    Ok here is my problem , i just got my bike back from the shop today 2007 883 ,,,i had the 1200 conversion done ,,,,bike runs great very strong ,,,but when i let off the throttle it pops like backfiring alot ? guy at the shop said it needs new pipes that doesn't have the cross over tube on the bottom like mine ,,,but i just put those pipes on there a few months ago with all new gaskets...didn't do that until they worked on it ,,,any help would be great

    Did they do any tuning for the 1200 up grade" Or could have a exhaust leak?

    they say they had it on a dyno ,,, i think it is something in the tuning it never ever done that before ,, so i think i got ripped off they didnt even give me the package or the disk for the power commander they put on it ,,,and trust me first thing in the morning i am taking it back
