I know that this classic bicycle’s wheel—with what looks to be repurposed valve springs in place of a rubber tire—is likely hugely impractical, but I still kind of want to try it out.

You get sprung wanna pull up tough
Cause you noticed that fixie was stuffed -
I’m…actually really curious to see what happens when you try to turn with any level of lateral G. Considering the outcomes I’m envisioning, though, I’m not curious enough to try it myself.

They look slightly conical – valve springs?

So, I made it out to my first autocross event (ever!) this weekend. So, fantastic to get the chance to hoon my car in safer circumstances (sure enough, it seems willing to rotate for a small FWD hatch, even without trying too hard). and I did manage to make progress over my first three runs (midpack in my class at that point). But, by 4 and 5, I found myself pushing a little too hard to overcome an absolute lack of power below 3000rpm, and losing time. I’ll have to learn how to carry more speed so I can pull out a little more aggressively. I’m really hoping to get out again in August at least.
On the bright side, all 5 runs were clean (no getting lost, no cone penalties, and no off-course voidings).-
Autocross teaches you a lot. For example: pulling out aggressively is a valuable skill in life.

Does anyone know why spark plug wires go bad?
I’m working on an old Yamaha that has the plug wires integrated with the coils as one unit. Since the coil-wire unit is NLA, people cut the plug wire at the coil and at the plug connector and solder in a new one.
From what I’ve read, “bad” plug wires have higher resistance. I would normally assume that increased resistance comes from corrosion at solder joints and connections, but the above fix suggests it’s the wire itself that is becoming more resistive. As a chemist, I wonder: How can this be?-
What’s going on is the insulator is wearing out and the power of the electrical current is leaking out in the form of corona discharge instead of arcing across the spark plug.

Magic!
Also, what ^^jeepjeff^^ said up there.-
Honestly, this is sort of what I thought every time someone told me to change spark plug wires on my old crapcans. I put that into the “call on the gods of Jupiter”-category, yet it tended to have a real impact.
So…what’s the regular life expectancy of spark plug wirss?-
It’s cheap insurance, a no-brainer especially when buying a cheap beater or anything of vague provenance, double-‘specially with anything older than… 98? 99? 10 years old? whatever the tea leaves indicate?
Plug wire life varies by vehicle/engine/use/etc. Old-skool points & distributor in a generous, uncrowded engine bay housing a stone-axe straight six, or the last year high-strung twin-turbo’d version before (insert vehicle of choice here) went to coil-on-plug, with EPA-focused super-lean/hot underhood temps? Anywhere from 2 years, to 2+ decades.-
Your answer has me worried about my cables, ha! I might just float through that worry though.

Also depends on whether oil leaks into the plug bores. Even with that under control, my old Accord ate plug wires fairly regularly..

Wet grip is over-rated.

That’s not what she said.

I’m assuming the weight might have increased a tad too!

(Re) coils in horror.
