Cool '06 Honda Shadow Spirit 750 Issues

Hello,

As you can tell by this thread title, I drive a '06 Honda Shadow Spirit 750.

I Just about it a few months back and everything seemed fine.

I am new to riding and I am at the very early stages of learning to fix my bike.

The issues:

- Sputtering when throttle
- back firing when start
- odometer flashing on and off

I read a few threads and things were all over the place.
possibilities included:

-sparkplugs
-air intake issues
-electrical issues

Could this be a coolant issue?
Oil?
Easy fixes?

I am just lost as I am such a noob.

Any help would be greatly appreciated

Thanks all!

Also, It just died on me. If that helps with a diagnosis.
I saw some oil or something in the air filter. not sure what that says. I ordered a new filter and just bought some new spark plugs.

I need to buy the stock spark plug tool from honda to change the sparks.

Not sure what this issue is but a resolve would make my life easier.

Thanks all

Check your battery.

Check the basics first. I think the spark plugs are a good start. You can buy any spark plug wrench (just make sure you get the right size) from a hardware store and use an extension to get them out. Look at the color of the spark plugs as they can be a good indication of how it is running. A quick google search will be helpful for that.

I wouldn't be too concerned about the oil in the filter. That could happen if someone put too much oil in it. It should probably be replaced though if you are unsure how old it is.

Make sure all electrical connections are tight and clean any corrosion in the connections and look for loose or chafing wires. Just make sure you disconnect the battery before touching anything electrical.

How many miles are on it?

Best of luck!

I tried to buy a socket for it but it stumped both the oreilly guy and myself. It just wouldn't grab the spark plug.
Know the exact size that would be a fit?

It turned back on after tightening the loose battery cable.

Would that really cause ALL of those symptoms?

I'll be changing out the plugs and air filter too.

What type of coolant should I use?
Silicate free? brand? type?

Thank you so much!!!

You need power to fire the coils and keep it running.

Checking and changing the fluids is a good thing to do with any new vehicle. Since the coolant change is not the easiest, you just get a hydrometer and check to see what condition it is in. Also drain your carbs for any trapped water, add some fuel treatment for any old gas or water in the tank and replace the fuel filter. Clean, lube and check chain tension along with sprocket wear.

Otherwise ride it.

As I stated earlier, check the battery. A weak battery will cause those symptoms. You need a thinwall deep 18mm socket for the sparkplugs.

You said loose battery cable, that will cause a lot of problems.
If you can get it running now, put a meter on the battery. Look for about 12.5 volts sitting, engine off. Over 9.5 volts cranking. And about 13.5 to 14.5 volts when you rev it up to 3000 RPM. That will tell most of the info you need for the battery and charging system.
