103" Streetglide w/ Thunderheader and Woods TW-7H cams
This is the latest greatest rendition of my scooter. I got rid of my true duals and picked up a used Thunderheader off eBay. I also got rid of my Andrews 31's and went with a pair of Woods TW-7H's along with a set of Woods directional lifters and a set of SE tapered adjustable pushrods.The heads have a street port and polish with stock valves and a little cut to Boost compression slightly. CCP is about 205# with these Woods cams. Tuned by Jason at Faribault H-D with a SE Pro Super Tuner and DynoJet Dyno. 100 HP and 115 TQ with SAE cf with no torque dip in the midrange! I did bend two of the baffle vanes all the way out on the Thundercone to achieve this and probably gave up a couple HP, but the torque curve is great. Bike had 40,000 miles on it when I did all this earlier this summer; rode it to the west coast after the mods. Two-up, fast, mountains, hot weather, tourpack with a big T-bag on top of it.... Used maybe a cup of oil in 4000 miles. 20W60 Redline. Baisely oil pressure spring and plunger.

No discs to remove, No unbolting, No Dirty mufflers to reach inside and turn Just a simple adjustment. Click for sound demonstation: More Power Patriot Defenders feature a Step Pipe design that promotes Exhaust velocity while reducing reversion that can dilute the intake charge. By utilizing these technologies in conjunction with a formed merge collector and a state of the art perforated muffler core, Patriots engineers have developed an Exhaust system that performs on a par with other top brands for horsepower and torque while offering the on the fly volume changes of the SFI Valve and Superior Stainless Steel Construction. Easy Volume Changes! Defenders are constructed from Highly Polished, Corrosion Proof 304 Stainless Steel with Beautifully Chromed Full Coverage Heat Shields and feature a Tightly Rolled Tip with a Domed Interior for a Beautifully Unique Look. In the Closed Position, Defenders will generally replicate stock sound levels. As you open the SFI valve, sound levels and power output, will increase, with a Deep, Throaty Rumble that rivals any pipe on the market for great sound and significant power increases. *SFI stands for Sound Flow Inversion, Patriots innovative Exhaust baffle design that allows the rider to redirect the flow of the Exhaust to instantly change the volume. In 1996 the first generation of SFI Slip On mufflers were produced for Harleys and quickly became a big seller. In 2005 Engineering work began on incorporating the SFI Technology in to a performance Exhaust system. That engineering effort culminated in the line of pipes now known as the Patriot Defenders.

Installation generally takes less than one hour and the Top Fueler is designed with a failsafe mode that most brands do not have; should the Top Fueler ever fail, it will revert to the factory stock settings instead of leaving you stranded on the side of the road.





Rolling smoker
I built the engine on this bike and when it was time for a new tire, the customer wanted me to burn up the old one. I happily obliged. What kind of person would not enjoy a burn out? The bike owner is also the camera man. He is laughing at the end. I guess you can call that a happy customer. And I am just doing my job. If only I got paid to do wheelies...
