didn't come up with much. Does the ZX11 take to Iridium plugs well or just run the CR9E NGK it calls for? If the Iridium plug is good, what is the NGK number?
There are several reasons above, plus some more to follow. For example the smaller the spark plug's electrode the more concentrated the electric potential at the electrode. The stronger the electric field, the lower the required voltage. As a result contribution is good for all types of driving, the engine starts easily and acceleration improves. Iridium Spark plugs, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower - better gas mileage.
Same plugs with 60k miles on them?
It's only in the advertising that they tell you and you think you have more power.
There is no way anyone can tell a diff by their seat of the pants dyno from a regular plug and an iridium.
It's just a better plug for longer service.
Because I didn't know if the bike takes to the plugs well or not. Iridium plugs are new tech and our bikes are old tech. My Honda Aquatrax jet ski uses them and you have to be careful with them. If you just crank the jet ski to run it for 30 to 60 seconds and not let the ski warm up you can foul the plugs easily. Just wanted to make sure these aren't the same in our bikes. Now the Aquatrax is FI instead of carbs but on the ZRXOA site they tell you not to run the regular NGK plugs on choke too long or you will foul them and they are the regular NGK's not iridium's. So that's why I asked. Thanks for the replies. Just looking for answers.If it's only 9 bucks diff, why even bother to ask the question?
I agree and disagree with you, if your bike runs right you will not get any more power out of it. If you run rich it will help or like you said an old engine that burns a little oil will run better. Some guys who run for top speed will run there bikes a little richer @ top end to keep the pistons a bit cooler so those guys wil notice an improvement but for most of us regular street riders will not see any improvement.The iridium number should just add IX.
Unless you're racing or keeping your bike for 100,000 miles, save your money and get the standard plug. You'll never notice the difference.
I think it's the fuel mapping on the Aquatrax itself. Seemed to be a known problem. I did what they said on the board and kept a fresh set of plugs in the glove box. Never used them in 3 years and gave them to the guy I sold them to. I had 2 of the turbo's, a 2 seater and 3 seater. Fun skis but I like the early to mid 90's Seadoo's. 2 stroke motors with power valves and 350 to 400 pounds, not 900 pounds like the 4 stroke Honda Aquatrax. Much more fun to sling around and dirt bike style on the water. The one's now are big, smooth and fast. In other words they have refined out allot of the fun but hey, that's just me...
NEVER had an issue with plug fouling....
