Question about 1990 Yamaha TZR 250

2 Answers

I need the timing spec for a 1994 yamaha timberwolf 250

I'm rebuilding a four wheeler for my neighbor. his atv's starter clutch suffered catastrophic failure. the starter clutch cover was minimized and circulated thoughout the cases after the 3 bolts M8x1.25x15mm sheared. I have disassembled, cleaned and reassembled the cases and trans. I need to know what the stock timing setting is supposed to be. If you bare looking at the engine from the (shifter/ stater/ starter clutch) left side, on top of the head just above the cam timing adjustment cover '' 4BD'' is cast on the top of the head. does this mean ''4''deg. ''B''efore top ''D''ead center?

No dont worry about that # what type of machine is it? what your gonna need to do is find the mark on the fly wheel some have a single mark and some have two if you have the cover off put it on there should be 2 access holes take the covers (small and larger probally flat head allen key) turn the engine counter clockwise till you line the second mark you see in that little window if it has two there should be a mark to line it up with, that is top dead center now there will be marks on the cam sprocket thatneed to get lined up also thats where i need to know what kind of machine it is but somehave an arrow some have two lines that get lined up with the gasket surface. if you post it i can help you finish

1995 Timberwolf. When I try to start it, all I get is a click and it will not go into gear. What's wrong?


Hi, Brooke it should be noted that in order to "PROPERLY" diagnosis any electric starter issue it is "IMPERATIVE" that you begin with a fully charged battery 12.5 volts or better and be able to pass a proper load test, and the usual suspects are:
1. Battery terminals have loose or corroded connections.
2. Battery cables faulty due corroded or broken internal wiring at the cable connector especially the "NEGATIVE" cable which needs to be checked at "BOTH" ends.
3. Battery voltage, 12.5 volts or better,to the main circuit breaker to the ignition switch to the security/ignition fuse to the TSM/TSSM module to the engine stop/run switch to the starter button to the starter relay to the green wire that connects to the starter solenoid has dropped more than 1/2 volt.
4. With a voltmeter connected to the battery, the ignition switch in the on position, the kill switch in the run position, the starter button depressed, starter engagement should not bring voltage below 8-9 volts.
If a lower voltage is produced a proper battery load test should be performed with a load tester to validate battery integrity or battery replacement.
5. Faulty starter relay, check continuity.
6. Faulty starter solenoid, check contact plate and shoes for excessive electrical erosion/etching, refurbish as necessary or invert contact plate and use the virgin backside. Check contact shoes for being loose. Replace solenoid if the negative function is still a final outcome.
7. Faulty starter, bench test starter with a 12-volt battery if negative function check, decontaminate and undercut armature commutator segments as necessary, check segments with an ohm-meter probe each one and the segment next to it for shorts. Have the armature tested with a growler and field coils, and brush plate with an ohm-meter for opens, shorts or grounds. Replace brushes if less than .438" It is generally cheaper to overhaul/refurbish a starter motor than buy a new one.

How to fix the yamaha krypton starter not engaging the engine


Hi, Anonymous the starter drive/Bendix/clutch is a mechanical gear driven component that engages the clutch pack ring gear to turn over the engine. It has an internal mechanism that allows the gear to turn in one direction and once the engine starts allows the drive gear to free spin. If gear free spins in both directions then the drive gear has failed, it is not serviceable and needs to be replaced.

How to replace the rear brakes on a 1992 Yamaha Timberwolf 250cc 2X2 four wheeler


Go to the site below where you can see a parts diagram for your specific ATV. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part and/or the notation "Not Available" is in the description, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

It looks like all you need to do is remove the right rear wheel to get access to the brake.

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)
