First track experience for the MX5 - BSCC 1



Man is was a COLD and rainy day for the first round of the Bremerton Sports Car Club Kitsap Kup autocross series held a Bremerton Motorpsorts Park, Bremerton WA. Pictures of the event are here: BSCC - Round 1 Gallery

This was the competitive debut of our little race car. With 172,000 miles on the engine, trans and clutch and sporting only the finest in low-dollar used-car-lot tires it was an event to remember!

Since this was the first season of racing it qualified or Novice class which acutally is farily competitive since the Miata would have to face cars such as the Mini Cooper S, Subaru WRX and Chevy Corvette's. It's a run-what-ya-brung class for beginers and I certainly fall into that category.

With the horrid tires, stock work out suspension and a general lack of skills I did not place especially high in the rankings but I sure did have a GREAT time! Here are my results for the first event:

Novice Class:

19 Harry Evans 500 2002 Subaru Wrx 72.569 (0,0) 82.477 pts.
20 David De Martin 3 1900 Mazda Miata 73.489 (0,0) 81.445 pts.
21 Joe Berentsen 200 1980 Mazda RX-7 74.302 (0,0) 80.554 pts.



Overall Times:

84 Harry Evans NOV 72.569
85 Ryan Skyler LS 72.687
86 David De Martin NOV 73.489
87 Joe Berentsen NOV 74.302
88 Richard Johnson MS 74.478

Review: 2004 Kawasaki ZX-10R

I realize that up to this point all of my blog entries have been about photography. And way not it truly is a passion of mine. But so are motorcycles and since this blog is about bikes as well it’s an opportune time to post some comments about one that I took for a test ride recently.

First off, I’d like to thank Dave at Westsound Powersports for loaning me the bike to check out (Here is the current ad).. When I received his call the weekend prior I could hear the excitement in his voice. “Dave, you have GOT to try out this bike. It’s mind bending. Can you meet me for lunch Wednesday, we’ll take her out for a ride.”
Hm, now how could pass up the chance to experience one of the fastest most brutal motorcycles in production today? I couldn’t.

Here is a little rundown of the beasts specs

Wednesday came and so did the first rain we’ve seen in what seems like months. Figures. So the ride did not go down Wednesday but I did drop by the shop to chat and check out the new inventory (both they have some nice stuff in right now).
We decided that if the weather held the next day we’d go, and as it turns out the sun did return yesterday and we met up for lunch and a ride.

First Impressions

First off, the thing is feels very light. A lot like my wife’s ZX-6R. Svelt for a machine of such performance for certain. My Ducati almost felt wider and defiantly a lot heavier than this thing. Seating position is very agreeable (then I find the Ducati agreeable too, take that for what it’s worth to you) with the clip-ons low and wide and very long grips.
Instrument panel is jus like the ZX-6R. Nearly worthless. Then who’s looking at that stuff anyway, it’s the road and your corner speed you need to be judging and let you other sense tell you what the bike/motor are doing.
The tachometer is an LCD sweep that is difficult to read during the daytime and likely only marginally better at night with the back lighting (that’s the case with the similar ’03 ZX-6R). Speedo numbers are easy to read from the large digital display. Neutral light is easy to see as is the highbeams light.

Getting Started

Firing up the stock bike nets a slight vibration from the motor but overall a very quiet bike. Mirrors are pretty effective for a sport bike. They are far enough out that you can see past your elbows and actually detect vehicle behind you.
Controls are in conventional locations but one thing that was a bit weird was how difficult it was to cancel the turn indicator. Ah well, perfection is in the hand of the beholder I suppose.

The Ride

The roads here are narrow and tight so a full-speed blast would have to wait for a track day but she hits 120 with ease and not much notice. This is where the big digital speedo readout is pretty cool. It’s easy to tell you are at jail-time speeds when you see triple digits on the readout. Living in a rural area with long sight lines has it’s advantages.

Holy demon from Hades, Batman!
With that out of the way I’ll delve into the details.

Transmission

Shifting was precise with neutral easy to find and hardly any lurch when dropping the bike into 1st gear from neutral with the clutch all the way in. I did not have any missed shifts or false neutrals. Clutchless up-shifting was also smooth. The biggest thing I noticed was the lack of rear wheel hop during hard downshifting into a corner. In fact I was trying to get it to wiggle and it just wouldn’t! Then I dawned on me that this thing has a factory slipper clutch and it works! Clutch takeup was also smooth and lockup was not grabby as some Hondas get when slipping on a steep uphill launch.

Throttle

Very easy to manage. At no point did I feel that the injection system gave the throttle response a jerky on/off/on feeling as quite a few FI bikes do. It seemed well mapped without any glaring torque pits in the curve up to 9,000 RPM (which is all the road that was available to safely stop in). Even though this bike is NOT for newbies the throttle is very manageable.

Brakes

Fairly impressive but not earth shattering by any means. Intial bit was pretty soft and it just does not haul the bike down from ludicrous speed with the amount of force I expected from the new fangled radial brakes. Sure.. I might be jaded having tested the Brembo’s on my bike at 160+ but for a bike with this amount of power to have brakes that would bite right off the bat. Stainless brake lines and more aggressive pads would likely improve the feel enourmously. I guess I was just not impressed with the brakes but there is also nothing wrong with them. The pedal rotors and radial calipers sure look the business though.

Engine / Acceleration

Again… Holy demon from Hades, Batman!. This thing freaking RIPS! Low to midrange torque is defiantly there and lots of it. More than I expected. On the first lauch I found the bike did not require as much clutch management as I had expected. Again the FI was smooth and at low speeds the engine is very tractable. You do have to be cafeful not to whap the throttle open after about 6,000 RPM unless you are looking for aircraft because it will loft the front end.

Again though, this is no bike for a newbie. It will not suffer fools kindly! If you are new to the sport this IS NOT the bike to get. Pain, suffering and death could be the punishment for writing a check you brain/body can’t cash.

Cornering

In a word. Twitchy. The steering angle seems pretty steep and with even the slightest of input crudeness the front end can get a little upset. This thing NEEDS a steering damper from the factory I have no doubt about that. The only other bike I’ve ridden that felt this twitchy on the front end was the wife’s ZX6R and that is not quite so bad and it’s not nearly as deadly a machine.
Corner stability is good IF you don’t get ham-fisted on the throttle. Get a little chop-happy mid corner and this thing will reward you with a nice wiggle from the bars reminding you quite clearly that you need to be smooth or it’s likely to toss you off. High-sides are the least fun of all crashes.
With a damper fitted and the suspension dialed to one’s weight I think the machine would be a solid corner weapon as well as a top-speed demon. I did feel a tiny bit of mid-corner ‘wiggle’ but my bike did that too before I set the rear ride height properly, so I would not hold that against the bike.

Overall Impression

I like it!! I really think it’s a fun machine. It belongs on a track and given the opportunity that’s where I’d take it. She’s fine on the street too but the smaller ZX6R is PLENTY of punch for the street. 180+ MPH has no place on open public roads. On a track though.. I think it would be a real eye popper. For the right, responsible person this bike would still make a great street bike no doubt but, I think it’s real calling is the track.

If I had the budget for a $10,000 track bike today I’d be posting a photo of my latest bike.

Canon 20D initial impressions - real world field test

It's been unseasonably warm and dry here in the Pacific Northwet (no, I did not mispell that) and yesterday was no exception.

Despite some mechanical difficulties with the photo project car I did make the 180 mile trek to Portland International Raceway to try out the new camera. The journey was well worth it from both a photographic and a motorsports standpoint.

Camera Performance
In a single word, flawless. Well, nearly flawless. During the first 100 frames or so shot I had three seperate instances of an 'Error 99' condition that would hand up the camer requiring me to turn it off then back on again and in one case remove the battery to clear the condition.

I'm not sure how many frames I lost during those incidents but they were far from enjoyable. It seemed to have something to do with the shutter. Perhaps it was due to the camera being new because after the three instances I continued to shoot for the remainder off the day (about 800 frames) without a hitch. In fact at no point, despite leaning on the shutter release pretty hard, did I run out of frame buffer and have to wait for it to write to my relativly slow (20x) cards.

There are three auto-focus modes on this camera and unfortunatly I was about 1/2 way though the day before I reliezed I was using the incorrect setting, 'One Shot'. This is why I try to do some shakedown events before the big paying gigs start with the regular racing season.

That is not to say these track day events are not important. In fact I enjoy them as much if not more than the bit international events. Access to participants is unlimited, there are no crowds to fight. It's a very relaxing way to shoot pics and try out some new techniques and not have to worry about a client/editor questioning the more experimental of compositions.

Digressing, the camera is a joy to work with. The added weight over the 300D was not an issue at and the added rubber grip areas on the body are well located making it very easy to handle.

The massive (compared to what I am used too) frame buffer and quick 5 fps made action shots far easier to compose but I did burn though 2.5 GB of memory in less than 3 hours. Much faster than I had expected! No problem, memory is pretty cheap these days.

Having only had less than 24 hours to really familiarize myself with the body before the shoot and having to arise at 4:45am to make the track on time, reading the manual was a luxury I was not able to enjoy before my trial-by-fire test. Thus, as mentioned before I was working with the AF setting most of the day.

The cars were moving along the track at a fast pace so once I switched over to AI Servo and AI Focus did things quite literaly maintain a much better focus.

My inital impressions of the camera's performance and ease of menu navigation gives the camer a 9 of 10. I don't know that there will ever be a perfect camera for me but this one is pretty nice and quite affordable compared to the 1D line of bodies.

Experimentation
As mentioned I spent a good portion of the afternoon experimenting around with some techniques other track photographers I've met suggested and I'll give a short review of them here.

Slow shutter speed
After having a number of my photos reviewed one of the tips given me was to show down my shutter speed. Typically I shoot at the faster speed that ISO 100 and light allows. This does a great job of keeping things sharp but it tends to freeze the spokes of wheels and give the meachine an almost 'parked' feel to them robbing the images of action.

Taking this into consideration I slowed my speed to approximatly 1/4 of my normal speeds for most of the day. Granted some of the sharpness issues were panning errors on my part and the spokes of wheels certainly did become more blurred I found the sharpenss of the images especially in cases of near on-axis approach/departuer left too much blur in the rest of the subject as well. Next time out I'll not cut the speed down so much and see how that affects the way wheels look. I'll post some example pics later on this week as I do have over 1000 images to review and process.

Angles, mixing things up a bit
Another suggestion was that the images although framed well lacked a certain amount of artistic expression. Not one to deny expressing myself I cut loose with new angles and camera possitions and realy learned some interesting things.

One lesson that supprised me was that shooting from track level is not always the most interesting. In fact I found some of track-level images quite horrid (and I promise will never see the light of a CRT if I can help it) and some of the images I like best (especially from Turn 9) were taken atop the grand stands.

A few notable exceptions were the images of a Porsche 911 losing control and heading straight towards me before the driver regained control at the last moment spreaying dust and rock into the air. Outside of that, most of the track level images taken in turns 1, Festival and 9 where quite unremarkable until I started to introduce some more tilt to the camera off the 'normal' horizontal orientation.

Playing around with the off angle provided some very pleasing results.

It's Here!! The Canon 20D has arrived!

Much to be said soon.. I've just unpacked it and checking it out. Wow.. I live the way it feels in ones hand. Heavier than the 300D but I'm sure I'll get used to it (I've lost 30 lb. in the last 2 months so an extra few oz. of camera is not likely to slow me down much).

Tomorrow (Saturday, March 5th, 2005) I will at Portland International Raceway for the first test of the camera, to be followed by CART team testing at PIR 5 weeks later. I'm sure I'll have some more significant comments on the camera body once I've put it though it's paces in a real-world test.

More to come...
