My buddy spent thousands on his Raptor . Eventually I got it after numerous other shops and individuals. No matter what I did I COULD NOT get the timing to line up . After numerous attempts I knew something wasn’t right and ripped it back apart . CAM WAS BENT/TWISTED. Got a new one BAM 💥
Hey Hunter, thank you for the perspective. It helped me get my camshaft oriented. I had the camshaft sitting in the journals 180 degrees off initially too. Maybe you have a different cam sprocket, but there are no imaginary holes. The cam sprocket does have three dimples (punch marks) which should sit at West, North, and East respectively. The North dimple (punch mark) is covered up by the decompressor guide, when installing the sprocket bolts. The decompressor spring lever with its projections (pegs) also has a dimple (punch mark) that is supposed to sit north. It is all in that manual if followed correctly. You are pointing directly at it all 1:51
If you use a piece of wire instead of that socket extension to hang the timing chain when you remove it from the camshaft, it won’t fall down and come off the crankshaft. Saves a lot of headache when putting things back together. Especially if you are removing more than just the valve cover.
It's all I had next to me to stick in there lol, the last 4 wheeler I did this too, I used a zip to to the frame above to ensure it kept the tension on the chain so it wouldn't fall off the crank
Hey man I have a 2005 raptor 660. Will the timing cause it to bog down on a load I have tuned the carburetors to the right spec but it’s still doing it. Could my timing be off?
Mine only smoked on the first started up because of the all the lube I used for the cylinder walls, it shouldn't be smoking (really it shouldn't at all) more than a few hours of time on it to ensure proper seating
Hey there hunter’s mechanic, did u get my mesage earlier today regarding the atv. Same bike 2001 raptor , same niche kit. When I have spark plug in it , engine won’t turn over but twice , I get 120 pounds compression , and turns over a lot with spark plug out , why won’t it keep turning over after 2 times with spark plug in ??
I replied it to but I don't even see my comment, must not of had good signal when I did and it just didn't upload.... I believe you mentioned using an ATV battery to help jump start but have you used a vehicle battery? I keep a truck battery in the garage to jump mine in case I need it. Double check the ground to the case, it should run from the battery to the left side engine cover. My starter wouldn't turn over damn near at all when it was dirty and it also smoked 2 of my starters.... worst case scenario is that your Camshaft decompression pin man not be working. When you are starting the engine, the camshaft has a small pin on it that decreases the cylinder pressure and once it fully starts, that pin returns to its position for full compression. I know a lot of people that watch my videos have the same issue and I never knew about it when I made my videos. @danil1581 has a video on that decompression pin on how it works. If you find no solution with another battery or cabling, thats where id look next. Let me know how it goes!
@@Hunters_Mechanics yes I think this is my issue as well , that decompression pin sounds like the issue . I get 2 good strokes to fill up the gauge and then it’s not releaseing compression like u said to let turn over anymore , I pull spark plug and it moves fine , yes I am using a vehicle battery to give it more juice as well
@@glendane8625 Then that's what it sounds like to me. Knock on wood but I haven't had any issues with mine but everytime I have removed my cam I have cleaned out the journal holes and made sure that the spring and mechanisms still work on the front. If you do take the cam out, don't forgot to zip tie the cam chain up so you don't drop it in the case 😉😂
Hi can you help me i have a 02 raptor 660 but the problem is when I put oil on the reservoir the oil go through to the Carter I put 4 liters and the oil stick doesn't mark nothing. With the motor of so the motor is not running an the oil go directly to the bottom fron the reservoir. Do you know anything about. Please let me know 🙏 😔
Go watch my oil change guide, it may be able to help you out with adding the oil and making sure it shows up to the correct level ruclips.net/video/urPOpS9DiOE/видео.html
Hello! Great video thank you very much! Just had some questions, I tried my best to follow along with the video and after starting it up the piston now touches the valve. Any advice would be appreciated!
You might have the cam 180 degrees off, any time the Cam timing is off is when the valve would hit the piston. Ensure that when you are putting the cam in that the crank is lined up with the slit, and that you have the correct "pin" and oil galleries facing upwards on the camshaft, otherwise the timing will be wrong
Cam lobes down and three pin holes you should be able to see. Also his timing chain is super wore out of he can rotate the chain without taking the cam sprocket off. Put the cam in and then the gear. Adjust accordingly.
@@netflixnchil421 its because the tensioner is not in, with it it, its extremely tight. Even when that chain was brand new I was still able to do that method
Have you checked the voltage while the ATV is running? I have the Raptor 660 Manual in the description so if you want to download it and look in the back of the PDF, it has a section on troubleshooting the entire charging system of the ATV
I truly don't know what the H is supposed to be, I'd assume it's supposed to be 10 degrees before top dead center for ignition timing but don't quote me on that. Just use the "I" and you should be fine
You said you put on new carbs was there something wrong with the old ones or did you just change them? Still having trouble with backfiring and carbs blowing off boots when cranking. Timing all looks good unless its off just a tooth but would that little bit make it do that? Just asking to see if there could be another issue ive overlooked. The bike just cut off one day and has been doing this everytime i try to start any ideas would be appreciated.
@@roycesands5475 When my 4 wheeler timing was off that's what caused mine but my timing was off by 90 degrees. I wouldn't expect the 4 wheeler to lanch the carbs out with only one tooth off but I've learned that, that specific engine is very very picky. I bought the new carbs because the old ones would not stop flowing gas out of the overflow even with two different rebuilt kits having a new needle jet, so I went ahead and got new carbs on amazon for $45-ish and they have worked much better and have alleviated some headaches. Like I've told other people, did you ensure that you used the correct indents on the cam to set the timing? Because that's how I ended up being 90 degrees off.
@@Hunters_Mechanics yeah man i tripled checked the timing was right its all lined up i took like a hour and a half to get it just right and its still doing the same thing i even did the vavles twice but the middle valve had to set alot lower than the rest i think it could be stuck open. Is the only way to check the valve is to take off the whole top end? And would a stuck valve cause backfire and the engine to roll over faster than normal ?
Some one can help me with my raptor660 2005 I just changed the piston, the rings and the seal valves exhausted the clutch but when I finished the engine is running but very hard
You are actually incorrect on your cam the third hole does exist if you remove that little cover that's in between the other two holes on one side or the other there will be a third hole covered up by that plate on your cam gear
If they do ive never seen it lol I feel like they don't because you have to use sealer around the cam bearings in the middle of the valve cover, no way to use a gasket to cover it
Hi mate I do have a problem with my timming chain I changed it with the new one same method as you but . It runs well on neutral but when you tried to accelerate is stat poping . I've no ideea why
Hunters Mechanics yes i did I thing one of my exhaust valve is bend because when i had the old timming chain it was too loose and I think it jumped one tooth If the engine it's cold works fine for a few seconds and after that starts poping.
@@chissebi8772 Did you do any sort of leak down test to see if the exhaust valve was sealing properly? If it's not, it could be losing compression and be the main cause for no power, I'd get a compression checker and see how much your engine is pushing out.
@@Hunters_Mechanics Thanks alot Hunter I think my chain has stretched it's pretty lose after I put in tentional , it fires but its miss fire until I spin it a few time then stop firing all together every time I reset it , it Sparks a few times then stop
@@tonymagee8500 the chain should be TIGHT tight after you put in the tensioner, if its not grabbing hard, it can cause the timing to slip and possibly cause piston-valve collision. If you have significant play after the tensioner I would replace the chain
@@LifeofAedan I just assumed that it was the stock one for the 2001's, It was on there when I bought it and I honestly can't find one similar to it online
yo have a 2001 raptor that m trying to time but the problem is ill time it on "i" but when rotate to the engine on the crank shaft 1 full turn, the cam only turns halfway, so like one full bottom end turn only turns the came halfway, any ideas?
Thats the way all engines are, crank and cam are a 2:1 ratio, 2 turns for the crank is one turn for the cam. As long as the "I" is lined up when you align the cam wheel, it should take 2 two turns to get back to your starting position on the cam
@@Hunters_Mechanics I did align the i mark but I mean I align the i mark, turn it over, snd than realign the i mark and the lobes are upside down, so does that not affect the timing, like if the lobes change postitions after 1 turn to “I” than shouldn’t it not matter which way you put the cam in?
@@Hunters_Mechanics actually I should say, so what’s stopping me from putting the cam with the lobes facing upwards instead, since I can just turn it over on the crank and it’d be at tdc and the lobes would be down
@@austin_colt bruh I’m honestly considering it lmao I really don’t under stand what the difference between me just putting it in down wards or upwards Bc everytime i turn it to tdc they flip postitions
tizzee11 they stuck. Bought a 660 used that had a brand new rebuild with paperwork from a shop and hour meter. 5 hours in it blew. So I rebuilt it myself with the niche, got about 9 hours out of it. Rebuilt it.... again with stock Yamaha parts this time, and now have over 200 hours on it
niche sleeves drop down and let water in, you can either take off a little on the jug and get it back to flush with the sleeve or get different brand of barrel...
After I set top dead center then install the chain tensioner the punch holes are no longer sitting flush with the deck. No matter what I do I can’t seem to get it right. Any idea why that would be
Can you move the cam wheel slightly and get the hole to line up before setting the tension? Because like I stated in the video, it might not line up perfectly, if you can get the punch holes to line up before you set the tension then you're all good
Your little dimple that you point out on that camshaft is the decompression system for that atv,the 08 honda trx700xx also has a decompression system on the camshaft but different, just so people know that's not a dimple and that's the atvs decompression system,not trying to be an a-hole....
But is everyday people going to know it? No, thats why In every video I try to ensure I use the simplest terms so people who don't know everything about engines can follow along.
Hey man I put my new cam chain on and the tensioner or the black stick isint on but the chain is really tight and won’t pick up and a lot of compression when I turn to align the I mark what do you think is this issue
What does it not pick up? And it's going to have a lot of compression when turning it over, you can take the spark plug out to make it much easier to turn over
@@crfisaiah3963 so you do no have the chain guide (the black slide) nor the tensioner on and you cant pick the chain up at all? Like not even a little bit? When you turn the engine over with the bolt down below, does it turn the chain and cam? (To ensure it's on the gear down below and not the shaft) because it's supposed to be moderately tight regardless, that's why you have to tilt the cam towards yourself to release a little bit of slack to move one tooth forward or behind
I took my raptor to a guy that said my timing chain was off and that it was “stretched” so I took the top end off an put it all back In dead center and I put everything back together an still won’t turn on, you think you can help me out?

This is why your timing chain snapped and this is not good info to give people sorry .. you need to bolt the Rocker Cover down before you put the tensioner in or you will stretch the chain
The manual specifically states after installing the cam and the timing chain to install the timing chain tensioner..... I've never had a timing chain break on any atv I have changed the timing chain on nor had any issues with them.
Like I tried to state in the video, if you get the cam gear to line up the dots with the surface, that's all it needs to be, when you set the tension it will be a little off, as long as BEFORE you see the tension it lines up, you're golden
Snap 358 was your timing right? Mine is doing the same thing...I spent hours messing with it and trying different teeth to compensate then eventually I found this comment and said screw it
This video is a life saver. Im currently rebuilding my raptor 2005 660 and have everything apart. This will help when putting it back together!

@@Hunters_Mechanics lol but other then that good vid!
Can u plz help
This is why your timing chain snapped and this is not good info to give people sorry .. you need to bolt the Rocker Cover down before you put the tensioner in or you will stretch the chain
The manual specifically states after installing the cam and the timing chain to install the timing chain tensioner..... I've never had a timing chain break on any atv I have changed the timing chain on nor had any issues with them.
Bro i CAN NOT get the cam gear perfect. As soon as I set the tension it’s off. 😂
Like I tried to state in the video, if you get the cam gear to line up the dots with the surface, that's all it needs to be, when you set the tension it will be a little off, as long as BEFORE you see the tension it lines up, you're golden
Hunter's Mechanics thanks I really appreciate it.
Snap 358 was your timing right? Mine is doing the same thing...I spent hours messing with it and trying different teeth to compensate then eventually I found this comment and said screw it
