RANT! Cannot get the sssttuudddeeerrr to go away

[dkaar]

It is so frustrating...I love everything about this bike but the hiccup. I cannot get rid of it. If anything it is getting worse with the colder outside air temps. I have done the breather re-route and have the open airbox mod. I still have the stock ECM and exhaust. It has done this ever since I bought the bike when it was stock. Mine does it from 1800 rpms up to 3300 rmps.

in every gear or just first?

A good tune can take out a majority of the studdering.

Try plugs. And tune it asap.

Good luck and let us know the results.

Adjust your values to dissable you o2 sensor. Worked like a charm for me.

 

[dkaar]

I did new plugs (NGK Iridium's) and Magnecor wires less than 100 miles ago. They are gapped properly too. I probably need a good tune, no doubt. I have no idea how to adjust my values to disable o2. I am waiting for my ECMspy cable to come. Would appreciate more info on that though. Oh, and yes it is in every gear.

Just to put it out there, maybe a simple fix cause I did it myself...On the reroute, The hose might be pinched going through the frame.

What's it like above 3300?

Why would you have the revs so low? 1800 is pretty close to stalling.

 

[brightbuell]

Hey Otopuss can you help this guy?

 

[BKKBuell]

Try as well the K&N, my XB9 improved almost to zero... But the final result, I have been told, will come with ECM remapping. Even with race ECM (I tried recently) the hiccup remains a bit...

 

[dkaar]

I guess the 1800 was more of a guess. I run it in 3rd gear at 35 mph...maybe that is closer to 2200 rpm??? Above 3300 it runs fine as far as I know.

What year bike?

 

[dkaar]

2007 XB12. Did not find a kink in the reroute either.

Do a TPS reset. It's probably way out.

You will need ECMspy and a link cable to your laptop.

1) don't do airbox mods if you have a stock ecm.
2) don't do light performance mods without tps reset & learn-in.
3) don't do performance mods without ecm tune.

 

[dkaar]

The airbox mod made no change in the hiccup, been the same since stock. Cable is on the way to do a tps reset and tune
