No. The level did not even go down at all.
So, after pressure testing everything today I siphoned out the excess coolant in the expansion tank, started the bike up and burped it the best I could. Got a couple bubbles. Went for a ride, and I noticed bubbles were coming into the expansion tank from the vacuum tube almost non stop. Eventually the bubbles stopped, and the expansion tank at this point was close to empty.
After getting home, I topped off the expansion tank and put her back together. Btw the amount I removed from the expansion tank to get it back to normal levels was the exact amount that had to go back in to bring it to normal levels after my ride. Net zero change.
So somehow a bunch of air got into my system, which took up volume in my radiator/hoses, thus forcing the excess coolant into my expansion tank. Don't know how that happened.
Sadly, after going for another ride later today, the level is again way high, and after cooling off for a bit, none of it has been pulled into the radiator!! Mother.
Somehow air is getting into the system as I ride. Praying it's not coming from the combustion chamber.
