Flaming out, cough stalls and false neutrals, 14 250r

[rabskyline]

Bike was busting my brain today with it's cough stalls and flame outs.
Also had a fair few false neutrals.

I wonder how much is to do with motul 7100 oil and the fact that the bike only has 200 miles on it so far.

I didn't notice it flaming out this much last ride.

Anyone else get it on their 13/14 bike ?

Rabs.
Not so much stalls -
For what it's worth I reckon my bike ran better when i first got it and before I removed the screen in the airbox It was picking up the front wheel under hard acceleration .
On the last ride - like yours I removed that end piece in the exhaust and I reckon it ran rougher and had possibly less power.

Noticed it looks fairly black around end of exhaust

I am going to put screen back in and end piece in exhaust

My pipe is clean and under throtte, it pulls hard absolutely rips mid to top.
Just on hills today it flamed out and cough stalled a lot.
We did camira and fridge hill but only flamed out on snotty shit.
Really annoying.

Cos new 300klms ??

Ps mine was.setup.jetted by mpe at pre delivery.

Maybe filter is dirty. ?

...absolutely rips mid to top...

Yep.
With the DB Killer removed you get a little more mid-top but at the expense of some bottom end... hence the stalling.
Dealers usually load "full power" map which works best with uncorked intake and standard muffler with DB Killer installed.

Another thing to check is your idle. 34 clicks out is standard but go a few more till the engine loosens up a bit with more KMs on it.

If you want a bit more go... get a TC250 slip on and open pipe map loaded. It'll stall less with this set-up.

When I quizzed Paul at MPE - he didn't know about an "open pipe" map
he just though there was two - as they came and a de restricted version

Ive also quizzed Brisbane motorcyles and they can no longer get access to on line data base now that PFG have lost distributorship .

Full throttle would be able to do open pipe map - Id say


I swear I think mine did work better with that mesh screen in though

MPEs Italian Husky specialist Casey is no longer there.
They looked at me like I had leprosy last time is was in there with my TE449....
Vote with your feet.
I'd run with Full Throttle if you can, they have been nothing but polite & helpful on the phone.

Unless you get Kurt, full throttle are as much use as a chocolate fireguard.
Been there, bad experience, went to see a bike, was supposed to be mint,they had taken bark busters off, bash plate off, rad guard off.....excuse, "people remove them so they don't damage them in the bush" (they were in the net pictures) ...I was like wtf ?? Total clown.
Anyway,
Bike was setup by Corey, Leo vince race map and fully uncorked,goes really really well otherwise.
That's what I was told and it's got more snap everywhere compared to Ash's bike IMHO, certainly much more responsive snapping the throttle.


Ride was pretty gnarly at the weekend, bike and clutch copped a floggin' at bits (read, rope skull dragging bikes up hills impossible to walk )

Yes your bike seem more powerful than mine but still worth trying putting that db killer back in for even more response down low and no stalling

Shoulda seen the looks I got in the Glassy with the Shercy ding ding... it was like this:

I had a brainwave(not often ) ...I over oiled my air filter last week, absolutely drowned it, so much that it was running down swing arm onto floor (yes, idiot) .
I removed and squeezed lots out but I suspect it still may have had too much in it.

I'll clean it out and redo it.
I'll also do an oil change onto new shell helix ultra, see if that sorts false neutrals, those are fairly new to the bike, might have been me somewhat but not claiming all of them.

Just an FYI. My womans 250r was gutless when we first got it. Was like a Crf230. Loosened up after 100kms but kept getting better till about 700kms

It's not gutless, goes like a cut snake even when new !
Got 350 or something on it now, ..

Ok, so took air filter out, it was still saturated with oil, that's a stupid school boy error, way way too much oil on it.

Feel like a twat as I knew it was over oiled but never cleaned and re oiled it when I should have..

Hope that's that cleared up and that the oil change is what's needed on the box.

Just check the idle screw is set right... 34+ clicks out

Yeah, Its actually a bit more, I wound it out (anti clockwise) more to compensate during the ride. It didn't really work, that's how I knew I had other drama.

Its funny that the 250 seems to stall more than the 310. Maybe just more engine weight spinning around.

Dunno, my wr250f never cough stalled, my wr450f did and would almost catapult my tartan arse over the bars !

On mine I separated the generator wires from the bundle.

Have you looked at the TPS sensor readings. I have found that on most bikes with a flame out issue that the TPS is set incorrectly.
Example....If you are getting say 7volt reading with the throttle closed, see if increasing that voltage to 8 volts by rotating the TPS a couple of degrees changes or cures the flame out issue. I have done this on may bikes to cure the flam out issue.

Rabs, check the injector****************************************! and anything related to fuel pump and fuel filter stuff, primarily the injector.

My TXC310R was basically doing the same. hard on gas ride hard and fast not notice too much, tight technical, brake check corners and rapid throttle movements from closed to open pop and cough stalls, always seemed like a lean spot, I was truning my idle knob around to try to compensate....no joy.
I was even adjusting myself to the issue, just thinking it was down to my technique... then ZipTy pulled my injector and had it tested - it failed for flow and the spray pattern was crap, they installed a refreshed one and all the weird ball breaking and me cursing issues are solved.
and of course be sure of all the other stuff, good fuel, fresh plug, good airfilter, and a good FI map to match your setup. PS after the injector was dialed in I went back to the OEM idle spot (I forget how many turns out from the book) and all was perfect. New owner is very happy with bike, no stalls no overheating, starts and runs great.

Mapping is too lean on entry point of the map on the MY13-14 250/310s when using modified exhaust. Powercommander is the only real fix for that issue.
