Bike wont start

I've been plagued with unable to start my bike. I've checked the carburetor which looked good. The spark plugs look pretty black which I replaced, but still can start. I checked the new plugs after trying to start and can smell gas on the plugs but still no starting.

The bike wants to start, but it just wont start up.

Oil replaced. Gas removed and add a bit of gas to see if it was just bad gas. Still same problem.

To make matters worse, I thought maybe the play in my clutch lever was part of the problem and thought I could tighten the cable by turning the larger adjusting nut, but that just broke the cable's adjusting nut right at the larger nut :(

Any ideas what's going on?

Killed the battery trying to start. Now I'm charging the battery up. Once it's back up to full power I'll try holding the clutch and see if that changes anything, but I am at a loss as to what is keeping the bike from starting up.

I hear the bike pushing and pumping, but it stops short of combustion i think.

I did notice one other observation by mistake. I forgot to place the cables back on my spark plugs but the bike is attempting to start with the same inability to ignite.

I'm getting the feeling the new spark plugs aren't firing. Could this be a bad battery?

I'm starting to think my problem is the battery. Is 13.3 Volts enough to start the engine?

Maybe the leads going to the spark plug? Not sure how to use my voltmeter to confirm.

I would try testing the plugs grounded out on the head to see what kind of spark you are getting . Another thought is getting the battery tested to see if it has a dead cell .

I think the source is the ignition coil. My brother and I pulled the plugs to see any sparks and got nothing. We were trying our voltmeter and noticed no signs of life through the cables.

I'm going to be pulling the ignition coil so I can do better testing, but it looks to be impacting all spark plugs.

Background information: before this all stopped my bike, which was sitting for some time, was sputtering when I would open up the throttle for some time and we thought it was bad gas or a gunked up carburetor.

So the poor performance may have been the inconsistency of the leads to my sparkplugs.

To be continued...

I would suggest getting your hands on a manual and running through the testing/diagnostic steps for ignition/spark issues. Could be bad coils, could be a bad CDI, bad wires, all of the above or some combination. I just had to do coils myself.

You note the bike was sitting for some time (how long? was it stored properly with Stabil in the fuel?) If it wasn't stored correctly you could also have issues with varnish in the carbs from old gas.... which wont affect spark but will affect how the bike runs with spark; if it runs at all. You may very well sort out your no spark issue only to find the bike still runs like crap from sitting with old gas in it. Depending on how long it sat you may want to remove and clean the carbs too.

I originally thought it was gas too, because it was sitting for some time. But I removed the old gas after throwing seafom in it for a bit.

Emptied the gas and opened the carb up and found it to be pretty clean. I've taken the rear coil off and need to test the lines. Both coils are not sending sparks.

My problem is I don't know how to use my volt meter to determine the extent of the power issue. My brother is a mechanic and I'm hoping he can help me determine how to verify if the problem is the coils/leads to the spark plugs. If I'm lucky, that's all that needs to be done.

Remove the coils and get this thing running. The bike has been ran very little in the past year because the radiator sensor went and I also had to replace the water pump gasket. By time I replaced all that my bike was sputtering when I would hit the throttle. Again, thought that was old gas, but now I realize it was poor electrical giving me crappy spark ignition.

*crossing fingers* I hope I've found the final solution and this bike will be ride ready again. It's just sad that after I'm done doing this, I'll be selling the bike to make way for a my first child. But this is a good trade off.
