How To Adjust the Valves on a Yamaha Raptor 700

Checking and adjusting the valves on your quad is a part of regular maintenance, but tearing into the engine on your Yamaha Raptor can seem like a task that's too big or scary to tackle in your home garage. With the right know-how and a little confidence, this job can be knocked out in a few hours and save you a lot of time and money down the road. In this video, Charles shows the proper steps to check valve clearances and adjust the valves on a 2008 Yamaha Raptor 700.

Would it be bad if I didn’t change the o-rings. My quad only base 15 hours on it….. I appreciate it thank you !!

[@danz1910]

thanks brother

Nice video I got a raptor 660 2004 how do you adjust the fuel screws?

[@noahhanson9009]

Great video but I can’t loosen my valve jam nuts they will not budge at all

[@salamalwan7578]

If I adjust the timing chain, do I have to adjust the valve?!
Now I checked my 2018 Raptor 700, the lines are not parallel to each other.
But there are no faults or phenomena in the Raptor, it drives properly and does not falter and there are no phenomena whatsoever.

Hi!May I ask you a question? I don't know what the previous owner did, but when I try to bring the piston to TDC aligning all the marks, it will close the exhaust valve and after passing the TDC sign, it will start to open the intake valves.This looks like 180 degree offset.
Do you think the camshaft was modified?

[@rmatvmc]

Turn the crank 360 degrees and that should bring you to TDC Compression. Sounds like you were TDC Exhaust, 360 out on the crank, 180 out on the cam. -Charles ua-cam.com/video/Tizc5y1wijI/v-deo.htmlsi=SfvDOs8-6IWUSeJv

Can or do yall have a video like this for the 660R

[@azxp]

Do you guys sell a parts kit for this? Can I just order this without looking all of those parts up? Also those valve tappet tools are a bit of alright.

[@coltensmith1897]

You guys should show examples of what it'll sound like, yeah it's not hard to tell all in all but it's nice to be fairly sure

[@benbush5183]

No shit, exactly what I was thinking. You find a better video for a 700r with sounds?

[@coltensmith1897]

@Ben Bush yeah, I did but the guy doesn't explain how to tighten them, he just shows what it sounds like when the valves are loose and how they sound within spec. The first bit is out of spec the second is after they've tightened them. ua-cam.com/video/kSdEIb9IsCo/v-deo.html

Mine is getting hard to start and it’s been popping for a while. What should I do if it’s still popping? It’s fuel injected. Also it shuts off randomly so hopefully this fixes it.

[@luiscornejo1481]

If your bike is popping it may be needing more octane gas, a higher octane gas will be better for predetonation. It may be in need of a tunner if you have aftermarket air filter or no lid, aftermarket exhaust or no silencer. Basically the bike is tuned for stock form and any alteration will cause popping in the muffler or internal. Either way it’s something you want to address sooner than later. Valves can be burnt and excessive heat will be noticeable.

[@darrellchristie2445]

Great another video that doesn't tell you what size the tappet screw is, to know which tappet tool to buy! 3mm? 4mm?

[@rmatvmc]

The tappet tools we show in the video came as a kit, and was affordable when it was available so we didn't specify. The manual lists 3mm and 4mm tools, but to be sure, I would pop the covers off and measure. -Charles

[@jesusjacobo1156]

Did you ever find out if it was 3mm or 4mm? Want to buy it but no clue what size to get.
Thanks in advance!

[@420kayoe420]

what is a good spark plug to use? can u use any type? also is it necessary to replace it if its a new atv only run for about 20hrs?

[@gregorywilliams3533]

Ngk

[@Flores97Drummin]

Check out cuervos video on here about spark plugs

[@curtnewcome54]

Ngks!!

[@luiscornejo1481]

We use NGK CR8eix it’s the iredium “upgrade” CR8e is stock copper I believe. Both are acceptable. If bike is stock it needs no more than factory recommended. Our intervals are around 25-30hrs on average

[@jesusbotello6881]

Is it the same on a 2021?

[@rmatvmc]

Some specs may be slightly different but this video can certainly be used to adjust the valves on the 2021 model.
