the high-performance journey

@TylerGreenblatt For most of us, souping up our bikes is more of a journey that involves installing and enjoying one performance upgrade at a time Thankfully, however, this isn’t something that we have to live with. The options for those looking for more power are seemingly endless, argu-ably outrageous, and, more often than not, expensive. Performancing your American V-twin can be as simple as spending a few hours bolting on parts in the garage, or boxing up and send-ing your engine to one of the premiere performance shops in the country to work its magic. For most of us, souping up our bikes is more of a journey that involves installing and enjoying one perfor-mance upgrade at a time. I’ve always found it to be more fun to do a little bit at…

All that time on the dyno costs money My immediate reply was: “No. Horsepower Costs Money!” Then, as the issue started coming together, again and again I learned more about what I had stated. Not to say that you can’t make small, inexpensive changes to an engine and be rewarded with increased power output, but usually the rewards have a correlation to how much is spent. For example, on page 64 I was on hand for the engine build of the STAR Power Thrasher 107" 130 hp Twin Cam. STAR Power owner George Bryce proclaimed what might be the defining statement about the horsepower-per-dollar theory: “You want 50 more hors-es? That’ll cost five grand. You want 60 horses (merely another 10 hp)? That’ll cost 10 grand.” You might be thinking, “Wait a…

Requiem for the XR1200 I took this photo at the Road America Raceway in Elkhart Lake, Wisconsin. When I saw your post about putting together an issue on American power, I couldn’t help but lament the fact that The Motor Company discontinued the model. Those high-performance Sportsters were a great class of bikes, and watching the road races actually inspired me to buy a XR. The look and feel are unlike any other Harley I’ve ever ridden, and that pushrod motor kept up with many a OHC sport bike.

I have always been a WWII history buff and love the stories about how they came up with the names and nose art for the bombers. The artwork on the tank…

powersledgehammer sledgehammer

Think about this for a minute: you’re rolling down the highway on your Sportster at, oh, maybe 70 mph, and then you get rear-ended by a runaway freightliner do-ing the “ton.” That’s what this Sportster feels like when you really roll on the throttle. At about 3/4-twist, the turbo is pounding out 10 pounds of boost and right at that moment, another 40 hp or so from the nitrous kit kicks in. Sledgehammer all right—right to the back of your head. It’s a beast. It’s so much of a beast, owner Rodney Lyman and his best bud Daniel Berden have never used the obvious nitrous kit on the dyno. They’re only guesstimating the power output at around 200 on full boost and with the NX system “on” (if you’ve ever tried…

the color of happiness

According to some quick Internet research, if a person’s favorite color is yellow, he is likely to have a happy disposition and are cheerful and fun to be with. Not sure that holds true for Mark Dahl of Bismarck, North Dakota, but he’s a fan of the sunny color, and he’s plenty happy with his custom 2005 Harley-Davidson CVO. It was intended to look stock, but it’s far from the original factory Custom Vehicle Operations (CVO) design. It’s loaded with hop-up goodies that give it a good dose of muscle. Since he was a kid, Mark’s color of choice has always been yellow. Many of his motorcycles have been finished in the hue, and when Harley-Davidson unveiled the 2005 CVO in yellow, Mark had to have one. Un-derstanding they would be…

the right side

Matt Anderson spends his days building custom bikes at Gilby’s Street Department in River Falls, Wisconsin (Matt happens to be the shop manager). Gilby’s has a great reputation for high-quality work; they do pretty much everything in house (save for chrome plating), and it’s clearly a busy place. And since Matt manages the operation, he’s equally as busy. That doesn’t stop him from building his own bikes. The majority of those machines have been over-the-top nice, but the ’82 FXRS spread out in the pages in front of you happens to be extra-special. How special? Look closely at the photographs. See that Weber carburetor hanging out on the left side of the machine? Carbs for Harley-Davidsons are typically on the right. Getting it over to that side of the motorcycle isn’t exactly…
