Stopping a naturally aspirated engine will cool it down, regardless of the fan running and etc. The idea behind "turbo timers" on turbocharged cars is not at all engine cooling related, rather it is to allow the delicate and extremely hot turbocharger components to cool down via keeping the oil feed circulating through it for additional 15-30 seconds or a ...

The DT 230 Carburetor will fit on some DT200's The 1999 model of your bike uses the Mikuni TM30x1 Flat Slide Carburetor Older models use a different carburetor model. The slide is round. Here is an image of the flat slide carburetor. Here is an image of the round slide carburetor Both of these carburetors are readily available on ebay and Google ...

High Spot If I were to guess, you have a 'high spot' in your chain. Cause High spots have occur for a number of a reasons Ongoing poor care Low quality chain 'Clutch Dumping' which causes stretching of the chain. Water penetration of a few rollers leading to rust and inconsistent where on those rollers Remedy For now, adjust your chain to the ...

More than likely, you have an air leak If you haven't cleaned out and rebuilt a bunch of 4 carburetor banks in your life there is a good chance you have accidentally created an air leak in the system. Unmetered air will create the symptoms you describe. The giveaway on most lean conditions is the falling idle. It idles high and is getting enough fuel but ...

In the image below notice that there are no rocker arms or push rods. The cam acts directly on the shim and bucket which acts on the valve stem. You adjust the valves by changing out different shims to get the appropriate valve clearence. In this image, the shim is over the bucket. This is what your Yamaha has. You have an Over the Bucket Shim to adjust ...

There is no need to reprogram the ECU This is for a couple of reasons: The engine barely feels a difference Contrary to what the name implies, a "free-flowing" intake impacts the pressure at the valve inlet and not the volume of fresh inlet air per cycle. Here are the numbers to back it up: K&N provide detailed test data for the Yamaha R15, which ...

Most Kick Starters Have a Relative Position They Need To Be In What I mean by this is, you can get your kickstarter into the system and mount it up bet if you do not put the shaft in at the correct degree it won't operate properly. Think of cam timing. Perhaps a poor analogy but.... Look at this parts diagram On shaft 9 and gear 11 you need to have them ...

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.

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 ...

The exact answer to this is - It Depends... The reason for this is that your existing ECU, whether it be on a bike or in a car, has a range of inputs and a range out outputs, and a mapping between them. As long as your inputs are within the ranges expected, it may well be able to cope with the changed architecture, however there are two common problems: ...

I don't know for sure, but would bet your best option is the last one. I know straightening tubes of any sort is a very hard option. There should be an Allen head bolt which is clamping to the forks. You don't want to take the fork loose if you can help it, as getting alignment back right could be a huge pain in the butt for the uninitiated. If replacement ...

According to this User Manual on Page 53 (section 6-3) a Valve Clearance check should be carried out every 26,600 miles (42,000km). It also highlights any other maintenance that should be done and at what intervals. I think checking is relatively simple (assuming you are handy with a toolkit. I found a site that gives this method of checking your valve ...

There are a few ways to resolve this dent issue. Method 1 glue these plastic ding tabs to the gas tank. You can find them by googling "plastic ding tab" You will use a hot glue gun and hot glue them to your gas tank. Use a dent puller slide hammer. The tip should screw into the plastic ding pullers. Pull the weight of the slide hammer to the bottom ...

Exhausts can be difficult to remove. In many cases constant heating/cooling has burned off any coatings and the bare metal has corroded or rusted the nuts and studs together. If the exhaust has cylinder head studs with exposed nuts you can try several things. Start by soaking them with a penetrant oil. Only do this when the exhaust is cool enough to ...

I would suspect one of two things. Your main fuse is blown. This would disable your entire electrical system and prevent the bike from lighting up or starting. Your ignition switch has failed. If your ignition switch where you turn your key has failed your electrical system will be dark. If you have a multimeter you can unplug your ignition switch from ...

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.

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 ...

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 ...

If I am not mistaken the 2001 Yamaha Diversion has a clutch cable and does not have a hydraulic self adjusting clutch mechanism. This was my son's first motorcycle and we experienced similar issues with his. I will say that this model is bullet proof. Especially the 8 valve air cooled version which you have. Throw Out Bearing If your throw out bearing ...

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. ...

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 ...

Twisting the throttle opens the butterfly valve in the carburetor which allows it to suck in more air. With the increased air flow, the carb should also suck in more fuel. So, if enough fuel isn't supplied the engine can't handle the extra air. I don't know enough about your bike to offer a solution, but this is one possible cause.

If this is a carburated engine (not fuel injection) then it's likely that one or more of your carburettor jets is blocked or the diaphragm has a hole in it. Find a service manual for this motorcycle (there's probably a PDF of it somewhere on the internet) and follow the instructions for taking the top off the carb, you will need screwdrivers, small spanners ...

A bit of inspiration can be had from either the Yamaha or Kawasaki side by sides. If you have the time and inclination, go to your neighborhood Yamaha or Kawie dealership (they might be the same one), and speak to someone in the service department. In all reality, your coolant system needs to maintain a certain pressure, a pressure tester can be used. ...

The bearing you are looking for are still available in the United States. Do a google search for "1983 Yamaha OEM parts" You will see various Yamaha websites. Goto one and chase your bike with the make/model/year and this will be the result, the ability to purchase the bearings. All of the transmission bearings for the bike are still available for ...

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 ...

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 ...

If you synchronize and clean the carburetors the bike will not have the same power that it did before you removed the baffles from the exhaust system. The baffles created back pressure in your exhaust system that restricted the flow of the exhaust gasses. When you removed the baffles it allowed the engine to 'breath' easier due to the lack of restriction. ...
