Question about Harley Davidson Harley-Davidson Motorcycle Desktop Telephone
I have a problem with a 1996 honda magna. 3 of the 4 spark plugs will not fire. I have replaced them and in one day they will foul out and it will start backfireing. its the same 3 that keep fouling out and the other one will always fire.
I would 1st check to make sure the spark plug boots on your older Honda aren't arcing out prior to getting to the plugs. Anytime spark has a chance it'll take the least path of resistance and arc to the cylinder head before it makes it to the plug causing a very weak spark thus fouling out your plugs. Chances of 3 of 4 cylinders have an issue with compression is unlikely considering most older metric bikes don't see much use, plus, if there was a compression issue, it'd likely be across all 4 cylinders and not just 1. New plug boots are super cheap (around $7-$12 ea) and well worth the easy effort to see if that's the cause before you go rebuilding your engine...... It's a $48 vs. $1000 fix.

Do a compression check and lets go from there. Bad rings CAN cause fouling
