    I bought the bike new , first time this happened the dealer worked on the bike and said that the carbs were gumed up they cleaned .them.again still keeping the additive Stabil in the gas tank , the dealer is saying now that the gas is older than 30 days old "gas is junk" I though if you put stabil in the gas you could store the bike over the winter . Not so by them 30 days gas is no good and carbs will gum up.The bike will not start now. The dealer says the needle valves in this bike are so small it dosent take much to gum them up.I just have a hard time beleiving that all royal star oweners are dealing with this problem also.Why is this happening. Bike only has 200 miles on it , cant ride it if it wont run,,

    very confused please help if you can...

    The dealer is lying to you. If your carbs are really "gumming up" there are a couple things you can try. First, install an inline fuel filter. I suggest one of the small glass ones so you can see if it is picking up anything from your tank. I think you will find that it is not. The next think you can try is an additive in the gas, Stabil or Gumout or STP fuel treatment. I think you will find those do nothing either, indicating your problem lies somewhere other than inside the gas tank.

    What indication do you have that the carbs are gumming up? Have you seen the gum? What color is it? Where exactly is it appearing? Needles, jets, intake?

If & when you do get it running again, does the bike have a petcock at the gas tank? if it does, when the bike is running before you are about to park it for 2 weeks, turn the petcock off and let the bike die on its own (from fuel starvation). this will ensure there is (almost) no gas in the carb to cause any gumming. you can drain the little bit that is left with the carb bowl drain screw. then when you're ready to ride again, simply turn the petcock on, wait a few seconds for the carb bowl to fill, then hit the start button.

I have had my 06 royal star sense she was new i never use stabil or any other additive in the new jersey winter when i put it up. i do however run all the fuel from the carbs by closing the fuel valve and running it till the bike konks out. this ensures that no fuel is left in the carbs to gum it up in the first place. my first ride of each season commonly gets rid of the old gas and my first fill up after that is premium high test. she runs like a top long and strong. 16kmiles and counting.

I have a 2007 Royal Star Tour Deluxe and have never had the problem you state. I have 20K+ on the bike and it has gone for several weeks and over a month in the winter without being ridden. I am changing the spark plugs today even though they could really stay in the bike. I use mid-grade gas and every 1000 miles or so I put a half bottle of Lucas gas treatment in it. I use synthetic motor oil, not so-called motorcycle oil which is a bad joke the oil companies play on us. I also add a bottle of STP oil treatment with every change. In the winter I try to remember to start the bike every two weeks or so and let it run for 10 minutes. Never have used Stabil. The bike runs like a top and has never needed service. I wonder if you are being duped. I think the guy who suggested that you look at the gummy parts is right on. Unless your bike is real different, it has a carburator, not injector ports.

How do I check the check engine light indicator on my 2005 yamaha royal star tour deluxe!!!!

Often a code will show up after involved work like you accomplished. I would reset it, if it doesn't come on again don't worry about it. Here's the procedure, read this thoroughly before doing it please; 1. Disconnect the positive wire off the battery. 2. Take the positive WIRE and ground it to the frame (use a jumper or screwdriver if necessary) Hold it there for about 30 seconds. This will erase the code and flash memory. 3. Hook the wire back onto the battery and start the bike. Expect a little rough idle while the computer relearns it's parameters, Easy. Of course follow all safety precautions about playing with batteries, that warning should keep all the attorneys in the world happy.

If the bike sat through winter...carbs may be gummed up on idle circuit....could try a product like Seafoam ...add to for awhile to get the treated gas in carbs....then let it sit a day and retry.
You're certain its actually firing on all 4 plug wires?

Where do you check the oil level on a 2008 royal star touring deluxe

There's a glass window on the right side of the crankcase marked for high (max) and low (min) levels. Get on hands and knees, have somebody hold the bike upright, and look under the front crankcase cover directly beside the right operator's footrest; you'll probably need a flashlight to read it.

Gas pours out of bike when I turn the key

Sounds like one really crappy and dumb dealer if you ask me. Yes, they usually have gas in the tank on the showroom floor. Yes, varnish can build up while on the floor. The good thing is that cleaning a carb is not very hard.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

Bike wont start and fuel comes pouring out.

Hi, Please don't shoot the messenger, I have a royal star and this has happened to me more than once. The carbs are gummed up from sitting and you have to take them apart and clean them. The fuel pump is overfilling them because the float needles are stuck and the main jets are gummed up. The fuel is coming out the overflow hose. Sorry!
