Hi, I participated in a drag meeting recently on my standard gl1500 and got it down to the low 14 seconds. I came away wanting to do more. I believe if I were to remove everything off the bike and add sticky tyre, some straight pipes, clip on bars and a wheelie rail it could shave a few seconds off.
Has anyone out there done these mods ( and more) to a 1500 or 1800?
Im open to any advice.

The GL1500, and especially the GL1800, have monster amounts of torque. Stripped of weight, both would definitely require a wheelie bar in order to be able to put down all that power without flipping over.

If you can get your hands on a Valkyrie 1500 standard model, rejet the carbs with the special kit available and change the exhaust, you'll have a bike that will walk away from anything.

A friend of mine, years ago , had a Valk Interstate, he redid the exhaust with a 4" truck stack in place of the muffler. He welded in a 3" washer with a 1" hole about 6"-8" in from the collector to give it back pressure, and had it rejetted on a dynometer, that bike was a ROCKET that none of our club could catch !
Reputation is what other people know about you. Honor is what you know about yourself. Our stress about it happens when the two aren't the same. Be true to yourself and to hell with what everyone else thinks!

I'm thinking nitrous oxide is probably the quickest method to make your bike run faster. Or... buy a fast motorcycle if you want to drag race LOL...
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

No doubt everyone passed him while he was at the gas station though. :)

Use you favorite search engine. You will find Goldwings and Valkyries with Nitrous oxide, turbochargers and superchargers. While we all know how durable the boxer six cylinder is, once you pump some boost on, the weaknesses will start to show up.

You will also find there is not much room in the swing arm. If you want a good tire for the strip, you will need a modification to get more room.
