100" Big Bore Kit & Individual Cylinder Tuning

Let's review the stages of what turned into this 100" big bore kit and the challenges that we have to tackle with tuning your average Harley Davidson!
Check out the dyno graph at the end to see the HUGE INCREASES in horsepower and torque throughout the ENTIRE RPM RANGE. This was all with a MILD COMPRESSION build. ONLY 10.1:1 compression!

Wondering if you would get the same number if carburetated with Dave Mackie heads and a daytona twin tech t88c ignition module?

[@Cleanest5thgen]

Is this the magnetti marrelli efi

[@Cleanest5thgen]

Can the the magnetti marrelli efi be tuned like this and power this setup

[@keltingr2612]

let's hope not!

Were stock heads on bike on final run, already impressed eithway, but seems really high if stock

[@toolbrothers1477]

This 100 kit comes with new jugs.

[@geoffreyjones2000]

The picture shows S&S heads

[@TheRebelyellers]

I was wondering the same thing, those numbers indicate the heads were on during final dunk numbers but I don’t know why they failed to mention that....without the heads the 100” kit would still be well below 100hp

[@tenwalls2428]

Did I miss the year of the bike? Got the high mileage lower end comment , but didn't catch the year. Wondering about this S&S kit on post Tempkin cranks. Leaning strongly against it for post 2002 year models.

That’s some inside baseball stuff, wish I understood. You guys know your shit

[@geoffreyjones2000]

I was wondering how many hours does this install take on a professional level, sir?

[@2wheeldynoworks]

Installation takes about 8 hours, break in on the dyno takes another 2, and the individual cylinder tuning takes about 2.5 hours.

Hey man I really love how took care of this bike, I bought a 2005 roadking looking to do the same 100" big bore kit and was wondering where your located to get the bike tuned.

[@keltingr2612]

2005 has the pressed together junk crank, I wouldn't try a big bore kit

[@ALPHAFTUCK]

Can you please answer the questions put forth, as many are interested in the answers... including myself 👍

[@2wheeldynoworks]

It looks like all the previous questions were answered...

[@whitecapmadness7181]

Individual cylinder tuning? So it has a fuel injector for each cylinder?

[@Themoonman01244]

Yes

Where do I find tuned port injection for a Harley?
Mine just has one that feeds both cylinders.
What brand is it?

[@mattsinclair1244]

Hello what were the final dyno numbers?

[@vinjofin1972]

The video says 107 hp and 112 ftp torque

[@Manis-World]

What cams was this bike running?

[@geoffreyjones2000]

S&S .510" lift cam @3:17

@@geoffreyjones2000 that graph does not look like what the 510 cams put out

[@codylamaar]

@@Manis-World he said they did a big bore kit

[@johnnielsen5076]

Very true about compression...I wonder how many unsatisfying builds have been done over the years because of a lack of understanding about corrected compression?
