Question about Yamaha 2005 Grizzly 660 Auto 4x4

My 05 Yamaha Grizzly 660 will not start. In my limited troublshooting practice I looked at FUEL, FIRE and AIR. Here is the fault, the engine will not start. I checked wires/fuses, plugs, fuel lines and air flow. The starter is working properly, it will crank over the engine. I have replaced the spark plug, topped off the gas, removed the spark plug to ensure that there is a spark by watching for a spark when I pressed the starter button, reinserted the spark plug and tried again. Next I thought that it could be a sticky carburator, I took the air filter off and sprayed carb cleaner into the carburator, it cranked over and ran for about 1 sec then died. I did notice that when I took the spark plug off it was dry. I then thought that the carburator wasn't getting gas. I checked the shutoff/run/reserve switch to ensure that it was operating properly by pulling off the fuel line and ensuring a proper flow. Once I noticed a good flow I reinserted the tube onto the carburator. After all of that the darn thing still will not start. Do have any idea's? Thanks for the time and support.

SOURCE: Strange thigs about YAMAHA TW 125

Hi
I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.
Cheers

Take the carburetor apart again, remove the main and idle jets and idle mix screw, plus the float and needle valve. The main jet holds an 'emulsion tube' in--look inside where the slide valve moves, you should see a short brass tube projecting out of the bottom. Carefully push down on that tube with a plastic rod or wooden dowel, it should drop out the hole where the main jet was. Chances are that the tube is dirty and needs to be cleaned--look carefully at the series of small holes drilled into the sides of the tube. These small holes deliver air which is mixed into the fuel passed through the main jet. That air comes from a small hole just inside the intake side of the carburetor. The long needle that sticks out of the slide bottom controls low to mid-range speed fuel-mixture. Check that the 'C' clip on the top end of the needle is in the center groove and that the retainer spring is pressed down the 'C' clip. Now soak the whole carburetor with spray cleaner, then blow out all passages with compressed air. Don't soak the rubber-tipped needle valve from under the float. On reassembly, set the idle mix screw 1-1/2 to 2 turns CCW from CW stop. Adjust for best idle after you get it running and warmed up. I hope this long winded explanation helps!

SOURCE: 2005 grizzly 660 rear drive shafts pop out of the gear box a lot

There should be a circlips at the end of the driveshaft.
That circlips holds the shaft IN the differential parts.

If you have still warranty, let it repair by a dealer. The circlips is maybe INSIDE the differential casing and can thus destroy a lot of parts!

well here goes your problem probably in the float bowl area water sediment blocked low speed jets if you do not want to do a complete tearmore down just clean the jets and float bowl.
Use a carb cleaner soak the jets make sure you can see through them the small low speed jets specially.
if you have access to air blow the jets clean.
spray any passage ways with carb cleaner reassemble good luck.

Backfires when you try to rev up engine,


check fuel flow and check spark at spark plugs

According to an "ATV Rider" 2009 article, "When the Grizzly was introduced in 1998 as a 600cc machine, the top was blown right off the displacement wars of the time."
It was replaced in 2002 with Yamaha Grizzly 660, an even bigger engine derived from the well-established all-terrain vehicle (ATV) Yamaha Raptor 660R.
Grizzly's 660 cubic centimeter (cc), four-stroke, liquid-cooled single overhead camshaft, five-valve engine performs well in open country, but sometimes it causes serious problems for owners.
Before you call a Grizzly dealer, however, trying a few tricks in your garage can save you a lot of time and money.

Check the fuel level.
Locate the fuel meter indicator on top of the multifunction display.
If it does not work properly, open the fuel tank, and push the Yamaha 660 Grizzly side to side.
Ensure the fuel is not contaminated by water or rust.
If you have not driven your Grizzly 660 for a long time, drain the tank completely, and fill it with a fuel tank cleaner.

Check fuel hoses for cracks or leakage.
The hoses should be soft and simple to bend.
Replace those that show any sign of wear.

Check the compression.
Screw a compression tester into the spark plug hole, and press the electric starter button.
If no compression exists, contact a Yamaha dealer.
Wipe wet or dirty electrodes with a dry cloth.
The spark plug gap should be checked regularly

Correct the spark plug gap.
Measure the gap with a wire thickness gauge.
If necessary, adjust it to 0.8mm using a screwdriver or replace the spark plug.
Use only a Yamaha-specified spark plug.

Check the Yamaha 660 Grizzly's battery.
Operate its electric starter.
If the Grizzly starts quickly, then its battery is in good condition.
If the engine turns slowly, check the battery lead connections, and you may need to change the battery.
If the engine still does not eventually start, your Grizzly is beyond home repair.

Sounds like you have a stuck float needle in the carbs (2). Usually after a few days with gas in the carb they will free up, you could 'knock' on the carbs with the plastic end of a screwdriver to help free them up. If not, turn off fuel, drain the carbs and fill them with carb cleaner for 24 hours. Redrain, attach fuel lines and turn the gas back on. If still no start it's time for a rebuild...
