Great vid and good detail . Valve stems loose their clearances over time from the valves going farther into the head. hence getting closer to the rocker. You'll end up overheating the valve and the valve head will cup. Therefore the adjustment increases the gap back to normal clearance measurement ,so the valve can close completely, properly, as it is suppose to do. A little valve noise is better than none. Just my 2 cents. cheers!!!
Great how to! Great showing how to keep the area you're working on CLEAN which is important in this job! Had the same bolt break on my recoil, too. Yeah... I have to adjust the valves on my Grizz... Very well done and handy video, Mike!
Watch it with the timing marks at 10:00 : there is a 50% chance you are NOT at TDC but it could either be the beginning of intake, or the beginning of combustion. Make sure the piston is in compression, and NOT in exhaust cycle.
You could've saved yourself the hassle of that broken bolt simply by understanding you do not have to be on tdc to set the valves. Anywhere on the compression stroke will guarantee that both valves are closed and you're on the flat side of the the cam lobes.. Simply rotate motor in the direction it runs until the exhaust, then intake both open and close and rotate a little more until you feel the piston coming up (compression stroke). Use a long screwdriver to verify.
Do you think using your impact driver fairly gently and some penetrating fluid maybe the day before would have prevented that cover bolt from breaking off? Just wondering. I have a 2005 Kodiak 450 with about 4300km on it and I will have to do this soon.
Yes anything like that would help. I would still use concentrated heat with soldering gun combined with those ideas. Even shocking the bolt with a drift and hammer too.
I see guys in these videos setting the crank to TDC . by the book, that's correct, but technically all you have to do is make sure the valve is closed. The crank position doesn't matter.
I pulled off the front plastic only because there is a bunch of electrical issues on this 2004 Yamaha Bruin 350. Can you post a video of the electrical system at the starter relay?? Unless I provide direct battery power to the relay, the starter will not engage. This is a brand new relay and it does pop when power is applied...thanks
limpieza profunda 😁 happy to hear it may just have been too much oil! .... I tend to always fear the worst! Greetings from Canada 🇨🇦 back to you my friend and good luck with the valve adjustment!
Setting the valve clearance is a great place to start for your backfire issue, In Particular the intake side. As far as the vibration that would most likely be unrelated.
@@mikeomax8101 remove the belt and see if it goes away. Try and figure out if engine or driveline. If engine maybe worn crank bearings? Just guessing it be driveline related though.
That’s a great idea to remove the front wheel and strut to gain access to the exhaust valves.
Glad that helped you!

Thanks for the vid, i was about to pull my whole front fenders off to do exhaust side lol
Good job on the video best description I’ve seen yet. Sorry about the broken bolt hope you get it owoot. 😉
Thanks! 😁

Yes excellent point! I explained that later in video at 22:00 roll the engine until you see the intake valve drop and then bring it up to tdc...
@@bikermike You will be able to feel the arm jiggle up and down a bit too I think
@@eclipser2004 yes you will but needs to TDC for proper clearance.

My 06 backfires on deceleration a fair bit. Scares the heck out of me lol. I will give this a try . Thank you
Having same problem on my 2004 + some engine vibration on higher RPM. Does this adjustment solve this problem?

@@bikermike Thanks for replying!!
Thank u so much . Cheers from Manitoba
No problem! Glad it helped ya out! mine runs much better with the valves set properly now. Cheers from Ontario!

As long as the rocker isn’t ramping up on the cam, valve could be closed but still could get false clearance measurement.

I no longer have my Kodiak. Not familiar with the Bruin. Sounds like relay is not getting voltage from starter button circuit?
Check with test light on relay input side
Do you have a video on how to adjust the timing on a 2018 Kodiak 450?
No, Sorry. Sold this quad too.
Would it need adjustment? Did the timing chain slip? Probably wouldn't run if it did I'd say
@@eclipser2004 the engine actually needed to be rebuilt, it wasn’t the timing chain, even though it slip out of time.
Before the T mark i see F mark ???
Very nice bike, great info
2 things, heating the bolt will expand it. also, you didn’t mention what stroke it should be on.
Heating the bolt will help loosen the corrosion. Top dead center after the intake valve cycles.
@@bikermike thanks
Heey ...do you know which can be the problem when the hose from the top of the timing chain is leaking oil inside of the air filter box?
Sounds like crank case is building pressure from blow by. How may miles on it? Perform a leak down test on it. Could may be too much oil too.
@@bikermike thanks...the oil was very high and very dirty...I`m adjusting the intake and exhaust valve now...REGARDS FROM MEXICO!!!
limpieza profunda 😁 happy to hear it may just have been too much oil! .... I tend to always fear the worst! Greetings from Canada 🇨🇦 back to you my friend and good luck with the valve adjustment!
Wheelies will cause oil to go up into breather box too

@@bikermike Any suggestion what may cause vibration? Not the engine mounts.
@@mikeomax8101 remove the belt and see if it goes away. Try and figure out if engine or driveline. If engine maybe worn crank bearings? Just guessing it be driveline related though.
@@mikeomax8101 check all universal joints and wheel bearings for excessive play. Wheels and tires for trueness
So when its at TDC the adjustment is the same for both intake and exhaust valves?
the specifications are on the air box lid if your asking about the measurements. The procedure is same just the clearances are a bit different.
biker mike i mean when you put the engine at TDC. When you adjust the intake valves you don’t have to rotate the engine to adjust the Exhaust valves.
NightHawk J30 that’s correct if your at TDC on the power stroke your good.
biker mike ok thank you ill have to do both the carburetor again worn out float. Plus it needs a valve adjustment.
how many miles and hours are on your 450
3,000 miles. 275 hours.
biker mike nice mine has 1300 miles good to know they can last that long iam a hard core Yamaha fan
@@workhard3994 They definitely make some great lasting products! A buddy of mine has 24,000 miles on his Kodiak 450!!!
work hard mines got 1000 hours, 5100km did an oil change last week for the first time in a long time and gas an oil cane out😅 only like 100 ml
work hard they are bullet proof, I got a 2003 never had a problem
i love this niggas accent. subbed.
My same bolt broke dam
I think its a common issue....
💔💔💔
