Yamaha timberwolf wont start unless push started

I have a yamaha timberwolf unk year. i think it is a 94. anyway it has electric start and reverse. it is a 250cc. i have tried to start this thing with the electric start button and nothing happens. if i jump the selinoid the engine turns over but doesnt run. i am sure the engine whips over. the starter gear is engaging. but it just turns and turns and turns. if i plain out push start this thing it will fire up. it has good compression because i have to pick up the *** end and drop it to start it, in 4th gear. if i give the 4 wheeler a little push while the elec start is whiping the motor it also fires up. as you can see i have a delima. please help me fix my baby.

15 years late..but buy a 30 dollar compression tester and find your valve time has slipped due to shorn key on sprocket. My son just diagnosed his with exactly same scenario.

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.

    If you push it starts.....cranks like a wiz..... Starter is canceling the ignition somehow. There is a starter relay. Is this like a car ignition switch ? Key does all?. If so, and it sounds like it, there is no current going to the coil when cranking. but there is current in run position. Yopu say you have check for fuse burn out? Well, that wouldn't be affected by dropping. My friend. It has to be a wire is off or your ignition switch or at the ignition switch..I think it is your ihnition switch because when you crank it is also supposed to provide current to the coil.by bridging over to the run position.. It has to be the switch, no doubt. Where are you located? I'm in CA

    you push the start/crank button and nothing happens. I would bet you yhe key switch is NOTproviding vurrent to the button. Jummping the selonoid and running tells you the problem is before theelonoid/relay. Power to key switch,then key on power to sraer button, then start button to selonoid. Ch.k power in that path button provides power at the post(small) yhat you are crossing to the battery cable. on the soelonoid. Key switch still my target. If you put juice to the key sideof the button and then push the button it will crank and start. Well, it should.

No electricity going to spark plugs on yamaha timberwolf!

It might be a faulty ignition coil or CDi unit. You will need to refer to the wiring diagram and do some careful checking with your trusty multimeter or get yourself some experienced help and advice.

Yamaha Timberwolf. How can I find model number to order parts

If you can tell me your vin - or your year I can tell you what model you have. But - if you go onto any parts site - such as cheapcycle.com or partsmonster - you name it - you won't need your 'model' # - just your year. You'd click - Yamaha OEM Parts, then ATV then Year - 1992 - 1998 was the Timberwolf - a lot of parts from the 99 - 04 Bear Tracker will work (just about only changed the plastics and carb in 99 - 04) same engine/transmission/rear end, etc. the brakes also went from drum to disc - but you'd click on the year - and then look - the timberwolf will be right there the 1992 - 1998 Yamaha Timberwolf 250 - I can't remember if they offered a timberwolf 350. If you can tell me the vin or year - like I said - I'll reply with your exact model # - but you can buy and order most parts just by model name and year 95 Timberwolf.

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.

CARBURATOR SIZE

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.
