So another thing I've treated myself to alongside the new bike recently is a camera: A Nikon Z6. I haven't been into photography since high school (always considered myself more a sound guy) but I'm loving shooting with this thing. I've gotten a few pics of bikes so far. Not enough, but a few. Most of those linked above are from one Thursday night meetup here in Toronto. Here are some highlights:        Now this one freaked me out. As some of you might remember, my old bike - a 1988 GSX-R400 - was stolen from me about 12 years ago. When I pulled into the meet, this was the first thing I saw, and I immediately felt an adrenaline dump, like that's my loving bike. I rolled up, wondering what I was gonna say, and then noticed the different frame and the '750' on the tail, and breathed a sigh of relief. Mine was in similar - pristine - condition. In retrospect, this was really nice to see. I also took some shots of my new Gixxer at a local water treatment plant.    She needs a wash, I know. Most of these shots (at least, the nighttime ones of the meetup) were shot with a 50mm f/1.8 lens, which I find myself using a lot as it's great for low-light and the bokeh is crazy good for portrait-distance shooting. I feel like the DoF might be a bit too razor-thin though, as you can see in some of these shots the tails of the bikes are out of focus. The other lens, which I think I used for the Gixxer shots at the waterworks, is a 24-70mm f/2.8. If there are any other shutterbugs ITT, I'd love to hear some tips about shooting bikes.

I’m basically treating it like another car. I load up my crap, take it places and soak up miles on the highway. I have a meeting this afternoon. Toss my laptop in the side box, hop on the bike in my work clothes and head out. It was soooooo built for that purpose and feels great doing it. Also today I learned it has self-cancelling turn signals which in 1986 must have been black magic voodoo level stuff

FOR THE LOVE OF GOD DO NOT TOUCH THE GOLDWING'S CARBS. Randakk makes it look super easy, https://www.youtube.com/watch?v=XB69_2j9Y4k But the reality is, at least 50% of the time you crack into a set of those carbs, you'll never be able to get them operational again. Less so if everything isn't in perfect shape.

This is a thing I've been preaching forever. You definitely traded up on that rad beast, though. Keep posting pics and reports. Dare I ask why goldwing carbs specifically can't be removed for service, assuming you kept them organized and did the cleaning properly? What could go wrong?

Except that in the case of the GL carbs it's not even like they're a pain in the rear end to reassemble. It's more a matter of, "is there going to be a giant vacuum leak or not?" Getting that plenum to seal is a giant pain in the rear end, even with 1500 grit, the straightest of edges and feelers and a lot of patience. Don't even get me started on finding seals that actually fit and o rings that don't melt immediately. Randakk's is really the only way to go but goddamn is it expensive, for a bunch of little rubber bits. https://www.randakks.com/randakks-own-gl1000-master-carb-overhaul-kit.html

MomJeans420 posted:What exactly does unracking carbs mean/entail? I tried googling it but didn't really see anything helpful other than people saying don't do it. Multi-cylinder motorcycle carbs are just two or more identical carb bodies "bolted" together. They use linkages between them to sync the butterflies so that they open and close precisely at the same time. "Unracking" means unbolting them, which can involve some complicated linkages on carbs like on a i4 or v4. After reassembly, they have to be re-synced. *edit* here are two sets of carbs from a VFR750F on my bench, flipped over. You can see the linkages going between them:  Unracking means complete disassembly of the whole carb rack. Gorson fucked around with this message at 20:01 on Aug 28, 2019 |

They also involve like 40 rubber o-rings that seal each connection between the carbs. Guaranteed one will crap out and when you put the carbs back together and sync them they will leak fuel or air

I've always found it helpful to park the bike so the shadow is under/behind the bike instead of in the foreground.  Sometimes (a lot of the time) the ideal lighting and ideal setting/angle don't intersect. Imgur seems to have eaten all my good bike photos but with sportbikes the front quarter angle is probably the least photogenic cause it makes the fairing look bulbous and weird. Phone pic but you get what I'm saying:

If your camera has an HDR mode, grab a tripod and give it a shot. It’s hard to get engine stuff to not be underexposed when you’re exposing for shiny and complex bodywork. A couple exposures with high smoothing will make it not obvious that it’s HDRed.

Slavvy posted:I've always found it helpful to park the bike so the shadow is under/behind the bike instead of in the foreground. I agree w/r/t the angle, but there's a lot of things going on in that photo that make it better than the stuff Mister Speaker's shooting. - Figure to ground: the blank wall behind the bike that lets it stand out from its surroundings and gives you a sense of its overall shape. (Otherwise both the bike and its background are a jumble of complex shapes that don't give the eye somewhere to land). This is probably the most important thing and what make's speaker's photos kind of meh at the moment. - No lens distortion - the photographer's back far enough that the bike's not being warped by the width of the lens. - Height relative to the subject - the photographer's crouched down low enough that we're viewing the bike at its level rather than below or above it, where it either looks small and pathetic or fat and ungainly. - Enough space around the bike that it doesn't crowd the entire frame. Mister Speaker, if you want your photos to be more better, compose them so there's nothing intersecting their outline in the background (other bikes, cars, buildings, whatever), take a couple of steps back, and crouch lower.

I would do that, but I'm too addicted to the long exposure motion blur. :P Thanks for the advice guys, cool stuff. I also noticed (and a photog friend pointed this out) that I should be shooting a little on the underexposed side; some of the background white is blown out and most of that can be adjusted for in post if I'm deliberately underexposing. Also some shot composition stuff, and use of saturation and vibrance to bring out the colour.

I don’t mean to belabor my point, but this is exactly what onboard HDR is meant for and can keep you from having to mess with in post. I shoot on a D5100 and it’s excellent at doing that for landscapes in the evening without making it obvious. The downside is that it’s difficult to tell how well it’s working on the little screen on the camera. If your camera doesn’t have the function, it’s moot though.

Mister Speaker posted:Some long exposure tests. I think I need to pick my lighting and background composition better. Keep playing with composition in general - back away from the subject (you'll probably get more use out of that zoom lens than the 50mm prime), play with its placement in the frame, and as mentioned watch your exposure everywhere, not just the bike. We've all seen black GSX-Rs, you need to create a sense of motion or place it in a scene with visual interest. The only reason anyone will look at 6 photos of the same bike at medium distance in center frame is when they're attached to a post on Craigslist.

I looked it up and the Z6 will to in-camera HDR but oddly only if you're shooting in JPG. I think there's an option to save all the exposures as NEF/RAW so you can do it manually though. Honestly, I still don't really 'get' HDR. Composition is something I've always sort of prided myself on, insofar as before I got this camera I'd use my phone and make sure the frame is full and the subject is 100% visible. Using a real camera for the first time since 11th grade, I'm quickly realizing there's more to it than that. I want to get the bike as big as possible in the frame but that doesn't tell much of a story, does it?

Yeah, a carb "rebuild" is just taking off the float bowls and replacing those gaskets, o rings, and float needle. The jets are also there. I would guess a 240z would have a similar set up with linkages requiring a sync. On old cars most people simplify this with a more modern single carb conversion kit.

I can definitely understand some carbs having much more finicky mechanisms than others. That said, I unracked the carbs on my XJ600 so that I could replace every rubber bit and hopefully never touch them again (it worked). Also, it was the only way to dip them in the gallon can of Berryman's I bought for the job. Re-racking them was fine. I bench synched them with ball bearings, and then finished them up with a pair of manometers (synching 1 and 2, then 3 and 4, then 2 and 3). Aside from breaking 2 out of 4 emulsion tubes, it was a pretty simple process, just tedious. They ran wonderfully for years until I sold the bike a few months ago.

Slide Hammer posted:New technique detected. What is this? For an I4. Rerack the carbs, and set them intake side down on a flat surface. Drop a ball bearing into the carb opening so it rolls to the lowest point on the butterfly. As slowly as you can, open the throttle. The goal is for all the ball bearings to drop through and hit the table simultaneously. So when the first bearing drops, you back that set screw off a little and repeat until carbs 1 and 2 drop simultaneously and then 3 and 4 drop simultaneously (because the set screws are paired 1&2, 3&4, 2&3). Then when you have 1&2 and 3&4 paired, pairing 2&3 should by extension pair 1&4 and all 4 will be opening the butterflies precisely together. If you have really steady hands, you can even catch the BBs before they hit the table and really get precise. This gets you in the ballpark. Because of differences in valves, it's really improbable that carbs will both be synched to engine aspiration and themselves. So once you synch them all to each other, it's much easier to synch them to the cylinders rather than chasing vacuum pressures around without knowing where they started relative to each other.
