XV1100 Starter does not engage when trinig to start engin


sorry didn't actually see the post before my first comment, if it is only when the bike is warm or hot but not over heated I would suspect the same thing, faulty starter. "replace or rebuild"

I have to kick start my 2000 ducati st4 bought a new batt fully charged it thats not the prob although its sounds and acts like it now it just makes a ticking sound as if the batt was dead pls help


Check the terminals are clean and tight on the new battery
depending on where the ticking sound is coming from it could be the solenoid or the starter motor.
use a multi meter to check if power is getting to the starter motor when the buttons depressed.
If it gets power, could mean the starter needs brushes, if it doesnt get power more likely the solenoid is bad

Realistically, diagnosing the problem behind a bike that won't start, can be a frustrating experience, as there are many potential problems that can create the same symptoms. Here are a couple of guidelines to help determine the root of a "labored" starting problem, and by "labored", we mean that the starter motor kicks in and attemps to turn the engine over, but either can't get it over the "hump", or does so with a lot more effort than usual.

If your battery is over two years old, and you CONSISTENTLY have a labored start, then the first suspect will be the battery.

If she starts cold with no problems, but CONSISTENTLY has labored starting while hot, then the charging system should be checked. A grounding rectifier can actually discharge your battery while you ride. The battery can somewhat recover while sitting, so it may well start the bike while its cold, but then not be able to start it after only a few miles of riding.

If everything on the bike seems to be in perfect order, and you OCCASIONALLY have a labored start, or no-start, for no apparent reason, and with no perceived pattern, then very likely, the rear decomp cam is loose. A good test for this is to place the bike in second or third gear when it won't crank, and push it backwards a few inches while in gear, then try again. If it starts then, you definately have a loose rear cam. Pushing the bike backwards while in gear moves the rear piston back off its compression stroke enough to give the system a running start at it when you push the button. This will only happen when the rear cylinder stops on its compression stroke. Therefore, it seems impossible to predict when it won't start. Might be cold, might be hot, might only happen once today, but maybe three times tomorrow...This occasional no-start is the prime indicator that the problem lies with the rear decomp cam. (If the front cam were out of adjustment, it would NEVER start properly, as both cams would then be off their specs.)

I have to kickstart my bike for about 10 20 min elecric start just keeps going does not start the engine please how do i fix this


If you are saying the starter just spins and doesnt start the engine then your starter bendits has gone bad and is not kicking out to meet the fly wheel. You while have to remove the starter and have it repaired or replaced.

2004 1200 r oil light came on killed the starter fulll of oil?


The oil light should come on when you turn the key on, then go out when the engine starts. It is NOT an oil level light, it shows PRESSURE.

Your "click" is a bad/corroded connection on the starter terminals , battery terminals, low battery, bad wires, or a defective solenoid. Charge the battery. Disconnect the negative battery cable, then the positive. Remove the nuts holding the wires to the starter, clean all connections at the starter, frame and battery with a wire brush. Get them CLEAN!! Make sure the big cables are in good shape. If that doesn't fix it, you will need a solenoid. Maybe a starter and/or relay too.
