If you turn the bike on and all the lights are bright the battery should turn over the bike.If you push the starter button and the solenoid clicks the button is good. If you jump the posts on the solenoid and the starter works the solenoid contacts are burnt replace the solenoid ( the starter is good). If you hold the starter button and tap on the starter with a plastic hammer and the starter works, you need starter brushes. If you take the starter apart and don't have continuity (using a voltmeter) between every other contact on armature it is bad replace the starter with new or rebuilt.

no tricks it is very difficult and very easy to break the cases just take your time with it and work them apart

2008 Honda CB... | Answered on May 07, 2009


I've never heard of this being a problem, especially if the bike isn't total junk. Keep us posted on what you find, will you? I'm guessing it's gunk in the carb body itself, not something on the outside, but I'd like to hear where the problem truly lies. If things are that stiff with the throttle, I'd probably double check to make sure the slides move freely...stuff like that. I'd probably do a good carb cleaning anyhow if it were me. If you're reluctant to do that, at least plan on using some Seafoam for a while to help make sure your passages in the carbs are clear. The bowls being clean is definitely a good thing, but you still need to be concerned about your floats, float needles, and slides being sticky even if everything looks good. Doesn't take much gas to make things gummy. Just remember that if you aren't familiar with cleaning carbs, carb cleaner and rubber parts DON'T mix well. You need to be sure to follow your manual closely if you do decide to clean your carbs. If you have questions about this, post them before you start...it can really save you headaches later on. One thing to keep in mind when it comes to older cables is that they sometimes can seem like they're okay when off the bike, you can check them and they'll seem like they move alright, but as soon as you get them put on the bike with the bends everything, they'll bind enough to cause a stiff throttle. Just thought I'd mention that in case things still seem stiff even after you take care of the carb work.

Hi, Dagle if your bike has been sitting idle for weeks, months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will not idle unless the choke is full on and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging the battery remove the leads and let it sit for a couple of hours then check the battery voltage with a voltmeter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank if it rusty there is a cheap and easy fix. https://www.youtube.com/watch?v=fUYr_7SwGms
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil-soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a "CARB DIP" or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and craks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

Hi, Justin_wulbe before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries.
1. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
To do this with a meter: black lead to battery ground, red lead to each pin on the plug, start with the voltage scale higher than 12vdc and move voltage scale down in steps for each pin. Any voltage is a bad regulator.
3. On the other part of the disconnected regulator plug. Set the multimeter for Ohms x1 scale and measure for resistance across the pins of the stator. You should read something around 0.1 to 0.2 ohms for a 32 amp system.
4. Then check for continuity between each pin on the plug and frame/engine ground. The meter needle should not move (infinite resistance)(digitals will show infinite resistance) if the meter needle does move (indicating continuity)(digitals will show some resistance), recheck very carefully. If the meter still shows continuity to ground the stator is shorted (bad).
5. Set the meter to read A/C volts higher than 30 volts (the scale setting for voltage should always be higher than the highest voltage you expect or you may fry the meter). Start the bike, and measure from one pin to the other on the plug (DO NOT cross the multimeter probes! - touch them to each other). You should read roughly 16-20 vac per 1,000 rpm.
6. If the battery was good under load test, if the stator is NOT shorted to ground, and the stator is putting out A/C voltage, then the regulator is bad (most likely even if passed step 2)
