[HD Street Performance]

My goodness would anybody pay to have the motor pulled, cases bored and the convert from a 103 to a cvo 110 configuration?  You buy trouble.

My thoughts exactly. My cousin has a 2015 Ultra Low with the 103. He's talking about putting in the HD 110 kit. I'm trying to talk him out of it, instead going with mild head work, and some nice S&S Cams and lifters. I told him his numbers would be equal to, or greater than a stock 110, and a whole Hell of a lot more dependable.

Here is one way to go. Not a recommendation because it is not that great for 2700 dollars but not terrible either.

And it comes with beehive valve spring...

The first thing I would change and have done several, 205# seat pressure.

A set I checked last month, MoCo 103" stage 4 @ 1.840" installed height = 190 # on the seat. SE beehives.

Still too hefty for the 7mm 7° locks. I am sure you have seen them start to distort the grooves and the valves need to be dressed just to get them out of the guides.

I don't particularly care for beehive springs. That being, the 1 big problem I find is if a spring breaks, usually the sh*t hits the fan. With dual springs, if a spring breaks, the inner spring will generally prevent the valve from having a mind of its own.
But yes, too much spring pressure will cause many problems.

From what I see about the 110 motors,...Is that if you hold onto it long enough eventually by the replacement and the upgrades of parts with the most commonly used S&S parts you'll have a good look a like Harley Davidson S&S motor that will run better run quieter and last longer. Something to look forward to.

No problem with the two 110's I've had. I'd buy another tomorrow if it was something I wanted.

same here had 10 and 12 cvo streetglide only mods were full exhaust and tune no problems hope the 17 Milwaukee 114 has the same luck got mine in april so far so good

2012 cvo skunk installed gmr 577 adjustable pushrods & S&S premium lifters in 2013 . On route to Sturgis with 98K. Will have over 100K when I get home.....if it makes it

I think so, if you like to pile on the mileage.  The dealer rebuilt my 110 at 96 000 km. Now at 144 000 km a lifter totally went. Contaminated the whole motor with metal and is getting a new long block. I am glad that the warranty will take care of this but it will take 2 to 3 months. And now I am without a bike during the summer. Thank god for extended warranty. I could never afford the repairs if I had to pay out of pocket.

I was wondering,...does the same thing happen to Non-CVO bikes that install the "110 Kit"? In other words, if a regular 2016 103' engine was upgraded, using the HD 110 kit, would it start self destructing too? Would the lifters chew up the cams, the crank start pushing the limits of run out and so on?

I don't know about all but a good friend did that and he now rides an Indian after all the things you mentioned.

That answered my question Terry. My cousin Alan was considering a 110kit on his 103. I think I've convinced him to just go with cams, mild head work and a good tune. I told him his engine would live a lot longer and his wallet would be a lot happier.

  After all I have been through, if I were faced with it now I would just buy an S&S 113 or 124 LC and get completely away from an HD Motor. Now I know that won't guarantee 100% success but pretty close. I feel bad for all the people that have had major issues and turned right around and traded for a new HD model only to have more issues.
