Just how did you get a hold of an '84 400?

It is possible you are not in the United States, where other markets had bikes available that we don't.

In the US, 400s were only available in '77 and '78, which had B and C suffixes to the model names.
T and X were the suffixes for '80 and '81.
If, indeed, you do have an '84, the suffix should be E.

I thought the X had 8 valves and the T had 4,but apparently I am wrong Go here... http://www.thegsresources.com/garage...400rebuild.htm ...and here ...http://www.suzukicycles.org/GS-series/

Yes SR my bike is 84 GS 400EE black engine 8 valve I got it as a give from a friend I’m in Ontario Canada believe it or not I fix bike for leaving but every one I ask in this industry is as lost as I’m none have an straight answer for me as well as Suzuki dealer and I need to know what do I’ve to find a way to get part cause they’re every were but I just get so confused one thing doesn’t match with the other one when come to it. I need valve & piston. Is 84 GS400E same as GSX400E ????

The X just denotes bikes sold in countries other than the states. We got GS and the rest of the world got GSX. Same bikes with a different designation. You can get model info here. http://www.suzukicycles.org/All-Suzu...ki_models.html Don't trust the part numbers, they may show a different number and actaully be the same part. I wouldn't be surprised if the pistons and valves weren't the same as an '83 750 or '85 700. I have some extra valves for a 700 if you want to see if they're the same. Do you know what size valves they ran?

Hi Billy Rick’s
Yes is the same valve 84 gs400 to a gs750 invent the same part number I also found that is the same engine from 80 to 86 with a different from 80 81 and some small different through the rest of the year as well when they black coat the engine well I also go the manual on PDF but is more for 82 and other PDF for specific for 84 spec for now I’m at school my first year to get my motorcycle mechanic license .definaly if by the time I’m done you still have them we’ll see what can we do about those valves and I’ll be needing valve Gide too
