A 1500 Wing maybe,but the Valkrye is a factory hopped up 1500.Different cams,exhaust and more carbs.The only thing that's going to make a 1200 run with it is maybe a twin turbo set-up. A single turbo might be close.

Here is what I know and it is not much:

The 1500 coil is better the Volkere may be even better?

There is a way to bypass the ignition circuit using a relay so you get a bit more juice to the coils.

And of course the shedding of weight.

I don't know about getting other injectors.

I wish many safe riding years to you and hopefully someone will know more than me.

The LORD is my light and my salvation--so why should I be afraid? The LORD is my fortress, protecting me from danger, so why should I tremble?

As I said, it just depends what you want to do. There are 1200 motored Gold Wings on the road today that will put the six cylinder Wings and Valk's in the dust... you just have to do the work to them in order for them to perform.

That's just not true. My Interstate showed well in contests of testosterone with 2 friends and their Valks.

Thanks for the support fellas, I really appreciate it!

I started looking for the coils online today, found some good deals!

Im not sure about mechanical aspiration on this bike. The KZ will get a supercharger or turbo as I haven't built a mech breather yet.

Ive got a buddy whos a big H-D guy and I think he's got a couple sets of sporty pipes sitting around.

this might be a dumb question, but are these CDI ignition bikes? I haven't torn into it enough yet to get intimate with the wiring

Thanks again guys!

1985 GL1200, all stock, left out in the weather for years, but 14,800 miles! came with all the factory goodies.

Well, in a photo maybe!

Seriously, a friend of mine who is a good Goldwing wrencher believes that porting and polishing and oversize valving the heads on his '86 GL1200 Interstate will make a big difference, combined with freer-flow pipes will make a big difference. I just asked him, "What will the engine displacement be after you do that?"

Before I'd spend the time and money to turn a GL1200 into a Valkerie hunter, I'd just buy a GL1500 (what I did) or buy a Valk. I've ridden my brother-in-law's Valk and it is a sporty ride.

Maybe so,but I'm betting that it took a lot more than coils,jetting and HD mufflers.It's going to take some good head work to make any of that other stuff work much good.

So what can one do to get more power out of GL1200? Which coils will work for a hotter burn? Ive looked at a set of Accel universal coils and someone mentioned Dyna coils?

Now mine is a Limited so is there a way of fitting a bigger set of injectors or tuning the "computer"?

Any off the shelf cams?

Id really like to run down my dad on his 1500 Valkyre lol

Thanks!
Why? He's likely running a bike that's no heavier (maybe even lighter), is 10 years or so newer, with 300 more CCs and 2 extra carbs. Be happy that he's having to buy more gas per mile than you ..... for a fact.

Also, a good tune and removal of excess weight along with using that 7500 rpm redline will close it up pretty good.

A GL1200 in standard form minus a few pounds ..... then things would be more "equal".

I wouldn't. Too much plastic on the 1500 for my taste, but that's just me.
