Did Honda Fix Their Cooling Issues? 2020 CRF450R Coolant Test!

It's no secret that the past few generations of Hondas have had some pretty bad cooling issues...today we're putting the 2020 CRF450R to the test to see if Honda was able to fix those issues on the newest line of race bikes!

This is how many people want a day in the life of Jeff walker 👇

[@lisacollins6430]

You and bridge should set up mics in the van and do podcasts on the way to the track

[@ReturnOfDeeO]

The Honda isn't too hot... but you are. WAIT.

[@CONNORCASSIDYT]

6:48 when you hit that corner😎

[@ZCG616]

I would just install a camel back for the bike to sip on during the moto. A hydrated bike is a fast bike!

[@ReturnOfDeeO]

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.

[@bearmims6717]

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!

[@netz555]

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

[@juanvasquez8446]

Well said buddy🤘

[@zPrideful]

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.

[@thecrazyjuandiego]

I have that issue🤦🏽‍♂️

[@zPrideful]

@@thecrazyjuandiego Considering this bike is 3 years old now i can see why, however it was brand new when i made the comment.

[@thomastjg53]

Me too.

[@justincampbell7800]

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!!

[@gregparker8349]

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!!

[@anthonykrouse7652]

Jesus bro you flying 👌💪👍 much love from south africa 🤙

[@jordymagro7426]

Who wants to see a Jeff walker how to whip video | | 👇🏽

[@maverick2242]

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.

[@paulpreda8842]

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.

[@frankcraymerdds3875]

The hoses that are 2 piece, get a Y silicone 1 piece. It can constrict flow.

[@Hanibul_Lecktor]

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

[@idrissalam]

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

[@shaner3727]

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!

[@dustin9035]

I think your exhaust mechanic needs to be on camera attending to the radiator.

[@chadsugden411]

the old honda mapping was quite lean i feel there new maps have more fuel in them so it makes the bike run cooler.

[@stevenkilleen8149]

Did u try changing rad cap make it hold lil more pressure

[@racerdude23]

I'm not a fan of doing the Rad Cap. Cause it's only putting more unnecessary pressure on the water pump

[@stevenkilleen8149]

@@racerdude23 I work own radiator repair shop yes def only want to go up small amount .1 but gotta get a temp first off

[@jeffgilman4901]

I still say,Jeff is going to be riding for a team if not fully backed,then partially backed by Michael Lindsay👍🏼👍🏼

[@CarsnStuff]

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.

[@phillipwagner7347]

Keep up the awesome videos jwalk!

[@lipingsometoadstv7429]

If you have to use Evans liquid coolant will not boil over! But you don’t add water

[@79brumley]

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!

[@Motoinc]

Just put a Trailtech fan And NEVER worried again You need the one that draws the air NOT blowing the air.

[@rickgaylor3122]

@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

[@mtbridingog9083]

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 ..

[@The-mz2pq]

2.0 radiator cap and it won’t puke anything. 1.1 isn’t enough and they wear out

[@MichaelLindsay]

The 438 2.0 is hard on the water pump seals.

[@The-mz2pq]

Michael Lindsay kawi runs a 1.8. Ran 205 hours on my 2017rx with a 2.0 and never had a issue

[@jmcmotorsportsracing4059]

Looking solid out there💪

[@DADSGETNDOWN]

Does the coolant just dissipate, evaporate or what ? Mine Never loses any, although completely different year, bike and riding. Although still a Honda.

[@eric6rock]

Bike couldn't cool down, kit was too lit 🔥🔥🔥

[@fastfisky9075]

Of you get a high pressure radiator cap and evens waterless coolant. But you have to use the prep fluid first

[@arturcuryllo5832]

Obviously super stoked!

[@bencote2219]

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!

[@Andrewrod25]

Benjamin Cote I don’t think it was that cause the regular 2019 crf450r had the same problem

[@chazzgonzalez1356]

I heard engine ice actually runs hotter. I use Twin Airs coolant and my bike runs noticeably cooler/better.

[@keaganpergar5500]

Which fuel do you use for your crf 450?

[@jaisontompkins596]

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

[@Blueovalnation]

Should see about getting that tusk rad cap so you can see about what temp your coolant is.

[@tundraguy9612]

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

[@joewood7761]

Straight rippin’ dude

[@mike619madman]

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!!!

[@JeffWalker84]

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

[@mike619madman]

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!

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.
