Slavvy posted:Basically every bike has an O2 sensor + cat nowadays, the majority of efi bikes have a MAP sensor from what I've seen. They're primitive in that sense, but they also have far more sophisticated systems than cars when it comes to improving rideability and response like secondary butterflies, showerhead injectors, variable length venturi systems and so on Driven almost entirely by emissions. And at that, euro emissions. Though it's not the "lots" of bikes, it's still quite a few bikes that are running grandfathered "emissions" systems. Primitive might be the wrong word. Specialized? Lets go with that. Modern sportbikes have multiple maps you can select from, adjustable horsepower, etc... which are really neat tricks. The secondary butterflys are an electronic version of vacuum slides on carbs. It's there, in a large part, to compensate for problems with having digital fuel controls. Some early EFI street bikes still had the vacuum slides! Others just had awful off-idle throttle control. But if you have a servo driven throttle valve.... now you can do torque limiting and throttle response tuning. Yeah MAP is not great for drivability, but it is good for power. So they're not completely blind. But given the space constraints of a bike, you can't really get proper MAF readings. You'll notice that on cars, the MAF is frequently disconnected from the plenum by a very large volume, and frequently a long hose. MAP also means the bike isn't always going to be able to compensate for changing air conditions. EG: it starts raining, or you go up a big hill. Bikes have always had the high performance aspects of engine sophistication. Big pressurized plenums. Individual throttle bodies. Showerhead injectors were a thing back in.. 94 or 95? Variable length intakes were pioneered (at a production level) on cars. I thought the snap down throttle body extensions were neat when I saw those on the.. R1? Neat stuff, is that common now? Exhaust valves too, were a car thing first? I remember the first bike I rode with an exhaust valve, it was a Triumph 675. The transition from quiet to "Yeah, i'm gonna eat you now" was really fun, and you could feel the change in engine torque.

Nerobro posted:Exhaust valves too, were a car thing first? Well, it really depends on whether you classify the Daimler Reitwagen as a motorcycle or as a car. It's generally a motorcycle configuration, but it also has permanently affixed outriggers for a total of four wheels, and the front wheel has no rake or trail. So while you straddle it like a motorcycle, and it superficially looks like one, it really shares its dynamics more with a car. In any case, it was the first internal combustion vehicle to use an exhaust valve.

Yamaha had servo tuned exhaust runners back in the 80s. exup, etc.

Those vacuum slide Tb's had a really sweet response, I like them a lot. Simple system that gets great results. The snap down velocity stacks are pretty common on sporty bikes now, the Daytona 675 you rode would've had them. Exhaust valves are no longer used for performance purposes afaik, it's entirely a noise thing nowadays. You should post more often.

I'm thankful for the way the motorcycle turns a trek across town for missing Thanksgiving dinner ingredients from a chore into an excursion in gorgeous fall weather. Also for a voluminous topbox and all those bugs that had to die so I could pick up the groceries, sorry fuckers, I hope none of those thuds was a butterfly.

I've accepted the reality that electric motorcycles will never have a very good range, physics being what it is, and the ones that have the best range will always weigh 500+ pounds and cost 25 grand. So I think I'm going to quit holding out for some unicorn and just let electric bikes be good at what they're good at, which is silently and torquily ripping around a city, and now I want a Zero FXE.

I'm not worried about range so much as charging duration. If I could get an hour's worth of riding at speed for 15 minutes of charging, I think I could make that work.

Yeah it’s the charge time for me too. The convenience of filling a tank for 3 minutes and getting 200 miles of range cannot be overstated

My Zero charges at 6kW, and gets an hour of riding from an hour of charge, ish. Most of the big bikes built after mine are capable of DC fast charging (typical equipment goes up to 150kW but the bikes will cap much lower), and should hit your 15 minute goal, though not your price goal quite yet. Unfortunately the Zero FX/FXE go in the other direction, they have smallish batteries, middling range, and tiny chargers, to keep the price and weight down. You’re not going to have your light flickable supermoto that charges fast anytime soon. You can still have a crazy fun commuter though, even if you don’t have a power plug at work it’ll probably have the range needed. It’s still early days for electric motorbikes. They get trickle down tech from the cars and the cars are able to paper over the flaws by throwing weight (huge batteries and cooling systems) at the problem.

If they'd want to keep weight out of the motorcycle, could they keep it on the charging equipment? In the same way that lots of electrical appliances move their transformers out of the appliance itself and into a huge square plug. (I don't know anything about this.)

In the same way that lots of electrical appliances move their transformers out of the appliance itself and into a huge square plug. (I don't know anything about this.) This is exactly what some people do. You can stack external chargers to get up to a pretty high rate. Some leave the setup at home, some build it into a top box or similar. (speaking to gen2 bikes) The move for fastest charging on gen3 bikes (SR/S, SR/F, probably the DSR/X soon) is to get the charge tank then also this double J plug adapter: https://www.emotodesign.com/product-page/dj-rapidcharge, since most level 2 stations top out at 6kw, this will let you use two at a time for the full 12kw. It ain't cheap though. I have the slowest charger on my SR/F, 3kw, which means 4hrs for a full 0-100% charge. It's absurdly expensive to even upgrade to 6kw, let alone 9-12kw, so I just deal with it. It means it's a local toy instead of something I can do any kind of distance on. But the fact that I can realistically only go 50 miles (max if I ride easy, less if I ride the way I do my other bikes) in any direction before turning home is one of the reasons it doesn't get ridden as much as my other bikes and I'm selling it. They make amazing commuters or around town bikes, but just ain't there for longer rides unless you splash out some serious cash for faster charging and even then you're going to be stopping pretty often. Super fun bike but I'll buy back in in 5-10 years when all the stats are improved. opengl fucked around with this message at 16:36 on Nov 26, 2023 |

It was a few seconds of Fortnine riding a Zero on a forested road that made me first start thinking about making the leap from riding my scooter around to getting a motorcycle but I haven’t even considered an electric bike since then. Range concerns and price were my immediate concerns. Even electric scooters, where range isn’t much of an issue, are still too pricey for what they are unless you’re doing a super cheap electric conversion on something you already own. I really like being out all day or for days at a time, so the tech just isn’t there for what I want yet. If I ever get really serious about off-road riding, I wonder if an electric dirt bike I can throw on the back of the Hiace might be a good option but even that is probably years away.

Does anyone make modern electronic gauges that fit in the round gauge buckets of old bikes? I’m going to be getting my 75 Kawi F11 back on the road over the winter and both the tach and speedo are completely shot internally. I can buy used ones on eBay but they’ll probably just die too, plus I’d rather not mess with getting new drive cables and all that. So this has me looking for modern gauges that look vintage enough that they won’t be wildly out of place on a 75 enduro like a trail tech vapor would be

If you stop thinking of it as a motorcycle and instead as an art project… it’s kinda cool! I mean I think it’s hideous but someone thinks it’s beautiful, it’s an art installation that makes noise and can move! I sometimes think that I’m glad someone is making these, because what would they be doing otherwise
