01. We left off last issue with Kazoo about to install the heads. After setting up the squish (see sidebar) Kazoo installed Cometic Multi Layer Steel (MLS) head gaskets and then installed the heads. The MLS gaskets are made up of three layers of stainless steel. The outer layers are embossed in a 0.001-inch–thick viton rubber to help provide a quality seal and corrosion resistance.

Last issue we started off a two-part engine hop-up at Freedom Cycles in Anaheim, California. In that issue we showed the displacement of an ’08 Electra Glide being increased to 103 ci using Küryakyn’s Cheap Thrills Kit. The Cheap Thrills Kit, $889.99, (prices vary depending on model) includes Wild Things cams and pistons as well as the necessary hardware and gaskets. It should be noted that last issue we gave the specs for the Wild Things TC-26D cams that were installed; these were high-lift cams with a 0.575 intake. The owner of the bike, Devin, is sort of a curious cat and likes to experiment with different changes to his engine. So the high-lift cams were utilized with the knowledge that in the near future the top end would come off to see what results would come of the higher lift TC-26 cams and some head work. Knowing that 0.575-inch lift is extreme for most stock heads, Freedom Cycles tech Kazoo made sure everything would work by checking for spring coil bind and checking for clearance to the top of the seal. For a truly bolt-in application with no worries, Küryakyn recommends its TC-2D Wild Things cams. The TC-2D cams have a 0.510-inch lift on the intake, have the exact same timing as the TC-26, and according to Küryakyn, can achieve really good performance results.
02. After both heads were torqued to spec, Kazoo re-installed the stock throttle body.

In this issue we are going to button up the top end and finish off the install with Küryakyn’s Perfect Storm kit, $1,676.99, which includes Crusher True Dual head pipes, and mufflers, Hi-Five Mach 2 air cleaner assembly, and the TTS MasterTune engine management system. As with the Cheap Thrills kit, the head pipes, mufflers, and air cleaner assembly were designed and heavily tested to achieve the best performance results by Küryakyn’s Performance Division Manager and engine guru, Mike Roland.
03. Then moving back to the heads, Kazoo placed the rocker arm housing gaskets on top of the heads.

While bagger guys will go to a 2-into-1 when looking for performance, most owners like the balanced look of duals. With that knowledge in mind, Mike set out to design a set of true duals that would perform as good as most of the 2-into-1 systems on the market, work equally well on highly modified or stock bikes, produce a broad power band, not have a dip in the torque curve, and have a nice deep sound without any high frequencies. To get the performance he wanted, Mike used wave tuning which utilizes the pressure pulses in the exhaust. By incorporating a unique chamber at the front of the muffler, he was able to separate the primary and secondary tuning in the exhaust system so that the muffler acted as a secondary tuning device. The chamber design also acts as an anti-reversionary device and Mike used the chamber to balance volume against the backpressure of the baffle to further shape the torque curve. To get the desired sound, Mike used acoustic tuning to determine the size and how many holes per-square-inch would be necessary in the perforated baffles. Acoustic tuning was also used to determine the coarseness of the stainless steel wool packing that would also be necessary to achieve the sound he was after. Aside from helping to get the sound, Mike has found stainless steel wool packing won’t burn up or rust and doesn’t break up or blow out like fiberglass.
07. Kazoo then installed the rocker arm supports and breather valve assemblies and torqued them to spec. As we mentioned earlier, since he was installing such high-lift cams, he made sure there were no issues with clearance or coil bind.

The Hi-Five Mach 2 air cleaner was designed as an extremely high-flow unit to supply the engine of a stock or highly modified engine with plenty of air to help achieve strong horsepower. Tying it all together and getting the bike to run properly, the Perfect Storm kit comes with a TTS Mastertune engine management system. This unit was chosen to complete the package because TTS Mastertune has a long history and extensive experience that involves actually tuning the ECU, as opposed to working as an add-on device. With its wide range of options and tuning capabilities the system can be as in-depth or as basic as the user/tuner wants or needs. Küryakyn has a large library of calibration available for their combinations on its website.
Follow along as we watch Kazoo button up the second part of the build, and after some break-in miles, the bike makes a run on the dyno for some final results. HB
