So I'm dealing with an 87 VT1100c. Last night I put on about 250km and parked it and went to local bike show, walked around for a couple hours came back to bike to leave and had a harder time getting it started, but efter about 10 minutes it started and off I went.
Was going to work this morning and it started right up in my driveway and I decided to take the long way to work (basically a 100km drive for a 10 minute ride to work lol) stopped at Tim Horton's to get a coffee, was in there for about 15 minutes came back out and no way will this pig start. Just cranks and cranks.
For the love of sweet baby jesus, please Hondashdow.net guru's help me get this going and out of that parking lot.
Are you out of gas??? Silly question that may be the problem. Could be the fuel supply tube in the tank has a restriction.
And if you can get some carb cleaner spray it in the intake as see if it tries to start. That would indicate a lack of fuel.
And flip the kill switch a few times.
Look at the battery connections and wiring.
If you have a multimeter test the battery volts before and as you crank. It may be low enough to starve the ignition for power.
So cold engine it starts; warm engine it does not. What about your warm engine starting procedure: NO choke, slightly open throttle, push starter button. Don't twist throttle when starting. Just leave it slightly open.
If you think the engine is flooded: No Choke; full throttle crank 5 seconds. If it starts, drop throttle, if not wait 10 secs and use warm start procedure above.
Basically you are either getting too much fuel or not enough air on restart so if your procedure is correct you may need to look for air restrictions (filter?) or at worst case an incorrect pilot A/F mixture.
Here is an easy test when there is no spark. Get a 12 volt test light and touch it to one of the coil terminals with the key on. One should have battery power. (They both may show power when it is not cranked that is OK too). Then crank the bike and see if the other one will blink. That is the grounding signal from the CDI. If no power trace that. If no blink then the CDI or pulse generator is not working. Check the wiring to them first. Test both coils. Get a manual and follow the wiring for the ignition components. If it blinks then the coils are supposed to be firing the plugs. Check fire at the plug . You may have to inspect the kill switch an any other component that kills the ignition operation.
Are you zeroing your meter to see what it says when the 2 probes are touched together? It has to be subtracted. Also do you have the wires unhooked from the coils, or you will be measuring other parts of the circuit also.
If you are sure of those readings and the manual says otherwise, it may be time to shop for coils. Do they look like they came with the bike or did someone put on aftermarket coils?
If you put them on the bike and they're both reading the same, it may be that your non-oem coils have higher resistance so the manual wouldn't be right.
Find the 4 pin connector that is in line from the pulse generators and test the 2 pair for voltage when it is being cranked.
One side is white/blue and a blue. The other is white/ yellow and a yellow. Should be a small voltage across when they are triggered.
Did you check the ignition 10 amp. fuse? If it is good then you should have batt. power to the black wire on the CDI.
Unplug the connector from the cdi, put the gnd of the led into yellow/white and pos into yellow and crank the bike. Then do the same for the white/blue and blue. The LED should blink.
Well I'll be trying that tonight after work. Getting very close to buying a Harley, at least then the break downs and sight of me trailering my bike home will make sense.
black one with a green wire / black wire / blue with yellow stripe / yellow with blue stripe.
With my test light I get a red light on all wires except the green.
White oneone with a yellow wire / blue wire / white with yellow stripe / white with blue stripe.
With my test light and cranking the engine I get a flashing green light on both wires with the stripes on them.
Green is ground. I'm attaching a wiring chart just for your reference. The CDI is Ignition Control Module. It sounds like your pulsar is working and it also seems like the cdi is sending pulse signals to your coils. What light are you using? Just an led?
Sounds like you have a test light that is safe to use with computer circuits and has 2 or 3 lights. The red one should show battery voltage, and the green would show a ground. Try it on the battery and see if that is what it indicated. Then you know what the lights are indicating when you have it on the bike circuits. Red would show when there is power, and the green would show a grounding signal as on the coils when the CDI is trying to make them fire the plugs. Good tool to have and get to know.
