The point is that it was a VACUUM LEAK that went undetected for a significant period of time that caused the meltdown, not the presence of a VOES. You could experience (and are more likely to, in my experience) similar failures from a bad intake seal. To suggest that the VOES itself was responsible for the failure isn't supported by your accounting of the situation.
My 30 yr experienced mechanic SAID, " Engine melt dn due to extended neglect of bad or leaking VOES". What else can I say? He is a big fan of not using the VOES. He installed My Dyna S ignition and I could not be happier, No VOES on my system to leak or other failures.

Good idea, I was just suggesting There may be a vacuume leak or Voes problem and other things developed beyond my control.

You're happy with what you've got - GREAT! For street ridden machines in which part-throttle efficiency is important, VOES is a big help. Eliminating the VOES because you're concerned about a vacuum leak is really nonsensical.

The extended neglect of a vacuum leak is the issue - that the rubber line going to the VOES caused that leak is incidental.

Thanks for agreeing with me. Im sure the Leak made a very lean situation to cause the engine melting. To me one or multiple less equation's to break down is a pluss. The VOES has vacuume and electrical that can cause problems so where is nonsensical come to play?? So if your happy with what you have GREAT. Your welcome to your opinion and Ill stick with my superior Dyna ignition that gives much better preformance without the added vac & elec problems. Any subject on this forum as atleast 10 nay sayers so this is par for the coarse. Now on to what oil to use or windshield or fingerless gloves.
As to the OPer, I would stay with stock untill all the bugs are worked out.

• These systems use magnetic rotors with OEM-style mechanical advance spark mechanisms to retain factory advance curves and illiminate VOES vacuume problems.

The rubber line going to the VOES is part of the VOES, it needs it to function.....

I sincerely apologize for suggesting that the system that HD and other engine manufacturers designed to improve upon the 40 yr old tech that you're running and has been proven to work over many millions of road miles could in any way be an improvement.
Simple is good. Pullin' off stuff that works just to pull it off? Not so much.

I agree, but if you want better performance, as I allways do, That philosphy just does not work for me. The OPer said he was putting in a EV27 and that allways works better with a preformance igniter, hence Dyna S, eliminating 40 yr old VOES technology. I hope this explains my whole point of view because Im not trying to argue with folks that know a lot more than I. Im not a HD mechanic but Im not allways wrong either.
I just finished building my 97 WG and had it built the way I wanted it built. It's a strong running engine and the OPer also has an 97 and Im just trying to be helpfull.
Picture of finished for now 97 WG.

My guess is that the mechanic blaming the VOES is probably either the builder or tuner of said engine or at least had a hand in it and is trying to put the blame where it shouldn't be. As far as the VOES being 40 year old technology, heck the V-Twin technology is much older than that!!!!! Almost all modern street engine ignitions systems have some form of vacuum/ air flow sensing being used to eliminate detonation.
