Getting that oil leak fixed apparently was a high priority as Stan got to work on the engine basically replacing anything and everything he could. The 80” Evo engine got bored and stroked until it encapsulated 103-cubic-inches of combustion space along with a lot of other high-performance details. That high-performance aspect is not a big surprise as we previously featured a 202 horsepower (yes 202hp!) bagger Stan built in the old print magazine. Although I don’t know what this baby is putting out, with a Weber DCOE carb and a header-wrapped Thunderheader exhaust opening and closing the doors to the 103-inches of firepower and all of Stan’s usual tricks in between, it’s got to be pretty substantial. And remember, you can’t spell substantial without Stan.

There are some other cool touches that take this out of “That’s just a Fat Boy engine” like the 3” Karata Enterprises belt drive that passes on the power to a stock H-D 5-speed or maybe that tall hand shifter with a hydraulic foot clutch and a little ol’ six-shooter on the shift linkage. That pistola could bring a whole new meaning to banging a gear, but I’ll have to assume it’s been made inoperable. But even though all of this engine stuff is way cool, that isn’t what takes it out of the “I can’t believe it’s not butter” Fat Boy category.

Messing with the stock H-D frame and bodywork is where Stan really shined on this project. He whacked away at the frame until it was long and low like no Fat Boy before it. Stan modestly said, “We set out to make a cool bike and wanted to use a familiar platform base. We built that swingarm for a 240 tire that fit the design followed by the rear fender. We continued the theme into the oil tank which doubles as an air splitter behind the front wheel. A final touch was cutting the frame and adding some needed rake totaling 47-degrees with the trees. The final product is as you see a pretty sweet low Fat Boy. I particularly like the lines. It’s very shapely.”

And for all you naysayers of customs, it’s a real rider. “The bike has already made it to Arlington, Texas, after the build and is ridden quite regularly. The bike handles extremely well and it’s easy to operate with one hand on the jockey and one on the bars. It’s very stable at all speeds,” said Stan. “I feel we have accomplished our task and the customer is very satisfied. He loves the makeover and doesn’t mind the photo ops he constantly finds himself in. For us, that’s the ultimate flattery.”

By the way, there’s no word on whether the oil leak ever got fixed, but I’ll assume it has. For more info on Flatline Customs, visit www.flatlinecustoms.com and be sure to scroll down the home page for some interesting dyno runs.
