Just picked up a 426 with low time… previous owner brought it to a ‘shop’ running…. had a hot cam installed- now not running. Subbed! 😎Thanks for the help, working on this one next week😊
Hey I have a new hot cams timing chain with my new cams and it's very very hard to get onto the cams cuz it's so tight I understand what your going through I had to put my cams in a certain way it was hell idk if I have it timmed right I over tightend my cam caps so gotta order new ones 😭😭😭
@@motorcyclefixer thanks. I was doing research, and read that 06 and till now have bigger bore. Old ones had 426cc, now they have around 449cc if they are not factory racing.
Hi When you say slightly off are you talking just a quarter of a tooth. sometimes it's impossible to get it perfectly straight and the bike should run fine as long as it's as close as you can get it. If it's not "close enough " then consider purchasing a new cam chain I hope this helps
Morning sir, I have yz426 but the block is damage,it is pit sir the block of wr450 to 426 celinder head ,,wr is 4 stad bolt and the 426 is 6 atad bolt.
i don't know sorry. there are many things that can affect this. diameter of the bore. stroke of the piston. configuration of the bolts etc. etc. without having them side by side and measuring everything i would say probably not
I have a wr426f do I do the same with it when timing! And idk but I Hurd that you need 13 pins between the two Dots for the Wr but if I do 13 pins then the Timing is off, also So you do check To see if the timing is correct when The cam chain is tight not when lose
When it's tight Put your finger in the hole and push on the cam chain guide to tension the chain while you're setting it The most important thing is that the dimples are in line with the top of the head

Thank you for your comment! Good luck with it
I’ve watched several other videos on this procedure and found your pace, techniques and simplified terminology to be very helpful.
Thank you very much
I'm glad to have helped
Hey this is the best video for setting the camshaft timing. Especially with the E and I marks on the camshafts( Exhaust and intake ).
Thank you for your comment
My tensioner is loose but my chain wont get as loose at yours and i cant time it what is going on its a oem chain

Oh no 😪
Best of luck with it
Did you take the tensioner out completely
Also check the bottom sprocket to make sure its on there properly
Is it same for YZF 450 2005?
I'm not 100% but it will be similar with marks to line up with the head
@@motorcyclefixer thanks. I was doing research, and read that 06 and till now have bigger bore. Old ones had 426cc, now they have around 449cc if they are not factory racing.
So im not really sure, maybe they had to reinforce cams, cuz the engines were constantly getting too much fuel and they would "drown"
Great tips as usual. Simple to follow
Thank you my friend 👍🏼
Hello, can you adapt the 450 cylinder to the 426?
I don't know a definite answer I'm sorry
Thank you so much. Please keep the wr400-426 etc
I am doing everything like you are doing and my timing is ending up slightly off after putting chain tensioner on. Any advice is greatly appreciated!

Morning sir, I have yz426 but the block is damage,it is pit sir the block of wr450 to 426 celinder head ,,wr is 4 stad bolt and the 426 is 6 atad bolt.
If it's a WR then it would be a 2 stroke
Do you mean WRF 450 ?
Do you have a video on how to adjust the timing on a 2018 Kodiak 450?
Sorry mate not yet
Morning sir,,can I ask sir that block of wr450 ,it is pit to Yamaha 426 and the head of 426 is still remain?

Hey could you do a video on cleaning the carby on the yzf426
Hi thanks
For your comment
I'm afraid I have sold the 426 now
I'll see if I have a similar carb there if not I'll do one next time I do
Thanks again

What happens if mine cam don't move as much as yours?
Hi
Move in what way
The time is the same in the wr?
In the wrf it should be yes.
Thank you
Thank you for your comment. I'm glad yo found it helpful
Thanks bud.
No problem
Glad it helped 👍🏼
great video
Thank you
I hate messing with the cams they’re so annoying
I gave up on my 426 and hired a pro 😂
Sometimes its better to ask for help 👍
Hello boss question does the wr426 engine fit the wr400 frame? Are both motors identical? Appreciate it
Hi
I'm sorry I don't know for definite so I can't say I'm afraid
All the best
