hi

fuel capacity -9.5litres (2.5gallons us)
reserve capacity-1.5litres(0.4gallons US)

you could have damaged it, but if you were just at idle, you may be ok. If you were out running hard, maybe a bit of damage.
Either way, drain the oil and change the filter. Then check the waste oil for metal particles...
that will be a good indicator of damage.
Also after you add new oil, run it and check for excess noise.
Thirdly, watch exhaust for excess smoke..
You may just luck out here...

yes bigger gear on back will give that low end power

your cars needs cleaning and you need a new spark plug.

stuck floats ..remove carbs strip and clean rebuild with new seal kit

Make sure the carb is thoroughly cleaned, all jets not just main. The half choke is compensating for the slow circuit jet. Check your air/fuel mixture. Also, check the air and fuel filter. If all checks out fine and you still encounter the problem, could be : bad gas, wrong spark plug heat range, or most likely the diaphragm for the top of the carb.

may need a new starter if it cranks slow when hot

4 ounces of oil per gallon of fuel.

On the right side of you motor, there will be a sight glass.
You will have to crouch very low, and possibly lay on the ground to see it.
The sight glass is in the right side cover towards the back and at the bottom.

If your oil is in need of changing and has turned dark in color(black). The sight glass isn't so visible when the oil is black.

Thats how you check the oil level with the bike off the kicksatnd and you holding it staight up, while looking at the sight glass.

I have a 2003 XR 400 that I bought in 2005 nearly new (seller was more of an MX guy than trail guy). Thing was HARD to start no matter the conditions; hot day or cold day, sea level or 7000', dry or wet. Once I tired myself out completely and got it running, it would restart ok, but still always a challenge. After months of gritting it out, I followed the advice of everyone online. I bought a pumper carb. Don't even screw around with getting just the right jets, or all the other stuff you've already done. You bolt on the carburetor that the bike should have shipped with and you'll be one or two kicks from a nice run/idle/ride. I ride literally from sea level to 5000' with zero issues. I ride at 7000' no issues. Seriously, It was the best ~$350 I ever spent.

On the front right corner of the motor is a round cover held on by two bolts (one short ,one long). The oil filter and spring are under the cover. Be sure to only use JASO MA motorcycle oil . 0w-40 Amsoil synthetic oil works great in your model.

Contact you local honda dealership ,they will tell you ./

Half the time the problem is the cable due to lack of lubrication. Try adding liquid graphite (lock Eze) into the cable. Check for kinks along the length of the cable and bad routing of the cable. The other half of the time the problem is very dirty oil in the gearbox. Try an oil change.

The Power Steering has failed. There has been a factory recall for a suddenly failing electrical steering shaft, that could cause the rider to loose control. This does not have to be your problem but anyhow either the electronics or the pump failed. Error codes or messages usually have to be erased by a simple reset procedure or disconnecting a plug, after repairs are done.

Question edited for clarity, but no idea what you mean by - "What do I need to do to get the gay? The clutching gauge in again?" You issue is probably that all the clutch plates are glued together. Leaving a bike for 21 years will do that. https://www.google.com/search?q=1985+Honda+Gold+Wing+1200+stuck+clutch ..

Check the wiring, especially the engine earth lead.

On the bottom of your speedometer on the left side there is 2 buttons press the far left one for a couple of seconds and the light should go on

Question edited for clarity. The RC26 has a few modifications, but nothing that should alter the wiring.

1986-1987 - VFR700F / VFR700F2 (RC26)

The "Tariff Buster"[ 700cc VFR700F was almost identical to the 750cc version, with minor changes to graphics (no 750 on the lower fairing), shorter stroke, different cams, and altered ignition timing. Otherwise the VFR700F2 was mechanically the same as the standard F, but had an upgraded rear shock and fork internals alongside square gauges.
