Bought the Honda last year (my first one) now I'm in love, spent the winter doing some fix-up work. Previous owners didn't seem to understand metric hardware??
New muffler, new brakes, filters standard stuff.
Has run good this summer have about 150 miles on it, last trip drove it off the trailer and parked it, came back to clean it up and nothing, will not run. Spark seems weak, got it to fire on starting fluid and it sounds badly out of timing??
I have my service manual and am about to start with wiring checks as you all suggest. While I have all the plastic off to get to the wiring, my question is, is valve adjustment pretty straight foreword or is it best left to the shop?
Also, to check compression the manual says to warm up the engine first then check for 192, any idea where it should be cold sense I can't run it to warm up?

Valve adjustment

Cold compression should be anywhere from 100 to 140psi

fuel pump

That's one of the few bikes with a fuel pump.... check (as in drain screw) if there is fuel in the carb... if not you can run a test tank as long as it's higher than the carb and see if it will run using gravity feed straight to the carb inlet. If it does, the fuel pump, relay, fuse and or controller for it may be the issue.......

found the coil did not ohm check so have that on order. could not check the cdi, the guys at the local honda shop don't think there is any way to bench check them. Not sure why they give a chart in the service manual. did find a hole in the back side sealant so if it isn't bad it will be sometime when I get wet, so I have one of them on order also. Set the valve clearance was surprised to find them all very tight had to open all 4 to get the .003. Fuel pump is fine next up oil change, fuel filter change, and rework some rotted vent lines while I wait for parts.

GReat job man keep up the restoration.... as far as checking the CDI yes you can just FYI the Honda guy would rather put on a new one than check an old one.
