Starting Problems

Postby lgsparks1 » Fri Sep 28, 2012 9:45 am



Ok here we go. I have been having a starting problem now for a couple of months. If I ride my bike daily or at least every other day no starting problem. If it sits for 3 days or more or more when I hit the start button the starter just clunks. It will finally start but only after several hits on the start button. I have thoroughly been through the starter and had it tested, it is fine. Battery is good and also replaced starter relay. Ground good. Left it for 3 days on side stand and 3 days on center stand with same results. Tried center stand because I thought left side cylinders might be filling with fuel or oil and hydrolocking. Anyone run into anything similar?

Put a voltmeter across the battery terminals and measure the voltage before you start, and then when you press the starter button and get the CLUNK.

When it does finally crank,does it crank normal or really slow.?
A slow crank would lead to a poor amp capacity in the battery.Load test it.
A normal crank speed then would lead to a bad start solenoid(burnt contacts inside).Hold the start button down and jump the solenoid.
You could also measure the volts on the starter at the moment it goes clunk to see if it's still getting volts and then move to the battery to see if it's there(while holding the start button down)
Also a corroded ground from the battery is suspect here too.

Ground is good and clean. When engines does finally start it fires right up.

Let's do a easy test.Get a test probe.Attach it to the engine and remove the battery cover.Probe the battery post of the starter solenoid for a bright light.Hold the probe on the starter post and hit the start button.Hopefully it will just clunk like before.If the light only blinks on....keep holding the start button and move the probe to the starter solenoid. It's suppose to have volts on both terminals.I suspect that the starter side will be dead and the battery. side is OK..
If you don't mind a good spark...while still holding the start button down,you could use the probe and short the 2 lugs together. It should crank the engine.
This indicates the solenoid contacts are burnt and pitted.Replace it.

Solenoid is brand new and tested good. Also I rode my bike today so it will not clunk again until after it sits for at least 3 days. If I start it the next day or even 2 days later it starts 100% of the time. Problem is consistantly after sitting 3 days or more. That is why I tend to lean towards hydrolock.

Don't overlook the starter button. Remove the switch, pry open (don't loose the spring) and clean the contacts. I had to trim out some plastic from around the metal strip that contacts the terminals. You may also notice a problem with the headlight not coming on until you wiggle the starter button. I had this problem on a 78 GL1000, I assume the 1100 has the same setup that cuts out the headlight when the starter is engaged. Good luck and don't overlook the simple things.

I'll check starter button today. Never had any problem with headlight not coming on until button was wiggled. yes the headlight does cutout when starter button is pushed to send all power to starter. I am still stuck on why everything is good for 2 days after riding and the problem doesn't occur til the 3rd day or beyond. If I just rode more no problem. The time is the constant to the problem that has me baffled.

Good details.yes a tiny amount of raw gas will lock it.bump the starter and it will eventually squeeze the fuel out of the cylinder.
I don't suppose you turn off the gas when you park the bike for the 3 days do you???

I don't turn the gas off when I park, but I am going to try and see if that helps. I am afraid I am going to bend a rod by bumping it to much if it is hydrolocked. 2 days ago I had to hit it 6 times before it fire up. I feel that is 5 times to many.

oh it will If hydrolocking is the problem. it is common too.even the manufacturer suggests turning off the fuel If it sets more than a day.
Don't you remember the part that says..." turn off fuel when not in use"....Well I guess there is a reason for that afterall

Virgil! You're a genius! I read this thread and fixed my bike! I had gas in cylinder 2 and 4 got it out and my bike fired right up! I never shut the fuel valve off in fact I never even look at it! It was on reserve can that cause flooding?

I'm no genius by any stretch of the imagination.But thanks :)
Leaving it on reserve doesn't "cause" the hydrolock,a leaking needle valve did.
Most every carb is subject to this one time or another.
Even after rebuilding mine,it too hydrolocked 3 months later.
I spent 3 hours trying to figure out what was wrong with the starter before I figured it out. :oops:
I could rig up a electric valve but opted to just turn off the gas each night instead.

That's what I decided to do. Just shut the valve off when I'm not running the bike. There are two good things that came from this. 1. My starter is all nice and clean and freshly greased. 2. When I was testing for a charge I found out I had an intermittetent problem. The three yellow wire plug was clean and had that dialectric grease on it but I pulled at each wire and one was broken off the terminal inside! Now that is all soldered and shrink tubed! That would have taken the fun out of a ride one day for sure!

I have been riding motorcycles for 46 years. You would think that I would remember by now what to do before and after each ride. But I never have just remembered. It isn't just old age, I get excited to get riding and just forget. And when I get home, I usually gotta pee real bad. :oops: I made a little list that hangs on top of my ignition keyhole, and I laminated it. The second thing on the list before riding, and after riding, is "Turn Off Fuel". Or "Turn On Fuel". I just went out and timed it. It takes 2.3491 seconds to turn the fuel on or off. It is never a good idea to overlook this. Guess what the first thing on the list is. You guessed it, "Thank God"
