The Hole That Honda Forgot

Post by Solo So Long »



Okay, so the weak point in the design of GL1500 Tupperware is the need to either remove or rotate the storage boxes in order to remove the rear wheel.

Worse, you have to do this for a job which should be done every couple of thousand miles -- bleeding the brakes.

The actual process takes as little as a minute, once you have prepared. This also assumes that you either have a willing helper, or -- far better -- that you have installed Speed Bleeders.

It's getting TO the bleeder screw that is the royal pain in the okole.

That pain can be eliminated by putting in The Hole That Honda Forgot, cutting through the inside wall of the left saddlebox.

The dimensions that I am presenting work on MY 1989 GL1500, either on the center stand or raised off the ground on a jack. They SHOULD work for your GL1500, but I make no promises.

I used an oscillating multitool to cut through the case in the appropriate spot, which I determined by drilling a couple of time holes and looking up under the skirts. While cutting, I made sure to just barely go deep enough, and made small bites, looking through the hole with a light to verify that I was in the right spot.

A hole this size gives plenty of clearance for connecting wrench and hose. Be sure to deburr the edges of the cut.

This pic shows the ruler resting on the bottom of the saddlebox.


This shows the distance from the front end of the box.


A blank cover made for electrical wall boxes will keep all of the junk in the box in the box, and moisture out (there is stick-on weatherstripping on the back side of the cover).


Beautiful? No. Elegant? Not really.

But it gives easy enough access to the Speed Bleeder that there's no longer any reason to accept spongy brakes for "just one more week." I can put my catch bottle right next to the bleeder, eliminating about a foot of hose (and that much more lost DOT4 fluid).

Solo, you had me second guessing myself, but, I just checked and there is a 2.5 inch hole right in front of the brake caliber for bleeding the brakes. Having said that I have never used it. I always do a complete brake line flush when ever I change out the rear tire which is every two to three years, but the hole is indeed there on a 1999 goldwing gl1500 se

Glad they figured it out. The one I cut is larger and probably works better than what you have, but yours is certainly neater.

My 1900SE had a hole in the left bag for just such an operation.

So sounds like it took Honda 2 years to figure out they needed a hole there.

Just about.

Every once in a while, the designers at Honda must like to pretend they're at HD.

Interesting. Maybe they had a couple of different designs for the saddlebox? Or different subcontractors making them?

The only hole that was in mine was for a bolt (for the trailer hitch, maybe?), up near the front of the box.

I'm not sure which years had it, but mine definitely does.

The cover for it is that little piece of glued-on rubber, that never stays glued in place.

Cyclemax actually sells a replacement plug that press fits in there, and works much better:

Far out!

I think the bigger hole works better, but at least they gave you SOMETHING.

That looks like it's about the same size as the plug for the bolt hole I mentioned. I've opened that hole a bit also, and feed the cables for my electronics through it. I don't routinely get into the left-side box, so that's where electronics, tools, and stuff I don't usually need gets put. That leaves the top and right boxes available for things that I need a lot.
