Most Honda bikes of the 1980's had small fuse boxes with 3-4 fuses at the most. Usually 1 for ignition and charging, 1 for Headlight Only, and 1 for All other lights. Overheated and even melted fuse blocks are commonplace in these years due to high current draw and the plastic block which melts and distorts over time, breaking the circuit to the lights. Replace all 3 or 4 circuits of the old fuse block with modern in-line blade-type fuses and this will never happen again. (If the fuses are all good, and the plastic box is not melted or burnt, you may have a bad Ignition Switch, but this is rare)
My night hawlk go 0 to 60 no problem when I get on
Sounds like no timing advance. Will seem to go well up to about 55 or 60, but will run flat or even slow down above 60. Follow shop manual procedures for verifying timing advance operation. If you watch the timing mark with a conventional timing light, you will most likely discover the mark will not move when you rev the throttle. If this is the case, you must replace the electronic timing pickup or module. Consult shop manual for the correct procedure.

How do I be replaced the rods in my 1986 honda
Hate to sound like a smart $$s but if you have got to ask then you don't have the tools or mechanical knowledge to do the work.

This is not a simple repair and it's costly certainly it will cost more to repair then what you could get another bike for

Your key code is on the helmet lock, the tumblers of the ignition, and on the underside of the gas cap. It is a six digit code the last three of which are the code( xxxA56). If you take a 10 mm socket and a long extension you can reach up underneath the lock, remove the two mounting bolts, and pull the lock out the bottom. Most motorcycles have a headlight with a mounting bolt on each side. By taking one of these bolts you can usually swing the headlight or in this case the fairing out of the way. Removal of the switch may not be necessary to read the key code(Honda usually stamps it facing the frame neck). One key fits all the locks on the bike if no locks have been changed.

A service manual is a valuable tool with an aging bike. I suggest the
dealer/mfr. or Clymer books. In the meantime, go to the library
reference section...646 stacks should have what you need.
