Sounds like carb problems. You will need to dismantel them and clean and adjust them.

Put a full can 16 oz of Seafoam in the gas tank full of fuel and ride it. It may be a dirty carb. If it has a fuel filter replace it also check the air filter.

    Fuel injection. Gotcha. Still if it has a fuel filter change it. Seafoam works good in fuel injection. I see that you tried that. it may have to go to a mechanic.



    Good Luck.

Rough idling when warm heritage


Sounds like it is sucking in air from somewhere. Check between carbs or other gaskets. Good Luck

Burning gas


oxygen sensor faulty, engine out of time, crank or camshaft sensor.

Bad Gas Mileage Causes:
  • Having bad oxygen sensors and air filters can reduce your gas mileage by up to 20%. The oxygen sensors help keep the proper mixture of air and fuel, and having this off balance can be inefficient. The air filters can get clogged and simply need to be unclogged to fix the problem. Air filters need to be cleaned so that the engine can work at its peak performance.
  • Your spark plugs are responsible for sparking combustion in your engine. If they misfire, or are working poorly, this can effect your gas mileage in a negative way.
  • Having bad fuel injectors can cause bad mileage. This is because the fuel injectors are responsible for putting fuel into the engine. If there is a leak of some sort, then less fuel will make it to the engine, and then in turn make it run less efficiently.
  • Having your air conditioner on causes a lot of gas to be wasted in powering the system. If you can, turn off the air conditioner, and ride with your windows open. At higher speed, close the windows though to reduce drag.
  • A common cause of bad mileage is your own driving habits. If you are an aggressive driver, likely you accelerate to quickly. This causes more fuel to be used, and will use up more gas than you need. Same goes for revving your engine. It may sound cool, but it uses up gas for going nowhere.
  • Many people waste gas by idling. Idling is when you have your engine on, but you are parked and not moving. Common places where this occurs is when you are trying to warm up your car in the winter, or while you are waiting to pick someone up. Your car really doesn't need more than 30 seconds to warm up the engine. When it comes to waiting for someone, turn your car off or put it into neutral. Since you aren't moving, you might as well save gas and the environment.
  • The type of motor oil that you are using can also affect your gas mileage up to 12%. You want to use motor oils that are high in reducing friction. Either use asynthetic oil or the oil that the car's manual recommends.
  • The more revolutions per minute you make your engine do, the more gas you will use. The easy way to combat this is to just drive slower. Driving the speed limit of 55 miles per hour is much more fuel efficient than driving at 60, 65, 70, etc miles per hour.

My 2006 streetbob keeps miss firing when idleing and when I ride it changed plugs and wires and got a hd mechanic to analize it on a computer and still nothing. I took it to another shop and still they...


Don't let your bike just sit there idling. The choke circuit is needed for initial start-up.
If you leave the choke on, when it warms up a little, the choke circuit is putting to much fuel into the cylinders. The added fuel doesn't get fully ignited and just sits in the exhaust pipes. When you get on the throttle, the unburned fuel in the pipes gets ignited and explodes, causing the backfire.
Use the choke to get the bike running. You should be able to start riding after less than a 1/2 minute. And during that time the oil is well circulated to lube all internal parts.
As you're ridding, slowly turn the choke off in increments. As soon as the bike will idle on it's own, the choke should be off to prevent an over rich mixture and foul the plugs.
Plus you're well into your ride and have saved a little on gas mileage.

Is 60,000km's alot for a 2003 v-rod?


Well, let's look at it this way. The bike is six years old so that's 10,000km's a year. Here in the states, that would be 6,200 miles per year which is considered high mileage on a motorcycle here. Most riders here are recreational riders rather than transportation riders and their mileages usually is about 2,500 miles per year.

More importantly than the total number of miles on the machine is the quality of the upkeep on the bike. Has the oil been changed on a regular basis and has the little things that go wrong with a daily ridden bike been repaired. I've seen bike with that much mileage on them in great shape but bikes with much less mileage in terrible shape.

Next, it the bike appropiately priced having that much mileage on it? You should be able to go to a bank and find out what the value of the bike is. Make sure you ask them about the mileage factor.

Good Luck and Ride Carefully

Way too rich (pollution, horrible gas mileage and shortening the life of the engine by washing down the oil)...

S2r problems


A few things to check/do * make sure there is no animals living in the airbox make sure your idle is at or around 1200rpm +- 100rpm * start looking for someone in your area that can do a good fuel injection set-up [/list] what do the spark plugs look like? is sounds rich the clicking and hissing is the fuel injectors and the air bypass , when the air bypass screws are out a bunch it can get loud. screwing these in will richen the bike and lower the idle. I would bet that they have been used to get the idle up and that is why they are loud. The techtron will work fine as you have it. I doubt that it will help what you have described. I would do the easy things yourself (new plugs and check air filter) and find someone to set up the fuel injection properly. plan on around 1-2 hours of shop time to set it up. They should also be able to read any codes if there is something wrong. good luck

Bike trouble


Yes! You will open those things up, and they will probably look pretty clean, but the problem with your carbs is in the Idle circuit - too small for you to see into. If you do a search of carb cleaning or related topics, you'll see that alot of folks with cab problems try to clean their carbs ... only to have to open them up again due to improper cleaning (They are difficult to clean properly, require alot of patience) So, I would suggest that you have them cleaned professionally, or at least buy good carb dip to get them really clean. Spray cans of carb cleaner are worthless. Might as well wash em with dish soap.
