Question about 1989 Suzuki GSX 550 EF
Fouled spark plugs...intake manifold leak... you could have a vacuum line come off or isnt on all the way. bad batch of gas..weak coils, or poor compression. or the choke could not be operating properly. also running too heavy an oil could cause this problem, you should run 10w40 only.
