2012 Street Glide Thunderheader Install #3
3 of 3





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.

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...

Harley Davidson Lowside Motorcycle Crash
Customized Harley Bagger crash near the Rock Store. Great recovery, used momentum to land back on his feet then just walked away while bike was still crashing. Very lucky, he was uninjured except just a quarter size spot of road rash on his knee. AKA Harley Street Glide
