Battery terminals, ignition switch/relay could be faulty, starter could be on it's way out, but start with a new battery. Often wiring or relays get hot and stop passing current, then cool down and everything is hunky dory again.

Bad batteries tend to act weird, not just decline linearly. But that does seem a bit too weird. Following up on the above, measure the voltage across the terminals when cranking. If it's the same good and bad, then something else is wrong. Occam's multimeter still indicates bad battery. They too change with temperature, it might be cranking worse when it's hot.

Talking about batteries, I use one of those batteries you fill from the included bottles and then pound a seal into. My battery almost lies flat so in retrospect it wasn't recommended to use one of those (instead of a completely sealed one) but it did fine for months. Now just today I took my seat off and noticed tiny yellow particles everywhere, looked exactly like pollen. However upon closer inspection this seemed to have originated from the battery; on the battery itself there was some chalky white residue below the seal, which had corroded the battery box, and some fresher-looking foamy stuff also, however strangely that was at the top lip of the seal (you'd suspect any fluid to leak downward). I can't find anything about this happening to other people, any ideas? Of course I'm buying a completely sealed battery now.

Battery fluid bubbles when it's charging. It'll seep out of the seals and the drain on the side, and leave residue when it evaporates. Laying it on the side probably exposed the plates inside, which means they sulfated, and probably put even more solids in the fluid as it leaked out. So as far as I can tell, my heat problem isn't the battery. I swapped for another bike's, which has never had a problem, and the same thing happened. Pulled and disassembled the starter motor, it's pretty filthy, and there's dust from the brushes or magnets and some greasy residue all over the rotor. Cleaned it up, polished the copper part the brushes ride on, and reassembled. I'll test ride tomorrow. Really hoping this is it, but next step is an actual new battery, then a starter relay.

My battery almost lies flat so in retrospect it wasn't recommended to use one of those (instead of a completely sealed one) but it did fine for months. Those self-filled batteries can be sealed units too (the Yuasa I'm using is one, for example), and sealed units may still not be suitable for non-upright mounting. Normally though if it's a motorcycle battery that has to be mounted upright it'll say so in pretty massive letters on the battery itself - it's possible that your battery was fine for mounting where you put it but you didn't actually seal it properly, or that it just had a manufacturing flaw. Even non-sealed batteries shouldn't fail like that though (instead you should have just got electrolyte pissing out the vent tube as soon as you installed it) so I'd double-check that your regulator is working properly if I were you. Also make sure you clean out the battery box and surrounding area with plenty of clean water.

Thanks. I checked the regulator and it's fine, voltage stays within the 14v range, so I feel confident enough about trying a new battery.

Did you overcharge and gas the battery? The 3-phase charging system on the earlier models is better than the single-phase they went to in 08 so I wouldn't suspect the VR either. If you're losing headlights, that's a sign the VR is going.

So my neighbor's 69 Guzzi Ambassador has a noticeable repeating clunk coming from the rear drive, only when rotating forward. Is the bearing that supports the drive shaft going into the hub just bad?

Good thing. https://www.youtube.com/watch?v=M3MfLcJLaCs Not really a fair comparison (though both tests are full brake application so fair in that sense), I'd rather see real braking instead of just flat out locking the brakes up for the non-abs test, but still shows how quickly it goes down, and how impressive the ABS is. People who rail against ABS are the same people who hate any modern technology because "Back in my day  ".

Can anyone recommend a shop in the Austin/Round Rock area to work on my SV1000? I'm getting a weird surging/hesitation when I sit at constant throttle. It seems to be strongest in the 3-5k rpm range. Alternatively, can anyone offer any suggestions? It sounds like the engine misses a bit, then extra power comes on. Under engine braking, it's smooth, if I open up the throttle it seems to accelerate smoothly. It got a new chain and sprockets a few months back. I recently cleaned and lubed the chain, and it seems to be good. I think it's a fueling or valving issue or something.

Tanbo posted:Good thing. https://www.youtube.com/watch?v=M3MfLcJLaCs I've always assumed people who rail against ABS (and I was one of them for a while) are the same as those who railed against EFI in the nineties - because the first generation wasn't perfect, it can never ever be perfect. Of course with ABS you've got the added spice of "I'm far better than any box of tricks, I don't need no computers telling me when to brake", which was the main reason I opted not to get the ABS on the Shiver, a decision I've been fortunate enough not to have seriously regretted yet, although I have locked the front in the dry more than once and immediately thought "poo poo if it had been wet..."

I also agree it should be switchable (though it would be simple to add if the owner desires). I have yet to have ABS save my rear end, though I've had it chatter a bit on the rear a few times, nothing that I found to be intrusive.

I was suspicious of the shop that put the tune on, and flashed the standard tune for my bike/pipe combo last night. I also redid the tps calibration. Problem is still there. I was riding with the shops tune for a few months, the problem didn't start till a couple weeks ago and has progressively gotten worse.

I checked the voltage regulator, ~14.5v. Stator gives 16v per 1000rpm, no shorts to ground. I wish I was 100% sure what happened because I don't want the new, much more expensive American Made battery to blow up as well.

I don't expect an older non-sealed battery to stand up to much signature vibration. The Bar&Shield batteries have bigger/sturdier posts and don't cost any more than a generic sealed unit from Batteries+ or whatever. I brought the original from my Uly into a non-Buell HD dealer and they had a replacement in stock ready to go. If you go that way, make drat sure the polarity is correct - sporties use the same size/cca battery but the posts are reversed.

ABS has saved my rear end, or at least come close to it. I was hooning out of an alley once and didn't see a car making a fast right hand turn in time - there was a bit of mud on my rear tire, too. I gripped the front brake as hard as I could with the two fingers that were up there, and the ABS shug-shug-shugged its way into my heart.

Yeah I've heard of a handful of cars that require a diagnostic tool to cycle the ABS pump when changing/bleeding fluids, but that seems to be pretty rare. I've also heard you can bypass that procedure by braking hard on grass, but I'm not sure how well that would work out in reality.

I've also heard you can bypass that procedure by braking hard on grass, but I'm not sure how well that would work out in reality. I wouldn't recommend it, but the only cars I've struck that couldn't be bled manually have been the brake-by-wire toyotas and similar. It shouldn't be an issue on bikes I wouldn't think, as bikes haven't got any kind of brake servo system at all. Not to mention, as with all technogadgetry, twenty years after it's come out some clever people on the internet would've figured out exactly how it works and how to work on it and what seemed baffling and cutting-edge when it was new becomes quaint and outdated. BlackMK4 posted:You're going to eat poo poo when you ride a bike without ABS. Yup. But that might never happen unless he goes out of his way to buy one without.

Has anyone played with that new BMW ABS system that also stops the bike standing up if you brake hard mid-corner? That seems like the next stage of ABS systems (well that and the "lift mitigation" that Aprilia have put into APRC that makes backing the bike in GP-style a piece of piss)
