Spark Plugs??? (AND WHY YOU CHOSE THEM!)
Well I've searched this for the past 2 hours and although much good information, can't really get a specific answer. I got a K4 600 that's got about 10K now and is starting to bog a bit more in all gears, but especially on take off. I'm 99% sure it's the plugs but am told by a few people to get the iridiums. Most of the searches say I used "this" plug or I used "that" plug and liked it, but my question is why? I'm not taking my bike to a track anytime soon due to money, I stunt alot, and only do occasional bursts maybe a few times a month, but mostly just cruise at 7-8K and shift between 6-10, so I think I'd be fine running just NGK that came from the factory.
Please don't respond with the iridium or NGK or etc. plug worked great. My question for everyone else is when you changed your plugs, why did you go with the specific brand or type that you put in your bike??? Maybe it was friends' reccomendation, power, mileage, long lasting? What was your reasoning for you buying your plug?
