Round 4 – Preparation
I am my own harshest critic. At the end of every race weekend, I look back at what I did and ask myself “did I get everything out of myself and my bike”? Invariably, there’s a laundry list of things I could have done differently. In large part, race reports are a way for me to gather my thoughts and make sure I remember the lessons I’ve learned and improve my program.
After struggling with getting the bike to exit out of certain corners during the last 2 rounds at Infineon, Jason and I planned to do everything possible to get the bikes dialed in for Thunderhill. Phil at Aftershocks went through and refreshed both shocks and forks and improved some of the valving. A test day with Z2 at Thunderhill on June 4th gave us a chance to check it all out and try to improve our corner exit issues. I came away with a slightly better bike, but needed a different rear spring to get the good rear traction Jason was getting from his bike. I’d considered buying more spring sizes at the beginning of the season but just let that concept slide. Preparation lesson #1.
I showed up at Friday’s open test day at Thunderhill with 2 new springs. After Phil showed up and we got the spring swapped out, my drive traction was way better. We spent the rest of the day fiddling with the knobs to get the rear end tuned so it would stay in place mid-corner and get the chassis re-balanced. Mid-afternoon, I felt like we were converging on a good setup, but in chasing Somy Hoffman for a few laps, I realized just how far off the pace we were in a few areas. Trying to pick it up, I found myself fighting to get the bike to finish turns. As soon as I’d open the throttle, the front end would track wide, and I’d end up pulling hard on the inside bar to keep it in line. We finished the day with some significant geometry changes, but no major improvement. Low 1:57’s were all we managed.
In Saturday practice, with Phil back at the shop, his helper Jason Hauns took over as head suspension fiddler. Now that I was really paying attention to this turn finishing issue, it was starting to become clear that the front end just wasn’t behaving. Our rear spring change had changed the overall balance of the bike. We had lots of traction, but the front wasn’t playing well with the back. After a few calls to Phil, and trying multiple adjustments, we ended the day concluding I probably needed different fork springs, and made some rear end damping adjustments that somewhat compensated for the issues up front. Preparation lesson #1 (again). Know exactly what is in both ends of the bike, and bring other springs.
Sunday morning’s 1 practice session was spent focusing on how to ride around the issues and avoid getting eaten up too badly in 1,2,3,4,6 and 8. The bike behaved pretty well in 11-15, except for a somewhat unpredictable drift on the gas out of 8, 13 and 15. I’d have to give away some room out there to make sure I stayed on track. With only a 1:56 chasing Liko on race gas, I knew we were pretty short of where I was hoping to be for the races.
Race 1: 600 Production
Gridded in 7th, I had a pretty good outside line heading into turn 1. I got away well, but I gave away positions in 1, 2, and 3. The fresh SC1 rear was sticking well though, and helped compensate for my tracking issues. A red flag on lap 2 gave me a second shot at the start with my new traction confidence.

I held 5th until turn 9 when Somy Hoffman came by. With Tinagero and Hoffman both unable to get around Berto, I had a lap to size up the situation, and passed both of them into 14. Closing down on Berto, I outdrove him out of 8, but wussed out on the brakes, and couldn’t complete the pass in 9. He held the outside line and gapped me down the hill. That was my shot to get by and head after Liko and I didn’t take it. Robert came by into 14, and I found myself battling both of them for the rest of the race, with Somy joining the party as well. I was strong between 11 and 15, but was inconsistent fighting the bike around the rest of the track. We passed the checkers in a pretty close group, with me in 6th. Best laptime: 1:54.3
Race 2: 600 Superbike
As I rolled out to the hot pits to warm up the tires a minute before the warm up lap, I noticed my left clipon had moved towards me a bit, presumably during the last race. I banged the bar back out to its normal marked position and headed out on the warmup lap. I’d need to pay close attention to any movement in the race. I knew I was pulling really hard on the inside bar in turn 8 to get the bike to finish the turn, and had no desire to have a moment in that area of the track.
Gridded 5th (inside of the 2nd row). My start was ok, but with the tighter turn around the corner, Berto came back by, and I found myself in 4th, and held that for the first few corners. After another half-assed pass attempt into 10, I drove past Berto out of 13 and set off after Liko. Hell yeah. 3rd place and charging. Let’s do this. No such luck. As I came through 8 on the second lap, the front end gave me a big smooth slide. It came back together ok, but it was far from inspiring. As I came through the next few corners, I got a very not-sticky feeling from the front end. For all my other complaints about the bike this weekend, the front hadn’t been actually sliding in the corners. This was something new and weird. Combined with the rear tire starting to go off due to our aggressive compression settings in the rear, the bike was getting more out of shape every lap.
Sebastiao and Santa Coloma passed me on lap 3, and Berto came by in a tight move into 3 on lap 4. Coming through 5a, he threw up a hand in apology, but his hand came back down on his kill switch! Barely avoiding hitting him, I drive by, only to be passed by him around the outside of 1 on the next lap. With my only goal to bring home the strangely handling bike, Eccleston and my teammate Jason come by me on the 2nd to last lap, with Iturrioz joining them in the last lap. To my dismay, as they came through 8, I watched Jason go down, with his bike hitting the berm and going airborne with a few flips. Cursing, I looked back, confirmed the big gap behind me and brought it home in 9th, with a best laptime of 1:54.8.
As I pulled in, I asked the guys to check tire pressures to see if there was something out of whack with the front. Nope. Spot on. The rear was a bit high, and was tearing, but nothing too crazy. Later, as we packed up for the day, we notice that the left fork had slid up in the triples by 6mm. I’m not sure whether that happened during the turn 8 slide moment, or at the end of race 1. Either way, it explained the front end sliding issues. Preparation lesson #2. Go over anything adjusted on the bike twice. Then do it again.
I left the track with a deep sense of unfinished business. The bike could have been much better if I’d planned better, had other springs on hand and pushed the pace sooner in practice to reveal the issues. On the other hand, I’m not sure if we would have been able to clearly identify issues and keep it on 2 wheels pushing any sooner.
The front end is already in Phil’s capable hands, and we should have a much better bike (and other spring options) soon. Can’t wait to give it another go next round.
Thanks Z2 for your support this weekend, Phil for all the suspension efforts, Sam and Kyle for helping in the pits, and Joe for the schweet pics!
