At last it is good to hear the technical advantages of dual plug ignition and electronic ignition from someone who clearly knows a lot more than just how to adjust a clutch. Lovely stuff Mike, that was a treat to watch.

Love the idea of running a switch for changing the timing. I might look to incorporate that somwheres else. Brilliant. Honda vtec guys eat your heart out.

You remind me of when I was a kid trying to build bikes .my buddies dad would let me hang out and chop bikes. He built model a &t. Your show feels like he's still here. Thank you so much. 😁

Great explanation of electronic ign. Install. Thanks Mike.

We want to see you building that project bike! Thank you for all the videos and the information.

Great video Mike,....i truly enjoy any content you put out for us...thank you for what you do sir. I can't wait to see the project bike come to fruition!.....it would be a great honor to ride with you!

Hello Mike. Thank u for xplain the electronic ignition. Once again it sounds easy when u talk about it👍. Looking forward to see more on the project bike👍. "The Swede"

Good video quality and sound. Mike is very knowledgeable as a result of all his years on the Harley Davidson. His explanation concerning the hemispherical combustion chamber is very good and easy to understand why they put 2 spark plugs in each cylinder. Thank you Mike for sharing your knowledge to people like me who has not owned a Harley but can appreciate them thru you!

Hey Mike. Great Videos. Had a 79FLH with the original 79/80 electronic ignition. Ended up fitting a Crane hi4 single fire. Made a big difference to starting and general running. Love your videos, and enjoy watching those old sleds getting some old school care.

Nice explanation about position of the sparkplugs, never thought much about it, and dual fire actually makes sense. I entered the world of electronic ignition on my 80" Shovel -79 this summer and I agree that I'm not totally crazy about the VOES, but it seems to work fine so far. But it was huge job to make space for it under the FatBob-tank, very, very tight. Thank you for another inspiring video.

Thanks for the videos! I recently inherited my dads old shovelhead and with a lot of help from your videos, I’ve now got her running and ready for the road.

Love hanging out in your garage have a blessed week my friend.

Always great content !

Nice video Mike. I have a rebuilt 1979 80” Shovel and am running a VOES switch with a Ultima ignition. The Ultima is a Dyna module repackaged as a Ultima and cheaper. The bike is kick only with a Super E and 99% of the time starts on the first kick.Tatro Machine in San Diego rebuilt the motor and has software to program the module for kick only applications.He did his magic and as stated earlier, the bike starts 99% of the time on the first kick.The Shovel runs like a violated ape.Keep up the great work !

Jeez, I love this hands-on material, and getting my hands dirty. Thanks Mike for helping me to understand more about what I am trying to do. You are the greatest1

Had to watch this one again since you just posted a new video to show the custom programing feature. Good stuff.

Cheers Mike! I love the switch for the different curve. I have never seen that before. Great idea! All the best. Al

Hey Mike good video tonight... While I was out on the road this evening about 8 or so miles from home. It started to spit a little rain. Lightning and thundering. Then the rain got a little heavier. More sky lightning. And then it started pouring so hard I had to stop. Thankfully i wasn't that far away from a gas station with a canopy over the pumps to seal some refuge . Well by the time i got home the only thing dry was a little spot on the top of my head under my helmet. Man it poured hard.. oh well that's how it goes..See you out on the road..lol.

The ultima ignition is basically the same as Dyna just rebranded under a different name,really good ignition system

Im new to the shovelhead world.i got an 84' fxwg shovel with some s&s parts. 93 cubic inch. Im not a mechanic at all, that is untill i noticed i was spending more times on the side of my bike rather on top enjoying my bike. So thx to you pacific mike. I am a shovel rider and mechanic.lol well not mechanic but learning.

Love that bike of yours, its a work of art! thanks always enjoy your videos

That is a nice cool system you have. Learning all the time you have a video. Great stuff always. Thanks a bundle. Last time I heard dual plugs on a Shovel was 1977 and those guys were Bonneville bound. That bike was fast.

Great explanation of spark and ignition.....

Great videos! Lots of love from Alta Loma, CA.

Thanks for sharing! To quote Tom Petty..."The waiting is the hardest part" look forward to seeing the parts come in for the project bike. Stay healthy!!

Another educational video!! I love the ol' Shovelheads... Always have, ever since my first one (76' fxe in 2004, 79' flh custom in 2006 and a 79' fxe in 2014.. that was also my first street bike wreck). Listening to you talk about This shovelhead is overwhelmingly exciting! I know that sounds weird and kind of goofy but, I just really loved both my shovelheads. I say both as in two, because the 79 FLH Was a basket case,, I had to sell it after my motorcycle wreck to pay for medical bills. . . Anyways... I really really appreciate your knowledge and the content of your videos. 🇺🇸😎👍

Another very informative video Mike . Be Safe!

This is like a bike university! Thank you so much for doing this!

Great stuff brother Mike. Ride hard ride safe be well

Hello my friend I am a fan of duel plug heads I used to have a Thruxton Bonneville with a four plug head as the triumph head is one piece so good for you my friend the more efficient and quicker the burn the better so take care my friend love duel plug heads regards Alan.

Another great video Mike! It makes me want to buy an older bike to play on!

I'm feeling your pain. I've got parts at various places for my build (a 1935 Studebaker Commander coupe) that I can't wait to get back so I can continue on. And I'm NOT getting any younger.

Thanks again for all the groovy information.

Great video Mike

Thanks Mike, I still have my plastic plug run it up to 2000 rpm and have my buddy move the points plate while I held the timing light. If I was in the hills a lot I would put the mark just a tad towards the front, good times 😎

Good evening Mr Pacific, quite a tough topic to squeeze in 15 minutes but to the point. Technology has done wonderful things for our scooters. Take care of yourself Mike

THANK YOU...for sharing. Fantastic contents. I got educated. Appreciate your videos.

Too cool!! Thanks for sharing your knowledge!!

Great job

Very cool vid mate love ya bike i just pick up a restore 1979 flh on friday night cant wait to start tinkering 😃

Interesting show. I'm running points and condenser on a 78 shovel. Nothing even close to your ignition but it works for me. I carry a extra condenser and points in the saddle bag. You probably already know this, but in the event someone doesn't. The points for a 1960's General Motors 6 cylinder 235 cubic inch engine work well in a Harley. You do have to do a little modification using a file on the points bracket. If you purchase new points and compare to the points you took out you will see what I mean. Thank you for another great video. Keep the rubber side down and have a great 4th.

Great video 👍🏻

I had to stop cleaning my car, in order to watch my favorite man!

Outstanding information.

I've been waiting for this one.

As usual, well done 👍🏽. My mechanic called and said my baby isn’t getting fuel ⛽️. Can’t wait for the project bike 🏍 and I can’t believe 2 people gave you a thumbs down 👎🏽, now that really blows my mind.

I didn’t know you could do new tech on the old Shovel! Super cool 😎

Great Video!! I'm running the original Dyna S system with the mechanical advance. Love it!!!!

wow thats cool, i worked on a drag car pit crew years ago did not even have that at the time love it Harley tuner bikes

Hi Mike , You have entertained me [ and many many others ] , so , if you have the Time , a little True Tale . I also Twin Plugged my Harley in the late'80's , fast forward to about '94ish , Standing outside my Local H.D. Dealers , and a New Harely Rider was looking over my Motorcycle , and of course noticed the Twin Plug Heads . He asked me why , and I explained that Harely had to conform more and more to noise and emmisions Reg's , and , Hondas Flagship , Expensive NR750 with oval Pistons had not really caught on , and Honda had been left with shelves full of Oval Pistons , H.D. had done a deal , and I was on the Experimental Motorcycle , with Honda oval Pistons and needed two Spark Plugs . Funnier if you had been there , with my Buddies listening , and trying to keep staright faces . Hope I have not bored you too tears .

Guy, girls listen to this guy. OG HD. BIKER . 👍👌. MAN THATS A VETRAN 👌😎

I have run a Dyna single fire dual plug set up on a 90 inch shovel stroker with a five speed and a 22/40 tooth final drive. The bike would get almost 50 mpg on the highway with a Super B. I think I was just barely off the idle circuit at 80 mph. A single fire set up just has a very distinct sound to it but that was 30 years ago though.

Hey Mike I like your stuff man

Did this to my shovel 5 years ago. Have had zero ignition issues since.

Great information, but no more 100 mph wrecks !

Thanks Mike

Thank you Sir.

Thanks for another good one Mike. How about an Alternator / Generator charging system test ,? Stay safe.

Hi Mike 👋 good video ,again 👌 i have old ingnition ,with old Beetle’ s Parts on it

Wow Mike that’s the most tech on an old bike I’ve seen...cool

Hey Mike thanks so much for another great video... I always enjoy tuning in.. So listen I've got a question for you & I apologize if this topic has possibly bin covered in an earlier video. I'm guessing that I've watched about 75% of your content & scanned thru but I may have I may missed it.. It's about your heads & exhaust on this beauty Shovelhead.. You get a good look at about 5:34 in the video. I really like the way your set up with the four bolts instead of a single one.. Is this something you machined up yourself of is available for purchase to public kind of thing? Maybe Exhaust options with there pro's & con's of design etc could be a topic suggestion for a video in the future... Anyway if you have a minute to reply would be much appreciated.. Take care of yourself Mike.. Cheers from Dave in Canada..

👍👍👍👍right on A lot of good detail In the video.

Your awesome man.

Just had a Vulcan unit fail...I happened to have the points set up that came with the bike...fired right up. Going to run that for awhile till I remember why I switched them out in the first place lol

Top stuff as usual , I've read and watched loads of content about setting 1340 evo ignition timing , any chance of knowing your take or methods of setting up on these motors dynamic or static methods ? Lovin the videos 🙏.

Two of my friend with shovelheads that switched to electronic ignition had a fit kick starting them after they did. One bike is stoked one wasn't. both are 1977's have you seen that yourself. I still have points in my 72 FLH and it starts very easy with the kicker.

Hi Mike great video! I like how you hooked up the VOES to a toggle switch. Could I do this with my Panhead also?

Thanks for the video Mike. It cleared up a couple of things for me. One question I have (maybe a dumb one at that), how and what bracket did you use to mount both coils?

Thank you

Hey Mike, love the videos. Learning a lot. Had a question for you that the rest of the commenters could help answer. I just picked up a 72 Shovelhead, Its got a super E carb and looks to be completely stock other than that. Id love to make it into a true roadworthy bike, not afraid of long road trips. Do you have any advice on upgrades or maintenance that I should begin on to Improve reliability/rideability?

great idea thinking about upgrading my 1995 Harley Davidson Electra glide classic I have a Crane FireBall HI - 4E Motorcycle Ignition module and I have the VOES switch and I'm running a CV Carburetor on the bike she is running great but I have had the ignition module for a number of years. and it is probably due for an upgrade after seeing your video I'm thinking about doing the same thing. any advice or changes you could recommend would be much appreciated thank you for all of your videos always look forward to watching with my wife and our dog as well.

Hey there Mike, I’m wondering what your opinion is on the Crane Fireball HI-4E external programable ignition modules? I recently had my duel plug S&S Shovelhead stroker motor rebuilt and the guy who did the rebuild for me was pretty adamant on my replacing this ignition with one of the Twin Tech ignitions for inside the cone. What do you think is best for me to be running for optimum performance? Thank you for time.

I have a shovel 73 like yours s&s duel spark plugs, I bought a duel coil bracket. I have a Dyna DS-6 duel fire ignition... Q) looking at Dyna DC-2 1.5 ohms x2 are these the correct coils? I assume short jump wires coil to coil? What spark plug wire do you recommend on this engine and plug wire routing information plz. Thanks for the channel ur my go to guy.

Good stuff Mike. If you don't mind, where did you pick up your extensive knowledge on all things Harley?

Nice ... Thanks

Mike, I like to revisit your videos to get more insight. I am late to the party again. I did an upper rebuild on my 83 shovel. I had points but converted to electronics. The bikes runs good. Good fuel mileage. 175 degrees with an added oil cooler. I kept the engine stock. I have a super e carb on it. My question. When I check the plugs after a ride, they're darken and not that tan color. Not oily. Probably running rich. No dark smoke out of the exhaust. I tried the lean mixture adjustment on the carb, but it's not improving the look on the plugs. Someone mentioned that it's ok to run it a little rich so the engine runs cooler. Thoughts?? thanks.

Great video Mike! Thanks! Question I’m using the same basic setup... Dave Mackie dual plug heads, 9:5.1 pistons, dyna 2000i Ignition. Problem is the long plugs are resistor plugs (autolite 4265), where the short reach plugs are not (autolite 4275). Any advice or recommendations on correct plugs to use? Thanks again, and enjoy the channel!

Mike: What is that negative battery terminal bar you use on your shovel to make hook up easier? Is it an off the shelf item or something you just made? Where do I get one? Thanks for all the great content.

Pretty high tech stuff tonight! 🤓

I am rideing an 83 so it is titled shovel it is a built bike aftermarket frame delcron cases I have no idea what is in side but runs as good as my old twin crap but with a lot more fun right now it is running on points and I kinda like it that way I have had an electronic on an evo go out and I was stuck but points I can work on I have had to do it on a 74 fxe I use to ride but to the point if I changed to an electronic with a single plug would it make much difference in the way it runs I think the insides are basically stock and when the bike was built the builder used some very nice parts I think he built it to ride

Hi Mike. Love the videos. I notice that there are no fender rails on the rear fender. What model is that off ? Thanks.

Great Topic , as I am just about to pull heads for weeping head gaskets and ignition up grade. On 81 shovel . ( currently points) If you were you , would you dual plug heads? Cheers! Just shoot me a thumb up or down . I bought bike new, Love It

Very interesting video Mike. Even though English is not my mother language easy to understand. Is there any information which advance curve (Ultima 53-644) is best for a 1988-883 Sportster? Would love to see a video about choosing advance curves. Sincere thanks.

Hello again & another great video. I actually am running the same ignition on my shovel. Dual plug heads & the two coils in one deal. Is there an advantage to running separate coils? That's the direction I'm leaning on for my chopper build. As always be well.

Putting in a Dyna S on my 72' XLCH and I'm at the "static timing" portion. Instructions does call for the front cylinder to be on its compression stroke. I put my "line" at the center of the inspection hole. Not the "dots". When watching your video you mentioned that the line was the rear cylinder. I was about to change it, but checked my old HD service manual titled: "Sportsters 1970 to 1978", first. There's a figure 5-19 showing the line in the middle. The description reads: Advance timing mark on flywheel for front cylinder piston 1971 and later. 40 degree BTC. Can you help me understand? I've owned this bike since 1984 and it was always a 2 kick start ......until I had the motor rebuilt. Now it's not reliable. With a kick start, that's not too good for this 62 year old vet. Hoping that going electronic is the way back to her former glory.

Hi Mike. About the custom toggle switch. Does the switch just connect the VOES wire to ground, to get the advance curve you want?

My brand I use in my 98 Fatboy except mine is under the seat and replaces the ignition module has a basic hole switch in the cone

Hey Mike, I note you time the ignition on the TDC mark. I run points and time the ignition using the advance mark, which is what most people I know recommend. Are we getting it wrong?

Cool!

First! Keep up the good work, Mike!

Mike! Very nice bike, I also have an 83 Shovelhead FLH. My question for you is what forward controls are you running. I currently have the stock floor boards on my bike and would like something more comfortable for my height.

Mike.....I had as least two pop up add for medicare supplements. (are they trying to tell Shovel head viewers something?) The older I get the more I'm into reliability. I've ran points,electronic,and Morris mags on Shovels. (kick start,SU carb) Fact is, points always started the best of the three. (it's been said that if it isn't a good starter it ain't worth a "F")We know timing is everything and the factory FX cam also seemed to outperform even Sifton cams (starting)for me. I've ran Dyna (I like them) but a guy had better carry spare parts. Nothing wrong with points and a well cared for mechanical advance.....I like to play also!...thanks for the vid!....walt...tulsa,ok

Zipper ignition is what i use.kept breaking the dyna in my stroker

I have a question that's been stumping mechanics around here. I inherited a 92 dyna from my brother. When I got it front cylinder not firing. Replaced ignition timing module by the cam and the coil and plugs. After that now the front one fires but the rear one not firing now. I'm lost lol. Love your videos you are a wealth of knowledge. Thank you

Does the dual plug + electric ignition improve fuel efficiency at all? As in, do you get a cleaner, more accurate burn which requires less fuel?

Mike I hate to bother u My spyke ignition module went bad I purchased a new module this one has 5 wires? Old spyke had 4 So any advice would be greatly appreciated what wires go wear new module red,white,green,blue,purple white and red to hot? Blue front cylinder? Green rear cylinder? Purple ignition? Scratching head ! Thank u like your videos I to am rehabilitating from my crash back in April

Mike I just.brought a 74 FLH, it is not.running, it has an oil.cooler mounted with a front spin on oiler filter What weight engine oil should I use and what brand, also for the transmission. Thank you Sir.

Do you still have your primary oiler hooked up? I saw the pipe in place in this film. Maybe a good subject for a video?

Sounds like me trying to type lol, love it peace.

Hello Mike, I am tuning my freshly rebuilt 1975 shovelhead. The engine is stock but has a Dyna electronic ignition. My question is do I need to adjust the spark plug gaps based on now running an electronic ignition versus the previous points system. For some reason I am thinking that the spark is hotter now that I have an electronic ignition so therefore my question regarding the spark plug gap. Thanks in advance.
