motor making funny noise
ok this is what i got guys and gals when im rinding my bike (08 low rider) if im in 4,5,6 gear and i put a load on the motor ie going up a hill or something and i put the hammer down i hear this strange noise come from under the gas tank in the best way i can descibe it is it sounds like a special effect sound from a hollywood move for a lazer gun shooting idk if is something in the motor or the pipes i pulled the plugs and they look white to me so maybe it's running a little lean im not really sure whats going on what doo you guys think

maybe pinging? I had what seems to be a similar sound (kinda a cross between a starwars blaster and someone shaking a can of gravel) sound when I really cracked the throttle. Turned out the motor was pinging at the top of the rev range.

The white plugs are normal for a EFI motor with the original tune. I'm assuming that is what you have, and mine, a '10 FXDC, has white plugs too.
You could be describing a ping from the use of lower than required octane fuel, and the load condition under which you say it occurs would fit that profile.
Personally I'm not a big fan of iXED's. To me they just default the bike to a too rich condition and negate all of the sophistication built into the Delphi EFI.

sophistication built into the Delphi EFI... the sophistication of running lean?
I installed a xied, bike runs cooler, no more pinging, engine runs better than ever, plugs look fine.

Back to our normal viewing...OP, based on the limited info so far, sounds like your engine is pinging, which in and of itself is not uncommon in stock engine with stock pipes, AC, and EFI. That said, (and I'll freely admit to being no expert here) it is something you want to avoid for any extended time by either a) not riding so hard, or
b) using Xied's or some other fuel management system, or
c) do a proper Stage one upgrade with pipes, AC and Fuel management....

XEID's do not negate the sophistication, nor default the delphi EFI. It tricks it into adding more fuel but other then that works exactly the same as without.

yes some more info from me proably would have help sorry guys the bike has stage 1 k&n air filter with power commander and a set of aftermarket pipe that look like stock one idk the brand all of this was on the bike when i bought it before i ever put one mile on it i took the bike to my local harley dealer and they went threw the hole bike and said all was well they put it on the dyno too 71 hp's at the wheel and 80 something foot pounds torque and yes this is a new thing that just started happening so what is the min octane rating for this motor
krazy8s it sounds like we have/had similer problem maybe the motor is pinging but i don't think im hitting the rev limiter this all happens around 2000 to 3000ish rpm's

was thinking the same thing. If the Delphi is sophisticated, i'd like to know how to tap into that 'cause out of the box it's rubbish.

Seems a bit weird to me that you are only getting 71/80 out of a stage 1.... again, I am no expert, but these numbers seem only marginally better than stock. Might be an idea to contact Jamie at fuel moto to get his opinion on it. Still sounds like pinging to me, but if a stage one is done and this just came up then there could be a whole different set of issues going on here. It could be as simple as the PC needing to be better mapped, or something entirely different. Over to those who have vastly more knowledge than i do.....
