You need to fix the fueling first - without fuel it won't run!
Your other problem sounds like an air leak - either the manifold or the carb. Check by spraying WD-40 or CRC at the manifold and carb join while the bike is running - if the revs change (either up or down) you have a leak.

How do i test to see if the spark plugs are fireing


Hi Anonymous, remove spark plug wires off of plugs, leave spark plugs in heads. Use a 3rd known good spark plug to check for spark.
Insert 3rd spark plug into any spark plug wire, ground the threads on bare metal like the edge a cylinder fin. Turn ignition switch on and make sure run/stop switch is in run position and the bike is in nuetral. Hit the starter button and watch for spark. Good luck

Cylinder firing not


Hi, Anonymous 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.
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 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 it's counterpart for integrity.

Check to make sure the battery is fully charged and that the fuses are all good. If you push the starter button and the solenoid clicks, the button is good. Take a wire and jump the two posts on the solenoid or touch the two cables together, if your starter works, then you need a new solenoid. If you hold the starter button and tap on the starter with a plastic hammer and the starter works you need new starter brushes. Anything else wrong with the starter and you need to replace the starter assembly , unless the manufacturer sells replacement parts so you can repair the starter. most manufacturers only sell replacement starter brushes but no other internal starter parts.

Started, died will not stay started unless starter button is held


Check for spark and fuel. The spark should be blueish-white and consistently flashing. If the ark is dull-orange and/or inconsistent then there is a problem. the fuel should flow freely from the pet-****, through the needle and seat, and past the primary and secondary jets. There are other things that can cause this problem, check the intake manifold gasket, spark plug, wire, water in the gas, and so on. well good luck.

Starter probs


Do you have spark? Be sure the kill switch is off. Be sure that bike is in neutral and the side stand is up. Check the fuses. Next check the wiring connections, color to color and tight connections? Did the starter button get unplugged? Do the button wires show continuity when the button is pressed?

Let me know what you find. Please rate this answer. Thanks!

Hi!

Nahh, i dont think the problem is any wire, the problem is more lite the sparking plug or the carburettors. Is is after all a 1990 model, i dont know when you replaced the sparking plugs last time, but im sure you never cleaned the carburettors.

Try first to replace the sparking plugs,thats the easy job, if that dosent make is start easyer then you have to take the carburattors down and clean them, and thats the hard job.

Good luck
