bike. It usually does the trick.

Next time If you want to test if the float is working blow into the gas inlet hose and lift the float up and down. You should notice a difference.
