starter solinoide either has bad connection or needs replacing ! battery could also be low on charge !

check and clean contact breaker points (contact set) get a fine sand paper in between the contact and rub it a little, after use dry cloth or paper. end of story

with the snals not flashing it might ne the indicator relay, with the front brake light check he wires on the switch just under the front bkake lever

timing is out

If it is a belt drive it may be slipping do to a slack ajustment causing heat.

I think honda only sells the complete crank as you have been told.
An expert engine machinist may be able to dissasemble the crank rebuild the journals, grind, source oversize\undersize bearings, refit bearings, reassemble and balance, but the time and cost would be more than a crank.
You may chase a second hand one from a bike breaker, personally I would try to find another motor, as if the big end has gone, there will be wear in other areas of the motor, like the cam bearings which also are not replaceable. It must have had an oil problem..

it does not have a kill switch?
starting point would to look at starter wires to key switch see if they are pinched in the gas tank area or in the handle bars,
if all looks good replace the switch

Use Google website to download a wiring diagram.

I would just match up some aftermarket breather tube....probably cheaper.

crud in the tank/reserve switch

The crankcase oil capacity is between 1 and 1.5 quarts.

thats easy

the gear oil is the engine oil kept in the sump at th bottom of the engine

Install a turbo or nitrous injection system. Or both.

Never assume anything is fine without replacing it.
Replace the plug, cap and wire before eliminating them!
There's a resistor in the cap that can burn out, and though the cap may look fine and even allow spark through (because it jumps the resistor) the cap may still be bad.

1. Have you checked all electrical wirings that supplies the coil and relays, are all wires in good conditions?
2. Have you checked the main fuse (normally a 30A ones) located along the "+" (Red electrical cable from your battery).
3.Have you checked the secondary fuses, normally you would have 3 to 6 fuses for different electrical function, ie,. turn siggnal, horn, headlight, etc. located either by you RH cover or near your gauges.
4. To do all those you may need to use an Ohm meter to test their continuitis.
Cheers.
