Thanks for the info Dave. Where did you get the stuff for Arrtu's setup? I am really hoping to figure out a way to use the factory VR pickups since they work currently and reliably. Like using the tach circuit to combine the two signals into one. Do you know if this has been done before? Maybe passing the signal to a factory module HEI or the Bosh unit that can run COP and be controlled by the Megasquirt ecu.

I am running fuel only at the moment using a dyna s for ignition.
I have the components and have made up an aluminium timing wheel that will hold magnets, this is Arrtu's design and it uses the same timing plate to give both sensor inputs by running one magnet reversed in the plate. Arrtu has run this setup in a few 4cly bikes and it works flawlessly. Have a look through the info below.
Nice too see others are doing KZ MS installs. I finally got sick of my 82 GPz1100 EFI that was about as smart as a atari 2600 that had a waffle jammed where the cartridge would go. I got the MS built, pretty much all the efi hardware (fuel pumps, pressure reg, and sensors) are there. I did end up modifying the stock TB set up to accept more modern injectors.
I used a set of GSXR600 injectors, flow rate should be pretty close. I had some "V" pieces cut via my neighbors shop's waterjet. drilled and tapped some holes, the machined my own bridge piece to connect the 2 since the gpz TB's were a bit wider. Just though I would share. Ill post when I get it up and running.
I got the plugs for the gsxr injectors from dynojet. I no longer run the stock pressure regulator since I only have a single fuel inlet, switched to a aeromotive bypass style.
Hey ratvespa, glad to see another megasquirted kz. That is some creative engineering you have going on there. What aeromotive regulator are you using? That is what I am trying to figure out right now. Some people are using ebay regulators:
Thats still the plan. I have almost all of the parts. Im still putting the bike togther and swaping parts. I'll update this thread as soon as I get the rest of the bike togther. I hope to have it complete by next summer.
You probably need an Serial Port to USB adapter so you can hook up to a Modern computer. Nothing much with a Serial Port on it anymore. The adapter I have cost like $8 on Feebay. Works good, there are also write-ups on how to make your own.

You better get on it... they are already in high demand!! Mine should be here the end of the week. I have a left over GM 3bar and a paxton FP reg from one of my previous projects, so I figured, what the hell right!!!
Im thinking of using a Z1000 or ZG14 TB's. Need to put my hands on a set to be sure. What do you think?
