did you drain the carb's tub and gas came out? (so it's 100% not dry, right?)
ok, then try this:
- turn on all switches as if ready to start bike (place in neutral)
- grab some jumper cables, attach to cars battery
(car, not huge truck, w/engine turned off)
- attach (-) negative end to the engines clutch lever
- then attach the (+) positive end to a large screwdriver that you will
briefly use to touch the bikes electric starter's (+) cable/nut end with,
see the black rubber cap in the pic? expose that and touch (+) there.
- this direct jolt of current to the starter
should start the bike
if all electrical is well; this produces a strong spark and crank to
the starter; if not maybe your footstand or neutral switch is busted, dunno.
