124 Inch Twin Cam Engine NEWS

 

We have developed our own version of the awesome 124 inch Twin Cam engine.


We take your Twin cam engine, pull it from your bike, tear it down, bore the cases out to fit the big bore cylinders (4.125), install the Billet 3 piece

stroker crank from S&S, install the TC3 oil pump and cam plate, use our .680 lift gear drive cams, install and machine your heads, (110s) are even better,

with big ports and big valves. This kit includes the newest HPI 62mm throttle body with additional portwork on manifold, new big flow injectors, S&S

premium lifters and pushrods, clutch lock up and spring, fully assembled and tuned to perfection. With your D&D Boarzilla pipe, Big flow air cleaner and

the TTS tuner, we will make over 160 hp and 160 foot pounds. Installed and ready to go for 9,995.00. Will need to add Boarzilla, TTS or Screaming Eagle

tuner.

 


 

 

 

Everyday folks contact us wanting to know how to make more power from the awesome S&S 124.

Here are a couple photos of how the intake and exhaust ports look when we get them.

As you can see, they are very restrictive. We improve the shape, size and valve job, to add 12 to 17 more horsepower.

We do offer upgrades to get over 150 hp from a Streetable 124.

 

 

 

 

 

 

Our goal with, "The Adventures of Farm Bike", was to create a real, streetable Harley Bagger, with real bolt on parts,stock bottom end,

Harley heads and cylinders, (your stock parts modified), stock wheels and brakes, stock belt, no air shifter, foot shift only,

93 octane gas station gas, stock Harley hand clutch, stock weight, 200 lbs rider (suited), stock EFI, all motor, less than 100 cubes,

less than $9,000.00 total budget, 10 second quarter mile Bagger.

By the Grace of GOD Almighty, with His Gifts of talents and abilities, our mission is accomplished!!! 
Now, we start on a new mission, to try our best to go the quickest possible at stock weight, foot shifted stock rear belt.

More info to follow ????????

Why do we recommend Boarzilla 2into1 pipes for our "Thrasher" builds?


Because the market is full of small to tiny head pipes.

1st photo is of VHR style head pipes.

2nd photo is of the Boarzilla.

See how the stock exhaust valve will not even slide into the small pipe? Same valve fits loosely into the big pipes.

That fact does not seem to matter much when you have "stockish" 80 horsepower.

But it makes big difference in our 130 to 150 hp ranges.

Thundering Thursday engine of the week!! 150 cubic inch Twin Cam for a 2016 Road King. This is the 3rd one we have sold.

This will fit in a stock "Touring" chassis. Would I tour with it? Nah. But is FAST! Can make 200 hp and 180 torque.

Smiles per gallon ????????????

We just finished the ultimate sleeper. SofaGlide 113. We picked him up 51 hp and 26 foot pounds. It looks like a bone stock CVO with a pipe.

58mm throttle body, 113 Pistons, .650+, 120R Valves in the 110 heads, our big flow, high speed ports, Boarzilla, stock air cleaner and TTS smooth tune.

The curve is so smooth. Let us do one for you soon! ??????
