It looks like second gear, throttle, rear brake, friction zone and practice is the only way I'm going to get comfortable with this on what I'm riding now. Thanks for setting me straight.

don't try to pull away in second, you'd have to slip the poo poo out of the clutch to get moving. practice your throttle vs clutch control and modulate the clutch to keep the revs up

That's what I meant. Why does it always have to rain when I really, really want to ride?
get some rain gear, basic plastic jacket and pants sets work great, and go ride anyway, just brake earlier and less aggressively and don't be hamfisted with the throttle.
try to get a rain jacket with a detachable hood though, the roll up ones are uncomfortable on your neck with a helmet on and a hood flapping around behind your head is really annoying

Woah, middle and ring feels really wierd. I do first and middle on the brake and ring and little on the throttle when I have to. I've had far too much practise finessing brake and throttle at the same time, my bike loving hates starting in the rain and will stall when pulling away idle if the engine is cold and it's raining so I have to keep at least some power on whilst clutched in and braked.
turn up your idle speed a small bit, and try giving the coil, HT lead and spark plug cap a shot of silicone spray to drive out water.

2004 Ninja EX500
Well, on the way to work today, my bike seem to be running fine, idling at 1250rpm, when suddenly it decides to idle really lumpy at 1000rpm, and dies. I can start it up, but only with choke, and I have to hold on the throttle to keep the idle high enough to prevent it from dying.

Then it dies while coasting with the clutch out, and refuses to start with just the starter, so I bump start it going down a hill (lucky) and limp to work.

The starter seems to be cranking fine, and I have headlight/oil light/neutral light. The fuel is low but I can see some in the tank. Switching to reserve petcock made no difference.

This is probably the coldest I've ever ridden the bike (about 55 degrees F)

Any ideas what's wrong? If I can't fix it, I think I'll have a friend of mine come pick me up with his truck.

most likely carb icing, you can get fuel additives that help prevent it, if your bike has carb heaters fitted check that they're working.

Is there any way to get more power out of the charging system? I installed some heated grips, and they work pretty well at above ~2500 rpm. The problem is that they have some battery-saving circuit that cuts them off when the voltage drops below 11.5v, which it does at idle. So any time I stop for a light, the heat shuts off. Turning it on again means holding the on button for like 3 seconds, and then pressing it 3 more times to get the setting to 100%. Which is kind of a pain.

This is an old bike (82 GPz 550), so I'm guessing I don't have many options, but any ideas would be helpful.

a relay will work fine in your case, but if you're at the limit of what your bike can supply switching to LED tail lights and indicators can free up a few watts.

Whoa. Wife Turds posted:

If you're late for work you can give it more throttle when starting before you let out the clutch and let the clutch slip more as you release or ride it for a minute or so with it choked, but neither are particularly good for the bike.

riding with the choke on isn't great for the bike, excess fuel will wash lubricating oil off the cylinders and accelerate wear, i don't think you'd notice it for a long time buy why risk it, however slipping the clutch isn't harmful, its designed to slip.
if the bike is slow to warm up a jet kit or even a bit of fiddling with the pilots could help.

As soon as I pulled the filter I noticed some white frothy poo poo on the bottom of the crankcase breather filter.

I checked my coolant and it's green as green can be, I had to stop myself from drinking it it looked so good. I have yet to drain the oil for the winter, I'll do that tomorrow I think, but could cranking the engine with no gas cause some froth into the breather?

I have a 2005 Ducati Monster 620. I changed the oil just under 1000 miles ago.
When I got off the bike today, I noticed a white spot on the oil sight glass and moved in to investigate.

I initially thought it was on the outside, but it is definitely on the inside. It appears to be a thick, white substance in there with the oil, but I haven't noticed it until now.

When I changed the oil I was concerned about the levels and triple checked it. The oil level still displays right in the middle of the two marks on the sight glass, but there is certainly something in there.

I just got home and looked at it again, and there were bubbles in the oil, like it was foaming up, which I've read can be caused by too much oil, but I know the level is right, and on top of that I changed the oil 1000 miles ago, and I just am now seeing this.

What is going on? Any ideas?

Edit: I forgot to mention that the bike seems to be performing beautifully. Nothing but the white spot on the sight glass would indicate anything is amiss.

like i posted earlier for someones SV650, its probably this, seeing as the monster is air-cooled so there's no head gasket to fail and leak coolant into the oil.

Okay, I worked on that while riding today. I'll have to admit that if I go with one shift every 10 mph or so it does make accelerating easier and faster. I tooled around town a bit in third and fourth. Oh and one shift every 10 mph is around 6k rpm at each shift. I could hold out longer I guess. I'll have to mess around with it and experiment. The bike is much louder if you keep it at high rpms all the time, but it's still much quieter than most bikes I've seen. I met a guy on an R6 today while fueling up and his bike was loud as gently caress.


You need to rev the gently caress out of that bike, plain and simple, bang it off the limiter a few times to see how much you can rev it, i think you'll be surprised.
i've never ridden a ninja 250 but my old bandit 250 (inline 4 not a twin) redlined at 17k, i imagine the ninja redlines at about 14k, so you should be shifting between 10 and 12k. adjust down as appropriate.

edit, thats for hard acceleration/fun. just pootleing around in traffic shift whenever as long as you're not lugging the engine.

How do people handle switching to reserve while in motion?

I ask because today I hit reserve while on the motorway, as usual I didn't click on to the intermittent loss of power in time and my poor baby was going BRHMMMMM POOOOOOOOF BRUMMMMMFFFFFF while angry motorists were wooshing past me in the other lane.

Should I flick it on to reserve if I estimate that I'll be running low ahead of time? (ie BEFORE I get on the bloody motorway?) Or should I go for the gusto and reach for it? Is this something I should practice once in a while to get the hang of it?

Kind of a stupid question, but I was making GBS threads bricks when it happened.

i got into the habit of shutting off the petcock on my f650 as it has a leaky float. took a few days before the habit of switching it back on became ingrained in me. as it turns out there's enough fuel in the bowls to get me about 500 metres away from work and about halfway round a really busy roundabout before it starts lurching. not fun.

My '99 SV650 has been making some noises. When accelerating from a stop, there's a pop/click that comes from the back end. I can feel it a little with my butt, but moreso with my feet on the pegs. It SOUNDS like something is hitting something else, but it only happens within going from 0-15ish. There's from 1-4 of this pops, and it's scaring me. It happened in both 1st and 2nd gear.

Bike is a 1999ish Tomos TTLX, Two Stroke, 50cc moped.

Help!

I got the carb apart today (holy poo poo it was easy to get to! Thanks Tomos engineers), and I am amazed the thing was even idling with the choke. There was grey and brown poo poo caked EVERYWHERE in the carb. Absolutely disgusting.

I cleaned the carb pretty well, put it back together. It would start (with choke on) run a little (with choke on), and run for a second (with choke off) before choking out an dying.

I figured I didn't clean it well enough, and that something is causing it to run out of gas (which as it would die after 3 seconds or so of full throttle, indicates to me that the bowl had been completely bonked dry).

So I cleaned the carb again. Jet had clogged up pretty badly, so I cleaned that again, as well as sprayed the gently caress out of the carb. Same issues once everything was put back together.

I rode one of my Kinetic TFR over to Advanced Auto and picked up two new cans of Carb Cleaner, as well as some little picks (I can't remember what they were called, but they looked like dentistry tools). Rode back, took the carb off.

I took the picks and scraped all the gunk out of the carb, then sprayed it down like riding mopeds was going out of style (:smith:) and put it back together. Same issue :fist:.

Anyone have any ideas on what could be going on?
Thanks

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?

this just happened to me too, new R/R (well an old one pulled off a gsxr400) sorted it, although i have a misfire in one cylinder when it heats up aswell, possibly a faulty coil. need to fix that asap, sick of driving the car

My friend's 1993 Honda CB400 Super Four had a problem with the old battery not charging. I reckoned it was either because of a dodgy battery, not being giving enough time to charge (he liked starting it up in the garage since he cannae ride it atm) or the charging system being faulty.

So I checked the charging system (using the ever reliable point at garage door, rev bike and see how bright(er) the light gets), seemed to be working, so we bought a new battery. Seemed to be all fine and dandy, with maybe a small amount of hesitation sometimes when starting after lots of short trips.

Then the bike decided to die when he was pottering around the local estate, and the worrying thing was that it wouldn't bump start plus the battery was too low to even turn the starter over, so we pushed it home and put it on charge.

Just wondering if it's likely that the charging system is working, but not well enough. Been mighty busy at work, so not checked the bike since we put it on charge. Really got to cram it into his brain not to run the bike in the garage. Hopefully that will soon be a moot point, he's doing his DAS now (mod 1 tomorrow).

The r/r is probably hosed, check the stator output and resistance, and do a diode test on the r/r. Its unlikely to be the stator so your best bet is to ring round bike breakers or trawl ebay for a new r/r.
Pretty much any honda (or suzuki or yamaha) r/r that has 5 wires will do, the only difference will be the connector blocks and the mounting holes.

Also I just noticed my rear tire is basically bald in the center. Ordering a new set of tires now, praying they get here before tuesday so I can get the rear mounted before I leave.

SV's are no fun in ice, too much engine braking.
I was commuting to work in icy weather last winter and it sucked, like plasticsun said throttle control is a must, getting on the gas too hard or chopping the throttle shut can break the rear loose.
Braking is all about serious forward thinking, if you have to emergency brake you're going for a slide. I was using really light front brake and relying more on the rear brake and engine braking combined with clutch modulation to slow down.
I remember going sideways down the road one morning, straight towards a T junction and praying there was no traffic coming along the main road after having to brake hard to avoid some oblivious schoolkids who decided to cross the road right in front of me. luckily I was going slowly to begin with so I just held the slide till I came to a complete stop and puttered off again slowly. Once the roads were gritted it was ok but they only grit main roads here, so smaller backroads and roads around housing estates are treacherous.
I fell once in the yard at work on a completely innocuous looking bit of tarmac that had black ice on it, picking a bike up when you have barely enough traction to stand is the loving worst.

at higher rpm/warmer temps it worked fine.

the electrolytic capacitors on the b400 ecus are known to fail, its tricky but they can be replaced, is yours a vvt(red engine top) model or a normal one? I have an ecu from a vvt lying around if you want it. i may also be able to find a gsxr400 ecu which should drop in.

Also the orings on the pilot screws in the carbs tend to go, and they are really hard to find these days.

I've been a long time lurker in CA and am finally seriously looking at getting a bike. There's someone locally selling a 91 gsf400 bandit with 18k miles for $1000. He had it listed last week for $1400, but the ad says he tried cleaning the carbs and now it won't start. Assuming no other issues with the bike, could someone with no real wrenching experience realistically expect to get the bike running again? Part of me says for a $1000 bike its worth the gamble, the other half says that if it was an easy fix the seller would take care of it for another $400.

id avoid it, those carbs are bastards and you dont want that heartache for your first bike. the b400 is a really nice looking bike but parts are hard to get these days. apart from carb issues the cdi fails a lot on them.

How badly did I gently caress myself here?
you'll be fine, unless you lost any of the acid in the cells. just charge it and stick it back in.

Speaking of this what the hell was Honda doing for 10+ years making bikes with lovely rear end regulator/rectifiers?

bikes in general have lovely r/r's its only recently that decent MOSFET ones have become the norm.

Oh yeah. It's a 1998 Honda CBR 600 f3. I don't own a voltmeter, but I guess I should invest. What am I looking for when I examine the voltage over the battery?

So, I rode through hurricane rains today. Both the bike and me got incredibly soaked. Anyway, after going through a massive puddle that covered both me and my 2001 SV650 in a massive splash, it proceeded to refuse to idle until it stopped raining. Now it's back to idling fine, but I burned so much gas having to restart it, give it some throttle at stops, or just put on the choke to keep it going while it was soaked.

Why would it not idle when soaked? I'm going to be checking electricals first, looking for possible exposed wires causing some sort of misfire. I have no idea how it could go from not idling at all to idling great just by drying out.

SV's drop the front cylinder a lot in heavy rain, making the bike a 322.5cc single. Check that your front spark plug drain hole is clear and give the wiring a spray with a water dispersant/coat of silicone.
a fenda extenda or a diy spray shield just under the radiator will help
