1999 Yamaha Timberwolf 250 will not turn over. Took it to someone they said it was stator. Replaced stator and spark plug still wont turn. There's no noise anywhere.


Hi, Anonymous and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

Yamaha Timberwolf. How do I find model number to order parts?


I apologize - my answer to the previous question didn't really clarify your actual question - Your VIN can be found along the frame rail - left hand side - about a foot or so ahead of your left foot guard -

26028714-jbdqfs5232kzbw0rj532ox50-2-0.png

If it's still there - your model number is here:26028714-jbdqfs5232kzbw0rj532ox50-2-2.png

If you can read your VIN - and here's a tip to know you're getting the whole number and it's not rusted away a digit; your second digit should be a (Y) - if you write down your VIN, second digit is Y so you know the placement is right - the 10th digit is the year. And here are the breakdowns for that 10th Digit:

(For all Yamahas - not just the Timberwolf):
88 - J, 89 - K, 90 - L, 91 - M, 92 - N, 93 - P, 94 - R, 95 - S, 96 - T, 97 - V, 98 - W, 99 - X, 2000 - Y, 01 - 1, 02 - 2, 03 - 3

From 1992 - 1998 the Yamaha 250 4-stroke, shaft drive, trail bike was the Timberwolf.

From 1999 - 2004 the Yamaha 250 4-stroke, shaft drive, trail bike was the Bear Tracker.

*****SAME ENGINE, SAME TRANSMISSION, SAME REAR END, TIRE SIZE, PULL START - THINGS THEY DEFINITELY CHANGED IN 1999 WHEN THEY STARTED CALLING THEM THE BEAR TRACKER: - PLASTICS BECAME A LITTLE LONGER I BELIEVE; AND THE SEAT WITHOUT A DOUBT BECAME LONGER. THE CARB WENT TO A CONSTANT VACUUM - INSTEAD OF THE SLIDE CARB WHERE THE THROTTLE CABLE WENT THROUGH THE CAP LIKE THE TIMBERWOLF. HARD TO REMEMBER - BUT I THINK THE TIMING CHAIN TENSIONER BECAME UNADJUSTABLE - AND NOT MUCH ELSE CHANGED. IN 99 THEY EVEN KEPT THE BRAKING SYSTEM THE SAME. SOMETIME AROUND 2000, 01 OR SO THE BRAKE SYSTEM CHANGED FOR THE FRONT WHEN YAMAHA WENT TO DISC BRAKES. HOPE THIS HELPS. ANYTHING ELSE YOU NEED TO KNOW ABOUT YOUR TIMBERWOLF JUST LET ME KNOW - I'VE OWNED, REBUILT, BOUGHT, SOLD, TRADED A TON - I'VE CURRENTLY GOT A 99 BEAR TRACKER THAT IS THE MOST DEPENDABLE 250 4 STROKE I'VE EVER OWNED AND A 1996 YAMAHA WOLVERINE 350 4X4 - I'VE REBUILT THEM FROM THE BOTTOM TO THE TOP. THOSE BIKES ARE GOLDEN IF YOU TAKE CARE OF THEM AND DO A LITTLE ROUTINE MAINTENANCE. ALL THE BEST - JUSTIN MCCARTNEY

THE 99 I MENTIONED THAT I STILL HAVE:
26028714-jbdqfs5232kzbw0rj532ox50-2-5.jpg

A 98 I BOUGHT WITH THE ENGINE IN A MILK CRATE THAT I BOUGHT, REBUILT & SOLD:
26028714-jbdqfs5232kzbw0rj532ox50-2-9.png

A 2004 I BOUGHT, REBUILT AND SOLD:
26028714-jbdqfs5232kzbw0rj532ox50-2-14.jpg
All the best - let me know if you're ever in a jam with yours; not too much I haven't seen, fixed or had to deal with.

My 1994 Yamaha Timberwolf starts but won't idle properly. Sometimes when it quits it backfires. What could the problem be?

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 !

Won't idle steadily


Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)
