We don't get the Hilux, we get the slightly different Tacoma, and it costs drat near as much as a full-sized pickup. Resale value is ridiculously good too, so finding decent a deal on used examples in good shape is tough.

Tacoma are loving awesome and have no faults at all which is the lie Tacoma owners tell ourselves to justify paying that much for a 10 year old truck.

Holy crap I looked it up and my dr650 and my honda cb300f have about the same weight. I would never had guessed.

Another question, my battery is going on two years but seems fine. Should I care enough to youtube up the way to check it out with a multimeter? I've had zero problems with but for various reasons I've never personally had a battery last much longer than this one (mostly the bikes broke or got sold).

Edit because I can't do basic math.

If you're asking if replacing a battery preemptively is a thing, it isn't unless you're really starved for something to do/waste money on.

Wait I missed lithium chat, why aren't lithium batteries great? I've had two for a year and so far I've had nothing but success despite abusing them both horribly and doing zero maintenance/charging on them.

Because they are usually made in cheap factories out of subpar cells and old lotto tickets. According to people that have opened them up.

Plus lot's of small cells in series vs a big cell, so you can run into a charge imbalance with cheap cells which is Really Bad.

I like my shorai, though.

Because lithium batteries are great when they are working and taken care of.

When they fail though, they do so with an unquenchable fire that is self fueling.

You shouldn't over charge them, you shouldn't undervolt them, they cannot (CANNOT) be punctured, they are picky things that can be difficult to get right (see Samsung galaxy phones).

When a lead acid battery fails, it just does n start your bike anymore, it generally won't burn it to the ground.

The weight savings isn't worth the risk from Chinese batteries.

I don't think LiFePo batteries have an issue with catching on fire. Maybe you're thinking of a different kind of lithium battery?

Anyway, they're also bad because you can discharge them all the way and then they're dead forever (except, supposedly EarthX which are super expensive but have something fancy that stops them from being discharged all the way and also they self-balance).

I just think they're too expensive for what you get if you have access to a nice toasty garage where you can hook up a tender.

I don't, I have to drag the tender and an extension cord out from my apartment and I can't leave it overnight.

But apparently my lithium batteries either all have excellent smartchip protection or are of superior construction because I have:

- Left the lights on for eight hours, all electrics were dead, charged it for twenty minutes and it was symptom-free. Rode for 15 minutes and parked it with no further charging, continued to ride all summer with no further charging.

- Put the little KLR-sized lithium battery in the Concours when the Concours' giant lead battery died and it ran better than when the lead battery was working.

- Hooked a new Concours-sized lithium battery up backwards in the bike, blowing the main fuse, and ALSO hooked the lithium battery up to the charger backwards at 10 Amps. Corrected polarities, replaced the fuse, instantly symptom-free.

The fiery mode of failure isn't something I considered, but also not something I think is true of modern LiFePO cells?

Either way, for the number of times my behaviour would have surely killed a lead battery, the lithium cells have paid for themselves.

In my mind there are three big negatives to LiFePo batteries. 1. Cost and 2. If you drain them they're dead forever and 3. you need to balance them with a special charger every so often for best life. EarthX gets around 2 and 3 at the price of even more of #1.

What are the other negatives you're referring to, because it seems like your prior post was primarily aimed at LiPo batteries, not LiFePo batteries? I'm not aware of any LiPo motorcycle batteries for exactly the reasons you mentioned, but maybe they're out there.

So I ended up paying a dude to my take my bike away and slap a new tyre/tube on since we were busy as gently caress moving house and stuff, nice guy but he tightened my chain and rear brake way the gently caress up so it was more like riding a horse than a bike on the way home.

However I've still got to address another problem as I've got an exhaust air leak if you could call it that, where basically sound doesn't come out the muffler but instead out the pipe header (it's loud as gently caress which while neat, I imagine isn't very healthy). Is it pretty much a case replacing the exhaust header gasket and making sure the holder nuts are tight enough? the whole thing wobbles a bit since the middle frame clamp needs a new rubber damper which has rotted away.

Alright, I'm working on rebuilding the forks on my bike. I was taught that calipers should never be suspended by the brake lines. I don't remember where I read that. Well, my dad was making fun of me for being so meticulous. He says his mechanic friend never worries about that. What's the truth?

Yes, pretty much. Good to do it sooner rather than later, as the mixture goes wrong and an exhaust valve might burn. Nuts can be tricky to get off. If they won't budge, before you apply gorilla strength and snap them, heat them up by running the engine and try again. Worth a shot as broken studs are a massive pain.

The truth is brake hoses are tested to way, way more stress than a couple of hundred grams dangling statically but it's good practice to tie them back or they dangle around and bash and scratch things that don't need bashing or scratching.

I've been given a crappy chinese 50cc 4 stroke scooter with the usual GY6 pattern engine. It was free and thus I'm using it to teach my missus spannering without breaking anything worth money. If I spend about $100 on ali express I can upgrade it to a 100cc bore/head (the original reciprocating parts are completely hosed). How would I go about working out the right jets to stick in the carb? It's a tiny keihin so getting jets won't be an issue, I just don't know what size to stick in there seeing as it's going to be double the displacement.

Can you extrapolate from their recommendations for overbored dirt bikes? They should have stuff for 250-650, I'd think and you can extrapolate from there as a start.

Arai recommends anything older than 7 years be replaced, even if it's unused. The EPS breaks down over time, and I've never heard of a company relining a shell before.

My brother was given a Chineseium 50cc scooter that needed some parts off Aliexpress, so he spent a fair amount getting stuff shipped to NZ. Turns out he ordered all the wrong parts because none of them fit.

He ended up giving it to our stepfather to blow up in one of these silly charity runs where you ride scooters like 200km and fix them as you go. :v:

I think it lasted 120km before the engine grenaded.

There's an electrical cable that hooks up to my clutch perch. Pretty sure it's a sensor for telling the bike whether or not the clutch is in. If I were to, say, get a different perch and leave this disconnected, would it have any adverse affects? Is it there just so the bike won't start in gear with the clutch out?

Oh lame so does a 50cc bore only yield you 80cc? That's a little disappointing, but for forty bucks who gives a poo poo.

I'm starting to see the appeal of modding scooters but it only makes sense if the scooter is cheap chinese poo poo and everything is forty bucks or less of aliexpress. Have you got a lumpy cam as well? For eleven bucks I'm certainly willing to give it a try.

It's part of the neutral/clutch/side-stand bullshit safety triangle. If you disconnect the switch just join the two wires together somehow and it'll be like the clutch is always pulled in.

Depending on the bike it'll run like poo poo/stall if you don't have a functioning clutch switch, some bikes (such as KTM 690s) use a different map while the clutch is in. Why? No idea.
