550's - 8 or 16 valves?

I'm shopping for a 550 for my wife. I've read that the later models were a 16 valve motor. Any other significant changes to the motors? Will one last better than the other? Thanks.
 
From what I've heard both are super reliable. The 4-valve will give you more balls though.
 
The two valve engine uses a roller bearing crank the later engine the TSCC or twin swirl combustion chamber engine uses a plain bearing crank. The carbs are also different. I'll check on the years each was manufactured, post later. The 4 valve engine isn't that much quicker then the two :twisted: . Oh, the TSCC has an oil cooler too.

Much appreciated. I'm particularly interested in "standard" bikes. If it started to look like a sportbike (lower bars, rearset pegs), or if it's a "L" model, it doesn't hold as much interest for me. Not to offend anyone of course, but we all have our own ergonomic and styling preferences.
 
They started the 4 valve in 1980, and the TSCC in 83, I believe. The TSCC also had those messed up double carbs which I hear people complaining about, so I guess those are to be avoided.

The regular GS550 doesn't look sporty or anything, the GS550 Katana does. I'm not sure what the L means, except that the fuel tank is smaller (touring edition, riiiiight). Mine look like a plain bike from that era, nothing special. And that's how I like it :wink:
 
The gs 550's 83 and up look like sportbikes most have a half fairing in the front but the EFE has a full faring over the engine, the bars are low and your legs are somewhat tucked. The L models if i remember are the Katanas but someone else please correct me if i am wrong. I think you may be interested in the 82 and down models they have a nice classic look and i hear they are tougher than my EFE. the newer bikes are a four in line with a double cam while the older is i think a twin. there is a great description in the history homepage on this site.
