We all wish we were surprised but honestly, not really.

I am trying to do this on my bike now and I've gotten almost to the part where i can remove the carb. I cannot figure out how to remove the throttle linkage from the carb though, its a circle with cables on the top and bottom of it which rotates when the throttle is twisted. Probably the same as the one in the video. How do I take these off?

а я думал у меня трудно снять)))

Engineering…”but you’ll have to remove everything to get to the carb…No they’ll have to” Problem solved.

Hi, do you know what size are the vent hoses that come out of the carb? Is it 3mm or 4mm? Thanks,

This is insanity

Quality video. Just wish it wasn’t sped up so much because some parts were hard to see as it is.

No way it’s that easy, I have been paying way to much 😩

Awesome vid. Thanks much

If the valves need to be shimmed , with the bike have low compression

Nice video. Clear and concise. Easy to follow. Great!

hi, why does the 7.48mm OD shim actually measures up to be 3.74mm in diameter? (1/2 the size specified)

I'm adjusting the valves on an '04 CRF450 I bought recently and one intake valve has no clearance. When I calculated the shim size I need it's not available thru Honda, I need a 1.10mm and smallest they sell is 1.20mm. I'm guessing I need to pull the head. Is it possible the valve itself deforms or is it usually the seats that pound into the head?

Hugley helpful thank you for all the detail. It was my first time doing the carb and I wouldn't have gotten too far without this video.

Hello there, question for you since you are well versed in Honda CRF’s. I have a 04 that idles fine and sitting it will throttle up fine however when I kick it in gear and try to take off it will bog down really bad and almost shut off. I checked the accelerator diaphragm which seems ok, any suggestions on what to check next? Thanks 🙏, great videos btw they are a huge help.

Tried adjusting the valves on my new to me ‘04 yesterday. The cam lobes were at the 180 degree position from where they are shown here with the piston at TDC and the right side timing mark lined up. Anybody know what the hell I’m supposed to do? It’s not measurable from that position, as the exhaust rocker is tight when I measure it there.

I think I have this right now, if the clearance of a particular valve after 20 hr riding is .004'' , and we need .005'' to be in spec, we would use a .003'' shim to bring it to spec. Using mm's for this job may be incredible for the Japanese, but for me it is much more work when it could be so simple using SAE.

7:02 You're making so much easier than everyone else for calculating the needed shim. Shame the don't make available SAE shim sizes. I think I'll mark the equivalent sizes in shim assortment case. I would guess that the bulk of the CRF R And X models sold are sold right here in the US.

5:40 Seems like great info so far, but it's pretty scary to see all those shims sitting in an easy tip over tray right over the top of the engine.. lol

I’m having trouble putting the throttle cables back on

Thank you for the video brother never done it in my 04 crf 250r but after watching your video i will do it my self great information u gave us

dont need to do that mate just take out bottom bolts and losen the top it will lift up then tighten the top ones the half frame will stay in place ,when ya done losen the screws drop it back down put bottom bolts in ..ya dont need to take full frame off just take bottom nuts out and losen top ones and lift it then tighten to hold in place while you work,the frame will hold in place lifted up

Thanks for the video. I have the same boat. I am going to try to do the service myself. Can you please share the parts model # and where you purchase them. Oil used? Filter? Impeller? Thank you

Thank you! I just bought a Honda 2001 cr250r and it had bad gas so I cleaned out the tank and removed the plastic too and, it was a bitch to remove the carb. Thanks man

Are the oil and transmission sides separate? I'm only wanting to change the engine oil at the moment but somebody told me they are connected.

Thank you for the vid! Hope I can get the air boot on tomorrow!

Nice job! We just did a similar video about the oil change on our Nautique - so RUclips suggested your video to us. :) I wish changing the oil in a car was as easy as changing the oil in our boat. It always seems the filters are in horrible places, and the drain makes a mess. I like that nice drain hose and the easy-to-reach filter placement on these nice V8 boats.

Thanks for the video

Just got done pulling mine man what was Hondas engineers thinking.

You have explained this in a very easy way too do, a lot of people are put off with video that starts going on about measurements to work out the right shim size this method works perfectly well and makes it easier for people to do themselves, well done 👍.

Looks like a nice little project I got into

Great video just bought an 06 250x qnd it's dumping gas as soon as the gas is turned on

The more proper way to do this is to measure your gap, then pull the shim and measure the shim with a micrometer. Do the math to see how much less/more shim you need to be back in spec. Only have to take everything off once.

Awesome video man

Brilliant. Thank you sharing. Keep em coming !

Hi, thanks for the vid. My kid's 250x has all that milky white goodness in the crankcase. We drained it. Oddly, the radiator is completely full. I wonder if water got into the engine via the oil plug, as it appears to be stripped as opposed to the head gasket-- anyway, do we need to strip the engine apart to clean it or is there a way to flush it? Thanks.

by far the best video ive seen on this process yet, thanks for giving me a clear understanding

Good lord. Step 1.) disassemble 75% of bike. Step 2.) remove carburetor.

Helped a lot ! Seemed to easy to get out with the video! Thanks

Great video. thanks for the help.

By far the best video on RUclips by far on details about valves!!!!!!! Thanks man

So I can basically put a shim in until it’s matches with my spec like put a shim in test it if to tight need smaller shim to loose bigger shim but it’s have to be in spec

In other word to tight means smaller shim to loose means bigger shim

Thank you for taking the time to do this vid. It’s perfect 👍

This is so helpful. It deserves way more view and likes. Thanks for doing this. I subscribed just to support your channel whatever else you cover.

Bikes sat too long in my box trailer! Bad gas and wont start!! What a pain to remove these carbs!!! Thank you for taking the time to show people the proper way to remove and replace these carbs!!

Thanks for you crf valve vids, my bike is difficult to start. Off to garage and see if this is the problem..

How the hell does a 450 run with the Cam 180 degrees out 😳🤨 Well it does run but, yeah I don't understand how when everything is opening and closing at the wrong time Has damage been done 🤔 Guessing some cabbage put the cam in backwards on last shim job Or can the cam spin 180 degrees out of spec 🤔 doubtful Buy used its always a fun learning experience 😳😁🤣

Great video mate, perfectly detailed. Well done.
