Hello all,
I was going to put in an NGK iridium plug in my downtown. Do you have to take the seat bucket off to change the plug or can you get to it from underneath and not have to take out the bucket? Thanks!

jimboeau, I just changed mine last week. You do not have to take the seat bucket off. I took mine off, but it was easier access going up between the side and center stand and looking through the "air vent " Located on the side, between the foot rest and sea.It's a little uncomfortable, kneeling or laying on the ground, but taking the seat tube out did not provide better access.

Thanks Rich, that was easy. Took about 10 minutes. I was expecting the original plug to be really tight but it wasn't bad at all.

Glad to hear, I also did the TPS/ ISC reset the other day, because I really didn't see a big difference with the iridium plug. Took a ride to the Statue Of Liberty, this morning and noticed it definitely ran better. Nice idle and no hesitation on acceleration.

That must have been a bit wet. Did you flood the engine? :)

I am guessing not so if you take a really, really, fast run off the pier. :)

Lol, I'll be more specific, took a ride to Liberty State Park!! Also Ellis Island , in the background and a tribute the 9/11 victims of the World Trade Center!!!

Has anyone ever used an E3 performance plug? Any good? Any difference between that and the iridium?

I ordered the e3.38, so we shall see.
-
TANware, me too!!! E3.38, should be getting it today or tomorrow. I was just curious if anyone else had tried one. I honestly didn't see any difference with the iridium plug. I doubt this one will make a difference either, but we shall see I look forward to your review, I will do the same.

I found, with high test fuel, the engine seemed to fire more consistently. Performance did not improve but MPG did slightly.
-
Got mine in today. First impression is the idle went down from 1,700 RPM to 1,500 but this could be a cold engine. after a good warm up and run in the RPM seems back up to 1,700. Took it for a short ride.
Now the wind here is 10-20 MPH so I took it to the local interstate for a 2 mile run with and into the wind. With the wind at my back I saw 95 MPH indicated and there still felt like there was some pull left over, into the wind was 87 MPH with occasional nudge to 90 MPH. I should note at 65 MPH indicated the stationary solar radar signs will show this bike doing 65MPH, for however accurate they are. Also the bike at 75MPH was a breeze to keep up.
Went for another ride, longer haul and it ran great. Found at dusk with the wind calmed down on a flat at WOT got too 93 MPH indicated and I think that was about all it would go. Much more than I care to use this bike at. On our GSP here I found keeping with traffic at 70-75 MPH the bike does well.
-
Thanks for the update. I received mine yesterday, but didn't have time to install. Did you do a TPS/ISC reset also? The last time I changed out the plug, the engine icon would stay lite, for longer than usual. Did the reset and went back to normal.
Thanks again..

I did not reset as wanted to see if there ws any change to the bike operating as it was.
-
Ok, I think I will do the same. (http://uploads.tapatalk-cdn.com/20160703/aee730a0a2f26925c0f03b681040a88f.jpg)

It is amazing how fast we buy into gimmicks. Multi prong plugs of one type or another have been around for years. Hopefully these are actually better but I figure other than wear can be no worse.
Edit; an added note is I had about 20 miles on a tank of gas when I put in the plug. After the rides and some WOT the MPG on the tank was 73, no too shabby.
-
Wow, not bad at all. Thanks for the update. Been a busy weekend, it's going to be a rainy day today. I'll keep the DT in the garage and change the plug. I let you know if I see a difference, with this amazing,new technologically, advanced plug [emoji16][emoji106]

Finally changed plug to E3 today. Took it out for a quick spin . Did not do TPS/ISC reset. To early to tell, but it seems it has a little more kick. Got it up to about 80-85mph, still had some throttle left. But it's hard to go any faster than that on North Jersey highways at 4pm. So far , so good

I am interested, what does this spark plug do for the bike?
-
The idea is that with the higher RPM's these is a very short time frame for the explosion to happen within the combustion chamber. The faster this explosion happens the more power from expansion within the chamber. The Iridium plugs raaised firing consistency helping a bit and now the E3 plugs supposedly raise the firing time yet again. Again this is the theory anyway.
-
Yep, what TANWare said...For $10 , I figured I'd give it a try. I like it so far

Thanks great explanation :)

As a side note though the Givi screen is due in today. I just got 80MPG from a fueling but I will probably get less in the future so I won't be able to make comparisons.
-
Ok, got the new screen in. With out a doubt it is taller. During a short ride I have noticed if I sit with proper posture then I slightly look over the screen, without trying to sit erect I look threw the glass.
At 30 MPH and above there is a slight whistling and at 40 MPH it is a solid whistle. This does though move allot more air than the old screen. Riding at 65 MPH there is little buffeting of air, where as there was a fair amount before. I also in stagnated air at WOT got to 89-90 MPH, so it does seem there is a slight drop of 2-3 MPH. I did notice 65 MPH was now 6,000 RPM instead of 6,100 as before, this was not expected.
I may later decide to cut thee screen down a bit, but I will live with it for a while as is to see what might be best.
