so i finally bit the bullet, getting a 1200 conversion for my 883custom. getting the full screamin eagle pack, barrels, heads, heavy breather and supertuner, supplied and installed 3 grand even. they reckon it will take a week to get the bits in, then a full day in the workshop. i wouldve done it myself, but they are only chargin me $500 in labour, and it comes with a warranty, where it wouldnt have if id done it. worked plenty on cars, not too sure on bikes though. cant wait now.....
