Help......Overheating after replacing thermostat, hoses, & cap

Here is where I’m at with my VFR.

I took it for a ride today after slowly filling the antifreeze and massaging all the hose I could get my hands on to give a squeeze. I let the bike warm up to about 125 degrees to burp the system and check the level and top it off before I take it out. It was 89 degrees out today during my ride.

I rode the bike for about 15 miles very gentle on the back roads. I stayed within 55 to 65 mph. I kept a good eye on the temp for most of the ride. I did do a couple of strong pulls just to see how much the temp would rise and cool back down.

The temp bounced around 150 to 165, which seemed like it never opened the thermostat. Once I made a couple of stops at stops signs the temp got to 170 then came back down to 160 while riding. When I came to the last mile before getting home the temp went up to 190 then climbed up to 220 before stopping to cruise it down my dirt road very slowly. I thought for sure the temp was going to climb to overheating levels. What happened next had me shocked as I was very slowly cruising down my road the temp fell sharply and quickly back down to 190 by the time I pull into my driveway. I figured the fan kicked on and cooled it down quickly. I was tickled pink to see that. I still want to continue to ride the bike around kind of close to the house to see if the bike does any more over heating before I take it on the long trip to work.

I put about 84 oz of Honda antifreeze in the cooling system, but filled the reservoir between the upper and lower lines. When the bike got home the reservoir was almost full then as it cooled it pulled coolant back into the bike until the reservoir was down to the lower line. I imagine that filled the system back to full. I’m going to fill the reservoir back up to in between the 2 lines before the next ride.

With this info I have provided does anyone think that I blew a head gasket with the high temps it was hitting before I went through all the work to pull the thermostat and check the hoses?

I do believe my overheating issues was air in the system. Thanks to everyone here I have been able to get the motivation to keep working at it to get it back to reliable condition.

With more local rides I will know how well everything is functioning.
