Coolant level goes down, but oil level stays the same, but gets contaminated with coolant, it may be small amount as I measured the oil I toom out and it was the same I put in. The weeping hole at the bottom of the water pump is not leaking oil, but its clean as I cleaned it when I changed the water pump mechanical seal. I saw lots of white smoke for about 10 seconds once, and the bike did not do it again. I also saw some small amount of coolant dripping between the end of the head pipe where it meets the muffled, but it was only once. The level of coolant goes down very rapidly, about 8 ounces in 10 to 15 minutes, but no drips on the floor, and no dripps that I can see coming from anywhere.
A lot of your statement does not make any sense! To me.
Where is the 8 ounces of coolant disappearing from/and going to?
I'd think that there is at least room for 8 ounces in the coolant recovery bottle, above the full line? (If head gasket was leaking pressure, that is where the coolant would GO.)
I have a hard time imagining that 8 ounces of coolant can escape, and no spot on the floor, no rise in oil level. (If cylinder SLEEVE base 'o'-rings were leaking, oil level would rise.)
May I suggest that you only fill the engine with ONLY 2 Quarts of oil. And 'magic marker the window'. This will allow you to see any rise in oil level. Aeration of engine oil, (visible 'tiny bubbles', IS NORMAL) with cold oil.
I can only Strongly suggest that you check every hose clamp, at this time.
