No. You might find it easier to do in second gear, though. The engine doesn't need to be turning quickly in order to start, and being in second when the engine catches makes the bike more stable.

Ah okay thanks. I can see it definitely being easier in second, because sometimes first gear just locks up and slides. Not so much on the V, but on any dirtbike I've tried it with.

But it's voltage, not amperage that determines how fast the starter will spin

Yeah. Any 12 volt battery can be used to safely run any 12 volt electrical system. A battery that's too small may have problems sourcing the current needed to spin the starter, but one that's larger than necessary is only bad because it's adding weight. No danger.

I could give the H-D guy the benefit of the doubt and believe that he thought I had a 6 volt electrical system. In that case, he was right that a 12v battery wouldn't be suitable. But I don't think that was his reasoning.

haha even in the olden days you could throw a 12v battery on a 6v car and sorta be okay to crank it. it'd blow the coil/lights/radio, and eventually the starter, but it'd crank fast as gently caress.

Running all the way back to the beginning of jumpstartchat: I ended up bump starting it instead, since my dad showed me how and there's a perfectly sized hill right at the end of my driveway.

Coughed for nearly two minutes while the electrics tried to work out whether to favour the headlight or the sparkplug, finally revved up properly and then immediately had another coughing fit when I stepped on the brake :v:


Basically it just needs a couple hours of high revs and no stopping whatsoever, ie motorway. Probably more than a couple tbh but that'll be enough to get let it not die idling at traffic lights. I could just rev it in my driveway I guess, but gently caress that boring noise.

Put it up on a stand and put one of those cruise control things on it. I'm sure nothing can possibly go wrong with this plan.

Am I missing something, or does my fuel tank not have a shut off valve? And if it doesn't have a shutoff valve, how was I supposed to get it off the tank without leaking gas everywhere?

This is the underside of the tank.


One of the two black lines has this plastic bit in the middle, but otherwise both are connected directly to something in the engine.

Do you have an electric or vacuum actuated petcock?

That's a fuel injected system and those are quick disconnectors on the fuel lines which should in theory shut off when they're disconnected. If they don't then the only solution is to find something to shove in there to plug it or disconnect the line somewhere else that does allow you to plug the line.

I had to unplug some wires from the tank before it would come off, so probably electric (read: I have no idea).

Most of them until about the mid-seventies (and a lot of them right into the eighties), I believe, although an electric drill connected to the speedo cable was the preferred method.

(e: also using a drill to run them all the way round the clock works on every analogue odo, obviously)

Came here to post this. Incidentally, diesel vehicles here pay tax based on miles covered so now all the olden diesels with cable speedos are in massive demand because you can drive all year then wind back the odo to show you've only done a few hundred km's and only pay like fifty bucks tax.

Its big business clocking cars on the second hand market here. although now the annual inspection includes the mileage on the cert, so that at least sets a minimum value that they can reset to. That presupposes that you got a valid inspection cert in the first place though.

There is actually a surprising amount of security involved but yeah, most of them are breakable. The point of most of the security is to just make it preferable to target some other brand's cars. Actually that's applicable to most security, of course.

(I remember a documentary a few years ago about it and they had one of these reformed ex-fraudster types talking about all this stuff, and he mentioned off-hand that VAG had particularly good security - I wonder why they would be so keen to keep people out of the ECU?)

My bike had a little issue starting the last couple of days, taking a few revolutions to catch. I figured it was the cold messing with the bike but today I learned that there wasn't enough juice 20 miles from home. Thankfully my brother in law is an ace pusher and helped me bump start. I've been riding the bike to and from work and I was riding the bike the entire saturday, most of them highway miles, so the battery wasn't flat from disuse.

It's either the charging system of my battery. what are the smart steps to take? Jumpstart the bike so I can measure the voltage output at ~3000 rpm and if that's 14~15v I know the battery is shot? That that sound about right?

edit: Also I've learned that bandit 1250's might have a problem with exploding starter motors. Good to know I guess, that gives me much hope for the future.

I bought a new fairing from a guy that came with his display and when I plugged it in to make sure it worked it popped up the mileage for his bike. So, if you're trying to scam someone you may be able to just buy a new display. As long as you have the same bike I do.

Yes exactly. I buy the cheapest batteries and store them poorly. They fail like you said, a few days of slow starting and eyebrows curving, then the engine stops running.

Well, yeah, but that's equivalent to buying the gauge cluster out of a junkyard car. You need a bike somewhere that has the lower mileage you want, and that doesn't need its display.

Much more flexible if you can just plug into a JTAG header and massage the numbers a bit.

So, since yesterday the tachometer on my cbr300r has been acting up. It goes up/down fine in relation to RPMs, but basically refuses to go under a certain limit even when the engine is idle or off. What this limit is keeps changing - this morning it refused to go under 6k, then under 9k after a bit of riding, now the bike is parked outside with the indicator at 2k.

Is there a DIY fix to this or is it a dealer job? Shifting by habit and sound still works fine, of course, and there's no other issues as far as I can tell.

That's a weird one really because the only thing I can think of that could cause that would be something like a dodgy return spring on one of the really old systems that used the spark plug circuit to drive a thing the name of which I'm completely blanking on but it's like an electric motor that doesn't actually move.

More modern stepper-motor ones are normally pretty much absolutely fine or completely broken.

You up for some serious plastic surgery?
Pulled apart the front end of my 2011 Ninja 250 in an attempt to remedy my speedometer working intermittently. Got everything apart, documented it with photos, took the gauge cluster out and I think I got a bit of stickiness off that may have been affecting the speedo needle. Since I had the front end opened up, I decided to get replacement LED bulbs for my gauge cluster. Put them in, some worked (speedo and gas tank light, turn signal) but the others didn't light up. Figured it was since I didn't have all the wiring re connected. Really the only wiring I even touched was the headlight wiring and then disconnecting and reconnecting the gauge cluster.

Got everything back together, and uhh, here's what still works. With the ignition on, the cluster backlights come on. Turn signals work in the front, back, and the indicator works on the cluster. Brake light works. The horn works. HOWEVER, I cannot get the bike to start. Putting the kill switch into ON and pressing the starter button does nothing, either with the kickstand up or down. I cannot get the neutral light to engage on the cluster. Headlight will not turn on.

Not really sure what exactly I did wrong here, I didn't mess with any of the electronics going to the starter or ignition. The bike does have an aftermarket Bike Master Xenon HIDzzzz headlight with some additional ballasts that the PO installed. Any ideas on what I can try to do and troubleshoot this? Am I safe to assume that it's probably not the battery given that some of the electronics work?

e: At least, from what I can tell, no. Since the neutral indicator light isn't coming on I guess I can't say with 100% certainty that I'm in neutral, but it sure feels like it.

If the neutral light isn't on, it's likely that the circuit handling the neutral-switch starter cutoff is also not working correctly. Can you start the bike in gear if you hold in the clutch?
