Bike runs on two cylinders after warmup
I have a 1983 interstate that for the last year been trying to find problem
Here is what I have done so far.replaced coils ,spark units ,reworked carbs, and reset valves,new hotter sparkplugs,spark plug wires, new fuel pump and filter and gas lines.steam cleaned fuel tank. New brake pads and caliper kits, tires , cleaned all connections replased lights for led and new flasher.
Recleared old paint..
It runs good for maybe 20 miles on a warm day and starts missing loses power when I let off throttle and throttle back it tries to come back but will not I stop and let it cool off and it come back.but when the temp outside is at or below 74 it will not breakdown this has me stumped and I also had super cycle in Joplin mo try to find problem and no luck he pressure tested pump it was right and tested all he knew to test.but don't think he tested final coil to see what it was doing.any ideas please I have tried everything I can think of
