Throttle Issue 1979 cm400t

Hi everyone,

Back after a long hiatus. Finally got a stator to make this guy start but after taking apart the carbs and replacing pretty much everything I’m stuck at a throttle issue.
I put the bike back together but it seems the throttle won’t snap back. This is without the cables on. Im afraid I might’ve done something to the throttle when I was cleaning and replacing gaskets in the carbs? I’ve cleaned out the area around it with a parts dip and carb cleaner and still nothing.

Any help would be appreciated.

Your spring positioning may be off…something is definitely off if they are not snapping back. Might want to slowly work backwards and see where you could have gone wrong. Watch some carb assembly videos pertaining to your bike as well.
Hmmm that’s strange, is something catching on the butterfly inside the carb? May need to pull that shaft out to inspect it further.
Awesome! Glad you got it. Keep us posted on the bike!
