If it isn't pinging on heavy throttle at low RPM I doubt the high octane fuel would do anything other than lighten your wallet faster.

Sounds like 7volt regulator might be putting out too many volts. This powers the fuel and temp gauges.

Hi Mario, Here's the circuit I came up with... Disconnect low fuel light at the sensor and insert this circuit, Also needs AUX power from the fusebox. Comparator is LM 339 (4 comparators in one package, unused inputs grounded). Transistor I used is TIP42 'cause that's what I had handy, any garden-va...

Don't think it's hydrolocked, but you can confirm this by unscrewing the sparkplugs, put a rag over the sparkplug holes and then try the starter. If it was hydrolocked you will get a spray of whatever was locking the engine into the rags. If it still doesn't turn over without sparkplugs you have oth...

I haven't had a Goldwing engine apart to this extent, and the parts fiche doesn't show it, but in most cases there's a snap ring on either end of the wrist pin in the piston, remove the snap ring and you can slide the wrist pin out of the piston. Unless there's a hole in one of your pistons or other...

Per FSM the 1500 radiator caps are rated 11-15 PSI, I wouldn't exceed that, you could create more leaks that weren't there to begin with. You could just refill with water for the test, and add some of that leak detector stuff that glows with UV light. Your local Auto Parts is likely to have both the...

I have the 1500 Haynes manual which is no small tome, handy to have nearby in the garage, but also refer frequently to the FSM. It's only some 90,000,000 bytes of PDF. Thus the old computer in the corner of the garage....

You can certainly run without a temperature gauge, there's another way to tell the temperature anyway - Steam = overheated. :lol: Not sure what you mean by "lost", if the sensor is missing you will need to find something to plug the hole to keep coolant in the engine.... but the engine does not requ...

I have considered that several times, but sat down and designed this little circuit out of boredom.

I could substitute a potentiometer for the voltage divider, that way if the sensor gets weaker I could adjust for it until it completely gives up....

Speed sensor is a Hall Effect sensor inside the speedometer. Its output is used by the cruise control and the turn signal cancel unit.

Probably the easiest place to access that signal is HERE: (Cruise control unit is under the seat.)

The "Low Fuel" light on my 1500 works, but when it comes on it is so dim it can hardly be seen. So I breadboarded up a circuit to detect this and light the bulb brightly. I determined the Low Fuel bulb only sees about 5 volts or so when it comes on. That's pretty dim. So this circuit puts full volta...

Cracked hose is the crankcase vent - it goes up to the air box. Not critical. Wouldn't hurt to replace it some time though.

If the fuel tank is near full fuel can gravity-feed to the carbs even without the pump running. To solve that, disconnect both the power to the pump AND the vacuum line to the petcock.

I don't even have a cover.....

Mitch, Glad to hear of SUCCESS :D :D For the dashboard backlighting, I checked the schematics, the dashboard lighting gets its power from the same circuit/fuse as all the other running lights, so the dark dash problem isn't a fuse. So you either have a bunch of burned out bulbs, or there's a bad con...

Well Mitch, It looks like we've found the culprit. :D Much better to do logical troubleshooting than just throwing parts at a problem and hope that fixes it. Many people would have already put in a new "B" relay without fixing anything! :lol: But this culprit depends on proper mechanical actuation i...

Not necessary to remove heads to do valve seals. You can save the expense of head gaskets - they're pretty spendy. There's a couple ways to do this: A) You can get a length of small diameter rope and with the piston halfway down its travel feed a goodly amount of the rope into the cylinder, and then...

Mitch, Your findings indicate relay "B" is OK. If things are operating correctly there should be no voltage on the green/red wire when measuring to ground as that is the "ground" side of the relay coil. If you are reading voltage on that wire when pressing Start button, this means the ground is miss...

However when the motor is at operating temperature the starter will only click the solenoid and drains the voltage down in the battery visibly dimming the headlight. I have discovered the that if I short across solenoid B while pressing the starter switch it will start right up when at operating te...

Colorado just issued statewide Shelter-in-Place orders until Apr 11 to follow the orders issued by City of Denver on Monday. I've been telecommuting for two weeks now. At least I have a job where I can do that. I have much to be thankful for. I wonder if just riding the motorcycle around without sto...

Hi Mike, Welcome to the forum! You say "recently bought" but you haven't mentioned the history on this machine, has it been sitting without run for a long time? If so the smoke may be as simple as an accumulation of "funk" and "smedge" inside the exhaust and mufflers, it may take a little while to b...

For an album where important to play the tracks in order (like a live album, or a talking book) prepend a two digit track number (00 - 99) to the beginning of the filename before sorting the FAT on the thumb drive. The FATsorter would sort those tracks by number. I can see where this would work - ph...

Quite possibly a bad cap. A tiny crack or carbon track allowing the spark to snap where it's not supposed to and when lifted that "wrong" path is not so good.

A new set of caps not that expensive, and easy to change. I had to replace all four of them on my '80.

Thinking plugged gas cap, especially on a nearly full tank, you'll pump gas out of the tank and without a way for air to get in there to replace the gas you pumped out you build up a vacuum until the pump can't overcome it and pump more fuel. Thus you effectively "run out of gas". Loosen the gas cap...

I've got a '94 manual in PDF. It's 90 MB, too big to e-mail, but if you keep looking it's out there to download. Wish I could remember where I found it. Paper manual would be nice, but I have an old computer set up in a corner of the garage that serves me well. Not really much difference '93 thru 20...
