2009 zx 14 3500 mi has pc5 auto tune akropovic evolution full exhaust

runs fine temp gauge hits 3 bars then hesitates idle to 4000 then runs
it actually sounds like a cylinder or 2 cutting out.Or is it fuel No codes displayed flies are in.Bike ran fine for 1200 miles Ive owned it
Anyone have similar problem?

Fogot to mention put 3 gals of VP 100 octane from gas station pump

Mine farts at very small throttle opennings. I notice it in second gear because that is probably the only gear where I am on the throttle very light. Usually does it when I shift gently to second and just open the throttle a crack. I am pretty sure it is the autotune adjustment I did. Probably no fuel in the 2% column or perhaps way too much. Did you do a fueling adjustment recently? Also, there is an option to tune/cylinder with Autotune. Could be possible some cylinders had fuel adjusted out of whack. The engine reaching operating temp might trigger leaner fueling and if it is already lean, maybe there is no fuel?

My first thought is how are you keeping the fuel fresh on a bike
that only has 3500 miles in 7 years?

Are you draining after each use, adding stabilizer?

Sounds like it's possibly gummed up.

How long was the last tank of fuel sitting?

SEAFOAM TO THE RESCUE!

That or injector cleaner. Bike seems to run smoother. I ran thru a 6oz bottle. 2oz @ 5.8gal... If anything it didn't hurt it.

I purchased 1.5 years ago with 2200 miles from a 75 year old lawyer.Doubt he matained fuel I winter.Sat when it was acting up stopped at napa and bought lucas extra strength injector cleaner added on the spot.drove another 30 miles added another 2 gal Sunoco 93 parked it. Today Monday went out for half hour got up to temp let fan kick on no issues.Clogged injector?PCV? Yes rook I added autotune after install dyno jet tuned my bike from 3000 mi away I granted them entry to laptop pluged into running bike 1200 mi ago Maybe ill call them again .Really want to adjust myself without detuning. between autotune PCV and mapswitch etc....

There is no pvc type system. If the bike ran better than Sat and it was that fast a clean of the injectors come Monday, chemical reaction?
A. Save map.
B. Manually remove all cell numbers on the first left two columns.
C. Install map change. That's idle area and let the stock numbers clean that up? Or did they clean those cells over the phone?

yeah, save our map anytime you let DJ do an interactive session. they tossed mine too. lucky i have it on CD.
But DJ is always the best place to turn when you have any questions. I'm not saying "don't ask around" but i've foud DJ's advice to be the best when it comes to their products. Very few people are messing with them anymore with most being happy with a flash. I would ask them to do another ineractive and see if something is amiss with your settings. I never had them f up my bike and they were in my computer 3 times now.

running terrible idle to 4 k again really need to resolve this on my own.could plugs be fouled at 3500 miles?
Bike ran fine Then shortly after VP 100 octane from pump started running bad, Loosened varnish and clogged injecto maybe?

I would suspect the gas was bad first. Higher octane not agreeing with the motor second. Put some regular in to balance it out. If not better give it a dose of Seafoam. Otherwise, drain it and fill with some 90 octane.

VP? ... In my world, I pour out race gas from the carbs, tank, injectors, fuel pump, is the day I poured it in. Let it sit, bad boy!

Toss the plugs. But is there still race gas? I'm not going to argue if it was race pump gas vs plain vanilla pump gas. You have no argument we have a bad running bike and now you bring forward more info. Why wasn't that the beginning of the thread?

Run carp out of the old plugs, take a ride and drain the tank out more. Run the injector cleaner for grins so you don't ruin the new plugs. Deal with the sputter unless it cleans out on some abandon road to redline.

It may be your injectors or you could have a bad ground with your pcv.

I don't know about that, Will. Say the pc was running all this time and usually the pc is bulletproof on most that have them running on their bikes, say. Starts right up, runs the rpm limit. I don't see a ground problem. Now comes the VP into the picture. You figure they use close to the same chemical makeup as the more higher rated; you'd think? So that more or less is to me, a chemical reaction of say that crap laying on the bottom of a caliper, not having the oil changed enough? That more or less locks the quad ring with it settling under the rubber and in its groove to push up on the piston and lock it. That kind of chemRe.

Usually the pc is a no run, rather than plugs misfiring... if the OP can determine that rather than the pc acting up. And since you are guessing back and forth, I'd more agree on the injector side than the pc side. That's where the chemRe comes back in play and using the cleaner at the nozzle holes, it may have built up there on the dry side of the holes. You know, when the vale is open on a dead engine, that's open to atmosphere in a faster evap. That could chemically dry that fast, crystallize that fast and close off the hole even just a hairline or a pie cut like a mountain ridge. Now act the incredible shrinking man, look at the circle, see how much square is in the micro; it closed that circle down. How much did not have time to take that space up and bleed out that pie cut.

So the less fuel the less flame front the hit and miss = Fire.

Make sense in the chemRe dept? ... IF it was the VP + injector + plugs?

Bike starts right up and idles? Yes = Not plugs per say.
