YFZ450 Engine Noise... is it Serious? Lets Find Out!! (complete with comparison) 

You should have shown what it takes to separate crank and install new bearing! 💯

Its so hilarious how these engines just naturally sound like a bucket of bullets driving down a dirt road.

I would like to see more of this😊👍 And if you want to document the rebuilds also im not complaining😁 Happy to hear that you have reached 1k subs. I hope you and yor family have a nice summer🌞

Love the videos do you have a shop name that I could have a motor rebuild by you just was wonder for future? not many good mechanics out here we’re i am from and you are verry organized and do clean work and I do appreciate your videos.🤙

Bro this is the best video I've seen on the yz450 engines can you please do the noise test on your yfz with it in gear?

Kick ass work sir

I miss that sound. I had a 2007 se 450. Dasa full exhaust sounded awesome

6:15 i have practice with mx bikes. Even if connecting rod no bending and you side dimensions within manual limit, after inspecting you can find damaging bearing on connecting rod. So, thats why you should always stay with service limit (engine hours). Even if it looks good.

Didn’t show the most important part… the rebuild lmao

Hey man great video! Im having issues with my 08 yfz 450. Its got a tick/knock and i cant seem to figure it out. It also sounds like something is loose

I just got a 2024 yfz 450 se yesterday and I did 3 heat cycles one this morning and I let it cool down turned it on to let it warm up took it for a ride not even half throttle,not pushing it not keeping it at a certain rpm when I shift to 2-3 it does like a clunking noise I hear it top end took it to the dealer they said it was the chain From the sprocket getting adjusted? Is this normal? Goes away higher in the rpm idle and start it is good and starts right away. Any ideas so I can get a peace of mind lol

I do a top end repuild i have 07 year yfz 450 and i have in it athena big bore kit and i put it in wösner stok compresratio piston and new cam chain and its sound very loud knoking i chek rod and i dont Feeling any play in whats is in my motor

I'd check the valve clearance 1st. I had noise like that in an XR600 and the PO had the valves adjusted about 4-5x wider than spec.

I would love to see how u replaced it u really did show anything sucks I really wanna watch more of this and more videos hope they are not like this one.

so what did you end up doing bearings new rod ?

How much does that work can cost?

If there is shavings on oil filter does that mean it’s gonna blow soon? I just got my motor rebuilt and on the first oil change after the break in there was shavings

i got also a problem with my nerfbars by riding my yfz. very hard vibration by my feet.. anyone know what it can be?

I've got AYZ450F 2009 and sometimes it sounds like crap, And other times it sounds fine? Anyone have a idea. Thanks in advance
