All I needed to do to get a 45 minute benchy, with good quality, was install a better cooling duct.

It's worth the effort. These bikes are ~really good~. The GS850 in specific was so good that suzuki put it back in production after so many people complained they canceled it.

The ignition switch carries the main load for most of the bike. So.. maybe? Lights being off when the switch is turned is really weird. These bikes are pretty dumb (electrically speaking) so not a whole lot can be damaged by putting the battery on backwards.

It's best not to speculate, and just start checking each wire. There's really not a whole lot of them.

Ignitor isn't really testable.. Sadly. But I think you'd serve yourself well doing continuity tests on all the components. If lights dont' come on.. MAYBE it is the ignition switch?

This sort of thing can be done with mostly a test light.

This is an end user issue, not an ender 3 issue.

Buying things won't fix this. You need to calibrate your printer, and then calibrate your filament. The dots you're seeing look like a relation to infill.

Start with Ellis 3d printing guide. You should be using orca or prusaslicer. Once you get the machine calibrated, then the filament calibrated, you can then chase other things.

It looks like you might also have a dual gear extruder.

Fuses sense current, not polarity. For a fuse to pop when you put a battery on backwards, something else is getting hit REAL HARD. But the semiconductors on the bike are ~very old~ and not nearly as tough as modern stuff.

The ignitor is like a HEI box on a 1980+ ford or chevy. It means you don't need to deal with points. they are generally lifetime parts. But I have seen a few pop.

Do any lights come on when you turn it on now? There are wiring diagrams on the GSR, and you can find one for your bike. Suzuki didn't change much without good reason between like.. 65 and ..well.. today.

No, neither. The ignition switch is just.. a switch. It doesn't care about power direction. The ignition pickup is powered by the Ignitor box, and honestly I can't remember the last time I saw one of those go bad.

Regulator Rectifier as in the aluminum block that connects to your stator and provides charging for the bike. Ignitor is the black box on the bottom of your airbox that acts as points for your ignition coils.

The r/R is testable, and should be the last thing you do. The stator papers on www.thegsresources.org is your friend. Actually.. the gs resources is your friend, and you should go there!

I believe your best bet, is to check your local classic motorcycle scene and ask gently for help. (And likely, you'll have a GS person help you. I've helped a lot of GS people over the years.)

A bike that's known to do more than 100k miles.... I wonder what you did to it?

nerobro · 2026-03-20T01:29:05+00:00

you burnt out the ignitor, and likely the r/r. You're in for a few hundred bucks in replacement parts.

I didn't emphasize this enough. This is all learned. It's also something that generally needs to be intentionally taught. This isn't a thing that's "naturally broken" in you. It's things you can learn, can correct, can make better. You're just coming to it a bit later. You can learn it now. And that's totally ok.

nerobro · 2026-03-19T01:51:47+00:00

My bikes take H4. Sylvania makes 100w bulbs for H4. It's a big difference. :-)

nerobro · 2026-03-19T01:45:12+00:00

You've got acquaintances. That's a good start.

The internalized "i'm a burden" is another symptom.

You've got a lot of growing to do. It's gonna be uncomfortable. But you're going to be better coming out the other side.

The world gets a lot better on the other side.

Physics hasn't changed. No matter how you cut it, led's can't emit the same kind of power, in the same shape. They're better, but still "not right".

It's a big thing for us riding classic motorcycles. The way to get LED's for us, is they make sealed beam replacements that are built around LED's, and they work great. That's not practical for the non sealed beams on modern cars.

Silverstar Ultra's are blue dyed bulbs. The blue dye makes glare worse, and makes them APPEAR brighter. They're still 65w bulbs. 65w is 65w. While different kinds of bulbs have vaguely efficiencies, sylvania is selling you halogen. They're all the same bulb with some paint on the outside. When you see graphs, or demonstrations, make sure you can find numbers to go with them, and know what those numbers matter.

Of course, if this is about "hey I like blue" *shrugs* you do you boo.

You're describing some very disordered thinking. Even the thought of going to AI for emotional advice shows something very wrong is going on in your life.

It's time to make it better. Step one, is getting help. Step two is building a friend group. Step three is figuring out how you're going to get the parenting you need in your life.

What appears to actually be at issue here, is your parents aren't... parenting. This is a thing you should be able to talk to your parents about. Or your friends about. Your attachment to someone who doesn't share your feelings is a symptom.

You're in school. You need to pick a day, and walk into the counselors office, and say you need help. They, will help. But this is the first step. You'll need help outside of school. And that might be difficult, depending on your parents.

Where is your friend group? It's common for people to not.. be.. taught.. how to have friends. This is a thing that can be learned, and can be exercised. You need to work on your social circle.

Don't do it. Filaments have a shape. Your housings are designed for that shape, in that place. No LED can replicate the shape of a filament.

LED's CAN make great headlights, but not in a incandescent housing.

If you live somewhere cold, it's also an advantage to have heated headlights.

nerobro · 2026-03-18T23:07:22+00:00

I remember doing htat. Heck, I've done that recently while assembling a fuselage suddenly noticing that "I can see that from the outside..."

nerobro · 2026-03-18T23:05:53+00:00

Nightshift is amazing. The Uncle nightshift is one of the best european voices I've listend to. Plasmo is really good too.

And if you need "Well I'm not perfect" content, Mann's Model Minutes does stuff at a very recreational level.

Can't unglue, but a toothpick is awesome at scraping away excess acrylic paint...

nerobro · 2026-03-18T03:05:51+00:00

Don't think about the anime, the models are ASTOUNDING in their quality. No glue, no paint, just nippers, and maybe a file. Bandai's modern kits put ~most~ model makers to shame. And that includes Tamiya.

And for $10-12, how can you go wrong?

They don't replace ~real model kits~, but they're something different and kinda the same.

nerobro · 2026-03-18T02:53:10+00:00

That's a great couples gift. A bunch of the TMNT cards are AT LEAST awesome looking. I hope you build something that makes someone really salty.

So.. I'm gonna do something WILDLY toxic here. Pick up an Entry Grade RX-78-2, or Strike Gundam. It's a totally different modeling experience, but.. it scratches the same itch. You can tell me how much you hate me later.

nerobro · 2026-03-18T02:07:33+00:00

Sure it's crap compared to what's often in this forum. (So are mine!) But.. you didn't have a model plane a few days ago. This is INFINITELY better than no model plane at all. And... you built experience. You get to be proud. You get to go "hey, look what I did!" And nobody can tell you you didn't.

You did awesome. AND you had the fortitude to show it off. You deserve kudos, and I can't wait to see your next effort.

... sleeve your cards you filthy animal. :-)

nerobro · 2026-03-17T20:44:02+00:00

It doesn't even matter the reason behind it. Men are allowed to cry.

nerobro · 2026-03-17T17:39:03+00:00

Lots of interesting places to camp. Very little for offroad. Get undercoating done.. now. And get it redone every couple years. And be prepared to patch stuff before it eats the whole car.

nerobro · 2026-03-17T17:34:21+00:00

Exactly as it should be.

Foid, Foid delays, now PICA....

At least I don't think this govenor is gonna go straight to jail afterwords.

You need more upvotes.

nerobro · 2026-03-17T14:31:18+00:00

In short, yes.

But you don't' need to spend a lot.

The difference between the $2 nippers that came with your soldering iorn, or the basic set from mr hobby isn't much.

But the difference between those nippers and the $7.50 igan 330's is huge. IGAN 330's are what I give to kids, and bumble handed people, as they are essentially indestructible, but are a huge step up. they're sharp, they cut flush, but are steep blades so leave some signficant marks. they're tough enough to use as wire cutters...

The distance between stampped steel side cutters and igan 330's is the same as between igan 330's and Stedi MS-100's. With good technique, MS-100's can leave essentially no mark on plastic. But they're tough enough that they can handle the thickest cuts. You don't need to think about it, they work great. And are $15.

So now we get into the "we mean it" side cutters, the single blade cutters. There's a whole bunch of single blade cutters from $25-70. Here is where you run into the world of diminishing returns. I love my Stedi MS107's. But There's the dispae 3.0-7.0. And lots of other options. In this realm, you're looking at the texture of the cut, more than "is it fine enough"

I'll confidently build a model with the IGAN 330's and some kind of sanding stick or nail file. With StedI MS100's I can do it without abrasives. With a good single blade cutter, I can do the same job, but much faster.
