There *is* a trim adjustment on your ECU.

Whether it's got enough mojo to cure the issue.... well, it depends where it's set now.

should be set to factory afaik; it was rockin' the stock cans when i got it.  is the trim stock set to... say the "middle" (allowing for adjustment either way), or is it set to the "lean" position (allowing for a bunch of adjustment to richen the fuel, but none to go more lean)?

I've no idea where they set them at the factory.

They may have a nominal setting that all bikes go out with, or they may be tuned individually.

You can also ask around if someone has a similar setup with a PC. You can ask them to share it with you.

hmm, my shop is swearing that they can't do anything with my stock ECU.... he said he'll hook it up to the exhaust sniffer for about $50 though to see where it's at right now.  just seems weird that i wouldn't be able to have the ecu adjusted slightly to just dump a little more fuel...

he did say they would be happy to sell me a DP ECU for $1500 plus a couple hundred to tune it.  of course, they don't have any in stock.

but going back to what i was originally worried about...is there any real long term concerns or possibility of harm for running lean (enough for lots of popping)?  i've heard people say that if you run too lean the engine is operating at higher temps and can ultimately do stuff like burn up a piston.  any real truth there or is that just the worst of scenarios and the rarest of outcomes?

$1500?  :o

PC with a custom make is less than half of that.

Any updates McKraut? I've been following this thread, b/c the Mivv x-cones are doing the same popping to my '07 695.   It's been suggested, to unhook the 02 sensor, does anyone know if this is a remedy, or what problems could occur by doing so? thanks in advance.

no 02 sensor for me though....  but after calling back AMS (mostly to see if i couldn't find a different tech to talk to), he said i could always swing by and put it on the exhaust sniffer to see where it's at there.....  for $50 of course.  i guess i could do that, but it's just going to tell me what i already know....it's leaner than fat-free turkey hot dogs.  there, i just saved myself $50.

as to what if anything i'll do, i don't know.  the tech did go on to say that i shouldn't run into any long term problems really (re: burning up pistons or rings), if i'm not "revving the piss outta it".  which i don't...but i'm not exactly heartened by that.

still confused why he would say there's nothing to be done with the stock ECU trim-wise, when most people say differently.  just don't want to pay $100 for an hour of labor just to hear the same thing again "yeah, we really can't do anything with your ECU".

Ever since I installed the hi mounted Termis, got this issue...  ???

after feeling all the exhaust joints where leaks might be occurring, there doesn't seem to be any, but a tiny bit by the header pipe for the front cylinder.  i could jam it full of copper exhaust sealant, but it's not enough that i think it would make any difference at all.

does anyone have any experience with the Power Card that desmotimes sells?  i wonder if that's a reasonable alternative for my situation.

One way to find out...send  LT an email...by the description of it, if works even better than the PCIII...I let the dealer adjust once every so often...they cannot charge me...'guarantee issue' as they call it...

But once bike is running again, I'll decide if to buy DesmoTimes PC...And THEN I'll let you know...gimme till the endo of the year... :-\

Is a re-flash of your standard ECU to DP ECU spec an option? I know it is now for some bikes - S2r1k included - for about 500 bucks. Not sure about yours though... :-\

a reflash would be cool, but honestly $500 is way more than i'm willing to spend just to reduce popping on deceleration.  so, make the beast with two backs it, it'll just be my calling card then...and one more vehicle of loudness, so to speak.  the clutch and exhaust are already loud as shit, this will just add to the wave of sound that follows my bike.  maybe it'll help to scare cagers away from me in traffic even more... it sounds like gunfire sometimes.
