New vision - trying to figure out what the LAST owner did.

2482 41
Okay this is probably a tough one.

The shop I got the bike from has NO CLUE what the owner did. I've asked if they'll reach out to him and pray they will talk.

<- Here's the video from the dealer on my bike. They list it as"open exhaust", and the baffles are gone. I dunno if he did a Witchdoctors swap or what.

I want to fix a couple issues. The first is it's LOUD.. I want to get that to a quieter level. I don't have pops on decel unless the RPM is too low and then I get one big pop that's it.
Second, it 'chugs' at low speed. The smoothness for low speed maneuvers is not there, it always on the verge of a stall it feels like.
When driving, 25/35/45 it doesn't seem to have a happy RPM range at all. It's not really 'smooth' until I hit 4th gear and 50mph and then bammo smooooooth as butter. Exhaust quiets down a lot everything.

Anyone have any tips/tricks for figuring out what's been done? My buddy has a CC and he's got cams/power commander/exhaust done, his pops on decel like a typical baffle removal would do, different than mine. But that low speed chug is very similar to mine.

And if you ARE the owner and happen to see this. Duuuude help me out!! lol

Welcome to the vog and the new to you Vision.

a couple of things to check/be aware of.

exhaust. Yes, could be just a recore from WD or Miller or Ness Big Honkers. If you want them quieter, your best bet is to have them reworked by Ragin Cajun. On here as @crosscountryla He has reworked more mufflers than anyone and has more happy customers than you can shake a stick at.

is there a power commander on the bike? Usually under the panel right in front of the seat or the side panel under the right side of the seat.

Vics do NOT like low rpm. Keep RPMs at 2500+ (yes, even at slow speeds as much as possible) to avoid the “chug”. you are likely lugging the motor.

if elevation or weather has changed, you can do the IAC and TPS reset procedures just to make sure. Do a search on here for how to do them.

I read that about the RPMs on the forum, something I'll keep a closer eye on. My previous bikes have been Magnas, and the vision's RPM literally tops off a few thousand RPM before they even redline heh. Thanks for the IAC/TPS info! I haven't come across that in my searches yet!!!! It went from NC mountains to TN Lowlands.
Let me see if I can find the links for you.

stock cams in Vics usually fall off around 4K-4500 even through the redline is 5300. Lloydz aftermarket cams will pull until 6k. Highly recommend.

IAC reset: Check Engine light/IAC problem

TPS reset: TPS reset procedure

also download a manual here courtesy of fellow Vog member BBob. Just get the closest model year to yours (most all Visions are the same except some differences with the 08-09 bikes.

Thanks huge MD2420, first thing I did after your post was look for that reset. Made a very noticeable difference! Did another good ride and kept the bike at a higher RPM. It seemed a bit happier there.

Also finally got to checking the rear suspension... yeah... 0 psi.. figured it was 'low' but dayum not zero. Soo THAT also helped :)
Glad to hear it helped! Mine loves to cruise at 2800-3000 all day long and in any gear.

Thanks to a lot of helpful replies and messages from folks!!!

crosscountryla was able to identify the pipes I've got on right now as the Arlen Ness Big Honkers and is able to help me out with reworking them to something closer to my goals, big kudos/thanks there!

Gonna start stripping the seat off to look for anything hidden underneath and the air filter as well. I THINK I spotted a plug earlier that seemed odd to be 'sitting there' just behind the engine i'll post up tomorrow and hopefully someone can identify what it is.
Dave is the man when it comes to exhaust.

check for any piggyback wiring on your injector wires and that will tell you if it has a PCV. In addition to checking the 2 spots I already mentioned where the module may be.

re: random plugs, Polaris used the same harness for a bunch of models and trims, so you may find some that are not plugged in anywhere because they don’t apply to your Vision.

a couple of other places to check your bike.
  • under the radio/center console is where the “top filter” is located. PO may have added it. If not, there will just be a block off plate there.
  • you could check for a timing wheel under the cam cover on the right side. Have to take the floorboard off (2 bolts) and then 5 bolts for the cam cover.
  • I’d check for the top filter and pcv first before pulling the cam cover. If it’s OEM, you may need to replace the gasket when reinstalling.

Agree with what MLR1 said re: the front filter (Vic had a performance washable one) and checking for the Top Filter as well. Having the PCV you likely have the Lloydz Adjustable timing wheel as well. Would be good to know what it is set at. So you should pop the cam cover off and take a look.

you can add the power commander app to your laptop and download the tune that is on it. I did that with mine so I always have a backup of it on my computer and a flash drive I carry on the bike.

Re: the plug as I mentioned before Polaris used the same harness for a lot of bikes, so it likely not used for your bike. Does it look like it has ever been plugged into anything?

I just checked my 2014 and also have the same white plug…not tied to anything. So I wouldn’t worry about it.

I think I remember reading somewhere that the plug was for the reverse kit but can't say with any confidence.
Certainly sounds plausible. It’s in the right area for it. @BrotherWind any chance you can look at yours and confirm that plug is for the reverse?

Would be great if it also had cams. After you confirm timing wheel, that may be your next check.

So my first gear is super slow. No get up and pull nothing, but when I hit second HOLY effing hell does it pull. Like shocked the hell out of me pull and I'm used to a 0-60 in 4ish seconds.
2nd, 3rd, 4th all pull hard. I am dead serious when I said I accidentally got up near that 150 mark. I was totally not expecting it. I haven't yet tried to bury the tach. I very much try to avoid that til I know a bike well enough to risk it.

My previous bikes didn't redline until 10k and buried at 12k. This thing is literally half that. so I have tried to keep it under 5k. But every inch of that 1-5k hauls ass in every gear except first. I actually find it kinda odd how underpowered first is, but honestly i'm getting used to it and it helps with the slow speed maneuvering.

Edit: I THINK i needed to be going 70ish for 6th to feel 'right' btw. Couldn't maintain it long on the stretch I had so I need more testing
Try to see if it continues to pull through 5k up to 6k. If so, you have cams.

I agree with MagVic…the Ness are probably costing you some low end torque. There is a natural dip in low end on these a bit anyway.

completely on the mark with “70” and not shifting into 6th until on or after that mph. That’s right in line with the rest of us.

have you heard back yet from the seller and whether the original owner is willing to chat with you?

Dealer is providing me his contact information, said they'd include it in the title paperwork they mail back. So just waiting on that then I can reach out and cross my fingers. Winter weather is fighting it's way in here so nice times to ride are dwindling heh..
Things I’d ask about.
  • was it dyno tuned or just a canned map from PC or The Vic Shop
  • Lloyd’s Top Filter?
  • Lloydz adjustable timing wheel?
  • Cams? If so, which ones.
  • Front fender fix done? (You can actually check this yourself…if there is a bolt halfway down the back half of the front fender, then it has been done…basically right where the brake lines run)
  • what oil did he use? Low enough mileage that it may not matter, but this could help in your decision on what to use going forward.

hi, what is the horsepower of your bike with all the upgrades? how many horses have become, and what is the torque?
With the Lloydz 501 cams, top filter, timing wheel & PCV with tune I’m at 115hp & 119tq at the rear wheel.

and if you take OEM, what were its characteristics?
And how long does it cut off the revs? Over 6000rpm
Characteristics are “it should have come from the factory like this”. Faster, smoother, pull up to 6000rpm. My PCV is actually set at 5800 (just the normal 500 above redline that is a checkbox in the software) and it pulls all the way to it.

only thing I would do different if starting over would be to get the Maximus ecu tune instead of the PCV piggyback and timing wheel (but it wasn’t available when I did mine)

You've got another 4-5 hundred rpm waiting on you there. Not that you'd use it that often, but when you did.......Yeah!
Yeah, I hear ya. I have to get an authorized shop and special code to extend it though. Maybe I can see if my dyno guy will do it on the fly.

unless someone on here has the code, then I can load it myself.

So got some new tips from crosscountryla, bout all i can do for the arlen ness big honkers slip ons to tone em down a bit. They help a lil bit. The neighbors aren't as pissed when I take off now and I can actually hear my radio hahaha.

Also got my backrest from utopia and OMG is this thing comfyyyy. ooo so much more relaxing. Haven't gotten a response on flywheel/cams yet, and I don't feel like taking stuff apart and replacing gaskets quite yet just to CHECK..

Next items are going to be adjusting the shifter/brake peddle. They feel a tad loose and need to adjust for my ride length, finding a vision trunk, and keeping my eye out for some stock mufflers to put back on some day.
For the shifter/brake slop there are brass replacement bushings you can get. Soooo much better than stock.

keep an eye on eBay for replacement mufflers. Saw a set off a 08 I think that were going cheap.
