It's odd that there's no noise when you spin the front wheel off the ground (I assume you've done that since you say the bearings are fine). So maybe something is rubbing only when there's weight on the bike? Also are you certain it isn't keys on your keyring bouncing around? Not much else to go wrong up front really.

I mean, it sounds to me like the sound comes from the front end, but then again, that's where the window of my helmet is. I had the front wheel off today and checked the bearings by hand and they turned smoothly. I don't use a keychain either. I'm running out of moving parts in general to pin it on, so I'm thinking it has to be the final drive. You're right though, 50 mm is a lot of slack, even if it's within spec, and there's a couple places I can think to check tomorrow to see if it's rubbing on anything.

Is that not a spectacularly bad idea? It sounds like a recipe for a hilarious disaster. (Bear in mind I know next to gently caress all about performing bike maintenance!)

I guess WD-40 should help get random oil off, but what about getting some nice looking cooling fins? Wire brush? I use a wheel brush with plastic bristles, bottle cleaner, soapy carwash water, and/or simple green to tidy up my engine. It's a tedious hand wash and I usually puncture or scratch my hand on something pointy but it gets the job done. The bike looks OK dirty though, so this is like a 1 or 2 per year sort of chore just to make it so I don't hate working on it.

Hey, just fuelled up there and the bike wouldn't unlock, so gave the key a thump and it finally turned. After that, steering was sluggish like it was partially locked (would still turn the whole way, but the bike was wobbling like gently caress if I made minor course corrections), I've locked and unlocked it and it's slightly less sluggish but you can still feel it. Should I unscrew the lock and pop it in again? e: Possible other cause is that I had a tank bag that I yanked the strap of round the steering column taut before I set off again, but I wobbled over to the side of the road and undid it and the steering was still acting up. Can't think of any hydraulics that I possibly pinched that would affect steering, other than the front brake but I think that would have been more noticeable given it's got a warped rotor that I haven't replaced yet.

Ok, I replaced the roller and tightened up the chain and it fixed the dumb chattering squeakiness. The chain was rubbing on the plastic cover of the countershaft sprocket when the bike was under load. The label on the swingarm says to allow 40-50mm of chain deflection, which is what I was within. The manual, however, says 35-45mm, so I took it to 35 and that seems to be the difference. It's quite obvious now that I looked in the right place.

I think he wanted more info on the "typical Honda R/R" issues. If not, please tell me more anyway. I replaced my old Suzuki rec and reg with a newer Honda R/R (from an '09 CBR IIRC) based on a lot of material suggesting that R/R offered a big improvement over Suzuki's old and retarded charging systems. Both could be true, as even with "typical issues" the Honda R/R could still vastly improve charging over the old-Suzuki set-up (seriously, the GS stock charging system in the 70's sucks donkey dick). So what's up?

All older motorcycle r/rs are poo poo and often placed on the bike where they don't get adequate cooling. certain hondas were notorious for r/r failures. if and when it goes just replace it with a modern MOSFET based one. I think yamaha were the first to change over as all the old threads talk about swapping in an R1 r/r, but there are lots of sites selling them now http://motoelectrixcom.myshopify.com/products/shindengen-mosfet-fh012aa-regulator-rectifier-kit

I'm pretty sure on my old '01 F4i it was tucked up inside the tail plastic which was a bitch to get on. I can't imagine it was getting any kind of airflow in there. It never took a poo poo on me but I could see it ending badly.

So our next door neighbours moved and sold us their 1974 BMW R60/6 for $1. This isn't the exact bike, but it's the same bike so here have a picture of this bike.  They said that it ran just fine the last time they started it... In 2000. Are there general rules for what I should do/have done to this bike before I bother trying to start it if it hasn't been ridden in like 10ish years?

So will the tyres (they will have hardened up, even if they have plenty of tread). If they weren't drained before it stopped moving the carbs will need stripping and cleaning and you definitely want to get any gas out of the tank and throw some seafoam (or redex) in the first tank of fresh fuel. Change the oil and filter. Other things Check the valve clearances (super easy on a boxer!) EDIT: probably want to check the spark plugs too, again, super easy. Brake pads/fluid/ almost definitely, even if they "work". Brake lines maybe too. Cracked/hardened carb boots and other rubber stuff like fuel lines etc. Check the condition of the control cables, clutch especially.

I might be able to work it on the old horn mount, but it's huge underneath the headlight.   Other option is hanging it off the side where the old fairing mount was, but that would be even worse I think. It'd be like a big ugly mole.

Just had my first putter around a parking lot on my friend's bike. It was awesome, but I think I'm having a problem overcoming the "oh duck it's gonna fall over, lean the other way! Oh gently caress it's turning, it's gonna fall, LEAN THE OTHER WAY why is it turning again ahhhh" thing. Heh. Basically how do I get over the feeling that the bike is going to topple over at any given second?

Basically how do I get over the feeling that the bike is going to topple over at any given second? More throttle. The faster you go, the more the bike wants to go in a straight line and stay upright (to a point). Get confident riding around the parking lot at about 20mph, then work on low-speed maneuvers afterwards. Also, it sounds like you're trying to muscle it around by leaning your weight or something. This is a failing proposition on a motorcycle, which (hopefully) outweighs you by at least a hundred pounds. Controlling a motorcycle is a lot more like riding a horse than a bicycle, in that you can't easily "steer" it -- you sort of gently indicate where you want to go and the bike goes there itself.

Basically how do I get over the feeling that the bike is going to topple over at any given second? Riding a bike slow is one of the hardest things to do. Some tips: - MSF or local equivalent. No, seriously, do it. - always keep the drivetrain under tension. Use a bit a rear brake if you must. - LOOK WHERE YOU WANT TO GO. Looking at the ground in front of you means you're instable. Looking at your handlebars? Same. If you want to go around a corner, crane your head like an owl until it hurts. Then turn some more. - Balancing at low speed is an act between your throttle, clutch, brakes, body position and steering input. All of them affect balance, so they are all an option to keep it. Try to keep input to a minimum. - Learn steady throttle, especially when turning. It is harder than you think but will help immensely with the former tip. - You've done the MSF, right?

Is a faulty r/r checkable on a bike without taking it apart? It pretty much handles the charging of the battery right? My checklists as of now consists of: - Does it keep going in a straight when the handlebars are released (crooked frame/forks); - Shutter/stuttering when braking (warped discs); - Grooves in brakediscs; - Pulls cleanly troughout the rev range; - Damage on the frame (crash); - Sprockets and chain (pointy teeth/shape on the sprockets); - Should not make any sounds on idle when the clutch is pulled in (camchain tensioner?). There's another thing to check for play in steering bearings but I have no idea to check that without putting the bike on some sort of stand. Also read alot of stuff about false neutrals which was supposed to be specific for the 929. Are there any other used bike buying tricks you guys know of? Apologies for the Dunglish.

False neutrals are more of a user thing than a machine, most new bikes (80s forward) you shouldn't really get them unless you stuff up (e.g. forget to go up that little bit higher from 1st to 2nd and get it in Neutral D: ). Check the forks aren't leaking as well before you pick it up. Oil above the seals.

jujube posted:Is a faulty r/r checkable on a bike without taking it apart? It pretty much handles the charging of the battery right? Yeah, just start it up and measure the battery voltage while varying revs. I think the ideal voltage lies somewhere around 14-15V and if it doesn't maintain a relatively constant voltage regardless of revs then there is likely a problem with the regulator. As for sounds, that's harder to tell sometimes. My ZZR250 had a knocking sound at idle that was apparently normal and 675s apparently all sound like ticking time bombs.
