I seem to get what i'm assuming is pinging(sounds like popcorn popping) and hesitation while around 3-4000 rpms in 3-5 gear. Its around the 1/4 throttle mark. Its only at that certain spot as I back off or throttle up just a hair and its gone or I get the problem. Any suggestions?

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Take it to the dealer. Could be anything.:dontknow:
Yeah, the nearest dealer is 6 hrs away... my dealer is 14 hrs away. I was wonderin if any others had this problem an what it was so I could call them up and tell them to get the parts ready and i'll show up when there ready.
Yeah I did that as in the fall I installed the eveluzion race filter,o2 and fuel presure mods and thats when I noticed it. Ken said to fun premium and see, so Thats what I did when I got the bike out last week. I paid more attention this year as last year I only had a couple days of insurance left, thats when I noticed it only doing it at a certain throttle position and not at a certain speed /rpm as I thought.

Well that's a lot of mods you got going there Bro, you didn't tell us that part...I would say you need a Juicebox and start tweaking it with that.

Whoops... just caught this... has the bike been sitting all winter? That certainly won't help any pre-existing conditions. Gas stale?
And, I just read Lamont's post... you do have a lot of engine-affecting mods on. And, you inferred that the problem started after the install of those mods. I'd personally try backing off those one at a time... starting with the O2 eliminator.
I'm running custom duals, with the race air box and a TBR Juice Box... de-installed the O2 eliminator off... and it runs really strong with no problems... other than intake noise.

It did sit all winter I do add fuel stabalizer to all my toys that sit through the winter. I was running regular but when I took it out I siphoned out the fuel down to 1 bar and drove to the gas station for premium. It may have been doing it before stock(don't think so) but with the open intake you can really hear it. I know last year I upped the fuel pressure, can't remember to what but it really rann ****ty so ken suggested droping it down to 55 ish.

My suggestion again is to re-install the O2 sensor... so the machine can help with varying the fuel as needed. The O2 eliminator does nothing other than to enrichen the fuel mix across the board. You're already doing that with the FP regulator.
Easy step one - reinstall the O2 sensor... and test... then move on to the next step.

:agree:
Why take out the one thing that can help. You need to put the sensor back in, disconnect your battery and let it set for 20 min. or so and then see how see acts. I would still get the Juicebox too. You went this far with the mod so don't use cheap tricks to try and get the job done.
I hope so. How should it be done whilerunning? I remember hearing somthing about plugging something so the suage won't bounce around at idle. Its a pain in the ass but I turn on the key to get pressure an dadjust what I need then I fire up the bike and turn it off then I bleed the pressure from the guage and turn on the key to see if the pressure is still where I set it at.
What sensor the stock o2 or leane the o2 deleter in? Im guess i'll have to get the juice box I wasn't sure how much it would help as i'm not stock. I didn't want to bring it into the dealer just incase it was something I did then I have to pay them and possibly have problems with the warranty.

I have a similiar issue. Mine does that and around the same rpm 3900-4300 if I am running at a steady pace in any gear, I get surging also. I took the spyder to the dealer, and after having it there all day they determined it was the Hindle exhaust, and that it is actually common with a Hindle to have the machine run this way. Not sure I believe them, but all other systems checked out fine they said. I also tried the o2 mod as suggested in another part of this forum, but that had no effect.
Now that you mention it I did add the hindle at the same time as the rest of the engine mods.

Put the STOCK O2 SENSOR in as a first step in determining the problem. It is the quickest, easiest thing to start off with.

That's the first I've heard that the Hindle will cause a lean condition. Considering there are probably more Spyder riders here than all the customers your dealer has I find it odd that what they call a common issue hasn't been trumped up here?
Am I just missing something, maybe I need to do a better search.
Perhaps you should ask your dealer to use their ECM tools and reflash your ECM with the base map. Then do the 15 minute reset procedure just for good luck. It's too bad there aren't more Spyders on the road or that BRP doesn't sell an ECM tool like Harley does with their Race Tuner. I worked with the creators of the Harley Race Tuner, TTS out in SoCal. Some minor tweaks here and there and I could really clean up the EPA crap that's in the maps now. I just HATE piggyback devices so something like a PowerCommander just rubs me the wrong way.

Nope... you got it right. The stock setup will compensate for the Hindle... but he is no longer stock... O2 eliminator installed, fuel pressure increased and the much more free-flowing race filter installed.
