You and bridge should set up mics in the van and do podcasts on the way to the track
This is how many people want a day in the life of Jeff walker

Engine ice is for sure great when you want to exchange heat faster and better than 50/50 mix but you will also have more of a risk to boilover and loss of coolant.
Evans waterless doesn't boil so it stays in the machine and you will have less chance of ping when running hot BUT it will not solve an overheating problem.
The key is to get the hot coolant as fast as possible from the motor to the radiators and have a really good heat-exchange then get that fluid back in the engine.
In the world of hopes and dreams, it would be awesome to have the heat exchange of engine ice and the boil point of evans coolant. Sadly the reality we live in does not allow this.
So on the short fast version of this.
Better/faster heat exchange = engine ice
Higher boiling point: Evans coolant.
More coolant flow/speed : Boyesen supercooler
More fluid displacement: Aftermarket head and radiators
Well said buddy🤘
The Honda isn't too hot... but you are.
WAIT.
I would just install a camel back for the bike to sip on during the moto. A hydrated bike is a fast bike!
6:48 when you hit that corner😎
I run oversized Fluidyne radiators they are great -thick, strong with tig welds and of course they hold more coolant capacity. My bike is fully modded but never overheats and I was doing tight slow technical single track in 95*+ temps. That new Honda you got is a hell of bit of kit!! Would hate to see it getting hot!!
You're literally the only person ive ever heard and can find anywhere that had an issur with coolant dumping out of their 2019 honda 450 to that extent.
I have that issue🤦🏽♂️
@@thecrazyjuandiego Considering this bike is 3 years old now i can see why, however it was brand new when i made the comment.
Me too.
First
Go JWalk!!!
Yo man big fan of you Jeff you’ve really been cool to watch and learn some technique from!! Big inspiration!!
Also good third person footage from Bridgett!!
Jesus bro you flying 👌💪👍 much love from south africa 🤙
I didn't know the Honda made the most power, I always thought the Yami had it covered!
Off topic of this video, but is the top clamp back to stock helping? (I comment while watching, and you just said you'll have a new video of that so nevermind).
The windscreen will be so nice. Wind noise is just so frustrating, nothing you can do about it after it's too late.
3:57 - Blowing out berms? Who are you, me? 😂
Being in Colorado, I really don't deal with the heat like Florida, and/or I'm just not riding as hard as you, obviously. What does the bike start to do when losing coolant? In an older video I remember you pulling off the track and saying the bike was overheating. What are the symptoms of an overheating bike?
Rippin' out there though brotha. I've always felt the aggressive map is overkill, even for my '17. Because it doesn't give you MORE power, just a harder hit on the power and harder to control. I think it was something Kris Keefer said. But since then I also got my ECU remapped to be more manageable.
Thanks for the footy, Bridgett.
youre bike will start smoking haha, it just dumps out coolant, you might feel it or see it but as far as i can tell there isn't a feel different when it starts to overheat.
Love your work DeeO!
The hoses that are 2 piece, get a Y silicone 1 piece. It can constrict flow.
You may try the ims motorcycle coolant recovery tank. It looks to help some guys in enduro, you won't loose your coolant from what they say
sand guys know about clogged fuel filters, and lean issues. Alcohol based coolants will only shut off the problem but not fix-it. check your mapping and go rich, especialy in the sand. It worked for me still race that ol honda on the same top end after 200hours.
Good video Jeff.
Have you tried silicone hoses, maybe get CV4 / Samco on onboard, will help with heat soak and run the bike cooler. Cooler is always more power and more reliability too eh.
Back in 2003 for Baja we ran a im frame coolany reservoir because feep sand and the heat would make them puke coolant. 100% fixed that issue. With the 2019 I bet it was a mapping issue. I don't see significant changes in the 2020 motors
the old honda mapping was quite lean i feel there new maps have more fuel in them so it makes the bike run cooler.
Id say if you have coolant issues get upgraded radiators. i know some people dont like the thicker ones cuz they can sometimes widen the shrouds a bit. But i had overheating problems on an older crf i had and upgraded radiators and never once had issues with it after. Thing was reliable and lasted years with out over heating.
I was considering it for my newer bike but its the 16 and its never had over heating issues so far. But then again i dont ride super hard like i used to on my older bike.
@jeffwalker i had the same problem from stock but a good upgrade is try running evans coolant i race 2019 crf 450r and i have never had issues with sand getting in the rads and it over heating it doesnt boil over and doesnt freeze it froks awesome
Stock triple clamp, bars in forward mounting holes, 5mm off set... how much of a pain to adjust clickers? Don’t the bars sit directly over clicker adjustment?? Ps thanks for the 20% off!
Of you get a high pressure radiator cap and evens waterless coolant. But you have to use the prep fluid first
Did u try changing rad cap make it hold lil more pressure
I'm not a fan of doing the Rad Cap. Cause it's only putting more unnecessary pressure on the water pump
@@racerdude23 I work own radiator repair shop yes def only want to go up small amount .1 but gotta get a temp first off
If you have to use Evans liquid coolant will not boil over! But you don’t add water
That's a bad thing, If you're engine is getting hot enough to boil over regular coolant you want to know about it and coolant coming out of the overflow tube is the way to find out!
I still say,Jeff is going to be riding for a team if not fully backed,then partially backed by Michael Lindsay👍🏼👍🏼
Obviously super stoked!
Ive had similar issues with my 2020 kawi 450 went to engine ice and the problem went away highly recommend engine ice for anybody who track races
Just put a Trailtech fan
And NEVER worried again
You need the one that draws the air NOT blowing the air.
Does the coolant just dissipate, evaporate or what ? Mine Never loses any, although completely different year, bike and riding. Although still a Honda.
I heard engine ice actually runs hotter. I use Twin Airs coolant and my bike runs noticeably cooler/better.
Taylor Anderson 😂💀
I have the 19 Honda 450 works edition, and i did a 1.5 hr woods race on it and i never have any problems with the coolant going low
I think your exhaust mechanic needs to be on camera attending to the radiator.
Who wants to see a Jeff walker how to whip video

👇🏽
2.0 radiator cap and it won’t puke anything. 1.1 isn’t enough and they wear out
The 438 2.0 is hard on the water pump seals.
Michael Lindsay kawi runs a 1.8. Ran 205 hours on my 2017rx with a 2.0 and never had a issue
Had the same problem with 250. I just put a 1.6lb rad cap on it and solved the problem
Norman Peterson where u get that cap at?
I believe you can get them at any bike shop
Should see about getting that tusk rad cap so you can see about what temp your coolant is.
Keep up the awesome videos jwalk!
Bike couldn't cool down, kit was too lit 🔥🔥🔥
It's not a Honda issue it's a coolant issue g .. the coolant that you use in the bike plays a big part in it overheating .. the coolant shouldn't come out of the overflow hose when being ridden or at idle for a few secs ..if it does then the cylinder head is either warped or the head gasket is blown ... Or the coolant has a low temperature point ..
My 03 did that. Fill only to top of fins. She needs room to expand.
Looking solid out there💪
Jeff did you consider that your 2019 was a WE and your 2020 is not? I think the porting and other mods they do to the WE engine have a lot to do with the running temperatures. Maybe your pal MLindsay can comment on that? I've never had issues with my 2019 non-WE 450R, granted I ride in the northeast and not nearly as hard as you do!
Benjamin Cote I don’t think it was that cause the regular 2019 crf450r had the same problem
Well it is handy to have a couple bottles in the van just in case.
Straight rippin’ dude
I want to buy a 2020,crf450 but I’m scared of this issue,how do you solve it
Which fuel do you use for your crf 450?
Kind of curious if anyone knows, but what brings Jeff back to this track so often? Is it just the most convenient or is this one of his favorites? Idk if i've missed it from any of his other videos or if he's talked about it yet. Either way, keep up the good work Jwalk!!!
This track is only 40 minutes from my school. The next closest track is 2 hours. I try to make it to other places when I can but it’s hard to make the journey when I have so much to do at school
Jeff Walker alright, was just curious. It looks like a super fun track and you ride it out of your mind. Content is content and I’ll watch it either way, keep killing it man! Can’t wait to see what you get up to next motocross season man!
Need to put some Evans in there and you wouldn’t have to worry about any overheating!
D I water and redline wet wetter
Killin It in the sand🤤
What Garmin do you have?
My 2024 CRF 450 works edition overheated when I was warming it up and coolant leaked out. Does it hurt it when it overheats like that
Was wondering why your not practicing super cross for straight rhythm coming up in two week? Just don't want to see ya weeded cause the track is gnarly this year.
Try using the regular green hp pro-Honda antifreeze, in blue bottle. Might run cooler
High pressure cap will fix it I had the same problem w my 17
Ryan Mudge which one did u get
Have you tried a 1.8 radiator cap?
Noticed you had the ride engineering lower clamps but factory uppers? Having bar mounting issues or some other issues?
seriously thinking about getting a 2020 crf250r in a 250B rider & would be racing my area qualifiers & try to go to regionals & then lorettas, never rode a honda but i’m really wanting one should i go with honda?
My engine boils a lot and drains the water from the radiator very quickly. How can I solve my problem?
Crf450r 2010?
Hey Jeff unrelated comment but what tires do you use on your 250, I wanna go out to 74mx but dont know any good sand tires that the locals use
I see you holding the camera and driving bro. #Sketch
A MOTO ESTA MUITO TOP, SO FALTOU TIRAR ESSES PROTETORES DO GUIDÃO PRA FICAR MAS BONITA
Fix it with a boyesen supercooled water pump.
Jeff why you don't race in mxgp, mx2 or mx125
You should try Evans Coolant, bike runs much cooler
I just had my crf450R 2017 idling for 10 mins and it dumped little coolant out the over flow pipe I believe so this is normal ? 😲
I thought the husky/ ktm 450 had the best power plant?
Could you do a review of the knee braces you like most? Been looking but can’t commit yet
Cody Cadwallader pod knee braces are really good
Cody Cadwallader I run mobius and I couldn’t of made a better decision I liked the alpinestar ones but I didn’t feel like there was enough to them I just feel safer in my mobius ones
Cody Cadwallader I’ll second for the pods I have k8s and they are unreal also can remove the patella protection so the braces are multi use eg wakeboarding snowboarding etc
What is this track? Just came back from flordia and couldn't hardly find any tracks to ride during the week.
I know you ride in the sand a lot, what do you do to keep your fork seals not leaking and working good?
Is it true ur gonna be riding for JMC?!
Torqued Af nope
Michael Lindsay I feel like that’s what you would say if he was tho
@@lisacollins6430 he should be riding for someone...teach him to get mean, no friends on the track! He could do something given a shot!
It’s likely ML has a package thing for next season, Jeff will reveal when he’s ready, he wouldn’t have brought a 2020 Honda and sold his Factory Husky etd 19.5 if he was going to JMC.
I wish he’d given the 19.5 fact ed a chance with a tuned suspension package this season though he did dam well on that bike stock, but he’s staying with red, heart wants what the heart wants plus if that’s where the deal is best as a pro you have to do the best thing for your career.
Maverick224 JMC also sells Honda so he could race a Honda and still ride for JMC
So JWalk I was thinking what are you gonna do with the channel if you get hurt and can’t ride?
Run Evans coolant
I think the 19 might be a lemon. I have a ktm and it recently started hating coolant, she overheats in the first 10 minutes of a moto, im struggling to figure out why
Either head is warped or head gasket is out .. or the coolant has a lowered temperature point ..
Did the Honda 250 have the same issue
How many Hours do you ride on the bike per week?
This man rips on every bike 250f 125 450 250 2 stroke he'll probably even rip on a 85 2 stroke
Ok honest answers only no wanna be know it alls please. Does engine ice really make a difference compared to regular coolant??
Maybe we should make a video about it!
Song in the start of the vid?
how do you not get bad arm pump? I . cant ride longer than 10 min without it affecting my riding. any tips??
Luke Downey keep riding
Get a high pressure cap
Hey jeff the 19 full yosh fits on the 20 right
That's what i've heard, but I haven't actually tested it so I can't say 100% for sure
Thanks dude
What watch do you use?
Out of curiosity, what that watch on your arm called?
Garmin 735xt
what watch is that?
This is why u buy a ktm or a husgy. They are proper built machines with care not jus Robots putting bits together
1 BR a dar like up up up
You need to get a crf110 for bridge so she doesn’t have to walk to get film
That is not deep sand
What suspension are you going to run?
Racetech!
What kind of chest protector do you wear
Alpinestars A1
Why do u practice on a 450 but race a 250?
probably maintenance reasons.
Yooo!!! MX factory wants to race u!! Hit him up bet he’ll win😂🤔
Tell him Hangtown is May 16th! Come line up!😜
How come it is not a know problem? I think you might be doing something wrong...
It's a VERY well known problem! Almost everyone I know who rides a 17+ crf has some kind of coolant loss after each session
Jeff Walker how much coolant is lost? Are they seizing? I’ve never heard of this issue.
Honda you should change your name and stop living under a rock!
Bryan Wonders why would I change my name lol, and I don’t live under a rock.I’ve just never heard of a Honda mx bike having cooling issues, just Jeff’s.
