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.
