Are you sure it's gasoline? If you have gasoline seeping from under your front cylinder, you do have problems. If it's gasoline, it's probably coming from your carb and dripping down to right behind your front tappet block making it look like it's coming from the front cylinder.

The next time you park the bike. Take a paper towel or a piece of newspaper and put it under the carb. Let it set for a while and come back to see if you see any "drips" on the paper.

Now if it is your carb, the most likely place for it to leak is the accelerator pump diaphragm. If the original diaphragm is still in the carb since '94, it's probably got a hole in it. At any rate, it's time to have your carb completely gone though. This is a job for an experience mechanic. If you wish to attempt it yourself, you need to purchase a service manual because it is far too extensive for me to type out here. And, a picture is worth a thousand words in this case.

Good Luck

My 1996 road king will crank but not fire at times. getting gas and spark.

A spark plug may fire when out of the cylinder, but not fire properly when under compression. Replace the plugs and get your coils checked out for correct resistance and operation. You will find the correct readings in your manual.

How to remove harley road king gas tank fuel 2005 model

I have a 2008 Road King Classic (and have had the tank off), so maybe they're similar.
Disconnect the negative lead of the battery.

My dash has a screw under the nose of the seat (which must be removed) and one in the front.
lift dash and unplug harness.

If you have a gas gauge in the left hand gas cap, underneath tank unplug it's connector.

The fuel line has a quick disconnect. Pull fitting, and line unplugs.
There is a check valve inside to keep gas from leaking, but it's a good idea to have a catch cup, just in case some residual fuel flows out.

From there, I have a bolt on each side of the front of the tank, one in the center rear, then lift it off.

I need to bleed my rear brake but I can not locate where to fill the rear brake reservoir on my 1994 FLHTC.

On most FLHTC bikes, the reservoir is behind the side panel above the master cylinder and has a hose that runs down to the rear brake master cylinder.

Brake light will not turn off 2010 road king

First, if the bike is still under warranty, I'd take it back to the dealer. But, you can try loosening the bolts that hold the front brake master cylinder onto the handlebars and then slide it as close to the right handlebar switch housing as possible. If this doesn't put the light out, you may have a bad switch. It will have to be soldered in.

The wind affects the front brake on my harley 2006 road king. At speeds 70 and above, when I set the cruise, the wind causes the hand braketo move and disengage the cruise. there is a little slack on...

Loosen the two bolts that holds the front brake master cylinder on the handlebars. Slide the master cylinder as close to the right handlebar switch housing as possible and retighten the bolts. If that doesn't work, you may have to purchase a new lever and pivot pin.

Good luck
