You should do vlog “teaching Bridget how to ride a dirt bike”

[@ReturnOfDeeO]

Anytime I see this type of comment, I think to myself, does Bridgette WANT to learn to ride a dirtbike? Does she WANT to show her progress to 100K+ subs? Gotta think just because you want to see it, doesn't mean she wants to do a video like that.

[@gmoney505]

@@gmoney505 I'm so calm. :)

[@williamgalloway4798]

plot twist, Jeff isn’t the rider, Bridget is😂

[@ruo7727]

I’m so ready to see that 250 shred glad your lurking the j walk workshop 🤙🏼 hope you staying safe bro

[@allied.1296]

Motion pro coolant recovery tank helps as well, I race trails and had the struggle of over heating in any type of wet conditions or sand. Haven’t had to refill in a very long time, it basically recycles the coolant besides it all spewing out it’s about $20 worth a shot definitely.

[@green2153]

I’m so tired of this quarantine, your so lucky you get to ride. Keep up the good work

[@motoxarmy7877]

Jeff, have you tried upgrading your radiator cap to 1.8? Also try Evans coolant and see if that helps. Great vid. Keep doing great stuff 👍

[@frankcraymerdds3875]

Boyesen SC really helped my CRF, plus Y shaped silicone hoses.

[@troyhubbard50]

Try an OEM KTM radiator cap. It’s a 1.8 versus the stock Honda 1.1. No issues with my 2017 out here in hot so cal

[@ReturnOfDeeO]

Yessss The Return of Bridgette! The Yoshis barking and echoing through the woods is so sick, sounds so good. Yessss a squid squad moment! Glad you got the supercooler and it's working so well for you. I don't think I ride long enough or hard enough to need one right now. But on my next bike maybe it'll be my second upgrade (1st is going to be Race Tech Suspension. After doing it to my Honda I'm never going back).

[@Hot_Brass_Media]

New bike?!?

[@robbietucker7815]

Fire content bro! This is why I stick around this channel

[@jeremykeech63]

Yup same

[@brianthomaskelly5074]

I’m so glad you keep posting about this issue. I bought a 2020 CRF450RWE in April and was totally fine until the 8hr mark. Then the cooling issues got worse and worse. I had it in the shop multiple times trying to chase this problem but they couldn’t find anything wrong. It pissed me off too because I had videos of being at the track just warming up the bike and coolant spewing out the discharge hose. Def going to look into the Boyesen power flow water pump. I did a 2007 CRF450R build with same pump and oversized radiators and never had any issues even when slow trail riding. But I also was using Evens Waterless Coolant.

[@DADSGETNDOWN]

Not sick of your "mug", but definitely nice to see Bridge, she looks like she is doing well.

[@jeremiahsamuels9312]

Notification Gang WYA!!!! Love your vids Jeff

[@pags1981]

Hi Jeff, I'd recommend a Precision Engineering steering damper. Has independent high and low speed damping (Barcia is using it). This in combination with a Magura hydralic clutch = saved energy and harder riding for longer :)

[@iloveyoualot4237]

Got the notification late, thanks for another vid!

[@reelphatties6426]

Hey bro a little secret if you plan on racing washougal national stop by tnmx at PIR on Thursday night and race the pro race first place is normally a 3k pay out

[@caseymineo4880]

Hey jeff is just like to say that your vids are the best, never change them up and you have helped me become a lot more confident on the bike and the track, keep it up, i’m sure a lot of other people are helped by you!

[@amacoutdoors2076]

I see a lot of comments about getting a better radiator cap. Yes they help keep coolant in which will help it run cooler eventually, but if your bike is losing coolant or would boil out with the normal cap on, it is already running too hot and this will effect performance and longevity of the engine's parts and components. Getting this supercooler is way better for the bike than just a cap. Combining the two I am sure would only help but if your having overheating throwing a different cap on is only a bandaid. Getting a better water pump is the way to go

[@jimbo4298]

You're on the gas to much bro!! Welcome back Bridge!! 👊👊✊✊✊

Last thing! Open practice this weekend Sat! And Sunday! Come out

[@garyhenke806]

Hey J Walk, I put several of these on my hondas in the past. Most notable was on my woods bike CRF250X 2004. Yes it is that old but runs like a champ. Overheated in one harescramble and put the supercooler on. END of problem. I agree that should be a first upgrade. Doen't appear that different than stock, but it moves more coolant!

[@garyhenke806]

And also, the other guys who have changed radiator caps, I agree as well this makes a big improvement .

[@zayuh2313]

Yea have def missed bridge and been wonderin where she’s been. Love to both of y’all. Can’t wait for SALT LAKE!!!!!!!!!!!!!! So glad it’s finally startin back up. Moto season is right around the corner

[@Rpnpap44]

I have a 2015 Yamahayz450f that i ride in the desert and in the hills and at the track and it used to go through alot of radiator fluid in the hills going through rock gardens and on single track trails. I got a Boysen supercooler a high pressure rediator cap with temperature guage and changed to engine ice and have not had any more issues. 👍

[@AntonBerlin]

I was like wtf is that snow!?! We don’t even have that in sweden anymore😂

[@YZFMX256]

Glad i found this video bc my 17 450 drinks coolant like no other. If i did a full weekend of riding (Saturday practice and Sunday racing) i would go thru almost a whole bottle of the Honda coolant.

[@Rubbinz24]

PC is selling those catch can's now too, but I believe they're only for the Kawi's. "Cool" system though. Along with new hose's, a high pressure cap (85cc 2$moke cap works best) and new supercooler, JWalk... you'd be set. 2 $moke video next please. 😂🙏

[@davegolsteijn3588]

Had one on my 2009 honda crf250

[@justinmoto929]

They are universal

[@venton3]

I have that water pump on my KX450F. I also was constantly having to top off the radiator. It definitely helped

[@tencentsboys2791]

JEFFFFF YOUR THE BEST!!!!!!

[@stuckcamping]

Pretty sunny in the garage today

[@pbanthonyv]

The bane of my CRF250 was clutches and valves. You pretty much had to do both to get in a half decent season of weekend warrior woods riding. The basket would go in about two seasons as well. Switched to a WR250 (YZ with soft forks and lights) and I'm two and a half seasons in with only a new set of springs in the clutch and no valve movement.

[@matthetherington4171]

Have you tried a higher pressure cap? That may keep it going down at all. Keep up the great work.

[@834honda]

Get a 1.8 Barr radiator cap. The 1.1 is a joke.

[@Dirtbiker4541]

Can you explain what a cap does to actually make a difference? I’ve always wondered..

[@turtleface166]

@@Dirtbiker4541 holds higher pressure which increases the boiling point of the coolant. once your coolant is boiling, it won't cool anything anymore.

[@jaydensdream714]

@@Dirtbiker4541 and ktm when it boils over it normally spews out to a certain degree. Requiring you to refill it. My cr125r will spew some when filled but cools fine just below the fins.

[@MotoBuilds]

It will keep it from boiling over but actually allows your engine to get a few degrees hotter, so the benifit is negated.

[@fryerMC]

Wouldn't that increase a the risk of blowing a head gasket due to the pressure?

[@cantthinkanameup]

Jwalk buddy you should try a high pressure radiator cap. That 1.1 isnt helping. A high pressure radiator cap will allow more pressure inside your cooling system which will keep from boiling over and spewing out the overflow. Seriously, put a 2.0 bar cap on there and your coolant issues will be a thing of the past. My 18 250sxf came stock with a 1.8 bar for comparison. Im also running a boyesen super cooler and they definitely do work.

[@jacobpressley4449]

I would try a cooling fan on the radiators as well. It probably would help even more! Just a thought for future reference.

[@MikeyH18]

Yoo! That FXR gear looks sick! Shame they don't have an official UK store.

[@harpermx2962]

Hey Jeff Ik ur a pro and all but maybe try slowing down ur entry speed just a little like 5 mph then get on earlier then you’ll make less mistakes and you’ll have faster lap times this helped me out a lot but great riding u looked good out there

[@ReturnOfDeeO]

lol

[@lukebrown8117]

1.8 or 2.0 bar rad cap 👍

[@sadboisonly1004]

I'd also reccomend upgrading to a higher pressure radiator cap and maybe some new radiator hoses for better flow. The more the better 👌

[@Rubbinz24]

Exactly! I believe guys are getting those caps off 2$moke 80's, but I could be wrong...

[@sadboisonly1004]

@@sadboisonly1004 I know that and I'm sure he'll eventually upgrade his hose's and cap eventually. But I did see some pro's running caps meant for 80's because of the high pressure #. That with the supercooler and a catch can system and you'll never have cooling issues again.

[@hargett3129]

Try some CV4 hoses along with the Super Cooler and Engine Ice. Made a lot of difference in my CRF450R. I could be wrong but I think the CV4 hoses are a touch bigger internally as well as allows the coolant to flow a little more freely.
