I have a ton of RE5 literature. Somewhere, I read that the cooling ports were a great effort by Suzuki to increase scavenging and increase hp. I just moved, and I have been challenged by someone on a forum, who doesn't know jack about the RE5 period, but has asked me to "cite" where I read this! Ugh! I told him to find it himself.
But it is bothering me. Can anyone help me with a citation!? Thanks.

Never mind. The web is full of cursory stuff re these ports. . I read this years ago in a specific article on the bike in a magazine I still have somewhere. I am done with forum I mentioned. Lots of clowns. No time for that. thanks.

Hi Speed, When you refer to these cooling ports, I believe that you are referring to the grills at the front of the exhausts? I wish I could support you as the rubbish people believe and spread about the RE5 annoys me too. However, there was some mis information from journalists back in the day. I have a magazine review where the guy thinks these grills had valves in them to control air flow. Not true.
As far as I can tell, those grills are for nothing more than cooling. The cooling air does end up mixing with the exhaust right at the rear of the pipe. I cannot see how it could possibly assist in exhaust scavenging. There are photographs of a sectioned exhaust on the forum which are worth a look. It is very likely that your memory is correct and you did read this. But I also think that the journo may have been misinformed, misunderstood a briefing or misread a flyer.
I bought a 4wd recently. Every local journo review said that it came with Limited Slip Diffs. Not so. It absolutely does not and no version of it over here is so equipped. But I think every journo got the same erroneous briefing sheet. I've read a journo test of the GL1800 Goldwing where the guy talked about the air assist rear suspension and thought the 25 units of adjustment were PSI. I have one of these bikes and a couple of suspension units lying around. No, they are not air assisted. That salt shaker applies in spades to a lot of things that Journo's say.

Scavenging?
Really?
Wow, some people have rather verdant imaginations.

One interesting fact regarding the air intake at the front of the pipe is that the air swirls through it the opposite direction down under. Extensive testing shows this makes North American bike just a bit faster as the air flows through as intended.

As we say down here in my neck of the woods... That Jeff feller... He ain't right... Best

Sorry Jeff but I just went and check the sink and the water dose turn differently to you guys up there , but becouse we are DOWN UNDER the air is heavier (more oxygen ) so ALL our bikes are faster than yours , and not to mention the riders are always better !!!!!!!!!!

I'll second that. We need to organise a drag race!!!!

Yeah, but all of your hot air counteracts all that.

Getting back to the original thread subject.......
Has anyone ever really looked at the air vent system. Yeah there are some openings in the front, but there's no exit point. If the air can't get out, it can't get in, therefore no air flow.
If it entered internally through the baffle some how there'd be now way to keep it from letting exhaust out through the vents. So I can only conclude that they're only cosmetic.

Yes they have. A perfectly good exhaust was sectioned wide open some time back.
It is called fresh air duct for a reason. Air is siphoned in at the baffle with a venturi effect

If you remove the removeable baffle at the rear end of the exhaust, then you can blow all the way through to the front air vents (I'm sure there's more than a couple of double entendres there!). The air comes in through the front vent, travels between the inner pipe and external chromed pipe until it tries to exit at the rear through the rear baffle(the bit with the glass packing around it). Sorry Tim, was that too literal?
