The latest Adjustable Cam Gear install on a 120R engine.
This engine was built and tuned by a local HD Dealer. They suggested
to the customer that he come see me if he wanted to squeeze
out a little more power. The customer watch while I installed
the adjustable cam gear and retuned the engine.

Nitrous explosion at dyno shootout

I rode my bike to Daytona Bike Week, entered the WyoTech Institute Brute Horsepower Shootout just for fun (not seriously thinking that I would win with the competition that was there).

First Place in the V-Twin Unlimited Class

Keep this in mind:
You can't compare dyno graphs from different dynamometers
and get true comparisons. There are a lot of dyno graphs on
the internet that boast astronomical numbers. One graph that you
can compare is to a graph with before and after results, but you
still can't compare the numbers to other dynamometers.
Even then, the numbers can be inflated. Instead of looking
at the numbers posted, look at the amount of gain between
the before and after. I like to also use the percentage gains.
When looking at a graph, the peak HP @ TQ is important,
but more importantly is the location and climb of the graph.
Look at RPM where that the TQ starts, how steep the TQ line
is, where the TQ peaks and where the HP starts to drop off.
Remember that the formula that dynamometers use to
calculate HP is "TQ x RPM / 5252 = HP" which means
that when you raise the TQ...the HP has to follow.

I perform dyno tuning for local motorcycle shops and dealers around this area. If you want me to tune your bike at another shop's location, have the shop contact me. I also offer dealer discounts on dyno tuning and products.
Dyno tuning is what I specialize in, so why not have a specialist tune your bike.
