Gen5 ,T-body sync
I had to replace a T-body because the bike starting to had bad hesitation when you get on the throttle. After installation, I did a T-body sync for idle. Although it made the Idle smooth, it did help on On/Off throttle too. I didn't think that it can make so much different on the smoothness of throttle transition.
I use a motion pro tool for synchronization. first had to calibrate the tool by connecting all 4 vacuum hoses from the tool to the hose from the T-body to EVAP system. start the bike and run it at idle and by turning the screws on the tool adjust all 4 port height the same.
After that connecting hoses on the tool to each port and run the bike at idle again and adjust each port tell all the bars on the tool are the same height. because I have woolich and setting the idle higher than a stock bike had to turn the screws out more till I get the correct vacuum.
few pictures from the T-body.
