Hey guys, I just balanced my throttle bodies tonight. If you can balance carbs, you can do this.
Triumph sell a wiring and hose kit to extend the reach from the bike to the tank. It is stupidly overpriced. You don't need it! I put my bike on the centerstand right next to the work bench in my shop and put the tank on the bench. Get the bike as close as you can and the fuel and power will connect right up. You don't need to worry about connecting the drain/rollover hoses nor the fuel sender connector.
After you get the tank off, you need to remove the airbox. This is easy, remove the two bolts on the back of the box and lift it off. You will need to disconnect the breather hose (bottom rear right), electrical connector (bottom front right) and pressure hose to the computer (right middle).
After you get the airbox off, you will see the air idle hoses and valve. Unbolt the valve from its mount and move it out of the way, and disconnect the hoses. Connect the hoses from your gauges (I used a Motion Pro mercury gauge) to the ports and start the bike. You will have to hold the throttle slightly open to keep it running, but it will start with all those wires disconnected. Kinda makes you wonder if you need 'em in the first place!
To sync the throttles, remember that the #1 cylinder (left side) is non-adjustable. Sync the #2 throttle to #1 by adjusting the screw between these cylinders. Once those match, sync #3 to #1 with the other adjusting screw. You might have to repeat the process a couple of times and don't forget to blip the throttle between adjustments to let the linkage settle.
Once the gauges are matched, put it back together, you're done! Check carefully that all the connectors are married up as the tank is a bit of a PITA to pull off again. My EFI light came on for a few starts probably due to readings out of range from the disconnected sensors, but it will reset itself.
Easy! Don't let the shop rake you over the coals for this. It's way cheaper to buy or beg a gauge and do it yourself.
