T500 500/Five - Spark Plug Wiring Orientation from Coil
Posted: Mon Jun 20, 2022 12:36 pm
I have owned my 1968 Suzuki 500/FIVE (short wheelbase) since I unpacked it from the crate in 1968 and assembled it at the dealership. The spark plug wires were always set (from the factory) to cross each other near the top of the frame before going to the plugs. In fact they could not easily be re-routed otherwise without re-threading them between the wiring harness and carb cabling and upper frame. When setting points and timing over the years many times, the setup was just like the manual indicates - nothing strange there. The bike always ran great this way (11,000+ miles) and in fact I never paid attention to that detail except I have the tank off now to re-line it and noticed it and thought it strange. Mind you, this bike is so original that it even has the factory silver foil stickers on the plug wiring! Intuitively, I would have expected the factory wiring to run from left coil to left plug and right coil to right plug. Has anyone run across something like this and does it matter? Thanks for input.
