Water hammer noise coming from refrigerator

Eight_angels, yes such hammer noise is common and it is easy to fix! That hammer noise will eventually damage your plumbing unless fixed, I use an easy to install Sioux Chief 660-GTR1 surge suppressor with an air filled surge absorber to fix the problem, usually costing around $12.

Worn or broken piston rings or warn valve guides. A compression test will let you know which one.

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.

My 04 raptor 660 will not start i checked the spark plug to see if it was firing and it is and its getting fuel also what should i do wil only spin over

The three required ingredients for combustion are: fuel, compression, and a spark (at the right time). So, if it's got fuel and spark, I would check the compression. With the throttle held wide open, you should see at least 140 psi of compression. Anything less than that - and it isn't going anywhere (under its own power).
If the compression is low, check and adjust the valve tappet clearance. Insufficient tappet clearance is the most common cause of low compression in 4-cycle engines.
If the compression is okay, and it still won't run, then check for plugged carburetor jets. Especially if the bike has ever sat for more than a few months. Gasoline, when it evaporates, leaves a gooey mess behind.
