Well, cleared the Historical codes, rode it last week but didnt have a chance to check it, just checked it, no new codes, thing idles but it sounds like its missing on 1 cylinder then catches, idles for a tad, then drops the cylinder, then catches... Only happens on idle... Was hoping to see something but doesnt look like it...

Heres the Gauges view on Protune with it idling, if you rev it a tad, the Target Closed Loop goes into red..


Heres a better vid of it missing on idle... Curtis was helping me out, but I thought Id share also..

The first startup is good... The 2nd Startup at the 40 sec mark is where you can really hear it missing...

That is odd. Only happening at idle?

Couple of us have had issues with clogged injectors. We ended up pulling and cleaning them and replacing the in-tank filter.

I have also had to replace plug wires.

J...

Only happening at idle... The off idle stumble is so bad, if you dont ease into the throttle it almost chokes itself out and dies, even after running it for a 20 mile run and everything is warmed up, still the same issue. When you are at speed, 2k rpm and above, throttle response is normal, rev's right up, no issue, just like downshifting, pull in the clutch, blip the throttle, drop a gear, and let the clutch out, no issue.. But if you pull the clutch and hold it, let the rpm's drop too much then try to blip the throttle, it stumbles. Even taking off from a stop, if you dont give it enough throttle, it acts like its going to stall, and misses. Dont get me wrong, Im sure it doesnt take much to stall one of these motors, but with my experience, when your rolling the throttle and feathering the clutch, these V-Twins should have quite a bit of lugging power, this one wont lug, even at speed it doesnt like to lug, very choppy if you try to lug it 2k and under... Which just doesnt seem right...

Ill get another vid of it running and show the cut out off idle, I know the Protune vid was only 8 sec, next vid Ill get it so you can actually see the major bog...
