gl12000 into a 1000 frame 76 carbs

[ericheath]

If you don’t plug them you will have an open hole from the exhaust port of the head to near the carbs, a potential boom-boom. I’ll take some pics if I can.

Kinda off topic... what is the reason you are wanting to put a 1200 in a 1000 frame other than the obvious? Why not build the 1200 to your liking? Seems like a popular swap

I have a 1000 frame available, no 1200 frame.

Ok, I get that. I didn't know if you had gotten the engine or whole bike for $400. I was just curious if maybe the 1000 frame was better than the 1200 frame for some reason. I'm building my 75 1000 now and plan on working on the 1200 next

It’s a pretty big opening. I think a back fire in the exhaust could come back through there.

If you crawl underneath yours or tip it up, with a flashlight you’ll see it.

I am running 76 carbs, so would I need to do anything to those holes (really)?

Part of the “afterburner” for the turbinator so the flux capacitor doesn’t get too hot.

There are o-ringed tubes which fit there.
To use it you need the 1200 carbs and intakes. Guys who disable it plug the hole with JB and whatever. I bought four freeze plugs close to size and used JB to seal. The hole leads down to a port in the exhaust. Each hole goes up to a collector under the base of the plenum. I never looked into what it actually does. Probably adds air to pass emissions testing??? Another option is using the tubes/hoses and plugging the plenum end.

You will definitely need to plug the holes but it will run fine without the tubes. I have removed them from a Valkyrie and a 1200.

Ok, I'll look for some plugs and jb weld them in.

For those that have used the black box, where did you mount it?

Got the shaft in place, so about ready to get the engine in, and black box wired up.

Now I realize that reason the shaft needs to be swapped out. There is no groove on the 1200 for the snap ring.

Being that you have completely done a 1000, it might be worth it to look at the starter chain cogs, if nothing else than to clean sand relube.

Others have tried the 1000 shaft on the 1200 output shaft and it did come off. You’re close, but far from riding season.

You have to plug them if you don't use the 1200 intake manifolds. If not there will be a massive exhaust leak. That is part of the emissions system.

I fabricated brackets to mount 1200 coils where the originals were, and a bracket to mount the ignition box to them. Be aware, it was a lot of screwing around. I wanted to use the 1200 airbox, and it's really, really tight.

[ericheath]

If I recall correctly the air box almost hits the heat shield on the lower right side. I carved out the center section of the shield leaving the two braces. It makes for easier installation.

I haven’t figured out a way for my V65 carbs to be enriched when decelerating. So I have a little farting going on when I slow down. For me, it’s appropriate.

That looks pretty amazing. I looked at the space i have with the dyna coils, and i just don't think I'll be able to make that work.

I'm leaning towards the right side shelter, and bolting it in place. I would like to find a location closer to the coils and carbs,but there's little space.

How did you connect the vacuum house to the carbs? That would be my next dilemma,as the hose would have to be longer than i would like if it's in the shelter.

Other option would be above the airbox, but then i would lose my tool tray.

I removed my heat shield.

You should consider putting a neon coil in there. The towers are off the side and wouldn't interfere with your airbox. Also kicks out a pretty good spark for cheap. Lot's of threads on that - here's mine where I put it in an '83.

Just a thought, I wonder if the impulse from the coils might interfere or even damage the control box. When I installed the M box wiring system they cautioned to mount the control box at least a foot away from the coils.

I was thinking the same thing when I saw that.
