Chillin' Pete vs. All-out Lou

[loudog]

I strapped a QStarz timer on Pete's bike last TTD (thanks Pete!) and compared one of his laps to one of mine. Obviously, Pete can only go so fast because of traffic. Here is a video of the playback in the QRacing software. I'm the orange dude and Pete is the green. This is what four seconds a lap looks like:

YouTube- 4 seconds at Loudon (NHMS)

It's really cool to watch braking points, top speeds, and obviously the time between each split. From the start/finish to split 1 (right after turn 2) Pete already has 2.4 seconds on me. He picks up another 1.8 between the exit of 2 and the bowl, and 1.5 seconds through the bowl. I gain some ground on the backside of the track, due to Pete running into traffic.

The graph on the bottom is speed vs. time, and the yellow dots are the splits.

I have to spend some time with this info to see what I need to be doing to get to 1:24s. Maybe someday...

[slammp]

That was pretty slick to watch.

[Awesome]

I can definitly tell you just from watching that, a lot that you're doing wrong. All of the typical beginner trouble spots.

[OreoGaborio]

This is pretty cool....

Lou, do you know if this was this your best CLEAR lap or was there some traffic in your lap as well?

Fill me in!!

This was a clear lap for me. That's the best lap I've run with timing. I know, I know...I'm a slow-poke. I'm working on it

yes, let's hear it!

[Awesome]

Coasting past the apex in 1, and using maintnance throttle instead of putting some power into the bike from there until the enterance to 2. Get on the gas earlier to make a drive through 2.

On the gas before the bumps in 3 to absorb them through the corner, instead of being scared and waiting until after you feel the bike going over them to complete the turn and continue on. You're actually rolling off at and through the pavement transitions.

Get on the gas and continue to accelerate all the way through the bowl, don't roll off to correct your line, continue through it on one arc. Stay on the gas all the way through 7 and 8 following the line. Stay off the seat and ride the bike, don't cost it, then brake in a straight line on the entrance to 9.

Get on the gas in 9, don't scrub speed off. Get off the gas just to turn the bike into 10 and get back on. Don't wait for the bumps in 10, same as the bumps in 3.

Nice, thanks for taking the time to write that. Good info and stuff to work on.

Getting hard on the gas through 7 and 8 seems to be a big weakness of mine. Definitely could use some more juice through the bowl too.

As far as the bumps in 3 and 10, I'm sure I'm on the gas through those spots. If I'm not, the bike let's me know pretty quickly. Maybe not on the gas as hard as you'd like to see though.

I definitely have a bunch to work on. Luckily I'm headed to the track in a couple weeks

[Chippertheripper]

I would also suggest coming to a race day to watch how the ex's come through certain spots. In addition to what that dude wrote, studying what guys like narbonne do in different spots can be a real eye opener. Bring a notebook.

[Kurlon]

Bring a notebook.

And a moist towelette.

[Marc R]

... and the yellow dots are the splits...

Just curious, are the splits reference points or anything specific?

I started using the same Qstarz logger earlier this year, I like it alot. Next TTD track walk I'm taking waypoints of my reference points.

Rolling on the gas as the bike leans over are two counteracting forces compensating. Even if the engine revs rise, the bike can maintain speed or slow down. You need to be on the gas enough to push the rear wheel with some drive, the torque will raise the ride height of the suspension and absorb the bumps. Keeping up with the change of radius at the contact patch of the tire by giving it just a little gas helps more than compressing the suspension by being off the gas, but it doesn't extend it like you need to do.

The front suspension acts the same, because weight is being transfered to the rear of the bike.

So, on the gas putting down torque on the swingarm is why you need to get past maintnance throttle and slight increases in revs.

Yeah, that's something I haven't done for a LONG time. I just started to get a bit more serious about my riding...hoping to race in a bit. I'll have to make sure I get up there before the end of the season with a notepad.

I just threw the splits in semi-randomly. I had the same plan as you, next track walk, take the Qstarz unit along and log some key points.

IIRC, we worked on some of those things during one-on-one, right Lou?

[KillBill]

Really cool stuff!

[mi1knc0okies]

that thing is awesome! i want one!

Thanks again. I'll try to get on the gas a bit more and see how it feels.

Yeah, big time. You guys should have seen my riding before Ken got a hold of me

Smooth...but slow. I picked up at least a few seconds in one day working with him and Joel. After a couple more track days I think I'm going to be ready for round two Ken!

Does that thing give real-time feedback on the bike or do you have to offload it to a computer with the software?

I am currently shopping for a lap timer that shows lap times on the bike and also has data-logging capabilities yours has.

You have to download to a computer, no real-time feedback. Less distracting that way.

Have you found any good units with a real-time display? Definitely a cool feature, but some track days don't allow real-time lap timing.

I can also tell from those little moving dots that you need to lower your head a bit in the corners and you should try decaf coffee.

[OreoGaborio]

Lou, you're all crossed up in that video!

[wiggeywackyo]

I've looked at the XT GPX Pro and the Starlane stuff. I like them for some of the extra nerd toys they feature.

You guys are GOOD!

Yeah, I'm a big time nerd when it comes to data like this. It blows my hair back.

[davemon]

Aw man that is awesome, I so should have rented one of these at the last event.

[a13x]

Oh my. I like that GPS unit. I might have to get one of those.... image it'd work on Supermoto and MX too yea?

Pete how have you liked it? Any reports/reviews up anywhere (knowing you I'd imagine you've typed something up).
