Same as oem, somewhere between 0.002" to 0.0025", depending on how accurate your machine shop is....

i already relieved the bridge, i have 9 days till widowmaker and dont have it together yet. my crank seals and oil seals just came in tonite so i can have the thing ready to bolt in by this time tomorrow. i just got my swingarm back from being extended and it is nice! 65-3/4 " axle to axle fully extended. ill post pics when i have it all together. its at the last bore so i need it to just last 2 or three good hard runs, then it gets a glen'ed jug.
