Motorcycle Questions? Ask a Mechanic.
Hi John, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially, is the idle high / uncontrollable when the Honda "...misses and pops..." ?
Still, have you tried:
The above post on the electrical/battery is an alternative suspect to a fuel issue.
Yes please; an over (charging) voltage would mess the electronics,
Replace the plugs.
Other than a fuel mix issue, it is possible also for a developing vacuum leak.
The above voltage check would be the easiest to do hence the first to try.
When the symptom comes up again, check the charging voltage. If it is higher than 15 Volts @ 4,000 RPM, then the ignition system woulkd be constantly kicking in auto-protect and the spark would be erratic.
As posted above, this would be the easiest to check hecne should be considered and tried first.
The other possibility is a developing vacuum leak which by its very nature more difficult to trace.
Good luck and thank you too for the opportunity to be able to share the information.
Hi again John,
Possibly but if it were an ignition coil issue, then the no-spark would be exhibited on two (2) spark plugs as each coil is commonly powering 2 spark plugs.
It may more be the spark plug wire from the coil and/or the cap of that particular spark plug that misses.
The same coil powers the two (2) front spark plugs and same coil for the 2 rear.
Left rear; check the high voltage wire from the ignition coil to the spark plug cap and/or even the cap itself.
Depending on the type of coil used, it may be removable hence can be replaced.
If not, then the rear ignition coil should be replaced.
Yes; it can still be the coil even if just 1 cylinder has no-spark.
