The first time I heard this was on this forum with an all too common situation. A new member purchases a vrod attracted by the hose power figures, and promoted as the most aggressive bike Harley ever made.
After a month or so of hard riding, which the revo takes willingly, the user wants a new set of cams to eek out a little more power. The Porsche designed motor with liquid cooling hinting that more is in bag just within reach.
Some are lucky enough to find a use or new old stock set of SE2 cams while others are present for the latest Jones Cam group buy, usually prompted after a large influx of new members build the pool up to a manageable number to off-set the production cost. But there are getting harder and harder to set up and most don’t get their cams then quickly fade away trading their vrod, down and away for another model.
Others are little more persistent and turn to a forced induction set up which nets a substantial horsepower increase. Even more persistent are those willing to push things a bit further with a set of oversize heads and cams to add to their forced induction set up.
The number further decreases in size and the scope of work increases in complexity for those willing to undertake a bored motor project. Motor removal and disassembly is required along with a machine shop to increase the bore diameter. All new internals are required plus a few extras to increase the strength and rigidity of the case. Either the willingness to pay or a mechanical proneness is required to undertake this feat. Stroking the motor is no different and slightly more complex requiring not only motor removal, machining and the new components, but the stock crank has to be sent out, re-welded and ground to the requested stroke.
Now we arrive at the one out of a thousand build; very patient, tenacious, un-compromising resolution and a lot of luck. I am within spitting distance of this goal having taken over 5 years to amass 90% of the needed parts. I’ve had to deal with life changing events that set me back months, and years but still maintained slow steady progress forward.
V-rods are hard as hell to build, parts aren’t available, knowledge is scarce (from the harley shops anyway), and support is minimal. This forum and its members have been a fantastic resource supporting this, willing to help out fellow members, either through knowledge sharing, a general discussion or the discounted liquidation of parts following their own life event. I myself have contributed as much as I can, giving my unused parts away for shipping costs when I can or providing guidance when I can.
At the center piece of my accumulated part lies the legendary 3/8 inch stoke Falicon full circle billet crank (Courtesy of Okieboy) machined from a single block of steel and continuing the counter weights around the full 360 degree radius of the crank. Besides its massive stroke, and superior strength (and weight), the full circle design allows the crank to retain more speed with the full circle portion acting as added flywheels for smoother revving and more torque. Ceramic coated CP pistons, along with Carrillo H-beam rods will be anchored in place to this gorgeously machined crank by a Fitzgerald crank brace and billet oil pan.
On the top end, 2mm oversize intake and 1.8mm oversize exhaust valves will be driven by Jones Stage 3 N/A cams. A Fitzgerald 58mm throttle body will control the airflow, while the Motohoolignas air box provides a maximal surface area to supply clean filtered air restriction free.
To transmit the power to the wheels a fully built transmission, with straight cut, harden gears will be dropped into the case and a Holymoto billet clutch basket will house an AIM lockup clutch.
While I am mechanically inclined I cannot assemble this on my own. The machine work, boring, and assembly will be conducted by Fitzgerald Motorsports and I will remove and install the motor once it’s complete. I’ve talked to Scott for years now panning and prepping for this; he is a great person, fun to chat with about all things vrod and i know my motor is in some very powerful, knowledgeable hands.
This is my final push with all the parts crated and transportation arranged for this week.
The build and displacement is a 1487.
