2011 TE 250 1st gear bog

[tbradbury]

I am having an issue with the lack of power in 1st gear. It seems to always bog. I have read many forums regarding this issue but can't seem to find an answer. I have a JD tuner that I have yet to mess with. Would the tuner be an answer to my problems? If this is the answer can you provide settings?

Thanks in advance!

The JD tuner will help a lot.

1st get the pike powered up by removing the O2 sensor.

Then adjust with I-beat or your JD tuner.

If that doesn't work then get the 12 hole injector and related CDI to go with it.

My 2010 TE250 works good with an I-beat adjustment.

Hi R Little,

Just a little off the subject, but could you tell me what a I-beat is? I've read it a lot on forum but have no idea what it is!

cheers

iBeat is the name for the Husqvarna ECU/FI tuning tool. It plugs into your bike and a computer and allows the user to adjust your fuel tuning setup.

And one of the site sponsors Semco sell a 'replica' of the iBeat for civilians

I have similar issues with my 2010. I understand the JD Tuner will help with the issue and can clean things up however after feedback on here and riding a 2012 I have elected the 12 port injector and ECU upgrade. The upgraded ECU not only updates the AFR but also changes the ignition timing allowing increased performance.

Turn the idle screw so it idles at 1950-2050 rpms, that'll help. I have a 2010 TE 250 and it idled from factory (once I derestricted) at 1400rpms. In power up mode, that's a little too low in my opinion and will catch up with ya in the woods if you don't clutch it a lot.

I have a JD-Tuner as well - it certainly helps, my bike is still in storage for Winter but in the coming weeks I'll take er out and try to post some settings if you haven't found any yourself. For the most part, I had best luck with the settings at 4-5 but the accelerator pump setting really low for some reason (like 1) ... strange on my model, the acceleration pump setting was too rich and help caused the 'low end bog' as well as the idle screw being too low for powered up mode.

Best of luck

I've tried both the JD Tuner and the upgraded ECU & 12 port injector and the latter is what you need, makes the bike perfect.
I did manage to improve the low end stumble/bog with the following settings on the JD tuner;

Green/Blue (idle) 5
Green (low) 5
Yellow (mid) 5
Red (high) 4.5
Yellow/Blue (transition) 3
Red/Blue (accelerator pump) 1

It was dropping the red/blue setting which improved the bog, never completely gone but much more ridable than before.
