We show you how the S&S Easy Start Cams for 1999-later Harley-Davidson® big twins work, and how they save wear and tear on your battery and starter...and you won't be the guy who's bike won't start! Find out more -- www.sscycle.com
I'm getting ready to do my 2010 FXDWG. Thanks for the positive reinforcement! BTW what kind of tuner do you use? I have an FP3 and thinking I may have to abort it in lieu of Dynojet PC. I wish I had watered that money tree! Lol.
Great vid very easy to understand.On my 3rd set of cams and the S&S 585 Es cams are great.Also run the S&S big bore kit great power and a great roll on in any gear.
chris bioski Yep normal shut down sound.All I could recommend is making sure you run with a high over 585 head springs.All the best with your mods.Pietro.
Great video as always. I have a question about balance. Doesn't this device throw the balance of the cam off? Even if you counterbalanced, I would assume the cam is balanced with the weight protruding at high rpm versus in the low rpm position? Obviously you've somehow addressed this, but I am curious.
Balance probably doesn't matter much, within reason, for a camshaft. The lobes are already going to keep it unbalanced, add to that valves spring pressure through the lifter onto the cam is going to add probably more side load to it than the centrifugal force would.
Excellent question! We were concerned about this during the development of the EZ Start cams, but it turned out not to be a problem. First of all, the roller is still supported because the open space is not the full width of the roller. It doesn't just fall into a hole, or have to skip over one. Keep in mind also that the EZ start trigger, and the open space it leaves when it's retracted, are on the heal of the cam. There is virtually no pressure on the roller at that point because the valve is fully closed. We introduced the EZ Start cams in 2009 and here is is 2014. In 5 years we have not had a single warranty issue with this. We sell a LOT of cams, so in addition to our testing that we talked about in the video, there are many thousands of cams out there that have run untold numbers of miles. Hope this puts your mind at ease!
Would this also help for a kick start and key turn ignition? I have a 96ci Evolution Big Twin style 84-99 Compression Ratio of 10.1:1 with S&S 585 Cam, S&S Super E Carburetor with Super stock ignition.
+Victor Cardona Sorry dude! Easy Start cams are not available for Evolution style engines. With four lobes on the single camshaft, there just isn't room for the Easy Start mechanism.
This is very impressive, and someone else asked a question about what I was also concerned about, and you answered it, the roller not being fully supported, across it's surface, is not an issue, but there is still something, that saddens me. You mentioned this technology, is not available for Sportster models, so this would include Buell models as well, mainly the XB family. I have yet to disassemble a Buell Blast engine, or seen a video of a full disassembly, but, I doubt this technology is available for a Blast. Is it because the camshafts are too small in diameter, for those engines, and no metal is strong enough for that moving part, and the camshaft itself, at that size? Or it's just not possible, because there is no room for a counterweight? I guess, now, I have to research if a starter motor upgrade, exists for Buell blasts, a starter motor, that is stronger, and more efficient, because I am increasing the displacement, from 492cc, to 600cc, and I never thought about how hard that would be, on the stock starter motor. I also hope, if an upgrade exists, it's American made, because I want to support my country. Well, you have a great invention. I will also look at your site, for anything I could use, for my Blast. I thank you and your company for innovating.
Ohh. I took a good look at the Sportser cam, you had in your left hand. I was thinking maybe the mechanism can be shortened, like a shorter seesaw, positioned into the cam gear, like a cave, and the counterweight made bigger, by wrapping around the cam shaft a little, like a crescent, but can see, there is simply not enough room.....but great news, I found a starter motor for Buell Blasts, stronger then stock, more efficient, and made in the U.S., CompuFire Gen III Starter Motor - 53883 Thank you for replying.
If you have a stock or mildly modified engine the standard cams will work, however it's not a bad thing to release some of the added pressure on the started with the Easy Start options.
I have never hold any of these in my hand. Maybe that should answer my question: What in the mechanism keeps the trigger in it's sleeping position? Is it spring loaded, or is there a secret in geometry? If you solved that by a geometric trick, well, then i am really curius. I hope it is possible to understand what i am trying to say.
I have a SNS 103 motor it starts very hard I do not have compression relieves on it if I would order this easy start cam you're telling me that it would help out a lot?
jake lennon Assuming your bike is 1999-later model, you will be totally amazed! These things really work. If you have a shovel or Evolution® engine S&S does not offer Easy Start cams for those engines.
Yes I have an evolution motor so thank you for getting back to me I will keep looking on what to buy for it tell pat start easier if I send my heads to you guys can you put compression release in
jake lennon You said you have an S&S engine. Some S&S cylinder heads are machined to accept our electric or mechanical compression releases, but many are not. If you call our tech line at 608-627-8324 they can help you figure out if yours are. If your heads are not machined for S&S Compression releases, you should be able to make your engine start easier with a cam with more duration. Our tech guys can help you with that too!
@@SSCycleInc I have a 2016 Street Bob with a 103” stage 1 motor now. I’ve ordered some S&S 551 easy Start cams. Do you think I picked the right cams? I haven’t gotten them yet.
Help! I have a 1989 Harley Davidson Softail Custom - it has starting issues because of a few high-performance add-ons. In the video the mechanic said that the easy start cam would not work for my engine. Do you have any other suggestions?
John Schossow Excellent question! Another viewer asked about that almost a year ago, and the answer bears repeating! We were concerned about this during the development of the EZ Start cams, but it turned out not to be a problem. First of all, the roller is still supported because the open space is not the full width of the roller. It doesn't just fall into a hole, or have to skip over one.

I know this post is old but can anyone tell me how the 585 east start cams worked on a 96 no head work? Should I buy some or go smaller? Eventually want a big bore but that’ll be at least a year or maybe even 2 years.
Can a easy start cam fail somehow? I just put your S&S 110 big bore kit on my 103. I currently have the 551GE cams. Having issues, my Harley will start,but not fire on the rear. I was told a few months ago by someone at S&S on the phone the 551 would be ok., or get the MR103 585. By your video this may be my problem correct? Didn't want to order IF not my problem, but IF I can get someone to say this is my issue with my 110 Big Bore kit
@@SSCycleInc Chris said I needed to go with 585's instead of the 551GE, I was only firing off front cylinder, now will not start at all with my S&S 110 big bore kit:-(
My 2013 FLHX is at 50k miles and I plan to install S&S 551cams, new tappets, bearings and tensioners next winter. Do I need the EZ start cams? Doesn't the H-D 103 already have ACR?
You don't absolutely need the Easy Start cams, but they will save a lot of wear and tare on you starter. Yes, you have ACR which is adequate for a stock cam. The 551 cams are pretty short duration resulting in higher cylinder pressure, which is why they make such good torque. We still recommend the Easy Start cams. You will have to calibrate your EFI system with a cam install, and most Flash tuners allow you to shut off the ACR electronically if it causes any problems.
I just think if S&S stands by its motors they'd NOT sale you these so called easy cams. If not its S&S new way to stick it to you and get more money outa you
