Spark plug

What measurement do you gap them at? what do the plugs come standard bcr8es

Also How important is it to have correct gapping.. Because I did not gap my plugs.  When i do it what changes should i expect Re do ignition timing ?
Experiencing high idle issuses when warm this wouldn't be the culprit would it

I think the gap is between 0.6 -0.8 for a pulsar the plugs will be pr gapped but as they do a wide spectrum of cars it will not nessarily be gapped right for the pulsar ....you will not not need to touch any timing or anything else to change plugs

If your not running big power then gap the plugs to 0.7 That should be fine
