A shop manual (particularly one with colour photos) will offer some spark plug diagrams / photos, to compare against your plugs, but they're not particularly useful. As you said, claims are contradictory. The problem is, that a symptom of too lean/too rich is that it doesn't run as well as it should. That's both ways. So a too-lean symptom for one person is ...

The 2012 XJ6 is fuel injected, so an aftermarket exhaust (Arrows, Leo Vince, Scorpion, Two Brothers, Akrapovic etc) would be easily procured. You may even get good deals on used slip-on exhausts, and you could then re-pack the glass wool (other as applicable) if required. In order to keep the cost down, you could opt for a slip-on exhaust (muffler) instead ...

Breaking in the engine correctly will greatly affect the longevity and performance of the bike, plus you have warranty regards to worry about as well. I found this from a Yamaha forum and seems along the lines of what I understood to be right: According to Yamaha, you are to keep the engine below 5900 rpm for the first 600 miles and vary the rpm. Do not ...

The issue could be a vacuum forming in the fuel tank (check vents), looking at the yamaha site, it doesn't look like you have any active cooling (fan/radiator) so unlikely to be that. There may also be an air-hose leaking somewhere or possibly a vacuum leak from the intake manifold.

Check out the Yamaha web site for the models you are interested in. They should list technical specifications for each model. If you are concerned about performance differences focus on peak horsepower and peak torque at a specific rpm along with top speed.

To add on to Mikes answer: Next you'll probably find that the carb is full of varnish. (a thick sludge left behind when gasoline sits in a puddle for a long time). You'll probably end up having to disassemble and clean it out, you may need to by a carburetor rebuild kit. (probably) Next, there's a good chance that the rodents have damaged the wiring. ...

Remove the spark plug. Squirt some oil into the cylinder,you can use regular motor oil but Liquid Wrench or equivilent would be better. Let it soak overnight.With the bike in neutral see if the motor will spin over using the kickstarter. If it won't turnover the motor is seized. At this point it is not worth repairing but could be a valuble learning tool. ...

A quick Google search resulted in this. I couldn't find the legend for it but I guess it should be fairly straightforward. It could be bad wiring, bring out the multi-meter! EDIT Here's a link to the COMPLETE SERVICE MANUAL . It's in German, so you may need to use a translation service .

Yes, you can relatively easily determine if your fuel filter is clogged. The XJ600 has a vacuum operated fuel pump below the downdraft carb bank. This is what it looks like. The stock fuel filter is an inline filter and this is what it looks like. As I'm sure you have noticed, the filter is a bit opaque and you can see if it is clogged. It's very easy ...

By removing the baffles you have reduced the amount of restriction and backpressure. This has the effect of making the engine run lean. If you get the carbs tuned so that it's running properly, it should run as well as it did before you performed the baffle-ectamy. With a free-er flowing exhaust it may even run better. But that's only if the original ...

I spoke to someone who has Grizzlys for similar work here, he suggested the following necessities and spare parts: Basic repair kit Carburetor Spark plugs Air filters Oil filters Brake/throttle cables Fuses CDI unit Starter coil Electrical relay

Overview There are a few items that would be considered essential regarding maintenance and consumable parts. Parts on quads that are considered consumable include the standard items such as break pads but also items such as brake levers. Since the vehicle may tip over, breaking a lever. Kit Items Tire repair kit. This would include a good set of ...

Modern motors (and other aggregates) produced by reputable manufacturers (Yamaha be one of them) for established markets (Western Europe, Australia, North America etc.) are engineered with low tolerances, thus should have little variances in operation. In emerging markets engines could be (or could have been not long ago) older, and poorer manufacturing ...

I highly recommend that you find yourself a shop manual for the bike. These are available in hard copy version, and sometimes in PDF format as well. It will make it clear how to perform various operations, and make it less likely that you will do it wrong. I highly recommend that you do not mess with any of the gears. Transmissions run at very tight ...

Took it to a mechanic and he found the problem with a test ride. It is a side effect of the lowering links being installed too low. I am just too dang short for the bike. After I sit on the bike the chain hits the chain roller (which was torn all up) and at a certain vibration you hear it clinking away. I'm re-installing the factor links and hope I don't ...

Agree with @mikes ... your issue is lack of fuel. That "hollow/rattling" noise is pre-ignition/knocking caused by a lean fuel condition. If you keep trying to run your scooter like this, you will blow the piston out of it (if you haven't caused damage already). You'll probably need to rejet the carb and get more fuel into the system. The reason why it ...

Answer: the plastic screws are really delicate and they do not turn with enough accuracy to really unlock the panel. The only way I have found is to insert a lever and pull harder, and the panel comes out without breaking anything.

I had to look it up as I've never heard of an AG200 but I know what TW125/200 is If your looking under the right side engine cover, lock the clutch and primary drive gear with a penny between teeth, it's easier than trying to use the special tool you need but don't have Make sure you don't use the oil pump drive gear as it is too small for the load and ...

The battery is dead. You are hearing the starter solenoid clicking over. Does your bike not have a kick-starter? It's only a 250, it should, right? I don't know much about new bikes at all. If you do happen to flood the engine again, just go full choke, and spin the engine over a few times. That should help unflood them, if that doesn't work, go inside ...

The battery was dead. I removed it, put it on the tender, and she was able to turn after a charge. Just goes to show its a very large amount of juice needed to get the engine started. Don't undermine the importance of tending.

There's usually two methods people discuss. The 1st method is the one Paulster2 described, which is by the manufacturers suggestion in the manual. The 2nd is a more controversial method of running it hard. Here's a snippet from [MotoMan][1]: The Short Answer: Run it Hard ! Why ?? Nowadays, the piston ring seal is really what the break in ...

If the only thing that changed between then (ran fine) and now (won't fire) is carburetors / fuel, and if it now won't fire on ether, then either your ignition timing is suddenly far out of whack for totally coincidental reasons or else your spark plugs are now too wet (with fuel) to fire from flooding. Pull out the plugs, let them air out, let the cylinders ...

My guess is you flooded it (possibly stuck needle after the first rebuild). And by putting gas and starting fluid directly in the cylinders, you have privacy made it worse and washed out the rings on the piston and have essentially lost compression. Typically, I would turn off the gas tank petcock so that no gas is getting to the carbs, and crank it for a ...

Carbon Fouling is caused by incomplete combustion. The usual cause of this is an over-rich mixture, but it sounds like you've checked most of the elements that could cause that. What condition is the ignition system in? Distributor, HT leads etc? I assume you've checked the mixture when you changed the jets, but what about the choke (if she has one)? What ...

You might be able to find something used on eBay that will fit, but who knows how much wear it has had? If you plan to keep the bike a while I would shell out for new, high-quality shocks. Here's a link to some that say they work. They should come with the bushings needed. Yes, the price is pretty steep, but shock technology has advanced a lot in the ...

Have you tried contacting a large bearing distributor. Here in Australia I've used CBC Bearings in the past to obtain transmission bearings.
