Do they make 2-strokes with catalytic converters? How many miles until you have to replace them, like 100? It is possible to make really awesome stock exhausts that sound great, my 250 Husky is amazing, and my FZ6 really isn't bad, little sewing-machine esque, but not bad when you step on it, plus it let's you sneak out of the campground at 5am to hit the road.

I was trail-riding at a pretty fast pace behind my buddy yesterday- he wanted to know if his exhaust note changed after his Rekluse blew up and he replaced it with the stock clutch. I couldn't even hear the stupid tinny YZ250 exhaust over the bark, bellow, and grunt of my FE250. Does anyone know off-hand how the gently caress the FE-250's 50 state legal? I can't find a cat on it anywhere, is it integrated into the muffler? Did KTM find some sort of bizarre US emissions loophole for small engines?

Elviscat posted:Do they make 2-strokes with catalytic converters? How many miles until you have to replace them, like 100? My Genuine Stella scooter (in my av) is an ‘08, 150cc 2-stroke and it had a catalyzed exhaust. It was also tuned super lean and restricted intake/exhaust wise to squeeze it past emissions. That’s a 1970s-evolved-from-1940s engine design - the Stellas were Vespa PX150 clones. The default move on those was to replace the exhaust and retune the carb basically to 1970s Vespa spec to get it running right - when I did it, it was a change from ~45mph to nearly 60 and what felt like 1/3rd more power. They stopped selling the 2t Stella in 2009. Genuine’s Rattler 110cc was probably the last >50cc 2t for the sale in the US and I’m sure it was catalyzed. 50s are still around. They’d all be catalyzed.

I have zero interest in removing the catalytic converter or changing the exhaust/pipes on any motorbike I buy. If anything, I love the idea of a quieter bike, and ideally would want an electric (but can't afford the initial outlay right now for an electric).

I care more about my bike not being hobbled both in performance and driveability (surging etc) than I do about the impact it has on the environment. On this bike the cat meant the exhaust got extremely hot, on the previous one it made changing the oil even more of a pain. Both reasons to get rid of it. However my next bike I'll probably keep stock as changing such stuff is expensive, there's a lot of misinformation about what does/doesn't work and even though my bike isn't that loud it does still make me a hypocrite as I absolutely hate it when other people make noise.

Did KTM find some sort of bizarre US emissions loophole for small engines? It could be in the pipe. For some reason 690/701 supermotos have it in the pipe while Duke/Vitpilen with the same engine have a huge cat under the engine.

A cat doesn't cause surging, the ultra-lean mixture used to meet emissions regulations and help the cat work properly does. Just removing the cat doesn't solve surging, and any steps that do help stop it work just as well with the cat still in place.

The surging I mostly meant as a reason to perform a tune and, as such, not adhere to the regulations anymore. I've also read that fattening up your mixture might cause the cat to overheat and fail due to fuel burning up in there. However this might fall under the 'misinformation' part.

Yours doesn't have a cat because catalytic converters are not required emissions equipment for motorcycles. https://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&sid=620bf9f924a835822fd4c718d18607cf&rgn=div8&view=text&node=40:19.0.1.1.2.5.1.13&idno=40 I think the more interesting question is how does the 450/500 do it because it also has no cat and has roughly the same emissions standards. I assume the answer is that they run super lean and sip fuel from the factory. 450/500s usually get 50-60mpg stock and when folks remove the reeds in the intake add on a more free-flowing exhaust or drill out a couple of the baffles in the stock exhaust and then put on a new ECU or JD tuner, they get 25-35mpg. I expect there's a similar increase/doubling in emissions but I don't know.

My transition visor came in and it sure is handy, though I'm sure it ups my dad scale. Also, I forgot how nice having a crystal clear brand new visor is, I should buy replacements more often (except the trans one is pricey)

I'm a fan of quiet street bikes and dirt bikes ridden on public lands and say go crazy if its for closed course. When I have a bike that does both, which direction I lean usually depends on the price and how the engine performs with said emissions equipment. The real halo here is electric bikes. They can't come fast enough.

It finally happened. A young American guy asked me which brake to use on his Honda Today 50cc, equipped with what looks like a 3" front drum, and when I said both he replied "My dad rides bikes and he told me the front one is super dangerous" and I had to patiently explain reality for a good ten minutes.

Just the notion that by having a tune done you're not complying with emissions regs anymore so you might as well go the whole hog and do the cat too. That might not be the way you meant it but one of those things is much worse than the other. To the OP re: keeping cats, I'm with you, man. I am constantly giving people poo poo on FB in car groups I'm in when they decat or ask about doing it. It's loving antisocial and for what? Ooh, I get flames out of my exhaust now!

As someone who lost like 50% of their hearing to repeatedly ruptured eardrums, wear the ear protection. You know what’s even more uncomfortable than earplugs? Being deaf Losing your hearing isn’t some magical volume knob that means you are less susceptible to loud noises damaging your hearing. If anything you’re MORE susceptible because you can’t hear it and how loud it is as well as someone else can

My Rex with the aftermarket (catless, but it was catless stock too, sorry chief) exhaust is quieter - for me - than the Weestrom was It may be different for people behind me. But it's also obviously not an open pipe or anything dumb like that. My brother's first bike was a z750 with a farmer-rear end slipon with the baffles removed and it was loving obnoxious for both me and him.

right arm posted:what? HUH? My FE250 very obviously uses every single dB of the legal limit and it's just about perfect. Some of the new helmets like the GT-AIR really do get even highway wind noise down to below the hearing-damage threshold. I'm terrible at properly following hearing conservation guidelines, but I also get mandatory audiograms every year, and I haven't really deveated from the baseline I set about a decade ago so...

goddamnedtwisto posted:If your exhaust is even vaguely close to legal then it is no risk to your hearing whatsoever. Weeeellllllll in the USA the federal motorcycle exhaust noise limit is (roughly, as it varies depending on the bike's model year and displacement) 82dB at 50 feet. Four feet from the exhaust pipe it's going to be significantly louder than that, and 85dB is the point where OSHA requires employers to make hearing protection available to employees as it will cause hearing damage with chronic exposure. It is possible for your exhaust to be street-legal but still pose some danger to the rider's hearing. Of course, the wind noise over your helmet at freeway speeds can hit over 100dB so that's a much more significant danger than all but the most obnoxious rear end in a top hat exhaust systems. Mirconium posted:I dunno, my personal argument is that I don't like earplugs and I already lost about 20% of my hearing to being on a rifle team in high school, but to each their own. hearing loss is progressive, so every time you go out and ride fast without ear plugs you're adding another .02% to that figure fyi I always wear earplugs unless I'm literally going around the block, and in that case I make an effort not to go past like 50% throttle. Maybe I am a little more picky about hearing protection but idk, I also work in a machine shop and fly small planes so my overall noise exposure is a lot higher than most of the somethingawful white-collar computer toucher crew Sagebrush fucked around with this message at 21:08 on Oct 20, 2019 |

Somebody get on this please Microturbine aside (because I think it'd be a maintenance nightmare) I'm kind of wondering when we'll see an honest hybrid bike effort, where you'd pair a 500cc motor with a huge electric motor and lithium ion battery pack with a 1kWH capacity. Use the torque from the motor to get you moving/up long hills and the 500cc motor to keep you running. I'd buy it because the worst goddamned thing in the world is getting stuck on a blazing hot summer day in traffic in a non-lane-splitting state notorious for its poo poo humidity levels. God, I'm glad I left Georgia. Riding up North here has been a loving dream and I'm literally looking forward to getting on the bike again instead of dreading the sun.
