As previous race reports noted, my 450cc VFR engine was parked a while ago because of concerns about the titanium rods. At least two other engines using rods by the same manufacturer had shown signs of gouging on the sides of the rod big end, and our external look (through the clutch cover) at the TI rods in my own engine seemed to indicate a similar issue occurring. Rather than risk destroying the engine, we parked it and I raced the last two races (Thunderhill and Buttonwillow) on the 400cc bike.
As a replacement for the titanium rods, Mike Norman at G-Force was able to convince Carillo to make some rods. Carillo had never made rods this small, but they are one of the premiere rod manufactures in the world, and Mike knew their quality would be top rate, even on a new design. The 450 motor was torn down and inspected while we waited for the new rods. Everything looked great, even, to our surprise, the titanium rods. There was no gouging on the sides of the rods, and they showed no bad signs otherwise. We considered maybe re-using them.
The Carillo rods arrived. After ogling over them for a bit, we weighed them. They were supposed to weight the same as stock, or a little less. Mike put a stock rod on the scale and zeroed it. Then he weighed the Carillo rod. It showed 22 grams over stock. The disappointment was pretty severe as it seemed that once again, we just received a box of useless parts.
Mike got on the phone with Carillo and immediately learned why Carillo is a world class company, and why the small shop that made our original rods is not. Carillo apologized profusely, said send them back right away and they would get it right or refund the money. On top of that, later conversations with Carillo led to some even better options, including the opportunity to try out two different designs that Carillo wants to make, and maybe even a titanium rod made by Carillo. More on that later when things are more solidified.
Now we were faced with leaving the 450 motor apart for several months waiting for the new rods, or re-assembling it with the old titanium rods. They looked fine, but they still concerned us regarding issues seen on the other engines. We decided it was reasonably safe to re-use the TI rods and put the motor back together. My motor had lasted a long time with no sign of issue, so we felt it would be OK. I would use it for the Vegas and Sears Point events, and then tear it down again when the Carillo rods were ready. I was pretty happy to have my 450 motor back.
Between my two bikes (the 400cc bike and the 450cc bike), I have only one set of carburetors setup in the NC30 HRC style (open airbox, HRC jet kit, etc.). I have another set, but there is something wrong with them, and I can't get them to tune right. While the 450cc motor was parked, the good HRC carbs were on the 400cc engine. But, those carbs were transferred back to the 450 engine, leaving me to use my spare stock RVF carbs once again on the 400cc engine. With little time to mess with it, I just installed the carbs, packed up and headed home to get ready for my trip. At least I had two operating motorcycle again.
Going all the way to Las Vegas for a race is pretty expensive and a little hard to justify. But, my wife's sister lives in Las Vegas, and it was a good excuse to visit family. So, I loaded up the Dodge Dakota Quad cab with all my race stuff in the back of the truck, the bikes on the trailer and the four of us in the cab. For a mid-sized four door truck, it handled the 7500 lbs of weight, two kids, wife and all our crap pretty comfortably. But, hey, that's why I bought it. We left Thursday afternoon and arrived in Vegas at about 3am. Thanks to my empeg MP3 player for providing unlimited tunes for the 9 hour trip (does your car stereo run Linux?). Long drives in my truck are the best time to listen to music, even if I couldn't crank it because the family was sleeping.
As stated above, instead of having practice all day on Saturday and racing on Sunday, this time, Practice was all day Friday with racing on Saturday and Sunday. Most of us had never seen the track at Las Vegas Motor Speedway (LVMS). On top of that, AFM was running the track backwards, so those few that had seen it had never run it in this directly. Needless to say, there were a lot of people going pretty slow at the start of practice. See the track map below for turn numbers as AFM labeled them.

Running in the opposite direction, the track was odd. The end of the front straight ended in an S bend. There wouldn't be much out braking into turn 1. Also, half the corners were decreasing radius, tight corners (turns 3, 5, 6, and 7). The fun factor was high, but passing sucked, especially as the pucker factor was pretty high for lots of people. I had to be on my toes as so many people couldn't figure out how to late apex the corners. Lines were all over the place. It got much better as the day wore on. It was clear passing opportunities would be slim.

By the end of the day Friday, my best time on the 400 was 1:41.4, and on the 450, it was a 1:37.7. Good references points, but I knew things would speed up in the races. I set a goal of 1:35 by the end of the weekend, a realistic goal provided I could get a clean track.
I had only one race on Saturday, Formula I. Plus, we had two practices in the morning. With a long gap between my practice and the race, I hoped I would get some time to visit some of the other motorcycle events of the weekend as there was so much going on. Transportation was the problem. It was too far to walk to the other events. I should have brought my kick stand for my race bike. I could have used it as a pit bike and rode to the other events.
It was pretty common to see someone ride over to our track on their lowered and extended drag race bike or other race bikes, or to see people driving around the facility in their NASCAR race cars. One NASCAR type car even pulled out of the facility and drove down the highway. Maybe he was headed to McDonalds for lunch. And I thought that stuff only happened in TV ads.
It seemed that about 1/3 the normal crowd showed up for the Vegas weekend (about 125-150 racers I estimate). In Formula I, the smaller grids were a good thing for me, being on an underpowered bike vs. the 600's and 750's. It's easier to pass the bigger bikes one at a time. There were 32 finishers (don't remember the number of starters), approximately 10 of which were "lightweight" bikes like SV650s and 400 fours.

It was the most fun I've had in Formula I all year. I was racing mostly with bikes of a similar power range as opposed to passing big bore bikes in the corners, only to be passed back on the straights. Normally, that's how Formula I goes for me. There was a proposal to create a "Lightweight" class in the AFM that would include the bikes from 450 Superbike, Formula 650 Twins, 250 Superbike, etc. I got a feeling for what that class would be like in the Vegas Formula I race. It would be great if the AFM could find a way to work it in. Maybe some day.
By race's end, my best time was 1:37.5 with a 15th place finish. Not the 1:36 I was hoping for on Saturday, but I was still figuring out the track. I knew what I had to do, but it's hard to make it happen consistently when the track is still new and I didn't totally trust the new pavement yet. Later that day, in 650 Twins, Jeff Tigert turned a 1:34 on his SV650. Clearly, he had the track figured out. But, he's a step ahead of the rest of us too.
With my day over, I did some minor work on the bikes, packed up and headed out for a night of visiting family, dinner, and a walk down the Vegas strip.
We started the day with two practices in the morning, followed by a long delay before my two races, which were back to back - 450 Superbike first, followed by Formula Pacific.

For myself, I always put the hammer down and turn some of my best lap times in morning practice on Sunday. Today was no exception, turning a 1:36.002 on regular pump gas, 1.5 seconds faster than Saturday. Now I knew a 1:35 was possible, and expected the intensity of the race, and the "go fast" gas would bring it out of me. Time to go racing.
We were gridded with Open Twins (as usual), with about 15 bikes in 450 Superbike gridded as the second wave.
Sideways.... Green Flag! I got a decent start and was ahead of Ross and leading the race by the exit of turn 3. My weak spot was coming, though. It was the entrance to Turn 5. If I touched the brakes too soon, Ross would shoot right past me. Sure enough, I wimped out and pretty much gave it to Ross. No problem, I thought. With 9 laps in the race, I would have several chances to get around him. Ross had a different plan.
Ross was riding rather strangely. He was all over the track. At first, I thought he was just letting the first lap jitters get to him, but he continued to ride that way, lap after lap. It didn't take long to realize he was riding a blocking line on purpose. Remember, I said this is a really hard track to pass on. I was saying that about people taking the normal fast and predictable lines. Ross wasn't taking the fast lines. He was taking erratic and unpredictable lines, making it not only hard to pass, but nearly impossible. As the laps wound down, I tried one tactic and found it didn't work, then another. Attempt after attempt, corner after corner, whatever I tried was thwarted by his lines. I would back off and try to get a run up on him, I would try out braking him, I would try to get a better drive out of a corner on him. A couple times, he almost ran me off into the dirt, though that wasn't on purpose. It was just his lines made it dagerous to attempt passing in many instances. In all cases, I kept seeing that to make the pass, I would have to either run off into the dirt, or brush fairings with him. I wasn't prepared to do that.
The worst thing was he would often chop the throttle right at the apex in the decreasing radius corners, then immediately run wide to the outside edge of the track. I could understand the blocking lines. I might think it's a cheesy tactic, but hey, if it works, it's hard to blame him for it. But purposely chopping the throttle was just dangerous. I almost rear ended him twice, which likely would have put both of us on the ground.
Ross Wells, #32

I pulled far to the left exiting turn 3, slowed down a little to let Ross gain a gap and finally saw for sure they were pointing the meat ball flag at me, not Ross. Up goes my hand and I coast off the track at the far end of the back straight.
It was bad enough to see what Ross did during the race. Then, to get meat balled on the last lap, when I had one more passing strategy to try that I hadn't tried yet. It was pretty disappointing. After the race ended, my bike was cooled down enough to ride again. I started it and rode it into the pits, all the while thinking the race had been a complete waste of time.
The bike had run warm all weekend, but never showed a sign of overheating. It was hot, and Las Vegas is in dry desert air at high altitude, which can cause things to run hotter. I knew the bike was already a little lean, but I didn't think it was enough to worry about. I think switching to the good race fuel (VP MR-1) is what pushed it over the limit. MR-1 is highly oxygenated, which has the effect of adding more oxygen in the combustion chamber and leaning the mixture out a little. It's kind of like a mild turbo effect. I probably would have completed the race if I had run it on regular pump gas.
Later, I saw my lap times were mostly high '37's and '38's, the best being a 1:37.2 on my last lap before I was meat balled. These times were pretty much determined by Ross' lap times. I never got the chance to try for a '35.

I decided I wasn't going to let that happen again. I realized that my cornering skills and lap times were plenty good enough to beat Ross. I have shown many times that I can run faster lap times than him, even on my 400cc bike. What I now need to do is work on passing. That would have to become my main goal for the next race at Sears. If Ross wants to use cheesy lines to win, I would have to show him it won't work anymore.
My DNF turned out good for others, of course. Richard Moore, #766, got his first second place finish on his FZR400RRsp, and Chris McGrail came in 4th on my 400cc VFR400. Pretty good for starting near the back of the pack and racing a new bike, Chris. Good job guys.Needless to say, I did not race Formula Pacific as it was right after the 450 SB race, and my bike was not up to the task.
