Adding some horses...

[Slick]

hey guys...

Im curious about if anyone has found ways to add some extra horsepower to a gl1000...Ive done a couple things, but Im just tryin to think of anything else... I have a smaller tire (16 inch) on the rear..I have opened up the air box and have a k&n filter so shell breathe better..I have pipes that help too...Any other ideas?

thanks!

early cams and electronic ignition

and hot coils ofcourse

This will do the trick......

Ahh...I forgot...its a 77 so she already has early cams...I've got dyna coils and ignition...and 1100 carbs too...

And Hal.....um..turbo much?? Is that yours or just found it out there? That's sweet...

[wingrider]

How much you want to add? All the time power, or just sometimes power? As Hal pointed out, a turbo will help, so will a supercharger, and a shot of Nitrous will do as well.

All things above will require a bit of engine work to sustain life.

If you just want to get up and go quicker, you can also look for gear sets for the rear end to give a higher ratio.

Doing this alone won't help. It actually may hurt performance. If you get the engine to breath better you also need to play with the carb jetting to get full use of it. Even then you'll probably never feel the difference. Maybe add 3 HP.

Horses aren't cheap. A GEM rear gearset can make a difference too (hard to find though).
I've got more money tied up in my extra horses and final drive than in the rest of the build. (Money well spent from where I'm sitting.) I have to believe that's true for anybody to get over 75 at the wheel.

You can go the route gregf took,or supercharge it as did randakk .But if you want to stay within Honda's realm there are not many things you can do like after market cams and pistons. And if you can find someone to grind you a more radical cam than what you have it wont do you any good unless you can find someone to match the cam with a set of pistons.. So you are pretty much limited to lower gear ratio rear end ,and carbs from a 75 .You already have the hottest cam,Dyna coils, and electronic ignition .

The biggest thing with HP is how much are you willing to spend. It is possible to take a stock engine and gain 10-15%. Maybe more. But it is very time consuming and labor intensive.

Custom grind cams can be found/made. That will work fine with stock pistons. If done correctly.

One of the big issues with the heads on an early GL are the heads. The ports are already too big. Hard to work them over and still have any velocity. And you don't want to turn the kind of RPM that the ports would benefit.

The easiest/cheapest HP gain is with nitrous. But there is more to it than just bolting on a kit and hitting the button. If you want the engine to live.

Like the old saying goes, and what I tell my race customers. "How fast do you want to go?" The next question is how many 100 bills do you have on you to start with?

One other thing. On the street torque is much more important the horse power. Especially on a bike/rider combo over 750-800lbs. So now you start all over.

But if you hang around the right gin mill someone might walk up and say " That your white wing out there? I got a sidecar gearset for that." And that's why it's better to be lucky than good.

I'd still like to see somebody get a good FI setup going. Webers are real good but a dedicated FI setup would be the ritz for naturally aspirated ponies.

[Slick]

Will I be able to tell anything with how my plugs are burning? They've always been a good tan..never too rich or lean..
As for the rear end gear set...would it be as simple as swapping a 1100 differential for the 1000?
I've also heard of big bore kits for the old GLs?

[robin1731]

Yes, plugs can tell you a lot. But they need to be checked at various rpm.
Try finding a big bore kit. Like the rear gear sets. They may have been made but finding them now is very difficult.

Like I said, how much do you want to spend? And how much do you expect to gain? Be realistic in answering those two guestions.

Itd cost about $700 for a pair but there is a company that makes throttle body replacements for the weber idfs, those coupled with randakk's manifolds $300 would probably be as close to "bolt on" as you can get. Of course then youd have to add in the related stuff to make them work (ecu, injectors, etc). Itd probably round out about $2k definitely not a budget build, but that circles back to how much you want to spend.

Im still looking into it but doubt itll work for my turbo build, would probably be great for someone staying NA.

always a good topic for conversation, but for the cost of doing a serious horse power gain you could buy a bike that is already faster. and even if you decided to build a wing engine with all the go fast stuff on it, the frame would be a weak link. and then you would have to deal with the brakes to pull you down from these fantastic speeds, and all this horsepower. so why not start out by installing an 1800 wing engine in the 1000 frame, with a busa front end and brakes, and a gem rearend set. 16" rear wheel modified to take a 200 tire, tuned exhaust, and a little nitrous. please post pictures as you progress
