Looking for advice on my 1981 cb750f, I have been trying to chase down a running issue for a couple weeks, low power, backfiring, slow rpm pickup. The other day I accidentally got ahold of the champion resistor spark plugs not knowing they were resistors and put them in, weird thing is that it ran amazing. It would tach out in neutral amazingly fast. Now my question is do I have a problem with my ignition system like my cdi box, wiring or coils etc. or does the difference in spark cover up a different problem. It does run a little lean due to pod filters but the carbs are recently rebuilt and are perfect inside. Just wanna make sure I head in the right direction trying to figure this out
