Got all the tupperware panels, lights, seat, frame etc all off my K6 Exec for a thorough cleanup & repaint (replaced Primary Pulley Shaft Adapter bolt, all fluids changed, plugs cleaned & gapped, brakes cleaned & fresh fluid installed, radiator flushed etc) Should the engine be able to run without all this paraphenalia? Starter just 'clunks' but won't crank the motor - even with a direct heavy wire to the + battery terminal. Instrument cluster lights up. All fuses I can find check out OK. side stand is UP, kill switch closed & both brake levers applied! Bike is on centre stand (I can't find any cutout switch on centre stand). Battery holds 12.5v plus, and is normally on battery tender when not in use. How can I be sure plug caps are seated OK; they feel to have a hard contact on their terminals, but the rubber shrouds give a degree of uncertainty!. 54,000kms on the odometer. Any helpful comments appreciated.
