1975 Honda CB200. It's a dumpster save from the guy who taught me how to work on motorcycles. He used it to learn to ride offroad, and we use it to teach newbs how to ride. It's not in the best condition, it definitely needs some work, but it still starts up willingly on the first kick and is just so much fun to ride.  Here it is with the other bikes we owned at the time...for around town, I tended to take the 200 rather than the 929.  I used to have a lot of fun on it running up and down Redwood road in the bay area and chasing down squids on it. It's also useful as a knee down trainer!  https://www.youtube.com/watch?v=VABQbps8n5w It needs a new stator, (currently doesn't make enough power to charge the battery if the lights are on), new fork seals, new front brake pads, and to be cleaned and had the oil changed. Oh, and it doesn't have working turn signals, or a brake light. Whoops. This bike attracts the most attention out of any bike I've ever owned, we've had people stop traffic to ask us if we'll sell the bike. As my friend says: "An old bike is like an ugly girl...it looks attainable".

I talked to my father today, and when/if the time presents itself, we're probably going to clean up the (maybe) running bike, and part out everything that's not rusted to poo poo on the other one. Hell yeah post a thread if you get them running...more project threads are always good.

Gnomad posted:Actually, that bike was registered as a 1962 BSA, using the engine serial number. The builder got a title from one of the title agencies, getting a 1962 title solves a lot of technical and paperwork issues. Getting it insured was interesting. "BSA, what kind of Harley is a BSA?" Interesting....but yeah, the older the bike the easier of a time you'll have, at least out here in CA.

This is why the "just needs a tune up and a carb clean" is bullshit. And it's amazing what abuse can be handed down, and an engine will still run...

8ender posted:Old bikes are awesome for this. I found out that my YDS3 will run just fine with one spark plug completely missing. Don't feel bad. I ran my 93 ZX6E without coolant for, oh, 10k miles. See, the problem is that when the guys who ship your new engine bash it against the wall, it has a tendency to bend the brass coolant rail across the front. If you don't notice this, everything seems fine, but when the bike gets hot, it'll slowly drip out coolant. I, of course, didn't notice, because it was only a drip every so often, it ended up on my exhaust, and I was running water with water wetter for track use, so it didn't smell funny. The temp gauge would go higher than my old engine, but the temp gauge never went into the red. I figured it was just an idiosyncrasy between engines.  Those 10k miles included some track time, and a trip to laguna motogp in 110 degree weather. The engine blew the day before a trackday, while I was doing a shakedown run at around 155mph. Sounded like I caught a rock in the fairings, but the engine didn't seize until I'd slowed to around 30mph.

8ender posted:It leaks when its off but only a small amount, then it stops. The vacuum petcock is new and works great. I suspect its leaking fuel from that one carb until the fuel level is below the top edge of the float bowl and then stopping. It doesn't leak at all on the centre stand, even with the petcock set to prime. Are the floats all set to the same height? Is it coming out of the overflow?

8ender posted:Yeah same height. Its coming out where the float bowl meets the carb. Any chance of a bent/warped float bowl? I've sometimes had luck ghetto repairing poo poo by cleaning things up well and then slathering some RTV on the outside to help it seal. Also, sometimes too much or too little torque on the float bowl bolts can cause it to not seal properly... Z3n fucked around with this message at 00:19 on Apr 7, 2010 |

Now, let's come out with this first: I don't have any experience with 2 stroke carburation besides playing with my friend's RD350 quite a bit. What I can say is that flatslides, when set up and tuned correctly, give you absolute control over what the carb is doing. It doesn't get any simpler than you simply directly lifting the slide yourself. Most modern flatslides have accelerator pumps which completely do away with the issue of them running lean when you slap the throttle. The throttle response is, bar none, the best I've ever had on any motorcycle. Custom tuned CBR600RR racebikes with built engines, brand new R6s with drive by wire, I have yet to ride a bike that responds the way a properly tuned flatslide does. You can whack the throttle, the bike wheelies and doesn't bog, you can roll on smoothly and progressively. They're fantastic. They give you excellent feedback and control over what's going on because you control exactly how they feed in the air and gas. Now, do they belong on every motorcycle? No. I'm sure there is a point where you could get the throttle control on a FI bike as good as a set of flatslides, there's other things to think about besides throttle response, but nothing I have ridden ever compares to a bike with a properly set up pair of flatslides. Many of them have been very good and gotten close, but none of them have ever got that dead on response feel. They also run flatslides on the 125 2 stroke racebikes, so I wouldn't be overly concerned about the size against the carb technology. It's a carb, it delivers fuel, when it's correctly configured it's going to work on any size engine. The only downside that I've found to running the flatslides is they can be a little to a lot more fuel hungry. Besides that, they're the preferred carbs for people who are looking for responsive throttles and more power. If you pair the appropriately sized carb with the bike, I can't see why you'd have any issues running a flatslide. All of this is just here as a counterpoint. Opinions are like assholes, blah blah blah, and I'm looking forward to seeing more pictures and videos of you building the bike up. I can't honestly say if I would choose to run a flatslide on that bike unless I had some form of baseline for it, because just like any other carb out there, if you gently caress up the setup it'll be miserable and you'll hate life or be spending a bunch of money on dyno time. On a 2 stroke where being lean is a Big Deal™, it may not be the best choice. Z3n fucked around with this message at 00:15 on Apr 27, 2010 |

ReelBigLizard posted:Thanks for the information, everyone. At least it's a bit more civilised than the Questions thread. There's a lever attached to the circular part of the carb that the throttle cables attach to...when you slap the throttle, it moves a diaphragm that creates vacuum and forces fuel out of the float bowl and sprays it directly into the intake. If you open it more slowly, the diaphragm never creates enough vacuum to pull the fuel through the passageway. quote:Properly set up and considered flatslides are clearly a performance advantage, which you could say is 'better'. It isn't everyone's idea of 'better' though. I want this bike to be a counterpoint to my KTM 690, which is like having your nerve endings wired into the throttle response. Riding it is to be constantly working the bike; with the BSA I want a bike to wrench and enjoy the scenery on*. You just need to find a girl who's...wired...the right way. Vibey single, ya know. And a well set up flatslide shouldn't be snatchy or harsh either...but I don't know if I have the most reasonable expectation of what "throttle response" should be like. I like that instant response on all of my bikes, regardless of their intended purpose, it's a throttle, it should respond when you twist it.

ReelBigLizard posted:And when I have money to buy one, and more importantly time to spend loving with it, I'll try a flatslide. But until then, the standard Amal carbs are the known quantity, the bantam/amal combo is so ubiquitous that most dealers can set them up near enough dead-on for you. Yeah, that's what I'd do, honestly. There's nothing I hate more than tuning carbs, the SV and the DRZ just have the advantage of having known setups so they're essentially plug and play. You should post a thread about your bike

It's a little low and they want to charge it for me. I'll take a look at the wiring while I wait for it be charged. Sounds like your battery might have an internal short, or you could have a break in the wiring harness. Can you jump it off of a car battery without the battery installed?

I'd get it running first and see where to go from there...the only big failure in those bikes is the stator, which requires some work to get out. And yes, someone made that a hardtail for some retarded reason. Luckily, you should just be able to bolt up a set of shocks and be good to go, those bikes handle poorly enough without putting a drat hardtail on it.

I'd be interested in a site for cheap bars too. Just replied to your PM, sorry man, but I hope you got it for 200$. If it's a runner for 300$, though, that's still fine, those engines are bulletproof with the exception of the stator issues.

AnnoyBot posted:I had drag bars on my XJ650 Seca for years, and I recently swapped on a set of clubmans. I definitely like the clubmans better, though if I ever really get the loving carbs sorted out such that it's fully usable I'll probably put superbike or daytona bars on. I've got the reverse problem...the amount of rake on a clubman bar causes instant pain. The nearly straight on of mildly bent dirt bike bars or drag bars is perfect for me.

You can get all kinds of weird behavior with a battery that's low or failing, that's why it's so important to test it and make sure it's good before you move on to anything else. The rattling that goes away when you pull in the clutch sounds like a worn clutch basket or bearing. Once you load it up it stops rattling. If your battery was dead after a long ride, chances are you have a problem with the charging system. Get the battery fully charged, and then tell us the voltage at the battery when you start it and rev it to 3k or 1/3rd of total RPM, whatever is higher.
