Is there oil in the gearbox? Is it really dirty? Lack of oil and dirty oil could account for the clutch problem. If you have put synthetic lubricant in the gearbox that could also account for the clutch. Synthetics can swell the cork on the clutch plates. New fiber plates would be needed.

The shifting problem could be tied to the lack of oil or dirty oil but usually the problem is bent shift forks. If fresh oil doesn't fix the clutch the clutch will need to be inspected/repaired. If that doesn't also fix the shifting, ( and I don't think it will ), the engine will need to be torn down and the shift mechanism inspected. Forks will likely need to be replaced.

2011 Yamaha grizzly 700 special edition there is a plastic cover missing by left foot peg do you know what it is called looks like it covers oil dip stick area

These are often called plastic side covers or cowlings. Your Yamaha dealer should be able to give a quote on the price and then you can seek the part for much less elsewhere.

Yamaha grizzly gear engagement

From experience, its one of two things, bent or worn out shift forks or worn out engagement dogs on the gears themselves. A professional job. Does it fall out if you hold the gear shift up or down while driving? Take it to your local professional!!

Why does my Yamaha grizzly 700 engine brake fail going down hill

If you're in to low a gear, the clutch might be slipping under stress from high revs. You might need a new clutch or stronger springs. Try using a higher gear and use 50% braking.

Put enough grease to cover the rollers. Also add some to the actual tracks where the rollers glide on. The clutch should have a thin cover that is held on by three small screws. that is your "grease cap" If there is too much grease it'll end up there. Hope this helps. I own older grizzlies and that is what has worked for me.

I'm having trouble getting my 2011 Yamaha 450 Grizzly into neutral so I can start it. It goes into all the other ranges just fine, just the neutral is the problem.

that is a shift cam problem most likely. Pull the clutch cover and inspect the clutch shift quadrant and the clutch discs while you are at it.

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.
