head marking

Is there a mark of some kind that indicates the left head from the right? Does it make a difference if the heads are not put back on as they came off?

gl1200 heads

Recently replaced the head gaskets on my GL1200 due to oil leaking into coolant. Solved that problem beautifully, but, now I have a vibration and slapping/rattle when the engine is warm at around 3000 rpm. My question is - are the heads interchangerable left side/ right side? I'm not sure I put them...

Re: GL1200 Aspencade digital display acting up

Same thing happened to me a while back. I found a used unit (broken casing, but LCD part okay) on e-bay and popped it in the original housing. Worked perfectly since.

radiator flush

With the radiator OUT of the bike, what would be the best method to make sure the radiator is 100% clean? What kind of cleaning solution (I imagine soaking for a day or two) would best ensure a squeaky clean radiator?

rattling noise at high RPM

I have a rattling noise that occurs when the engine RPM goes above 3000. It's much less noticeable when the engine is cold. Matter of fact, it runs like a dream below 3000. I don't think it is piston slap, although I'm really not sure. It's more noticeable when I crank the throttle hard. Any thoughts?

86 reed valves

Recently took apart the carbs on my 86 Aspencade and cleaned everything, including taking apart and reassembling the reed valves. Then read in Clymer manual that this is a no-no. Now the bike misses noticeably but seems to smooth out at higher rpms. Could this be part of the problem? Reed valves see...

Engine Vibration

I know this is vague, but I have an irritating (and worrisome) vibration coming from the engine, getting progressively worse. I can feel it through the handlebars, footpeg, seat, etc. It is definitely the engine, not wheel bearings. Could faulty carburetion be a possible cause? Any thoughts would he...

gl1200 camshaft

Are the camshafts on the GL1200 interchangeable left and right? They (the replacements) both look identical. I'm using cams from an 87 bike for use in my 85 engine.

86 GL1200 turn signal

Trouble with turn signals. Is there a flasher unit somewhere in the wiring. If so, where is it? Running lights work, but no turn signal

86 Aspencade turn signals

Both turn signals were working fine, then, suddenly, both stopped abruptly. Running lights both come on when ignition is on, but NO turn signal. Relay (the one under the coils) is okay I believe. How would I test the switch? Or am I overlooking something elsewhere in the circuit?

85 GL1200 Oil in coolant

I'm getting a relatively small amount of oil in the overflow container. No coolant or oil burning out of exhaust as far as I can tell. I know I might have a head gasket problem, but I want to know if there are other areas where oil can get into the cooling system. I'd like to avoid new head gaskets ...

86 GL1200A electrical problem

Bike is charging nominally at around 13 volts (no higher), and all the lights (headlight, brake, etc.) flicker when engine is running. Digital dash will cut in and out at low RPM. Also, on occasion, when I depress the starter button, I get nothing to starter and dash lights (oil, neutral) cut out. S...
