Question about 2003 Yamaha YZ 250

1 Answer

CARBURATOR SIZE I was given a Yamaha Timberwolf 2wd (unk year) with some major carb problems. Allegedly the carb was rebuilt but still has issues. I do not want to invest a ton of money and figured I could just buy an aftermarket carb and that would hopefully get this thing up and running. Do you guys have any idea what the OEM size would br for the bore and spigot mount. Can you also suggest a decent aftermarket product. Thanks

Get the VIN number for the bike and ask the local yamaha dealer. (the VIN number has a code for the year in it) what was originally on it when new. and what can fit on it from the aftermarket products.

Yamaha 650 v star tps,.. how do i find it on a 2004...then how do I test it to see if its the problem??


I would still think this is a carb issue. Most techs stink at properly rebuilding carbs because there are so many different kinds.

I however have spent 15 years honing my carb skills to perfection.

If the bike was purchased from a person at a higher altitude, main jet size might be incorrect. Or if it has modifications to the exhaust or intake - also main jet.

Contaminated or old fuel could also be a factor - have you drained the tank?

The TPS has to be set and checked with an olm meter. The TPS controls the CDI second timing curve which may have failed. I have seen this many times!

1982 Yamaha Seca Turbo (XJ650LJ) Had the carbs


Mine was stored for 20 years, I ended up replacing the seat and needles, cleaning them thoroughly and when I tried starting it, nothing!! No gas was going to the carbs, it turned out to be my gas pump, it was seized by the old gas remains 'varnish' so I had to clean it numerous times, soaked it in gas cleaner (short period at a time 15 minutes or so, being a very powerful cleaner, you cannot leave it for long without causing greater problems, thus I was able to get the pump going by boosting it with my car batterie, having more cranking amps directly to the pump, the pump was able to release itself from the old crusty varnish.

Is there any usuall problem with a yamaha fzr 600? Here it is. I'm about buy a 1996 yamaha fzr600. But my friend said it's a pretty old bike and it tends to give a lot of issues. Something with the...


I agree with your friend. Most shops will not work on a bike over 10 years old. Dealers no longer have parts in inventory is one reason. The problem with the carbs is that they are CV carbs. This is a type of carb that uses an air pressure actuated slide. The throttle cable is not connected to the slide at all. If the diaphragm gets a pin hole or bad seal, the slide won't raise. Diaphragms are $160 each, if you can find them. Your best bet for parts is Babbitt's. Please rate my answer, thanks.

Yamaha timberwolf wont start unless push started


You have a loose connection to the ignition system . When cranking make sure it is in neutral. and kill switch is in run position. The only thing dropping would sensibly affect is the fuel system or jarring a switch., but with the suspension you have there really is no jarring. So, I would ck the wiring. something is loose.

Yamaha timberwolf 4x4 carberator issues


Hi,

Firstly, if you are not a mechanical person you should never buy a vehicle that does not run.
However, here are some basic tests.
1. Connect a good battery.
2. Remove the spark plug.
3. Turn the motor using the starter motor or kick starter.
4. check for spark by inserting a new plug into the plug cap. (make sure the plug is grounded).

If the motor turns freely and there is spark, chances are good that the motor will run. This does not mean that the motor is in a good condition. Only with the motor running will you be able to know for sure.

You will now have to source a carb and fit it to the 4 wheeler.
Fitting the carb is not too difficult. Check that the intake manifold is not perished or torn, and remember to use the airfilter.

Enjoy the ride !
