Not easily, no.

There was one kit made by a company in Italy that purported to work on 1998 and newer GL1500s, for about $1000:

Of course, the engine case has to be split and the transmission disassembled to do it. I don't know if it would work on a 1995.

There was a distributor in the US for this kit, called LaMonster Inc. You can see an archive of their web site from 2007 here:

Their web site no longer exists, but they have a Facebook page. They appear to only offer Can-Am Spyder accessories and kits now:

Thanks that's a little more than can do. thought there might be something with final drive that I could change. @ 70mph I'm turning around 3200 rpm in 5th.

My 88 turns the same.I really don't mind,that's in a good power curve range.Red line is 5500 anyways.
I thought about putting on the taxi tire.I think its a bit taller and drops the rpm a bit,but I'm not positive if it will fit.

By going to the Austone tire you will see approximately a 300 rpm difference at 70mph. Additionally, you'll get a better ride, longer tire life and better handling, especially if you get caught in the rain. The tire fits fine although you may have to modify the flap in the wheelwell a little bit. It's not a big deal.
the opinions expressed here are just that-my opinion!

Does this also apply to the 88/89 wing?
I know there are some differences.

I have put them on 3 1500s now and all fit well after I moved the flap .they feel like the tire that should have been put on in the first place. with the cruse on at 75 I am running 3100rpm .leaving for south fl. sunday so ill see how they do . in a hard corner they don't handle bad just different.

A few years back someone else considered rear gear ratio changing, found it to be WAY too expensive.
Besides the case is pretty much dedicated to THAT set of gears.

The CT's are the simplest (and cheapest) way to change the ratio a little.
On item about the Austone, DO CHECK for screws protruding into the wheel well. I had 2 PO's and someone used a little longer screw and it touched the tire when the bike bottomed out.

:idea: My thought was Honda could very easily add a 2-speed drive shaft. There's enough room for a set of planetary gears. But strength is the issue due to the torque.

And don't flirt with dirt or darkened oil, all the faster your engine will spoil.
