Top 20 1988 Suzuki GSX 400 XS Impulse Questions & Answers

It sounds like you have a bad vacuum leak. Check the carb mounting bols to make sure they are tight. Check all of the vacuum hoses for cracks and leaks. If this doesn't turn anything up, you can check for leaks around the carb mounting points by spraying carb cleaner around the base of the carb (If you spray the leak, the engine RPM will go crazy. - this can work on hoses that are hard to get to also)

Replace the clutch cable. Replace, or recharge and test, the battery, it should have about 12.5 volts when fully charged. Then you will most likely need to remove and clean the carbs. Use care in cleaning the jets, do not make the holes any bigger just get the crud out.

What do you mean by "Midway"? How old is this motorbike? What exactly did you do to clean the carburettor? Is it a new spark plug and a new, clean air filter? Did you empty the fuel tank to remove the fuel tap to clean the filter on the inside of the tap? Is it doing anything else? Things like - is it hard to start, has heavier exhaust smoke or it has a rough and uneven idle.

Behind the radiator on the left side. It is the device with cooling fins, even though the electronic parts are embedded in rubber paste.The location isn't ideal and sudden defects leave people stranded so what people do is relocate the regulator/rectifier to a cooler place. Perhaps to the air inlet, under the air filter. Follow the three, mostly, yellow cables that originate from the stator when you don't find it behind the radiator.

A broken timing chain is the most likely cause, the piston is hitting an open valve, or you have a dropped valve or a stuck valve. Another possibility is something jamming behind behind the side covers.The key would be how you discovered this? Driving along at 105 and the engine stopped, or ???https://www.google.com/search?q=2009+suzuki+boulevard+timing+chain+or+timing+belt....

The air/fuel mixture screw on a Suzuki VS800 Intruder is typically located on the carburetor. To adjust the air/fuel mixture, you'll need to locate the carburetor and look for a small screw that can be turned. Keep in mind that the exact location of the screw may vary slightly depending on the model year and specific carburetor version on your VS800 Intruder. Generally, it is located on the bottom or side of the carburetor. Here are the general steps to locate and adjust the air/fuel mixture screw: 1. Locate the Carburetor: The carburetor is usually positioned on the side or underside of the engine. Follow the intake manifold or air filter housing to find the carburetor. 2. Identify the Air/Fuel Screw: Look for a small screw on the carburetor. This screw is typically flat-headed and may be recessed. It is often located near the bottom of the carburetor. 3.Adjustment: With the engine running at idle, use a screwdriver to turn the air/fuel mixture screw. Turning it clockwise (in) usually leans out the mixture, while turning it counterclockwise (out) enriches the mixture. 4. Listen to the Engine: As you make adjustments, listen to the engine's sound. The goal is to find the point where the engine runs smoothly and the idle is stable. 5. Fine-Tune: Make small adjustments and give the engine a moment to respond before making further changes. It's a process of trial and error to find the optimal setting. 6. Check the Owner's Manual: Refer to your motorcycle's owner's manual for specific guidance on the location and adjustment of the air/fuel mixture screw. The manual will provide information tailored to your bike's make and model. If you're uncomfortable making these adjustments yourself or if you're unsure about the location of the screw, it's advisable to consult a professional mechanic or refer to the specific service manual for your Suzuki VS800 Intruder.

The crank case will be almost as hot as the oil flowing around the engine, lubricating the bearings.

f your 2005 Suzuki 250 is refusing to start even after replacing the kickstarter and battery, there could be several other potential issues to consider. Here are some troubleshooting steps to help you diagnose and resolve the problem:

1. Check the Fuel: Ensure that your motorcycle has an adequate supply of fuel in the tank. Sometimes, an empty tank or a clogged fuel filter can prevent the engine from starting.
2. Inspect the Spark Plug: A fouled or damaged spark plug can hinder ignition. Remove the spark plug, inspect it for fouling, and replace it if necessary. Also, check the spark plug wire for any damage or loose connections.
3. Examine the Air Filter: A dirty or clogged air filter can restrict airflow and affect engine performance. Inspect the air filter, and if it's dirty, clean or replace it.
4. Verify the Ignition System: Ensure that the ignition system is functioning correctly. Check for spark by removing the spark plug, grounding it against the engine, and cranking the engine while observing for a spark. If there's no spark, the ignition system may need attention.
5. Inspect the Carburetor: A malfunctioning carburetor can cause starting issues. Check for clogs, blockages, or a stuck float valve. Cleaning or rebuilding the carburetor may be necessary.
6. Verify the Fuel System: Ensure that fuel is reaching the carburetor. Check for fuel flow by disconnecting the fuel line at the carburetor and cranking the engine briefly. Fuel should flow from the line.
7. Compression Test: Low compression can also prevent the engine from starting. Perform a compression test to check the engine's compression levels. If compression is low, it may indicate internal engine problems that require professional attention.
8. Electrical Connections: Ensure that all electrical connections are secure, including those to the starter motor and solenoid. Loose or corroded connections can prevent the starter from engaging.
9. Safety Switches: Some motorcycles have safety switches like a kickstand switch or a clutch lever switch. Ensure that these switches are not preventing the bike from starting when they shouldn't be.
10. Professional Inspection: If you've checked all of the above and still can't identify the issue, it may be best to have a qualified motorcycle mechanic or technician inspect your bike. They have the expertise and tools to diagnose and fix more complex problems.

What EXACTLY is it doing to make you think it isn't getting fuel? This model does not have a separate fuel filter. The fuel tap on actual tank, (the petcock), has a gauze filter built into it inside the tank. These can sometimes clog up over time especially if it's had bad gas through it or it's been stood for a while. When was the last time the Carbs were serviced? This could be as simple as a dirty fuel jet or a dirty/worn needle. If your going to clean the gauze filter make absolutely sure the tank is empty BEFORE you remove any fuel lines or the petcock. I found that an old, stiff bristle toothbrush works well to clean the gauze.

limited info generic answer depending on area of leak cann be anything --rear seal --valve cover gaskets --oil filter --oil lines [if oil cooler --crack in block -need to wipe area and observe where leak is

try to refresh and start again
