I'm going to do the 7500 mile service this week. I [b]will[/] be changing the sparkplugs. Should I go with the factory NGK or a different model/ brand?

I'd say factory.

Yep. I looked into it and NGK doesn't offer a better plug than what's already in there thats worth switch to.

This thread can die.

Leave the stock part number.

NGK CR9EIA-9

wasting your bucks at 7500, ran mine to 19000 and still looked spot on

Fuck you. After pulling my and scrutinizing and examining them 7500 was the right time to pull them with the wear and tear they showed. Their is no reason to wait till they are burnt up pieces of shit to replace them.

Believe it or not, it's more a balanced resistance is the plug to spark stick. The metal is just that. It's arc is what you are changing. The tip is machined off? A perfect 90 to 180° cut? So spark likes edges. On a flat table it floats around. At the edge of the table is air, so that edge is the shortest path, not moving on top of a table looking for ground.

So technically you are changing the edge, or back to the shortest distance is the path. And as nasty has seen, it's all that R&D in the book that calls the parts and when to replace them. So on the test tracks, the new plug, the new tires, the new map, the new neck, all this is timed in hours spent wearing down. The plugs are thrown at 7,500 because that is the life of the plug's peak performance.

If you want a hunting spark, then a miss, then not be at peak performance, then keep the plugs in longer.

I was going to let this pass but I feel I should reply to this dip wad ( tampax to you bonny lad )as you had decided to change your plugs WHY ask the question, people like you who think they ride 10-10 put Rossi to shame every time you put your leg over the saddle make me laugh. you could probably run it on 3 plugs and still not get flat out.

At least I do my own service. The bike just rolled 8000 I am going pull them if the book says. Reading what the plugs had to say about engine health is what I was really after. $40 for a new set of plugs is a hell of a lot cheaper than other retarded useless shit people think they gotta have, several times over. I was already in there for tb sync, might as well do the plugs while I'm there. For peak performance and engine efficiency, I believe Kawi has it right at 7500.

well nasty having covered 35000 on my gen2, similar mileage on my gen 1, over 80000 on 3 x black birds I could go on, being an engineer till my retirement 3 yrs ago I feel I have learned one or two things, and how not to waste hard earned cash to feed stealer is one, here's another one for you I did not do my shims till the same 19000 service and although I changed and swapped few none were so far out of spec, I have done my own servicing since my first B S A C11G in the sixty's, but hey it's your cash and time when you could be playing on your tractor.

What's the difference dude? I have a short ridding season, one set of plugs each year. I can stay home on one Saturday evening and not go to the bar, spend $40 dollars on plugs instead of $80+ on a bar tab. I bought a high performance engine on two wheels, not a point A to point B fucking use and abuse me who the fuck cares about maintance as long as it runs piece of fucking shit moped.

^^^^^^^ That right there says it all.

can you try your post in ENGLISH with out knob head expletive. thank you

Piss off

in my opinion... if i am going to go out and spend $13,300.00 (left over price) on what i'd consider a super high performance machine, i am not going to second guess what the manufacturer suggests. even tho its only a suggestion. if i can afford 13 grand for a high performance machine, why on earth would i skimp out on maintenance. these machines are made with such tight tolerances (not like back in the 60's...) that they are sensitive in every aspect. not to mention the warranty. in order to keep your warranty, you need to maintain the machine as your supposed to. better safe than sorry in my book.

i understand about staying with factory eqiopment, i.e. ngk plugs. but, has anyone heard about how e3 plugs are in these bikes. i have them in my silverado and i think they are just fine. would they really make a difference as far as hp goes as they claim?

The NGK metal used is one advantage. The narrow center electrode is taking up less space, if you like more metal than fuel/air displacing some 3 point spark for a side electrode taking up twice the space of a side electrode. The porcelain is the heat range, so that has to comply. The resistance rating is the other.

You are paying the large for the longer lasting, less filling, right resistance, heat and detonation all built into that plug. It had as much time [R&D] probably, with engines sitting in dyno rooms all running sustained at redline. Probes out the ass and one spark drops out at an average rate is shut the engine down, change the oil and the plugs. It was running as long as 7,500 miles was the cutoff of performance @ redline. Same kind of R&D with the tire company, the black box company, the fuel injection company, all working on this bike.

3E had no involvement WATT/WOTsoever with the building of this bike. I rest my case.

Hey nasty my bro! Fuckin a on gettin that service done! Plugs are not like some ancillary part of the whole system. THEY ARE THE FUCKIN SPARK PLUG AFTER ALL. So the plug is the integral and key spark component right? You are 100% CORRECT in making sure by replacement that they are flawless. I change em about as often as you, why? So that my combustion is assuredly not missing anything in that KEY component. I can guess like that fuckin dickwad battlequack with all the bullshit letters after his name, or I CAN BE POSITIVE LIKE NASTY. Hmmm. Who be the fuckin idiot. Anyone with common sense comes to this simple logical conclusion. Ya get some loser trying to mileage out his bike in shit shape and misery loves company. Obviously his common sense applied intellect as regards to the internal combustion engine is so far fuckin off as to be lost. This guy is worried about spending a couple a bucks on essential internal componentry? Well, that speaks loud enough for me. :))) old intolerant C would tell him to fuck himself. New C says get it ya doucher, run your shit into the ground. Show us how fuckin smart ya are. Wait till ur leak down test comes back fucked sideways from Sunday and then just scrape it right??? Hahahaha. Have you ever followed any of your own bullshit thought processes to their conclusion??

Thanks Cblast. In answer to your question,...no, I was never a member of "the org". No disrespect to anyone, but I can proudly say that I've never owned a Suzuki in my entire life. Sorry for the thread hijack.
