Scott, how does Paul at PPIR define experienced track day participants? I've been to two Chicane and two FAAST. Oh, I should also mention that I was the (only?) one who missed the exit at HPR and the fast group had the pleasant experience to do one lap with me.

Zach, might be interested in the 25th if BadR6 helps me drain my bike before then.

He means that you've actually done a trackday before. You're qualified!

Have fun!

Entirely... Okay, marginally off topic...

Is RS2L ever going to go back to PPIR?

If you can go to this, do it. PPIR is such a fun track to put laps on; if you've never been there, it's worth the trip.

It's a fun little track. There are some issues with the track itself, like bumpy sections around T1 and T2, but it's not as bad as Pueblo.

Rabea, if you need help, give me a call and I'll gladly give you a hand.

I really don't care for the track that much, I will always spend my track $ on the other 2.

Thinking about doing this myself just because I have never ridden PPIR. Going to keep and eye on the weather and see what I looks like for this Monday or next.

Do you have to pre-register? If so is there a cut of date?

Just send an email to paul.jensen@ppir.com to let him know you plan on attending. I don't believe there's a cutoff date, since everyone pays at the track.

I'll see if I can get out there next week. Need to make some bondo repairs and re-spray to the race bodywork on my trackbike. Hopefully I get the time to do so this weekend.

We've been trying, but so far the response has not been in the affirmative. However tracks are facing massive budgetary issues (as is the entire motor sports industry), and with insurance costs rising asking them to let us ride on their insurance policy carries more risk for them despite how safe and clean we run our events. It's just a lot harder to get what we need for a charity event than it was even a few years ago, and I don't know when or if that situation will change.

Because of that I don't know whether we will have an event in 2011 at all, however I do still encourage people to go out and ride at local track days / test and tune type stuff. PPIR is definitely a fun track, and the work we did last season to reconfigure turn 1 for motorcycles makes that part of the track safer.

...and the work we did last season to reconfigure turn 1 for motorcycles makes that part of the track safer.What did you do to turn one? I loved that 155mph drop in with a pretty harsh transition from the bank to the hot pit lane!!!!! The transition was awesome!! I love when the bike shakes, but in a controllable manner.

Another cool spot was coming off the hot pit onto the back straight. My bike would shake all the way up to the wall. I LOVE that track, wish it was longer!

We brought the race line down lower on the banking after you cross the start finish line so that your braking and turn-in is lower and gets the riders away from the wall. By doing that we centralized the impact zone if a rider does go down and can adequately cover it with air fence. The way it was previously left too much of the wall open for impact. I personally like the old config better but we just didnt have the straw bales and the amount of air fence the AMA had when it was run years ago.

And, to make it more exciting, the leaders were coming into that turn as his bike made the last circle and fell over right in the race line. Kim's Mom was out that day, her first time, and I'm pretty sure we heard Mike yell "yee haa" as he slid by at about 130mph. She was in shock for a split second, but when he stopped sliding and jumped up, she understood... Ahhh, the good ol' days!!!!

:pointlaugh:
Im not sure what i said while i was sliding on my back but I do remember yelling to the corner workers to catch my bike during its slow speed ghost circles down the banking. Only damage to the bike beyond the worn down frame sllider and footpeg was a small amount of rash on the bodywork and a bent rotor and clutch lever.. A couple of people said my leathers were smoking when i stood up. There is a picture somewhere of this. The best part of this was i put on a new suit and got on my 750 about 30 minutes later. The looks I got, people who saw the crash couldnt figure out why my bike and leathers didnt have a mark on them.

Loved this turn too, it taught me how to stay relaxed on the handlebars when shit seems to be getting out of hand... loved it!

Turn 1 is not much slower with the new configuration. You're just making your turn in at a lower point on the banking. You can still carry 100mph plus through it.

I've seen 197 at Pueblo (stock gearing). Probably 175 actual.

I think your speedo is off more than that. When Glenn had his radar gun out at Pueblo a few years back, the fastest speed he clocked on the front straight was Hendry at just under 170 on his stroker R1.

With the stock gearing, my speedo was off 10% on a tuned radar gun. Well.. supposedly tuned. A laser showed the same 10%, too.

I've even made runs at the 'radar-speed-limit' signs and they show a 10% error as well. Either way, it's nothing I'm worried about...

The error percentage isn't linear, it grows exponentially as speed increases due to wind resistance and tire slippage.

166 was the highest speed I ever saw at PMI, it was Brad Hendry.

166 was the highest speed I ever saw at PMI, it was Brad Hendry.It's always been explained to me that the error is exponential, but the percentage stays the same. That's how the speedo healers work. You dial in the percentage of error. Again, that's how it is always explained to me.

We did several runs at 100, 120 and 140 and the error was the same, percentage wise. Perhaps the higher speeds do change the error, me haz no clue...

That would be a fun event. Get a bunch of knuckle heads together and shoot everyone with a radar gun. Where to do it would be the problem!

Assuming absolute correlation between bike speed and tire speed, the percentage of error should be the same (obviously 10% of 10mph is a lower value than 10% of 150mph). If the tire speed is altered due to slip or other factors, that error percentage will not be constant and whether it moves your readout up or down is entirely dependent on how it's measured and what caused the error.

At the higher speeds you probably are spinning the tire pretty good. I followed Turpin around PPIR and his R6 left a black mark all the way down the straight.

That and as you pitch into the corner you're rolling of the center of the tire (largest diameter) to the edge (smaller diameter) which would raise wheel speed and indicate as a higher speed on the gauge.

Yeah, I'm just talkin' 'bout the straights, top speed.

Set up a high speed shoot out, Scotty!!! Know anyone with a runway?!?
