Weak spark problem - Fe 600 E Husaberg Motorcycles

Your engine has a separate coil for each cylinder/spark plug. Are they all weak? How did you determine the spark was weak? And is the weak spark causing a problem?
You're guessing at a cause, but haven't stated what the problem is. Post a new question and tell us what type of problem you're experiencing -- engine doesn't start/run, engine doesn't idle, poor performance, etc. Also include engine size and type in the question.

Hi, I do a lot with these bikes, I think if you are getting a weak spark there is a couple things to check. First, do you understand how it builds the power to create the spark? The magnet in the flywheel has to be very close to the magnito or coil, if the gap is too much it will cause a weak spark, if the magnet is weak, weak spark, if the coil is shorting internally, weak spark. If the plug wire is damaged, weak spark. I hope this helps you.

this can be caused by a weak battery check battery and charging system to verify a good working system. it could also be a weak coil not being able to supply enough output voltage for the ignition system. you don`t say if its weak coming out of the coil or at the plugs. if spark is weak at the plugs it could be a bad cap/rotor, ignition wires. it could also be an ignition module problem or pick-up coil in the distributor.

How do you know its a weak spark? Is this a visual check? Will the bike start with the correct new spark plug?
On some bikes, you can hardly notice the spark when looking at the spark plug laying on the head, Try looking at night in the DARK!

pull flywheel and replace sheer key on flywheel to get spark on time

Check to see haw strong the spark is coming out the dist cap. If it is weak there, possible bad cap/rotor/coil/ module. Make sure the wire from the coil to the cap is good.

Yep, that is alright as the weak spark is a wasted spark. It should goes on each ignition cable a STRONG then WEAK sparks. It is just fine in your ignition.
If you find this advise helpful then rate it please. thanks

If the spark is weak, try disconnecting kill switch, still weak need new ign module

How do you know that the spark is weak?
Replace spark plug.
Check spark plug wire for leaks.
Replace fuel.
Clean points and reset.
If there is a battery check that it is at 12.5 during starting.

its the coil or magneto one of these two will cuase a weak spark they are simple to replace though
