I had similar problems with an '86 GS550ES I bought that had been
sitting for several years.
The carbs were pretty crudded up. Lots of sediment in the bowls and
passages. Also, the slides were not sliding up and down nicely. This
is quite likely the cause of the stumble then take off problem. I
lapped the slides back into their bores which helped the beast run
much better. It still doesn't idle well when cold however.
