SOURCE: My Suzuki VL1500 cranks but really struggles to start!

When was the last time the valves were adjusted? Valve adjustment affects more than compression but vacuum as well and should be checked... A lot of rider never check it until they have a problem like this, and it gets worse when it is colder outside.

SOURCE: my suzuki gsxr 600 srad started to over heat.

One, or more, of the three necessary ingrediants for combustion are missing: fuel, compression, and a spark (at the right time).
You said that it started to overheat. Find out why. Then, check the engine's compression. You need at least 140 psi of compression, in every cylinder, for the engine to start and run. Low compression indicates either the need for a valve adjustment - or serious engine repairs.

It is a very good chance your Kill switch is on, find it and turn it off. You need a manual, but I haven't got a freebie available. Just google it and there will be plenty for sale, but if you hunt hard enough you can generally find a freebie.

Suzuki gsxr 750 slingshot cranks but wont start.


For a motorcycle engine to run you need compression, ignition (spark) and fuel. Quite often with a bike like a Suzuki if the plugs get even a little wet but otherwise look like great plugs, the motorcycle will not start. So, new plugs are a good place to start, however if you put in new plugs and try to start a few times and have fuel but no spark the new plugs may become unable to start also.

FIRST check to see it you have spark at the spark plugs, then remove the plugs and either do a compression test with a gauge OR put a finger over the plug hole and turn it over and if you have adequate compression the engine will blow your finger off of the hole when it comes up on the compression stroke.

If you have a carburetted bike you can check for fuel by taking off the air filter and operating the throttle a few times full open in which case the accelerator pump should eject a spray of fuel into the carburetor throat. With Carb or Fuel Injection you could also spray some fuel into the carb throat or the induction module throat while turning the engine over with spark at the plugs. If you have spark and compression but no fuel th eengine will fire when you spray the fuel into it.

My suzuki raider 125 model 2010 won't start even in kick starter


check if a spark is coming when you turn the engine and continue from there, if yes then fuel is not getting in the engine. If no start by changing the spark plug and move from there.

If it turns, then the battery is OK. Either spark plugs are not firing in proper order (wrong firing order), no power to spark plugs, or no fuel because of fuel restrictions (dirty fuel filter). Inspect the air filter to ascertain its not clogged air. If you smell gas, then you saturated the spark plugs, which is why it refuses to run.
Let it sit for half hour to let spark plugs dry. Inspect to ascertain its not dirty spark plugs, which will also prevent engine from running. After ascertaining its proper firing order, spark plugs are clean, and there's power to distributor cap, ascertain there's fuel in fuel lines by squirting half second (short squirt) of starting fluid into air filter. Close the air filter housing to trap flammable starting fluid gas. Turn engine without giving throttle. Let starting fluid be ignited by spark plugs. If it won't start, then spark plugs are not firing to ignite starting fluid gas. If it starts briefly, but won't run when you give throttle, but catches when a 2nd person squirts more starting fluid into air filter just before engine stalls, then its a fuel restriction issue or no fuel in fuel lines.

2008 suzuki jimny wont start Was running ok then


sure , they all ran like new, when new. or yesterday.
but not now. that means it BUSTED.

so check for spark.
if not spark then fix that.
modern cars have EFI, and all EFI cut fuel if the cars ECU brain
even thinks for a moment there is no spark (it can see it?
so spark is 1st. (if engine is good,)
ever give the car a full 60k mile tuneup, (100km)
if not why not?

Cannot get my bike to start


Remove rubber connection from carby inlet (between carby and air filter) enough to get a piece of thin card to cover inlet to carby. Turn motor over with throttle half open for a few seconds. Remove card and see if any fuel is on the card. If there is, repeat process (fresh card) without throttle, fuel should still appear. If there is no fuel present, you have a fuel blockage. If engine still not starting with fuel present, you have an electrical problem, check for spark by resting attached plug to engine metal and turning engine over.

Suzuki bandit 1996 will not start


If you have spark and still the bike is not starting ( and the timing on the spark is correct) make sure you got fuel flowing to the engine, if fuel is getting there and still the engine doesn't start, check the cylinder head and pistons and make sure you got compression. These are the problems that can cause a bike not starting. Hope it helps

Bike wont start turn over till batery dies. where


It will have a fuel filter in the fuel line (should be easy to find) but does not have a fuel pump. Firstly i would check you have spark on all cylinders as this is the most likely thing to be going wrong. Once you are sure you have spark you can start trouble shooting fuel and air delivery problems.
To check for spark remove a sparkplug, insert it back into its HT lead. Place the threads of the sparkplug on the engine block and crank the engine. A strong blue spark should be visible.

Engine wont start...


since have change new battery, will the motor turn over? if the engine turn over or crank, check if you have sparks, by pulling the plug out and ground it to the metal to the bike and turn the motor over and see if you getting spark, double check if you are getting fuel, two items to make the engine run, sparks and fuel. if the stater dont make any sound when you press the start button it may be faulty serenoid to the starter, check starter and starter switch. you can get a light tester and test positve and negative contact to your serenoid/starter by hold or pressing start button to see if you get power to the starter. hope that help some
