There's a lot of people commenting on here that don't know what they're talking about. 450 motocross bikes have automatic compression release cams to make them super easy to kick over.. that's the whole point. Also, that "knocking" sound is the chain slapping, tighten it up. It does sound like it's a little lean.. check for leaks at the head pipe where it connects to the engine, and same for the air box. Seems to run good otherwise.
The decompression valve definitely doesn't make it "easy" to kick over, that engine seems pretty hashed. There's no way a 120lb kid should be able to kick it over that easy
Bike is running lean, check timing the popping is a sign of lean or timing is off a little. The sound u hear is the chain hitting the chain guide mine does the same thing
The kickstart lever needs to be readjusted to it's original position, it's been worked on, it needs to a little more forward, it will vibrate on that twin spar.
Congrats on your good deal. Heads up, don't blip the throttle when warming it up. Just let it idle until you feel the top of radiator get warm to touch. Did you know the main cause of engine damage occurs at start up because of improper warm up techniques and oil lubrication?
It colloquially called "cold seizing." (Seizing a cold engine) Saw a KX125 rev his bike cold to impress his girlfriend...we all could hear it seize...the engine coming to a permanent halt. I ALWAYS ride my bike just above idle for 4 to 5 minutes to warm it up. Good for 120 engine hours...easy.
mine was a 2002 which i believe was the first year for these 4 stroke 450r's,the only thing i hate about them is that you constantly have to shim the valves which is a pain in the ass.they are super expensive to do a complete engine rebuild on,it cost me $2500 to rebuild the bottom and top end.i ended up breaking my femur on it my very first track race which was the start and finnish of my race carreer
@@microsoftteams2663 yup,it was a nasty one,no pain at first until the adrenalin wore off hours later,went home and to bed and woke around 3am screaming in pain,went to the hospital and they took me in for x-rays and gave me a shot of morphine straight away,i was laid up for the entire summer and the worst was,they wouldn't operate as the dr told me the last patient with the same injury they put screws in him and every time he moved they screws would pull out so they just let it heal naturally.i still have a big chunk of bone moving around on the ball of my femur where it meets my hip and rain and cold bother it.the hardest part to accept was i was in 3rd place and catching the second place rider and we were on the second lap out of 3 so i may have made the podium on my first race ever.
Two and a half years ago I broke my right fibula two inches above the ankle. Took two years for most the hardbone healing to normalize, to diminish. I can't imagine how bad a broken femur hurt though!!!!
@@microsoftteams2663 u can see the accident on my channel,just look for the one about the motocross track,there are over 400 vids on my channel so you will have to scroll thru them but youll get to see how it happened,i got hit by a 300 lb rider and his bike while picking my bike up and its my bike that saved me or id probably be dead now
John I think it's because he didn't do a full kick. My buddies 08 yz 450 has no compression unless you let the kick starter all the way up and get the compression stroke. Also don't the exhaust cams on those have a decompression weight?
Landre Porter definately an inch or two too small. Ussully the top of the tire sits above the fork seals. It could also be an optical allusion due to forks being completely draned of oil?
I'm not sure if you still have the bike but it sounds like the cam chain tensioner went out. I recently had the same issue with my bike and it was a $20 fix on ebay. Look into manual cam chain tensioners vs the auto adjusting. The oem honda tensioners tend to have short lives.
want that 04 to feel like a 2 stroke. get an 04 hrc cam for it. u wont believe how much more power it has and it revs out like a 2 stroke. i owned the 04trx in 04 was first at my desler with hrc equipped. my friend bought 04crf like u have crf had few mph more topspeex but the hrc equipped trx had so much torque was unbeluevable. no other csm ive tried came close
Great to see this CRF. You guys sound like my two boys - always having a go at one another ahaha hope the bike worked out for you. I plan to get one for my boys.
That bike is bound to blow up if you keep running it, that knock is probs the timing chain, it backfires ALOT, and there is white smoke... rebuild it before you fuck the bike up even worse
I wish I were this young and could try one of these. Must be a special feeling when you are so young. Or am I wrong? I never had a moped when I was 15. Now I soon turn 50. I am probably older than the guy who is talking in this video.
That bike has definitely been abused and the compression is low/valves are bad because the compression seems low for sure by kicking it over with sandals. 450s have VERY high compression. Motor is more clanky than a coin purse too.
Late reply I know, but completely agree. I have an 07 and there is no way it kicks that smoothly... it's near impossible, but, it is in a kart 😜😎 ruclips.net/video/_2oSY_SMiGA/видео.html
probably has auto decompression valves and when starting it kick it down a half click then all the way back up then kick through hard should start first kick almost every time.
man they treat it so wrong. Never give gas when a 4 stroke is choke on. And a 450 is NEVER easy enough to kick in sandals. Plus something doesnt sound right with that bike. Maybe the Timing?
Jakelols Gaming not just with choke on, never gas a 450 while kicking, it will send the Kickstarter flying forward when it fires and break it leg. I learners that the hard way
RC MAN 23 it also has really bad compression, has some type of knock that will result in catastrophic engine failure, take 10 kicks to start every time, idles high, has a really bad bogging issue probably a dirty carb, semi dry rotted tires, scratched fenders, stained crank case It was also smoking I’m not sure why but still
mm yea I would agree. $1600 was awful cheap for this bike. I would have gotten it, even it needed work. for 1600 you could rebuild this and still make a little money. Nice Bike thou.
You are wrong. You can kick some 4 strokes with the gas open. you can’t kick the motocross bikes because it has a spitter in the carb by the intake tube that spits fuel every time you rev it. Not these but 4 strokes that don’t have the posters you can kick without
Lol NEVER kick over a 4 stroke whilst turning the throttle. If it partially fires it will send the Kickstarter flying forward. Good way to break your leg. Speaking from experience on my WR450 LOL
How do you get bikes for so cheap!? I'm trying to get into the sport and I'm trying to get a yz125 but they all cost like $1700 to like $2600 used on Kijiji..
That 450 needs a lot of work. I have an 04 CRF450R. And it hurts to kick it over motocross boots let alone sandals. In that motor sounds awful has a really bad knock to it. I would say a rebuild job needs to be done..
I like how he says the 'breaks work pretty well' you wanns prey like holy f&ck they do. But don't like how many kick starts it takes to get her going :(
my decked 01 250 would beat my 450 in a race every time, so im not sure what you are talking about, but what else can you expect a 10 y/o to say who cant even sit on a 250 or 450 XDDD
You are so dumb to buy that, the front tire is smaller than the back and it has really bad rod knock , that thing is about to blow😂 you shouldn't be able to kick that thing over like that , no compression and wouldn't start , common sense not to buy that man
COwheelieboy You absolutely do not know what your talking about. Crf450r have automatic compression release cams, which makes them super easy to start. If you don’t know don’t say anything.

Kevin Levick 450s are still hard to kick over with auto decompression
My 05 crf450r has the auto decompress and i still wouldnt dare kick that thing in sandals. Still way too much compression.
The decompression valve definitely doesn't make it "easy" to kick over, that engine seems pretty hashed. There's no way a 120lb kid should be able to kick it over that easy
Disagree. I've had multiple 450s and all of them have been easier to kick over than a 250 2 stroke.
Kevin Levick same!
Your dad looks like he despises RUclips😂😂
Bro was moving his head more than his leg when he tried to kick it over 😂
"Wonder if it has oil" well dont you think u would check that before you buy it
Where is the value in doing that? If it’s empty, it’ll need you to check and fill at home regardless. Stupid comment
Holy crap, that’s a good kick-start for sandals. Mine runs peffect in the winter.
There are no changes in height between a 250, 450 or even a 125. The suspension might differ some.
"Putts around the yard in 2nd gear" (she's a fast one)😂like you didnt even go past 10mph
who ever did the values on that thing did a bad job
Is that why it pops when he revs it up? Or is that normal?
@@Gang162 that is not normal lol its his timing chain slapping
It sounds lean, i would check the valves and compression and do a leak down test, check what jets are in the carb and change the oil.
I'm getting back into racing I don't didn't know what bike I wanted you convinced me I'm getting a Honda crf450, thank you
Bike is running lean, check timing the popping is a sign of lean or timing is off a little. The sound u hear is the chain hitting the chain guide mine does the same thing
Take the kickstart off and move it up a bit so its not hitting the frame. If you didn't already. Great video man.
wow, that property is pretty damn amazing dude.
The kickstart lever needs to be readjusted to it's original position, it's been worked on, it needs to a little more forward, it will vibrate on that twin spar.
Love your vids,man,great family!
I love your vids and I just sub
Rebuild this soon. I personally wouldn't even start it again without a good top and bottom end rebuild. It's been run hard bro...
Year late but I'm gonna say this. It takes about 2 mins for the compression to go away on a crf450

@@Earth11111 Fight me
Bruh it was 1600$ not that much
No wonder there’s bikes building up in there probably all need overhauls
i know that you have owned both but how much harder is it to kick over a 450 compared to a cr125
Kicking and using throttle is a no go. Its not a 2-stroke. Chain is banging to when riding. Hope this bike fits your needs. Good luck with it.
The banging is it tightening

That crf450 seems way too easy to kick over. I had a 2007 Honda crf450 and it nearly ripped a hole through my shoes.
my yz 250 2 stroke rips holes in my shoes your crf could break ur leg lmao i was waiting for the kickback

yupprs
have any of u noticed how small the front wheel is
Landre Porter definately an inch or two too small. Ussully the top of the tire sits above the fork seals. It could also be an optical allusion due to forks being completely draned of oil?
Son that’s fast! First gear around grandmas house!....
ready for you to get a 4 stroke that's not clapped lol
The kids kickin it like a 2 smoke. Pump till firm then send it!
Love the channel. Will bow to your knowledge, but if the owner/seller was not around to answer questions, I'd walk away
thought u didn't like 4 strokes.. but its a honda so it will sell fast
7:22 did he say it's kinda slow if so there is definitely something wrong with it
He Said "It's kinda small"
this is a suggestion everyone should agree with. BEFORE you buy it bike check/drain oil look for the little sparkles
under armour slides with nike socks savage !!!!!!!!

Don't feel bad about the bad purchase . I have been burned too.
Where do you find a crf 450 for 1600 I been looking for a 125 and haven’t found one for under 1500
I just got this 2004 yz250f for 2,400 with new plastics and only 300miles I’m kind of a beginner do any of y’all know if that’s a good price ?
want that 04 to feel like a 2 stroke. get an 04 hrc cam for it. u wont believe how much more power it has and it revs out like a 2 stroke. i owned the 04trx in 04 was first at my desler with hrc equipped. my friend bought 04crf like u have crf had few mph more topspeex but the hrc equipped trx had so much torque was unbeluevable. no other csm ive tried came close
I found a 02 crf 450 for the same price I'm wondering if it's a good deal or not
That's my boy big bikes for days

Clay_Is_28 their not going to rebuild it, they are going to do a top speed run and that piece of shit is going to blow up
that thing should not be that low on compression. my crf250r is harder to kick over than that. I ripped a chunk out of my shoe
seriously 😂
I was waiting for it to kick back
There’s a sight glass on the other side of the case bro.. right under where the oil filter housing is

probably has auto decompression valves and when starting it kick it down a half click then all the way back up then kick through hard should start first kick almost every time.
FACTS.
It has low compression and it has a loud knocking noise probably cam chain that's why it sold for $1600
Nick Doble cam chain need tightening.
@Waylon Wilshire yes
My name is on the boat so can I get like 20% off?
How are they sold but they are still in your garage ? What are they on Layaway or what ?
Damn something is definitely wrong with that bike
Yes, It seems to have 2 extra strokes that need removed.
373Moto Mx Um no. It’s fine other then the lose chain.
It's supposed to be a 2 stroke isn't it? It sounds like a four stroke.
Opferman Motors Dirtbiking good one lol
Alex Gray no
man they treat it so wrong. Never give gas when a 4 stroke is choke on. And a 450 is NEVER easy enough to kick in sandals. Plus something doesnt sound right with that bike. Maybe the Timing?
Jakelols Gaming not just with choke on, never gas a 450 while kicking, it will send the Kickstarter flying forward when it fires and break it leg. I learners that the hard way
Nah timing sounds fine. Seems like his valves are badly out of spec a valve adjustment should rid the compraion
Man when I had a 450 it was super hard to kick over. It had the auto decompessor too. Somethings wrong.
Damn a 450 for 1600. And it was adult owned?? Good deal. Kinda low on the years. But thats still gonna sell for some cash
not with the timing chain hitting the cases its fucked m8
RC MAN 23 it also has really bad compression, has some type of knock that will result in catastrophic engine failure, take 10 kicks to start every time, idles high, has a really bad bogging issue probably a dirty carb, semi dry rotted tires, scratched fenders, stained crank case
It was also smoking I’m not sure why but still
That timing chain is hitting
I feel like a 450 under 3000 is definitely sketchy no matter where you live
mm yea I would agree. $1600 was awful cheap for this bike. I would have gotten it, even it needed work. for 1600 you could rebuild this and still make a little money. Nice Bike thou.
At the time of your comment I could find a handful of 450s for under 3k that were solid. Today you can find one under 3500. Good or bad.
Buddy I got mine for 900 and all that was wrong with it was one tooth off timing. I’m still riding it and this was in 2013. NO REBUILDING NEEDED YET
Never twist the throttle on 4 strokes when kicking them...only twist the throttle kicking on 2 strokes 👍👍
That 450 is ready for blowing thats why the sold it if you can kick a 450 over in flip flops that tells you that its fucked
Luke Fielding so true what an idiot
sounds like something is broken inside the engine
Four stroke you don't twist the throttle when kicking that was probs the problem
You are wrong. You can kick some 4 strokes with the gas open. you can’t kick the motocross bikes because it has a spitter in the carb by the intake tube that spits fuel every time you rev it. Not these but 4 strokes that don’t have the posters you can kick without
Both of you have no idea what the hell you are talking about
It’s knocking. Clapped.
That bike had the living @#$% kicked out of it... How did the bike end up being in the long run?
Sweet bike 👍🏼
Lol NEVER kick over a 4 stroke whilst turning the throttle. If it partially fires it will send the Kickstarter flying forward. Good way to break your leg. Speaking from experience on my WR450 LOL
are you serious bro? thats interesting
that is interesting. I have a 2013 KX450F and I have twisted the throttle just a few times while kick starting it... no problems...
Do i see smoke comong out of the exhaust connection
What kind of exhaust/header is that?
how tall is chuck I'm 5'7 and am looking into buying one would I fit n this bike?
take it to the track!!!!
"Anybody that knows dirtbikes" then he checks the right side of the engine for oil lol
It varies for different manufacturers learn your stuff before you make an insult
Right side is trans oil on these 450s

Michael Molina that bike isn't right, Ik it seems expensive but it's probs worth it to go the extra money.
If you are trying to get in the sport and have never rode a dirtbike I would recommend not to get a 125 2 stroke you need more a begginer bile
valves are probably toast and timing chain is going to snap
And it's going to throw a leg outta bed
It sounds like it’s lacking power, does it not?
I have an 02 model of this bike and it literally ripped a hole in my shoe the compression is so good. This thing is clapped
Chelsea Flanders dude I did literally the same thing with my 02 450, I was wearing foam flip flops though so I wasn’t surprised
1 click after TDC n it will fire right up
You should get a quad sometime and just try it out they are a blast. Preferably trx450r. I'm a honda guy
i think the compression is way too low for 450, you can hear it when its running and he kicked it like some 85 lol
TimiNkoO it has a automatic compression release valve it makes it kick like a 125
Yea you can’t tell by kicking a 4 stroke.
I mean... it may definitely need the valves adjusted
What a stupid comment
"its a fast little guy" 2 seconds later says its slow...."is the rev limiter on there" like its something you just remove...fml these two are clowns
