Could you tell us about installing the ATS? How much dizassembly was required? Did you have to use a wheel? 90 minutes sounds like it was pretty easy.
ATS is was intimindating to me because I associated it with Timing which it really is doing nothing to the timing gear. It is allowing the change to the timing mark for firing is all. Improvement was very noticiable on the low end just like theory giving a VERY good roll up when your say 2100 coming off throttle and want to accellerate without downshift. Couple with the VFCIII covering 3K+ you can see that across the board you have improvement and after moving back up to 91octane, no ping or only a occasional single ping and that was when I lugged it below 2K and went full throttle back out.
Installation is maybe a 2-3 on a scale of 1-5.
Tools needed are hex sockets for RT Floorboard mount, hex on cam cover, gasket scraper, 3/8" impact if possible, Wire brush to clean bolt, along with Red LocTite and Blue LocTite.
On the Vision, dropped the rear bolt of of the floorboard and loosend at first. It works but I found it easier cleaning the gasket by removing the front bolt of the floor board mount also. Cover that part of the fairing with a cloth to prevent scratches. (yes I have a mark)
-6 Hex bolts on cam wheel cover, ensure you got a socket adapter for your torque wrent for installation. Cam cover came off no problem, gasket was a little stuck. Careful cleaning and your done with that mess. Give cam cover some support while its off, no need to disconnect the pickup lines. Rubber gromment on back at the 9oclock position will come out. Ensure it is seated FIRMLY back in place when installing.
-Remove old gear using 3/8" impact for best results so no need to hold wheel while backing center bolt out. Gear will need to be encouraged off. Clean up center bolt threads with brush.
-ATS wheel. Two bolts hold wheel in place. I set at +4 degree, snugged down 1 bolt, removed other applying blue loctite and reinstalling. Same on other bolt then tighted. Install back on shaft, red loctite on bolt and torque. I used a plastic slip stick to apply counter tension to gear while torque it.
-Reinstall cam cover using Lloydz reusable cover gasket. Pay close attantion to the rubber grommet on the left side that it seats properly when snugging cover down. Torque as requried.
Start up, enjoy! These notes are my lessons learned and a few other riders I used to do mine. It really is not as bad as it looks and the only thing I had a prob with was the blasted grommet twisted so pulled the cover and reset it. Fine after that, no leaks. Lloydz gasket is thicker and like it says, reusable. The impact wrench made a breeze. Took 90 minutes from start because I rode it home and started in on it and she was still a bit warm. Took my time but easy project. Well worth the money spent!
