The weekend of racing at Circuit of the Americas in Austin, Texas was pretty much as expected. We watched the bikes scream around the road racing course and walked through the vendor areas in between sessions, shopping and people watching. I’ve been involved in motorcycle road racing both as a racer and crew chief at the club level in the past. I’ve been attending international level races – World Superbike and Moto GP for a few decades.

Donna and I went to our first Moto GP together in 2006. We were newly married and she had a freshly minted motorcycle license when we loaded up our bikes with our gear and rode from our home in Mesa, Arizona to Monterey, California for the Moto GP event at Laguna Seca. We made this an annual exercise and Donna became used to traveling light with two weeks worth of clothing in her saddlebags.

When we moved to Michigan, the USA Moto GP event changed venues and moved to Indianapolis, Indiana. Perfect. We rode from Rochester Hills, Michigan to Indianapolis to attend. We made our last trek to watch Moto GP in 2012 – so this is our first event in six years. As always, we had a good time. I’m more into the racing than Donna, but she supports me and I think she likes the people watching as much as the racing.

We had great seats with a view of the back straight where the Moto GP bikes were hitting speeds over 200 mph before braking hard to enter turn 12 in first gear at about 40-50 mph. Then they had a series of 180-degree turns through 13, 14 and 15 – the slowest corner – before accelerating right in front of us to turn 16. We also had a big screen monitor by our grandstand to see the action on the rest of the course.

Donna and her new friend – even cowgirls are bigger in Texas

After the last race Sunday afternoon, people started packing up and many of the RVs in the dry camping area pulled out. I’m sure many people took a long weekend from their workaday lives and had to head back to reality. We had a quiet night. I grilled chicken thigh quarters that Donna marinated in something called pretty chicken marinade sauce.

This morning we packed up. I talked to the folks at Fleet Maintenance of Texas on the phone about our hydraulic issue. We spent the weekend here with the jacks up – I got as level as I could with pads under the tires – and only one bedroom slide out. I didn’t dare open the living room slide for fear of not being able to retract it if I got it open. The living room slide still wasn’t in the fully closed position – it was nearly an inch open and wouldn’t close any further. After we packed up and were ready to leave, I tried to close the slide again to no avail.

We made the drive across Austin to Fleet Maintenance of Texas. Cameron helped us there. When I described the issue, he came up with the same thought I had three weeks ago. He said he thought it was a fluid level problem or maybe air in the system.

I removed the cover from the compartment housing the HWH hydraulic reservoir and pump system. I was surprised to find the compartment wet with hydraulic fluid and crud. Here’s the thing – I open this compartment every time I get fuel, I store my Biobor JF fuel treatment there. It wasn’t wet when I fueled up on Thursday.  After 15 minutes or so, Cameron came out with one the techs – his name escapes me – to look at it. He checked the fluid level, then told me to run the jacks down so he could look for leaks in the manifold and lines.

I ran the front jacks down. The pump sounded normal – it had a different pitch when the problem started. The jacks hit the pavement and lifted the front of the coach. What? Next I tried closing the living room slide. It popped right in and closed tight.

Have you ever had a toothache that disappeared once you were at the dentist? That’s how I felt. I couldn’t believe it, everything seemed to be working. The tech told me he didn’t see any signs of leakage. He asked me to lower all of the jacks, then operate all of the slides. Everything worked like magic.

I came back outside scratching my head. We talked it over. The tech said he thought I must have had air trapped in the hydraulic fluid – remember when I said that back in Benson? He told me that the air in the fluid is dispersed when the pump cavitates and millions of tiny bubbles are in the fluid making it milky or almost frothy. Of course the air is compressible, so you cannot reach maximum hydraulic pressure. The tiny bubbles slowly coalesce into larger bubbles which then find their way to the high points in the system. The highest point is the reservoir, but to get there the bubbles have to make their way through junctions and valves.

He theorized that the air finally made its way through the valves as we were driving to the shop and burped into the reservoir, causing some fluid to blow through the cap vent, thus the fluid we found in the compartment.

I had to agree with him as I can’t think of a better explanation. Cameron voided my repair order and didn’t charge for checking the system. Nice! I’ll need to thoroughly clean the hydraulic compartment.

We drove from the shop to a nearby Walmart to regroup. I hadn’t made any reservations thinking I needed to know what our situation would be once we hit the shop. Donna walked to a pizza place at the other end of the shopping plaza while I looked at options.

We decided to head east to the Gulf Coast. I found a nice RV park in Aransas Pass and booked a week. This will give us a chance to visit with my middle daughter Jamie. We’d like to explore a bit – we stayed near here at Copano Bay outside of Rockport two years ago.

We had a quick lunch – the pizza was very good! Then we made the four-hour drive to Aransas Pass and arrived around 4:40pm. We were escorted to our site where we dropped the trailer and quickly set up in a full hook-up site – jacks down and level, slides out!

The weather forecast for the coming week looks promising – high 70s to low 80s. Not showing much in the way of precipitation, but I know a thunderstorm can kick up around here quickly at this time of year.
