I will suggest that the amount contained in the oem oil filter cavity will vary between 2 - 4 ounces depending upon BDC vs TDC of the rod pin and parked on the side stand. I estimate the oil filter cavity to hold about 8 ounces total.
When parked on a center stand with oem filter cavity, the contained volume will be zero when crank stops near BDC, because of the few thousands clearance between filter cap & clutch cover bore. Of course dependant on tempurature and time parked.
When crank stops near TDC and parked on center stand the cavity may retain 4 - 6 ounces of oil.
If I Recall Correctly.
PS, I recon that I've always over-estimated the oil filter cavity capacity then. But then the Newer models have a smaller diameter cavity than the older models, which was part of what spurred me to modify the inlet. Remember the 1990 vs 2006 pic?
Modify at "YOUR OWN RISK"!
