Finding no issues, he installed the cover following the tightening sequence and torque in the service manual to complete the cam install.  14. Back in our Houston garage...  14. Back in our Houston garage we worked on the air cleaner and pipe install. This close up photo shows how the air cleaner cover trap door works. When closed in rain or cold weather, intake air comes from the motor side of the cover. Also note how Yuill Bros thoughtfully added hand written instructions on some of the parts.  15. To install the new air...  15. To install the new air cleaner, we completely removed the stock air cleaner, backplate, and breather bolts. We also took a second to clean the inside of the induction module with carburetor cleaner.  16. We installed the Yuill...  16. We installed the Yuill Bros supplied Screamin' Eagle backplate by adding new o-rings to the backplate at the breather holes, loosely inserting the breather bolts, then attaching the backplate to the induction module with the supplied air filter posts. On all bolts, we used some blue threadlocker and torqued them to spec.  17. Next, we inserted the...  17. Next, we inserted the supplied rubber breather tubes into the breather holes and mounted the Yuill Bros plate to the SE backplate. Note the large hole in the rear of the plate to direct fresh air onto the rear cylinder (arrow).  18. We attached the high...  18.

Finally we installed the chrome flame cover by aligning the dowel pins with the holes in the mounting plate and secured with the supplied center bolt. The Yuill Bros air cleaner is an attractive and highly functional addition that will draw attention.  20. To install the Yuill...  20. To install the Yuill Bros Elite D Exhaust System, we first raised the bike and secured it. Then we removed the seat and disconnected the negative battery terminal. Next, we removed the saddlebags, the right side floorboard and brackets, and the complete existing exhaust system. Then we removed the existing exhaust port gaskets and installed new James gaskets.  21. Next, we transferred...  21. Next, we transferred the OEM exhaust flanges, retaining rings and O2 sensors from the existing pipes (top) to the new Yuill Bros. headers (bottom).  22. Then we removed the OEM...  22. Then we removed the OEM starter bracket and installed the new starter bracket using the OEM bolts. Next, we installed the new "L" tab to the starter bracket and followed the instructions for the rest of the pipe installation.  23. We used a straight edge...  23. We used a straight edge to align the mufflers.  24. Now it's time to install...  24. Now it's time to install the proper ECM map for this combination of parts. After installing the TTS software we connected the PC to the ECM diagnostic port using the TTS interface and cables.  25. We opened the MasterTune-HD...  25. We opened the MasterTune-HD program then opened the calibration file. You can verify this by selecting "Edit File Comments" which should show you the year, make, model, and components for your calibration.  26. Next, under the "File"...  26. Next, under the "File" command we selected "Program ECM". In the pop up box we selected the "Get ECM Info" button to confirm communication with the ECM. Finally, we selected the "Program ECM Cal" button to upload the calibration file and the installation was complete.  27. Here's the complete Yuill...  27. Here's the complete Yuill Bros. Stage 2 kit installed. No complaints from the looks department. Right off the bat the bike ran fine with no hiccups and we could immediately notice the added power. Next month we'll follow up with more info on the MasterTune program and take the bike over to The Dyno Difference to get some fine tuning and final dyno numbers.
