Try replacing your spark plug caps and your spark plugs. A bad resister in a cap could be causing the misfire. Purchase NGK brand replacement spark plug caps, they are the same as the original caps but will only cost $5 a piece instead of $30 each. The caps simply unscrew off of the end of the wires.
check the coils to see if there is any spark from there,if not start going backwards to the spark rectifires,the points or cdi (which ever you have)
if they are all working check the wires , lots of places to look just start at the pulgs and work your way back, don't forget to check all the grounds
The fuse on the starter solenoid is the main fuse for the bike. If that fuse was removed and replaced with a wire, you could melt down the entire harness or even burn up the cycle. The short that was popping the fuse has probably melted part of the harness or popped fuses in another part of the bike. Start checking in the main fuse box in the fake tank for shorts. Also check the solenoid with the main fuse for melt down, good luck.
Obviously the CDI is picking up power from the starter button. Check the ignition key switch for proper operation. Chances are that whatever fried the loom also fried part of the switch. Alternate to that, trace the wire powering the CDI system, disconnect it at the source (starter button connection), then find a power source that is live only when the key is turned on and then hook the CDI wire up there.
Moisture is not likely to be the problem. Though trying to help, your friend made problems worse by messing with the carbs. The backfire is caused by incorrect carbbalancing and incorrect carbsynchronization. Your bike is 27 years old. The Honda shop probably will not work on it but you could ask. If the shop won't fix it then ask if any of the mechanics work on bikes at home. Any chance your friend messed with the spark plug wires?
Your described problem based on the bike being a 1982 model could be varied, among them are:
weak spark - not necessarily weak battery. Culprits could be loose loose connector to the CDI, low IGN +12 to the + terminal of the coil (check with a voltmeter while just switch on and when cranking/starting), or even a loose ground terminal. Check spark by removing plugs, reconnect the plugwires, let the threaded end touch metal part of engine, crank. Sparks should be strong;
corroded/poor contacts in the ignition switch resulting to the above. You can test by running a jumper wire straight from the battery to the + terminals of the ignition coil;
too lean air/fuel - plugs should be brownish in color;
air or vacuum leak - resulting to the above and high or poor idling;
unbalanced carbs - carb check/clean, verify air adjustment screw number of turns,
compression low - have a compression check.
Would look forward to your updates. Good luck and thank you for using FixYa.
