Thanks a lot!

I found that the stalling problem is most probably the low fuel (I think half a tank is "low", but not 100% sure)... I've been refueling after every ride and it hasn't stalled since. About the gas, I also found out that mine starts with some throttle and then I had to hold the revs a bit high, so it doesn't stall.
About the idle, I'm waiting for a new temp sensor and a new intake manifold. I'll report back when we replace them.
We'll do a valve and cam check, but not sure when. I guess when the snow falls

My pump was replaced and it's mounted securely on a different mount so it isn't moving , sounds good both cold and hot so that part is fine . I ordered the JD Jetting Power Surge 6X tuner to hopefully cure it . I have a wideband meter for jetting other bikes so I'll be able to tune it fairly good , hopefully that cures it . Would like to get an iBeat diagnostic to reset the TPS , I'm sure it isn't set perfect anymore and no way to do it any other way as far as I know.

I think besides the fuel pump moving and needing to be secured if your bike is doing the hot stalling and idling flameouts the only way to "fix" it is with a tuner to do a better job of getting the proper air/fuel mixture down low . A slow twist throttle is also helpful so it can keep up better and you have better control .

Okay, guys, so I replaced the water temp sensor with the upgraded one and changed the intake manifold. It still idles very rough(in my country its now getting pretty cold if that matters). I forgot to mention that the fuel level sensor was broken off and I removed it, but I don't think this cause the problem.
It still backfires a lot and stalls when hot, but now I can start it right away (before I couldn't start it) as long as the tank is full. When I start it and give it a little gas it stalls immediately. It has very inconsistent behavior - sometimes it stalls, sometimes not. I think it only does it when it's stationary at a light and gets a bit hot.

Next I'm thinking of a valve and cam check and if they don't work - a JD Tuner or PCV or some other kind of witchcraft. I'll report back.

PS: IBeat showed high water temp error.

IIRC you can set the fuel trims with the Ibeat. Do you recall what the values were?

I'm not sure what fuel trims are. If they are the 3 percentage settings for low/mid/top throttle, I think I can't do anything with them(the arrows are disabled). They are 100% 100% 100%. And I think I read somewhere that it's either impossible to set them for this model, or you have to get the bike really hot for them to unlock. I'm not sure we've tried getting it hot, but by default the up/down arrows are disabled.

This is THE Ibeat thread, take a peek. Setting fuel is in the very first post.

I installed the JDJetting piggyback controller last week and now mine is running good , no more stalling and the throttle is crisp. I did have to do a little tweeking with the values , mostly adding fuel to both the idle ,low , mid and "accel pump" feature. Lean condition is main issue with these.

I honestly can't see how any of the previous owners ran the bike for so many miles with it like that unless one of them did have a controller and removed it, but I saw no wear spots or rub marks,or ziptie wear lines ect.. that one had been on the bike so I don't think they did. Could tell the guy I bought it from was kind of a idiot.

The idle screw does need to be turned "just so" , it doesn't seem to adjust idle up/down as much as a person would think for how much he turns it , but it also helped stop the flameouts even after the tuner was added. Idle is set to 1900-2000k.

 

[jjktmrider]

So did the new temperature sensor fix any of the erratic idle issues ?

Mine is still being annoying when hot even though the tuner fixed 90% of the flameouts and it runs crisper and cleaner I still can't shut it off once hot and then restart without needing a little throttle then I fight the thing from stalling , light popping and stumbling . If I start cold and don't shut it off it runs pretty good just when I shut it off and restart when its hot that it seems to reset something in the ECU that makes it run like crap till I shut it down and let it fully cool down. I'm wondering if the temp sensor is messing up when hot and causing the ecu to change and the expensive tuner can't alter it back to "normal" .

I'm ordering one just to make sure I guess , something has got to change or I'm out of the Husky game till I can afford the KTM versions.

I forgot to post, sorry. I'm afraid nothing changed. I changed the intake manifold and the temp sensor. Next thing to check is to see if the resistor is placed correctly(or placed at all) and the wiring. After that - a valve and cam checks. If nothing works I'm thinking of ordering a tuner from JDJetting. I'll fix the damn thing.

 

[jjktmrider]

The JDjetting tuner fixed some of the regular flameouts on mine and cleared up the running for the most part , however it did nothing to this warm restart issue , even after running it for a while when it's getting hot it starts to flameout when first stopped and fussy with how fast I can throttle up from idle , I have to constantly feather the throttle. Mid to topend rpm she screams.

I personally am ready to sell the damn thing or replace everything that has to do with the efi and go to a carb, where it can actually be fixed. Shame , I like the power of this beast.

You might want to check out where your TPS is set at
that is usually where the problem is
The Mikuni EFI is great
mine works flawless even after 14000 miles
Check your TPS and go from there.

It's the first thing I did. I think it was on 101.2. Sadly nothing changed.

 

[jjktmrider]

I haven't tried it with mine , I don't have the Ibeat for resetting it . I think there is a way to do it without but haven't read up on it. There is that mod of taking the butterfly roller out so the ecu can't control it , I was thinking of trying that , can always put it back if it does nothing.

Checkout millenium7 post. This is how I made it and it works.

Dude it is 100.2 that is the number
That could be your problem
when you set it to that it will idle at 1900 to2100

Thanks a lot for the link, but it was 100.2 - I remember now when you said it. Sadly I can't connect it to Ibeat it now, because I lend the cable to a friend of mine. When I do something else on the bike I'll update the thread with the results.
