After installing an 8" mini delkevic exhaust at ~6,500 miles my bike seemed to pop quite a bit after letting off the throttle, as expected. Recently it has been doing so more often and I noticed a lack of power in lower rpms.
Before changing the air filter I wanted to inspect/ change the spark plugs which I thought might give me an indication of whether the AFR is running lean or rich.
at 7,500, just last week, I replaced the stock plugs for the NGKCR8EIX plugs and through the consult of an autozone 'expert' I gapped the plug both at ~.030-.035 in. The IX spark plugs were originally set at 0.025 in. and I realized after installing them that iridium plugs are factory gapped to model specifications. :wacko:
Personally I feel as though increasing the gap size would provide more probability for electron collision, therefore greater fuel combustion. But in the same token if the bike does not compensate by increasing its voltage output then increasing the gap would have the opposite effect? Thus far, the bike has been running much better than before the spark plugs were replaced, in essence it is a lot more responsive, but its only been a week.
Im not knowledgable in the topic so if gapping the iridium spark plugs I used was a horrendous mistake, please let me know ! :emot-pray:
as far as the old plugs go, I have attached a couple of pictures for some additional advice. I am sorry if i sound ignorant but they seem to be a combination of tan, black and white so I am not quite sure whether my bike is running lean, rich, or perfect haha any clues? :grin2:
