Front lockable pocket temp

hmm...
Methinks yacht-vents gonna look odd...

I'd rather throw pop-tarts in and just munch along the ride... ;)
 
I've decided to try the following. I'm going to put one of these vents in the front of the pocket and one in the rear. The rear should vent fine since there's an opening in the fairing there. The front, well I'm going to try it first just in the pocket without altering the inner cowl. If there's not enough flow then I'll modify that too. I chose these vents because it looks like rain would have a hard time getting in, as well as bugs.

The ST1100 has something that would probably work.
It's a scoop and plastic hose that runs back to the air cleaner from the front fairing.

Thanks for this! Looks like a good way to get the air back to the vents without having to do a hack job on the inner fairing.

On the ST1100, the 'scoop' screws onto the inside of the fairing so the mounting holes are already there.
The plastic hose is easy enough to cut and is very flexible.
There might even be some on EBay floating around.

Something like this would be easy to design & 3D print for the pockets. Several years ago, I printed something similar for the intake and exhaust of my new HE furnace to keep critters out.

I considered that but I don't have a 3D printer. But, this will be a good "prototype" test to see if I'm on the right track. I should be able to do some testing this weekend and will update with the progress.

I took a quick peek at mine... a square vent may be better for increased airflow & putting it at the top should keep it safe from water ingress.
I'll take some measurements and start fiddling with some drawings & await your results.

You will end up with dust and dew accumulating...
How I know?
I've made (small) cable entry bores in the pockets of my ST1100 and I'll have to wrap the items in frezer-bags (PMR, noise filter) and clean the pockets out...
 
Leave the lids cracked open to ventilate with passing ambient air.
 
Well there's already a hole in it at the bottom from the factory for drainage. I planned to put the vent in the lower 3rd of the front since it seems like that's the most exposed behind the inner fairing, then the rear vent put a little higher to hopefully get a flow that will pull the air up and out.
 
Phase 1 testing complete. Without the vents I'm getting 135 degrees in the pocket. With the vents in the pocket, but without any extra vents in the inner fairing, I'm getting 122 degrees now.

The air temp today while riding was 90 degrees and it was 94 before, so that may make some difference.

Not a huge difference but it seems it's heading in the right direction, which is good because I was partly worried about the vents just letting in more hot air from around it.

Now I'll add a vent to the inner fairing and see what that does. I figure it shouldn't affect handling as Honda put one in on the other side for the horn.

Well, I’ve learned some things, and hopefully this will help anyone else who may want to try a similar project. I figured that since the pocket is more in line with the backside of the headlight I needed a way to get the air up to the pocket. Using Uncle Phil’s scoop idea, I attached a “scoop” of my own since I couldn’t find any of the ST1100 ones around for sale. My scoop was in the form of a shop vac head. I was able to drill a hole for and use one of the ubiquitous “push pins” for one attachment spot. I wanted to use them all around but couldn’t get enough purchase on the two spots up front, as you can see in the photos. I then cut out a slot for airflow. It all fit together just fine and looked as close to stock as I could get it.

So…the results…a mixed bag

I took it for a ride and while up to speed put my hand in the pocket to check for airflow. The scoop did its job and I could feel a pretty good amount of air coming in through the front vent. Great so far. Then as soon as I parked it I stuck the thermometer in there as before. When the temp stopped climbing it was at 119 degrees. Still much higher than I hoped.

So I’ve come to the conclusion that while moving it works fine and probably keeps it pretty cool in there. But as soon as it’s parked it’s all moot. The air and components surrounding the pocket just start to bake it as soon as there’s no air flow around it, raising the temp. This is a dealbreaker for me as my main goal was to be able to keep certain things in there while on a trip and be able to go and have lunch etc and leave those things in there without them being fried.

So, it was an interesting experiment but I’ll be returning things back to stock. Personally, I hate hack jobs, and although I’m ok with doing certain upgrades to my bike, so long as they’re done tastefully and don’t ruin the look of the bike, I prefer to keep things like fairing and bodywork stock. To me there’s a certain beauty in keeping what the designers came up with. So, with a new pocket and inner fairing on order I’m all in about $90 total for everything, I’m ok with that loss. It was worth it to try. And I’ll still have the modded parts in case I want to try something again in the future.
