If you have any issue feel free to reach out & I'll do the best I can to help you.
Just found your channel, great video for sure. What really catches my attention is the time you spent helping people with multiple problems in the comment section. Thank you for this video and sharing info with all of us.
I appreciate the kind words. That's the whole reason behind you RUclips channel.
Excellent Wrk there Master Mechanic 🌎
My very close buddy passed away and I was able to buy his grizzly 660. it to has sat up for at lease 6 years. another friend had this grizzly for two hunting seasons and then sold it to last owner. hardly no time on it. they were old guys so yes too very good care. but I probably have to do the things you have done. thanks
Very good! Thank you...
Thanks for the video, just got a grizzly 660 2005 and was looking for videos like this. Never really worked on 4 wheelers
The biggest pain in the but it just getting all the plastics off to access anything. I have another in the shop right now that has been sitting for years due to what the customer thinks is a bad head gasket. The video should be out in the next few weeks
@@limitlesspowersportsservic3394 oh cool, I’ll be interested to see it.
The grizzly i just bought has a flashing fuel light even when full. I haven’t checked to see if it’s actually plugged in, but do you think it could just be a bad fuel sender?
Thanks. Little far from Kentucky. Thanks
Lol yeah unfortunately. But hey sometimes it's totally worth the trip lol
That was extremely similar to the cfmoto 500 2012 i worked on built wise. They are quite easy to work on honestly, took me like 4 hours to remove the carburetor, clean it completely and assemble it again. It was my first time working on it too.
One thing i couldn't fix was the choke pulling back automatically, had to hold it down everytime manually. It worked but kind of annoying.
Yeah some times the spring on the coke cable is a little to strong & will close it self back. Cfmoto & a lot of your other after market builders cloned the Yamaha, Honda, Can am stuff.
Thank you for your videos on the 660!
Any chance you have one on spark plug location?
From what I can recall it is in the front middle of the cylinder head
This is the video that caught my eye and made me reach out. Please like and subscribe your videos have been really helpful. Thanks for all the content.
Thank you for the kind word. Glad to help.
Hell clean the carb put a new sparkplug in it an run it. Change the oil an run it til it breaks. These bikes are great an tough
I don't disagree with you at all these things run forever
I’m doing an 03 right now.
I just got a 2006 grizzly 660 for free that needs to ground to be rewired and full maintenance but came with new tires.
do you know how the rear wheel bearings go in and could you do a video on it? thank you!
I currently don't have one in the shop that needs rear wheel bearings. But you will need to press them in & out. It's so much easier with a press.
Hello Aaron. I have the same year grizzly as is shown in the video. I had a clicking noise in the front right side of machine. Saw the boot and come off. All the grease was gone out of the cv joint. So I disassembled the cv joint and axle shaft assembly. I found out a few things the hard way when I pulled the shaft off the snap ring fell off behavior the bearing toward the diff. I finally figured out that a C ring was holding the bearing assembly in the housing. I was able to get the housing out of the diff by gently prying on it. The question I have is that bearing and the bearing in the cv joint the same ??? I watched another video where it showed how to get the bearing out of the CV joint in a car so I tried it on my 4 wheeler and it worked. I could have probably just replaced the bearing if they are the same size. In the disassembly process the ripped the upper ball joint boot come to find the ball joint is welded to the A frame. So I have to replace the whole A frame for the upper ball joint. Not to mention I messed up the threads on the tie rod and upper ball joint. Where do you recommend buying parts for this machine and would you strictly replace with OEM Thanks Aaron. Sorry it’s so long just like to pass info on so other people can be informed
Well I would just replace the whole cv axle. It's a lot easier & less time consuming. I'm not sure about the bearing sizes tho. I pretty much stopped replacing the cv axle boot if there is clicking & popping unless my customer really insisted on it. Sucks to hear about the ball joint that someone welded on. I honestly have has pretty good luck with some aftermarket cv axles. But I do always try to recommend staying with OEM unless I'm asked not to due to cost
It wasn’t welded on. I am the original owner. Certain years they welded the upper ball joint. I did find the A arm from sports nation Used of course so we shall see. I do have a complete axle coming from moose 🫎 Thanks for your video. Any ideas where I can find a service manual for that machine ?
Well glad yoy found the parts. I use powersportsnation.com a lot. You can find a pdf version of the service manual if you just Google it.
Do you plan on doing a wheel bearing replacement video on the 2002 Yahama grizzly. This model has a spacer between the bearings ?
I currently don't gave one here at shop with that need at the moment. But yes this modle does have the Spacer in-between the bearings.
Videos are awesome! I’ve got my 2007 660 grizzly started, but it sputters and spits when I try to throttle up from idle. Even sounds like backfiring. I ordered a replacement carb off amazon and it does the same thing. Thoughts?
I would start simple. I would drain the fuel fisrt & check it for water, thenI would replace the spark plug. Also check the charging system to make sure your battery getting the proper voltage. The ATV runs off the 12volts from the battery.
@@limitlesspowersportsservic3394 it ended up being the fuel filter. I changed it once but then I pulled the tank and the filter on the petcock was torn plus there was some water in the tank.
I will never go aftermarket on a ATV ever again. IO went thru that garbage with Honda Forman and 13 cade kept flashing. I bought a ATV from a customer that would have costed him more that what the 2003 yamaha would have costed him brand new. He neglected to service the coolant system and had to replace everything. Now I'm working thru the starter clutch, although the one wat clutch is working fine, I still get the slight noise when hitting the start button.
Yeah after market part are really a pain in the butt thats for sure.I get a lot of stuff that has been used & abused then they would like to have it back to brand new untilvyou tell them the price lol
I just bought a grizzly appears to be a 2012 700. It ram fine when I got it for a few hrs then we added gas and after a few uses it started back firing and bogs down after a few minutes in use and turns off. It’ll turn back on fine and quick but once you give it gas it sounds like it chokes and turns off. Could it be the carburetor Maybe the gas we used was bad?
Sounds like you added some bad gas to it. I would start there.
Great video! I’ve got a 2007 grizzly 660 that I’m going through. I’ve run across a vacuum line that isn’t connected to anything. It is actually a t-adapter with 3 lines but none connected. I’ve got the manual, but no vacuum illustrations
Can someone help me?
I don't believe thay there are any vacuum lines on the grizzly. Most of those would be over flow lines & atmospheric vent line.
1st thank you for the reply. Ok, understand, but all ends are open. None of the 3 are connected to anything? It is tie wrapped with the main harness on the left side under the tank. Any ideas on what it should be connected to?
I noticed you giving her choke.
My machine does the same thing,
I'm wondering if it's NORMAL for this type of machine.
She starts with choke off, but it will dei on me sometimes,
But when I give her choke, the idle sounds fine, never dei.
So evertime I ride,
I will give her gas a bit and choke off.
I am not sure it that is normal or if I have a problem with my carb or any idle adjustment..the
The problem is non serviceable carb.
Good tutorial, I learned a lot.
Well appreciated
Yeah a lot of times you have to choke them a little bit when you first start them & let them warm up a little bit. Then you should be able to turn the choke off & it should Idle with out any problems. If you're using the choke while you're riding it then it's most likely a clogged pilot jet. When you say non serviceable carb are you referring to the float bowl screws being flat & noway to take them out? If so you can cut a small slot in them & use a flat head screwdriver to take them out & replace the with the proper thread pitch & length philip head screw.
@limitlesspowersportsservic3394
No choke when running. I always pull it off.
But when it idle even its warm-up and reach the temp level when I shut the choke, it will dei on me.
Mine is CFmoto 500, same carburator believe.
I have worked on the Cfmoto 500 before. You that will still he a issue with the pilot jet. Have you tried to turn the idle up a little bit? But it sounds like a pilot jet issue. That is what controls idle up to 1/4 throttle. You also be a pilot mixture screw issue also.
@limitlesspowersportsservic3394 I will look it all you mentioned.
Thaks
Just bought a 02. 3800 miles Plowed first time today. Noticed it kind of sticks when changing gears. Especially going in L. Then a few times it acted up going in R and made a grinding time noise for a bit and then went away. Any ideas or tips ? It’s supposed been maintained real well. The guy I bought it told me about sometime needs to rock it into L. But I can see it seems like a problem
Hey Mick. Sorry for the delayed responce. Jus saw this comment. It sounds like you might have a clutch issue. Take the cvt cover off & check the clutches out. The primary clutch might need to be cleaned & re greased. Sounds like the belt has tention on it causing the secondary clutch to turn making it hard ro shift into gear & making it grind. Also check the Idle. if its to high it can cause the same issue.
@@limitlesspowersportsservic3394 oh ok. Thanks for the info. Just finally got around and a chance to change the oil Seems like it’s shifting a little better but it’s still there. Does clean oil help with shifting at all ? Thanks for the info and I’ll check that out now as soon as I can.
Lower the idle
@@anthonyk6265 good idea. He did tell me he adjusted that to his liking and maybe that is the problem. Thanks !
Just went to fire up my '06 and could smell gas immediately. It runs great but lLooks like I'm changing the fuel petcock AGAIN! Gas leaks everywhere when the fuel is turned on. I can't remember where I got the last one. Any recommendations for a decent replacement? I didn't see any parts used or parts links in the comments. Thx.
Are you sure it's leaking from the petcock &are is the carburetor overflowing because if a back fuel needle? You can go to allballsracing.com & get the part & for a rebuild kit but put that part # into Amazon & the same product from allballs will come up but it's cheaper & fast shipping from Amazon.
@@limitlesspowersportsservic3394 I'll take your advice & double check everything. But I'm pretty sure it's the petcock again - super chintzy setup from what I remember when taking the last one apart. It may even stop leaking when the weather warms up and the material becomes flexible again. Thanks for the reply.
I have an 06 660 grizzly and have an issue with the starter relay burning up without tripping the fuses what do you think could be causing that. I had a new starter voltage regulator and starter relay module put on the last shop visit and the problem continues. Thanks you for any info available.
It's the starter relay & not the starter solenoid burning up? Hmmmm the relay wiring could have a short to ground somewhere after the fuse. I believe that really runs off of the main fuse with should be a 30amp fuse. The only time the relay should be completing the circuit is when you're pushing the start switch which energize the relay & let's power pass through to the starter solenoid.
I would also do a parasitic draw test to see if you have a draw on the battery with the key off.
I have the exact same quad. My battery won’t hold a charge, I do have a winch hooked up to it, I also got a brand new winch to throw on it because the one that came with it is going bad. I thought it was the stator on the generator going bad but I’m thinking the winch is bad, you have any tips?
check your battery for a power draw & then you may need a new rectifier. check your battery voltage at idle. It should about 13.5at minimum & no higher than 14.7 at 5000rpms.
@@limitlesspowersportsservic3394 I know atv’s when they sit have a natural draw of current to keep the brain going when it’s off. How long would it take for that to kill your battery just sitting over time.
That really depends on how new the battery is, what type of weather the battery is in & if the battery was properly charged when it was first being serviced for use. But if there is no other draw on the battery besides the dash & other milli volt draw the can last for 6 to 7 months.
What battery do u recommend for grizzly 660
I always recommend the OEM battery, but striker battery makes a pretty good one that has a 2 yr warranty.
Sorry I do have the same quad grizzly 660
What is the LLC . Is that for antifreeze
LLC?
Where do I find the spark plug
It's in the front middle of the cylinder head.
Do you have a list of the stuff it needs? I just bought my godfathers who passed and i want to change all fluids, battery, air filter and spark plugs. Do you have a list of everything for basic maintenance?
I can definitely look up all the part & for you. But I won't be able to do that till Monday. I'm out in the road with the race I work with.
I would also love to know which Carb you purchased. I will be doing this for my 08’ 660!
@Limitless Powersports service & repair awesome! You can email it or edit description couldnt you?
Here is a link for an 2008 aftermarket one on amazon.

The part # for the one I used in this video is a little bit different.
Hey John. I just posted some links in the description of what I used in this video. You can use you own choice of oil as long as its formulated for a atv wet clutch 10w-40 2.11quarts. Also the diff fluids is a 80w gear oil. Coolant is just your basic 50/50 premix from your auto parts store. The oil filter is a K&N 303. Hope this helps.

Here are the link for the carb & pet cock

@@limitlesspowersportsservic3394 when u get a carb off of Amazon or any other seller. Do you take it apart first and check it out and find tune it
@@limitlesspowersportsservic3394 have you had good success with those carbs
Oh yeah I definitely take them apart & check them. I have found the jet sizes way way to small before & I have had the float bowl full of some type of silicone grease. I have had more success that not. But I always prefer O.E.M. over aftermarket stuff. But sometimes the budget doest quit fit that want lol.
I finished same project on my 2002. The Chinese carb will last 2 weeks. It's junk. Will start to backfire and the Choke will not work properly. I ordered the mikuni directly from Japan I think I got the last one off the shelf. Unfortunately you fast forward thru everything that anyone that watches these videos for. Soak the old carb in pinesol for 24 hours and buy the correct Yamaha part rebuild the original carb. Also don't by the cheap ass fuel cock. It will leak thru in a few weeks and will cause the carb to gum up again. I'm the original owner of my 660. And a weekend mechanic by necessity.
Hey Tommy Taps. Yeah Im not a fan of the Chinese parts myself. I almost always by O.E.M. unless my customer tells me different like on this job. Any time I us aftermarket carb I alway take them apart & check all the jets & gaskets. I have gotten them where the jets were not the correct size , float bowl full of grease, missing 0-rings, gaskets, fuel needle ect... The pet cocks really suck because of the cheap ass rubber they use in them. Gas pretty much turns them into mush. Sorry about fast forwarding past the things you say people watch this for. Please let me know what that exactly is so I can make the proper adjustments in the future. Im always open for some constructive criticism so I can make the videos better for my viewers. Again thank you for the feed back & please let me know what you think will make it better for future viewers.
Have you ever run across an ATV that has been sitting that's not repairable
Hey David. Everything is repairable if parts are available are you have a donor bike. Now is it worth the time & $$ is a completely different topic altogether lol. Sometimes to create content as a RUclipsr we do spend more money than it is worth to fix. I personally hate seeing quads & bikes go to waste. But $$ plays a big factor sometimes.
I was given a Yamaha grizzly 660 and a grizzly 125. I haven't received them. Buddy went through nasty divorce. I will get up with you when I get these in my possession. Thanks for the great videos
Where do the red wire and blue and white wires go to on the selenoid
Those would be your trigger wires for the push button start. They should just plug in right near the mounting point of the starter solenoid. I can remember if they are individual bullet connectors are if it's just on connector.
We're u located
Hey David.
I am located in Southwest Missouri in a town called Ozark
