Digi Sync by Bon S

[BonS]

What piece exactly is the head unit? I plan on bringing mine to Inzane, but it would be smaller to just bring the one item you need rather than the whole devious.

Picture would be nice.

I also picked mine up finally from the mail house, looked through the items. I seemed to have gotten 5 short tubes with  the clamp and stoppers in them. Should there not have been 6?

Also, the battery and plug was nice. You also had what looked like a connector to a plug to draw power from the MC. All I would need to do is to wire in one of the many connectors I have for either my Battery Tender or heated jacket. Would this then not be running 12V into the Digi Sync? I'm sure you have accounted for the higher voltage, but I thought I would ask, since I don't recall reading anything about it.

Also I have a complaint too!

I'll now need to go out and buy a Valkyrie so I have a real test on how to use it. Or maybe I'll just meet up with icandoitfaster and sync his new IS.

Sorry about that, sometimes I get too close to something and use terminology that is familiar to me but not everyone else. this is the first generation head unit:



It sounds like you only received five of the vacuum plugs. I owe you one and will have them at InZane.

You're thinking right, you can simply connect your Digi Sync to your bikes 12 volt system. Your Digi Sync can handle up to 20 volts but I've never pushed it that far.

You've simply gotta' explain; You don't have a Valkyrie? I thought everyone owned at least two! (That's what I tell my wife.)

I finally got time to use mine. The PO said he had just synced the carburetors, and perhaps he did, the old way, as they were all within about 15. Now they are all within 1, and it feels just a bit smoother at low throttle, like pulling gently from 1000 rpm in 5th gear. Very nice. Trimming the pilot screws will have to wait, though; I just got a tool to adjust them (stainless tube crimped to a D shape), but they are too tight to turn with my fingertips; it will have to wait until I can take the carburetors off and free them.

[BonS]

That's great to hear WintrSol. I'm glad things went well. I got this knurled knob at Sears. It certainly gives you some torque on those screws.

[WintrSol]

That looks great, but the tool I found (on eBay) has a 1/2" block attached, and rests against the vacuum tube from the intake pipe, leaving no room for that. Got a link to the tool you have in the knurled knob?

[BonS]

This is it.

Thanks for the link. It says it is made from aluminum and stainless - is the body of the tool aluminum? If yes, strong enough to break a stuck screw loose?

[BonS]

It's made of "high grade aluminum and nickel plated" and designed to work with their geared D-tool driver that looks like it can generate some torque. Motion Pro makes great quality stuff. Will it break yours loose - I dunno. Just looking that tool and that they sell replacement gear teeth says how hard these screws can be to break loose.

I've seen some low quality D-tools made out of bent antenna rod or copper tubing. This one is certainly the best I've seen.

KY . Dave....I have one here in Northern Indiana (Logansport) Any time you are this way I'd be happy to sync yours with my newly updated Digi-Sync

[Gryphon]

Awesome! Now that you're synched you can send me just the head unit and I'll update it with the latest and greatest software for free. I even pay return postage. Or, bring it to InZane and I'll do it there.

BonS

I'll probably just mail it to you one of these days.  The bike has a tach so I coped without it and I'll have way too much stuff with me on the trip to SD.  Bringing the wife, so I'll be packed pretty tight.

[RONNIEB]

Bon,
Received my digisync almost a month ago.Been raining here pretty much allmonth.Got a pretty day and synced the carbs on my 99 Interstate. They started out within 5 of eachother now are within 1.
Also plugged off the vacumn ports on the middle cylinders as the lines were leaking. The thing will crawl out from under you now going into 2nd gear.
GREAT TOOL!!!
Thanks for creating this thing.

[Icelander]

Well, if you need a demo bike on the second day, I'll be bringing my first-gen digi-sync and an un-synched bike.

Kicking myself for not offering sooner.

An update.
 I am seeing a consistent 1-2 mpg more per tank, after using the Digi Sync. Only one carb was off a lot more than the others, but being able to bring all of them so close together and with such ease is a BIG OUTSTANDING!
Great Product

I was going down my list of saved web sites, came across the Valk riders and realized I had never signed up. I finally did and am now an official member. I've had my '99 standard for nearly ten years and have loved riding it. I recently added a sidecar as I want to be able to ride year round, living in the Catskill Mountains of New York. Anyway, I've been working on improving performance, came across this thread and got excited about the Digi S. So, as of this morning, I've ordered one, as i see no better option for keeping the engine synced along with all the other maintenance tasks. I have a specific reason for adding this to my growing number of tools. This past June I rode to Colorado with the goal of attending the USCA (sidecar association) national rally near Sturgis, SD. I never made it there due to an engine failure while camping outside of Idaho Springs, CO. I believe that something awful happened within the transmission of the starting gears as they were securely locked.

After hauling it back east, I parked the rig and hoped to find a replacement engine. I got lucky, found one through eBay, bought it and installed it. So far, I've ridden the rig to North Florida without incident. I want to keep it that way. Installing the replacement engine gave me some insight into the complexity of this wonderful machine. I had to work with the carburator tubes and air box as the fittings nevr go back like original. So, I had air leaks that caused performance degrade. I found one airbox tube not well seated and worked for what seemed hours to secure it. The performance immediately improved. Now, i want to make sure that the original carbs are properly synced. I look forward to receiving the unit as the video makes the project approachable for the amateur home shop.

[BonS]

Welcome to the forum! It sounds like your engine may have hydrolocked. In my opinion the best way to avoid this condition is to 1) Replace your carburetor float needles because they're old and tired, 2) Keep the OEM petcock in perfect working condition (or replace it with an aftermarket) and religiously turn it off when parked, and/or 3) Install a Dan-Marc electric solenoid to do this for you. I'm sure you'll enjoy using the Digi Sync as it'll ensure that you have a smooth, responsive idle, low and mid range throttle response along with the best gas mileage. Enjoy!

[hilf]

Thanks. I look forward to working with the Digi S.  I plan on tearing into the old engine to find out what happened to lock it up. I do know that the last time I started it the engine turned over, the starter ran and then there was a very loud metallic clank! Then....nothing. It was a long drive back to New York once I flew home, attached the trailer, drove back out, loaded and drove back home.

It sure sounds like a hydrolock....Starter ran.. .then CLANK....

[hilf]

As the temperatures plummet here in the mountains, I will look to my garage for inspiration in finding out what occurred inside that wonderful engine. Fortunately, I did find a replacement as I wrote earlier. Would a hydrolock completely lock up the starter gears while the transmission still changed gears? I have no experience this this condition.
I'm awaiting delivery of the Digi Sync. The postal service somehow diverted the package to another area so I may have to wait a while longer to receive it.Trying to get specifi information from USPS is as bad as contacting the Feds at IRS. There is nothing but recorded messages, no human interaction. Frustrating.

Yes it would not affect the shifting gears.

So I purchased by Digisync a few weeks ago and sync my carbs. The problem i ran into was carb six with the vacuum line going to the petcock. The instructions indicated to disconnect the vacuum line and suck on the line to open the diaphragm and then pinch it off to keep the diaphragm pulled back so that the fuel would continue to flow. Well I tried and tried I don't know how many times but once the carbs ran out of gas the engine would die. I could not get the diaphragm to stay open. Any tricks anyone has would be appreciated.     

Thanks,

Gerry 

[BonS]

Hi Gerry,

When you sucked on the petcock vacuum line did you feel that you achieved some sort of vacuum or did the air flow freely? If you didn't feel a vacuum then your petcock diaphragm is bad and needs to be replaced. Another alternative is to put the petcock hose back onto cylinder #6, with the engine running obviously, and let the engine do the sucking. Even with a bad petcock diaphragm you'll get enough vacuum to make the gas to flow enough to keep up with demand at low engine loads and RPM's. If using the engine to suck then let it do so for about 15 seconds to let the carb bowls fill and then replace the Digi Sync vacuum line back on cylinder #6.

[hilf]

Good news, the Digi Sync (#2) arrived in today's mail. That was fast. The first is possibly orbiting around the moon. Now on to reading and digesting instructions before implementation. I think I may have one slight air leak from cylinder #1 air tube. Those things just don't fit right after removing the airbox. I have a solution involving the use of silicone tape.

[indybobm]

i would forget about the silicone tape and make sure that the lip of the air tube for #1 is not folded under around the carb. Difficult to see but people use something like a dental mirror to check the backside of the airbox tube. Using the mirror, you can check to make sure that the rubber tube from the airbox fits evenly all around the top of the car. if it is folded under it will be obvious.

Hey Kep, I don't know where Plainfield,IN is from you, but I have never synced my carbs and was looking at the digitec, Let me know if you would want to assist me, maybe in the spring?  Thanks

Surprise, surprise, there was a Digi Sync for me under the tree this Christmas.  Actually it was no surprise at all, I ordered it weeks ago, received it and gave it to Susan to wrap up for me.  I enjoy surprising Susan with gifts, but I am impossible to buy for.  This process insures that I get what I want.
I'll have to wait for spring to try out the Digi Sync.

I hope everyone had a Merry Christmas...

[BobB]

I got around to syncing the carbs today with the new toy I got for Christmas, the Digi Sync.  What a pleasure to work with.  It took me some time but that's normal for the first outing.  I watched Bon do several Valks at Inzane last year.  My bike was already dialed in pretty well, only off three or four digits at the most, it was synced by Big BF last year.  I guess I'll have to find other work for Bill to do at Inzane this year.

Thanks Bon, great product...

That one's a little pricy for casual use; the link you provided before prompted Amazon to recommend a similar handle for $10, so I added it to the order. Once I get them broken loose, the handle will be 'handy'.

Hey WintrSol, if you shoot a bit of lubrication up into the cavities, I think you will find that the screws will break loose and turn easily, the problem is probably the o-ring binding and not the screw itself. THe O-rings are made from material that is fuel and oil resistant, so no worries about damaging anything.

Then you have to decide, which lube is compatible with the O-rings? I sure don't want to turn them to goo.

The O-rings are Buna-N.

[pancho]

Which is the chemical industry's current solution for a flexible/mold-able substance which is resistant to most commonly used fuels and lubricants available to the general public.  I think you would be hard pressed to find a spray able lubricant  that will damage it or "turn them into goo".
