Here's a source for the sensors quoting a lower price. The catch is that there is a minimum quantity of 5 with increments of 1. If you are inclined to build for all 6 so you can sync a Valkyrie you save $4 each - $24 less than at Digikey. It pays to shop around. https://www.verical.com/pd/freescale-pressure-sensor-mpxv6115vc6u-253910 MPXV6115VC6U Freescale Semiconductor | MPXV6115VC6U-ND | DigiKey

I would say that it is likely #3 isn't firing at idle. There are several threads on that. Possibly a plugged pilot jet.

Great. The more the merrier. That's what the open source project on GitHub is for. The two big opportunities imho are the cost of the sensors and getting the RPM feature to work well. These sensors are about $15 each unless you buy a lot. You can order automotive MAP sensors for very cheap but what I haven't been able to find is the spec sheet. They are sold by car year and model. I need to know the range of the vacuum they can handle, and the accuracy. If any one on here is an expert jump in. There must be a way to benefit from the mass production of automotive MAP sensors on a project like this and still keep things small and neat. I've been able to use a non latching Hall sensor to read the RPM off a plug wire but it could use some electronic expertise to make that more reliable and stable. The signal source is the very definition of noisy. Size is mostly determined by the sensors and display solution. Cost is driven by the sensors. Everything else is pretty cheap and easy and as you say could be made a lot smaller.

Thanks. Your build looks good. I like the idea of tacking down the sensors with crude soldering of the non-functional side. I'll update the directions. Of course, using solder paste for the sensors is even easier. The pattern of the numbers lines up with the pattern of the sensors. On your build you have two rows of two, left to right, top to bottom. On Valkyrie builds one would have two rows of three.

In desperate need of a small carb part

Maybe this part# 4G0-14142-42-A0 4G0-14142-42-A0 YAMAHA JET,PILOT #42.5 or Yamaha 4G0 14142 42 A0 JET Pilot 42 5 1987 Warrior YFM350 1970 XS1 1973 TX650 | eBay or not. -

Oh wait. You said an 83. I don't know if they are the same. -

This? 12R-14105-00-00 YAMAHA PILOT SCREW SET -
I've been asked if I will build one. I don't really want to get into that kind of piece work. But if someone really wants to avoid soldering, I could do a couple of all-in-one with the board, the computer loaded with software and pre-tested. It would take a bit longer. PM me.

Even electric hardley's leak....

Thanks. It's designed to take that next step so the display can be eliminated. I've plugged it into a bluetooth enabled mcu and linked it to my phone. But I need to do a lot of programming to add function and style. The cost driver is the sensors. The 2-line display is only about $10 more or less.

I do have a few board and parts kits for members. Send me a PM.

My family tradition has long been my Dad's spaghetti and meatballs. The meatballs and sauce took 3 days to cook down to perfection. We used to able to find spaghetti noodles that were 3 feet long. A right of passage if you were dating a sibling or were a guest was to be able to roll the noodles into a ball with your fork. Cutters and slurpers were teased a lot. He's passed now but my younger brother now makes the meatballs and sauce every year. We had goose once but it caused a riot. Spaghetti every year.

While it is apart I would replace the hoses, by-pass valve and water pump.Starter, ground and fuse block. Ignatech TCI. Close inspection of all the wire harness connectors or replace. Test all the coils and replace as need be. Inspect and repair (re-solder) the dash display contraption. If you are going to progressive springs you can pull out the air ride, otherwise it will need attention.

Some factoids you can help me chew over. I posted info on this Venture forum and on a Valkyrie forum. Those are the two bikes I had in mind to benefit most during design although of course it would work on any multi carb engine (up to 6). There was generally favorable to enthusiastic response from those who posted. My survey attracted 22 responses. My Ebay no reserve auction of a board drew 3 watchers and no bidders. The parts kit did sell to someone who wanted to do a build and bought the kit for convenience. Discussions with a Chinese manufacturer resulted in a cost per assembled board of $150 for small volumes and $61 for quantities of 1000 or more. I could probably sell a kit for that to do it yourself types but that's about it. Now what? I'm thinking that I'll build one more for my brother. I have 2 for me. I have a few more boards and parts kits without sensors. I might hang on to them or make some available to open source collaborators on GitHub. I would swap a board and parts for a nice case if someone has that capability. And I am open to more suggestions. Stay tuned!

U-haul has charged me $15 a day for a motorcycle trailer round trip. All by myself no problem. If you use a plank to get it into your truck bed be sure to set up a video camera first. You'll want to share your education.

I was just wondering if you had noticed a difference of any kind. Did long time members show up less, or post less, or something. Did people stay on for longer or shorter sessions? That kind of thing.
-
Here's a picture of a small batch of the final board I just got. The main changes were to replace the voltage switch with a jumper, and evenly align the sensor pads so it looks better. I have one guy doing a build that will help me field test the instructions. I'm still not sure what happens after that - in small quantities it is kinda spendy. I'm having fun with it, though.
-
Yes, but... Yes, it works quite well now that the tweaks are in place. But, somehow it seems a bit less like a messy old garage full of guys having fun and a bit more like any other forum. I can't put my finger on it exactly, so maybe it's just that 'change' changes the flavor a bit. On the techy side, do web stats show a difference in use or participation?

And the internet was without form and void. And Al Gore said let there be light and information. And Al Gore separated the sources of light and information into commercial sources to be designated .com and (nonprofit) organizations to be designated .org and one ring to rule them all .gov And he saw that it was good and he rested. Now days absent the beneficial hand of the Al Gore Pandora's Box has been opened and there are now all manner of dot endings too many for even dot gov to understand And lo though many prophesize chaos It has not yet been written How the internet shall end.

It is posted on GitHub. See above. The board files, too.

FYI The software has been published on GitHub in repository Digital_Carb_Sync_Shield. The board files have not been published.

Response to a couple of comments from the survey: Yes - it does hook up and display all 6 carbs at once. There are 2 rows of 3 sensors and 2 rows of info on the display to match. All the drill holes line up so it will be easy to mount in a case. I have not designed or built a case. I am considering posting the software on an open source platform but have not committed to that yet. Thanks again for the suggestions and questions.
