I've had really good luck with 3M Super Weatherstrip adhesive. It's basically super strong contact cement. That and some of those big metal paper clip things to hold it in place while it dries.

*shines Nerobro light on cloud*

Got my bike out for the first ride for two months and it's acting up in the mid range. 1st and 2nd it will pull through the revs no problem but when I hit 5-6000 in 3rd it quits making power and sounds a bit like hitting a rev limiter. I can go through the band at lower throttle, this was at or near WOT.

It "feels" like it's running lean but I don't know for sure. Raining a bit too much right now, so will just theorycraft a little bit. I cleaned and reoiled my filter, maybe I used too much oil? Wouldn't it act exactly like that if the air is restricted? There's no popping or backfiring at any rev / throttle position.

Otherwise I'm thinking simply carb cleaning after sitting for a while, althought that would mean dirty mains but clean pilots as it's completely a-ok in the lower range. Float height is another thing, maybe it's lean after all? I'll also get a Carbtune synchronizer a soon as the moths stop flying out of my wallet.

Lastly, fuel starvation. My hoses aren't too good, I'll be getting new ones this weekend or next. I also heard some sediment moving around in the tank when it was off the bike so maybe the petcock filter is clogged. But then again in isn't clogged enough for the bike to stall it's probably flowing enough for normal fuel delivery anyway.

Since the bike starts and idles fine, I'm betting it's an intake restriction.

Over oiling the air filter will cause an intake restriction. That will make the bike go very, very rich. And behave exactly as you're describing.

Meh, I wouldn't be very worried about crap in the tank. I've only once seen a tank filter so clogged that it wouldn't flow enough fuel to make the bike run right.

Replacing the fuel hoses every couple years is good measure anyway.

I think that's one of the easiest patterns to do with an airbrush. You could buy one with some paint and practice on smooth sheets of wood for a while. Then go ahead and suck your own cock.

Otherwise I'm not sure how much it would cost. First thought is that custom paint is very expensive. But then again there are shitloads of airbrush artists out there and an abstract ripple pattern might be easy to get right, as it's pretty hard to tell if anything's wrong.

I like the idea too, would look very cool.

What does a normal clean/freshly lubed chain sound like? I cleaned all the gunk finally off my chain to make it pretty, and now something on the bike makes a quiet raspy/sizzling style of sound maintaining speed or right as you accelerate from a given speed. Too high pitched to be an exhaust leak and not coming from the right area. Chain noise would make sense but all I have heard in the past was a dirty chain covered in chain lube.

Try putting it on the ceterstand if you have one, start it and put it into gear then walk around it trying to pinpoint the noise.

You don't need to even have it in gear - as long as the bike's cold, there will be enough force going through the clutch to spin the back wheel in neutral.

Ask me how I know... :smith:

The mechanical/sizzling sound is roughly what a nicely oiled/cleaned chain should sound like. Just make sure it's adjusted properly, and you'll be fine.

Okay, so here's my situation right now in brief:

I have a 2001 SV650S

My bike's had problems with starting for a while. The battery would occasionally be too weak to start (espceially in colder weather) even when the battery was new and I was keeping revs high. Hell, even now it won't turn over with a perfect, fully charged battery and the trickle charger hooked up to the drat thing.

It was suggested that it could be the R/R, so finally today I got around to taking the cover off and doing a diode test with my multimeter. Here's what the manual says:



The one highlighted in red (B/W+, R-) was out of spec, reading about .95V. All the "1.5" readings also showed no change on the multimeter, but as I understand it those are testing for current leakage in the other direction, so they shouldn't affect the reading anyway right?

So what exactly does the .95 mean? leaky diode? Do I have to buy a new R/R?

Wait - even with a fully charged battery it won't turn over?

That sounds like either a starter issue, or corroded wiring.

funny, this was just discussed. :-) I tend to test thigns the other way. the r/r is a black box. If everythign else is ok, then the r/r is hosed.

on the three prong connector on the bike, check the ohms leg to leg. If they're all the same, that's good.

But you said the bike isn't starting at all now. Check the battery. What's it's voltage? Does it crank over at all? Have you checked the fluid level in the battery?

The BW line, is the ground line for the r/r. The red wire is the positive wire. You can use the voltmeter to test between the red wire on the plug, and the red wire on the battery. There should be less than 1ohm. Same for the black-white wire, to the black wire on the battery.

So maybe the starter relay then? I haven't checked that.

The engine used to crank over weakly, but wouldn't fire, now the lights just dim and I hear nothing when I hit the starter button.

Battery voltage's about 12 or 13 volts if I remember correctly. Around there. It's a sealed battery, too.

You need tocheck the voltage while cranking. A shot battery will get to 14v charge, but as soon as you put a load on it, the voltage will plummet down to the low single digits. You probally have ruined your battery in the process here.

Well if the lights are dimming too then it's most likely a dead battery.

Try hooking up a car battery to the terminals, careful not to short the positive side, and see what happens.

Figured as much but didnt expect it to be as loud as it was. On a road bike it makes a similar sound only if your head is next to the chain while cleaning it :v:. This you can hear over road, engine, and wind noise going 70.

I assume you put on new sprockets as well. Until the sprockets wear to match the chain, you'll have lots of that sizzle noise. Now I've got a few thousand miles on my 83, the noise has gone away to a certain extent.

Yes, it's normal.

This is the old chain/sprockets which I believe is original. Sizzle noise only came after the cleaning to take off about 3mm of gunk covering everything.

Grease makes a great damping material. Chains go from noisy when clean, to quiet as they get coated in grease, gunk, and other nasty stuff. And then noisy again when they start destroying themselves.

That black crap that builds up on your chain, is something like 80% rubber that comes off the rear tire.

I have a '99 V-Star 650 with a leaky fuel-shutoff valve. I was already in the habit of shutting it off while parked as a precaution, but lately it has started to actually leak in a slow drip while it's turned on. Very annoying.

It can't be that complicated to fix myself, aside from draining all the fuel out of the tank, right? I guess I'm just nervous because I don't have access to a garage or a lot of tools, so the repair (my first on a motorcycle) would have to be completed in a driveway. Looking at online parts diagrams I would imagine all I have to do is replace some valve packing, though, which seems simple enough.

Would I be opening a can of worms?

thanks!

Even for a complete noob, it should only be an hour job. Easiest solution is to buy a complete new petcock. Replacement is as simple as removing the fuel and vacuum lines, then unbolting one petcock, and bolting on the other.

There are rebuild kits,which are much cheaper, but require some skill to install.

You probably didn't come off the throttle completely, or fumbled the clutch enough to cause some driveline shock. Not bad enough to cause a missed shift, but enough to cause the transmission to come together harshly. Not a big deal, it happens sometimes.

Sometimes I get a louder clunk when shifting. Haven't noticed it when upshifting - usually downshifting. I assume its either the linkages catching just right (or just wrong), or as Z3n said, a slight mis-shift.

I wouldn't sweat it unless it starts happening constantly, or you start noticing slipping.

It would mean that the clutch wasn't engaging fully, and the clacking into gear is resulting from that. You're likely to notice that clunking more often when your bike is cold, before the oil's had a chance to warm up.
