Spark Plugs.....

Got new plugs for the 2004 VL 800. I wanted to get iridium for the longevity. Ordered them at O' Reilly's as they didn't have them in stock and thought they were getting me the NGK's.

When I went and picked them up they ordered the Autolite brand. Anyone used these, and how did you like them. I am sure they will work, but anything that requires that you take both seats off, and the tank, I would prefer be the best in order to pull the bike apart as little as possible.

Thanks
Marty

My experience has been that the spark plug recommended by the manufacturer is the one that will give you the best performance for the money.

For my money, the standard NGK plugs are more than adequate for the riding and performance that I desire.

So far as the fancy new plugs go, our bikes are not usually of the high mileage use for which these spark plugs are intended even though some people like the idea of them.

They may have a slight advantages in some circumstances but they would be very limited under our operating conditions.

With our bikes, it is recommended to adjust the valves periodically anyway which should require the removal of the spark plugs in order To position the valves for adjustment.

Inspection, cleaning and adjustment or replacement would normally take place at that time.

I don't remember having to remove seats or tank to replace spark plugs? Does take a flexible adapter on an extension and ratchet.

Well I have seen some how "to's" on this forum about changing the plugs on the 2004 and while some said they did it without the tank removed, they would take it off in the future as it was a pain not to. And really I want to go through and replace all the vacuum and fuel lines anyway, so might as well just take it off and go through it completely.

And I have seen others talk about they really like the improved starting with the iridium plugs, I was just looking for a real live user (if any) of this brand of plug.

Thanks
Marty

Marty,

Copper is a better conductor than platinum or iridium so they would be better for starting.
Platinum and iridium are designed for longevity. Car manufacturers use those materials so they can tout low maintenance because you don't have to tune up as often (60-100,000 miles). Even in a car it isn't good to leave the plugs in that long because they may seize upon removal.
As far as autolite plugs go, they are a no no in the sport bike world. They break apart and cause engine damage, especially in a ninja 250 because it runs at such high revs all the time to maintain its powerband.
NGK only in those.
Just my opinion but I would stick to the copper NGK's.

Ron, that's kinda what I thought on the stick with NGK. I ordered a set of Iridium NGK's. I have read several posts that indicated that the Iridium plugs start the Volusia better and run smoother. I wouldn't ever leave a set of plugs in a cycle that long, and I always put Never Seize on my plugs when installing. I have a can of aluminum based Never Seize that I got in 69 working for the railroad, am still using it, that stuff goes forever. I will leave the autolite plugs in the package, actually I will take them back, I asked for NGK and they ordered these.

Thanks for the info!
Marty

Marty:

There are a few subjects that will get you a range of opinions and start arguments on the boards. People are very opinionated about things like, tire preferences, performance mods and, yes, even spark plugs. Just remember that opinions are usual worth exactly what it costs you. That being said, I am a big fan of using what the manufacturer spec'd as OEM, in this case copper core. While I don't have the depth of experience on the motorcycle front in this manner, I've played the upgrade game on my trucks and cars with mixed results. In the end, I've found that OEM spec works the best, as that's what the engineers designed the ignition system for. Again, just my opinion.

As far as using anti-seize on spark plugs....that's a whole other can of worms you just opened. LOL!

Ride Safe and Often


This work thing is beginning to seriously interfering with the much more important fun parts of life.
I need to get my priorities straight!

Save your money. A $2 copper produces the same spark as a $15 iridium plug. You will see ZERO performance improvements with the Iridium spark plugs. In fact, the only thing they will do for certain is separate you from your hard earned money.

Precious metal spark plugs are intended for severe duty, long service life applications. Like changing your plugs every 100000 miles. Your bike has a 7500 mile service interval for the valve inspection, meaning you'll be pulling the plugs anyway to check the valve clearance. There is absolutely no advantage to putting them in your bike.

I meant wouldn't be better for starting but like lelimoman pointed out, you will get lots of opinions on here about maintenance related items..... don't ever mention oil... Lololol
Glad you stuck with the NGK's even if they are iridium.... Lol
I hope they work well for you. My daughter has a ninja 250 and she hardly ever rides it so I feel your pain on starting a carbed bike, especially after it's been sitting a few weeks. I use sta-bil, drain the bowls of fuel, battery charger,etc. Prime the bowls, adjust the choke and it just doesn't like to start well after sitting over 2 weeks. Ride it once a week and it starts up great, let it sit and it's a fight every time. Smh

Keep the rubber side down!
