Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.

Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.

Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

better check for the ignition coil for proper sparking or igniting of current in the comprssion chamber, check the ignition coil spark plug wire, check the spark plug, check for proper fuel supply in the flow system to Carbs, check for Ignition timing of the bike, or still you cant solve or still worried then dont worry better take the bike to nearest aurhorised Suzuki service centre for better assistance on this problem surely the problem will be solved.

SOURCE: my '86 suzuki savage won't rev up it just back fires

When I had my savage it backfired all the time. They are known for this. Make sure you fuel is not to lean. Just adjust the fuel. You should adjust that and put some sea foam in it or ethenol treatment since most of the gas is terrible these days. Running 91 octane will help. Also you will want to replace the muffler gasket too.
When you replace that it will smoke which is normal.
I sold mine but I know the bike pretty well from tearing it apart due to trying to fix it from not running properly. Let me know if you have any more issues.

1981 Suzuki GS 650 GL gas leaking out of tailpipe


Hi, Sammy80918 you need "FIVE" things in order for a cylinder to run properly:
1. FUEL: in order to validate your not getting fuel spray some starting fluid into the air cleaner and hit the starter button, if it fires up and runs for a few seconds then you know you have a fuel delivery issue. Multi carb banks should be bench "SYNC"
2. SPARK: remove the spark plug and with it connected to the spark plug cable ground the threads to something metal you should see a bluish white spark if not you have a faulty spark plug, spark plug cable, ignition coil, condenser, CKP, ECM, sensor or the wiring in between.
3. COMPRESSION: you must have at least 80-100 PSI for most bikes, multi-cylinder engines should be within 10-15% of each other if not perform a leak down test you may have a burnt or bent valve or hole in the piston or broken rings.
4. CAM TIMING: confirm your timing marks are aligned to see if the cam chain or adjuster are worn out and the chain has skipped a couple teeth.
5. IGNITION TIMING: on older bikes check to see if your points have not closed up, timing plate has not become loose and confirm with a timing light for proper retard and advance functions, on newer bikes where timing is controlled by an ECM and is nonadjustable check you CKP, TPS, MAP, O2, sensor or its counterpart for integrity.

I have a 1979 yamaha enduro 125cc i cant get it to start... i ran when i first got it and then it just died and i havn't been able to get it started... i changed the spark plugs cleaned the gas tank...


Did you squirt some gas in the cylinder to see if it would fire? Check the spark by laying the spark plug on the head, or holding it there with rubber handles, attached to the plug wire, see if you get a spark, if that checks out, you have spark, open up the air filter and peek in the carb, twist the throttle to see if gas comes shooting out. If not, squirt a little gas in the carb, try it, fire? check the fuel filter, pump, carbs could be gummed up. Did you get the jets clean? Run a wire through them to see if they are clear? Blow through them to check. Check it out.

1982 GS550LZ. starts right away but idle too fast. how do I track down a vacuum leak?


I have seen the rubber boots for the carbs crack on these and leak. Also check the rubber plugs for the synchronization ports. I spray wd-40 around and listen for speed changes. also spray around the carb butterfly shaft. Is you choke stuck on? does it slow down after its hot?
try to idle it down. Maybe your air screws need adjusting.

Why would a suzuki 4-wheeler not start. I have


Did you change the fuel filter? Is there a way to confirm that you're getting gasoline to the carburetor? If it fired once it should mean that you have spark to the plugs but there could also be a short in the kill switch circuitry that kills the ignition system. Pull a spark plug and put it in the spark plug wire socket, ground it against the motor and crank the engine and see if you're getting a good spark. Ensure that the air filter isn't dirty.

Engine wont fire up


Do you have fresh gas in the bike? Try changing the plugs with new ones and check for spark. You can do this by putting the new plugs on the plug wire and grounding it to the head on the engine crank the motor over you should see a bright blue spark. Check one plug at a time. No spark check the ignition wires and coils. As for the oily plugs it could be they are just fouled caused by either flooding the motor while trying to start, bad plugs, week coils, bad gas, poorly adjusted carb's. I would start with the plugs and work my way back to the carbs. Still fouling the plugs after all that start checking the engine, ie compression check ect.
