What are the advantages and disadvantages of dual plugging a set of shovelheads should I dual plug Evo or twin cam heads what are the difference in the combustion Chambers!
I dual plugged my 78 FXS back in 91. I ran wisco 10:1 pistons, Andrews B grind, S&S Super E, single fire points ignition and it was kick start only. Bike ran great and started easily cold and hot.
Do you change the plug heat range? How much do you change the timing? I did this to my 76 FXE no other changes Ran a 128.8 at El Mirage total street bike
Gary you are awesome to start with. I want to send my heads for my 01 fat boy to you and gave them reworked. I need address or website or something please. Second I have 06 Electra glide also. Let’s say we do the heads. Once that’s done I was wanting the s&s 98” big bore kit. I ride like a bat out of hell. I like to go fast. At the same time though the wife does not. What would good cam options be to have both reliability, torque for Me, and be able to load darn thing up with momma full bags everything.
great video! Machinist friend at work helped me dual P the heads on my 73 shovel running an S&S E-carb, Andrews A cam, KB pistons and 1.75" drag pipes. how should I determine shorter advance degree? Trial & error?,
Do you still offer this dual plug service? I have a Shovelhead that I’ve wanted to dual plug for a long time. And if so, do you recommend doing it to big twin evo heads?
Sorry I have not replied sooner I am relocating my shop from Illinois to North Carolina. I am very close to having the shop backup and running if you'd like to get on the list please Email your Contact information to bikersphd@gmail.com Thanks Gary
Hi Gary. I’ve got an 83 FXR I had cycle shack 2 into 2 and never had a problem with the exhaust bolt. I installed an RB Racing 2 into 1.... which I love....and the rear bolt just fell out for the third time. I did the first two and actually had a shop do the last install hoping it’d go better. Do you think I need an insert or that repair you were speaking of? Odd that it only happened with the new exhaust. Thanks
Hey Gary, I was wondering if you are still doing this? I want to put dual plugs in my Shovel If you are I guess I need to call? I live in Oklahoma I really enjoyed your video.
We are currently closed we will be move in the new place most of April if you want leave me a text message on the 309-694-9002 # and as soon as I can I will get back to you thanks Gary
I really appreciate you reaching out to me currently I'm in the process of getting my shop reset up I moved from Illinois to North Carolina I should be pretty close to being able to do them If you'd like to send me your contact information bikersphd@gmail.com and I can Contact you as soon as I'm up and running thanks Gary.
Gary. Love your vids! Question: Is it worth it to do this on my '99 carburated (re-jetted) TC88 motor with true dules & stage.one? Sounds like the combustion chamber on the TC engines is fairly efficient already. Thank you in advance!

Great video Gary. Very well explained. Thanks.
Seems like a good place
I had to subscribe : ) very informative video ... that would probably dramatically improve the cold start behavior of my shovel , I guess ...
Gary. Need some videos. You have 4500 subscribers. Need your knowledge passed out to us. God bless.
Why didn't HD do this from the factory? Seems so much better in every way.
As always great video Gary

InstaBlaster...
Any time you hear "stage 1" or "stage 3", laugh or run. It's an arbitrary video game term.
What exhaust pipes are on the red & white bike you were showing the dual plugs setup?
Thunder header
Hi, will twin spark Infiniti in give performance on Twin Cam engine?
I my opinion no it's not needed.
I am very interested in having duel plugs on my Shovelhead. I sent you a PM on Facebook.
I cant find them no link no nothing
What link are you looking for?
@@Vtwinheaddoctor Power arc dual plug coil. I looked at their site and can't find them. I also noticed you said they were a prototype.
