You passed me out there like I was standing still

[@jestonsendsit]

That looks a lot faster than a couple of 10ths, I’d say a couple of seconds compared to your last videos on this track. You look incredible dude 😮

[@theread3480]

I’m not sure how much work Jerry Robin has done to his engine but I’m going to guess it was not stock. That was something that was really noticeable in the comparison video at Glen Helen. Not only were his lines better but his bike just looked like it had way more get up. His bike on the camera just looked like it exploded forward any time he got into the power. Your bike did not look like that. This is a sand track so it’s not super comparable to glen Helen but I can definitely notice more of that “explosive” power Jerry’s bike had in this video.

[@ghpjerry]

Jerry just needs to learn to stay on top of the bike rather than underneath hit. lol

1 Month ago best lap time 1.53.14 Now 1.51.00 Great stuff brother, can definitely see a difference now through the thick sandy corners, shes moving out of there a lot easier and youre floating on the straights. 💪💪💪 cant wait to see the motos as well.

[@JeffWalker84]

Glad to see the lap times are confirming how I feel on the bike! Thanks brother

[@rndmavis]

Your lean angles are sick this session

[@bmecham9017]

Holy cow Jeff! I feel like I am watching this at 1.5x! The obstacles are coming so much quicker. You are flying! So excited for you (and us to watch you).

Holy fast!!! Can’t wait to see you in those motos!!!!

[@markmontgomery2562]

Good deal. Go get it. Always love it when somebody is tracking backwards @ 1.54

[@tysimon]

That's some serious power and readiness, rev range also improved on top end.

You rode the rubber off the bike on this day Walk!! I noticed the difference right away.. Did you edit this in 1.25? Lol j/k.... go get em!

6:05 nice switch to the inside line, that was smooth 👍🏼👏🏻 engine went up to high rpms without any doubt ✅

[@grahamhenry3436]

I can see a lot of improvement on the mod engine compared to stock can’t wait to see you in the top 20s your ripping dude!!! Are you going to buds creek?

[@jedielder7970]

So when you say engine rebuild, from what I could hear you say in the video, you mean a top end job, right? I know factory teams also do a lot to the bottom end of the engines (transmission, crank, bearings, etc.) Can you give more, specific details, if possible. I find all of this stuff fascinating. You do look really fast on your bike! Thanks for the great videos.

[@AntoineCS2]

seing Jeff, wanting a 450, thinking about my skills and performance, look back to my 250SR and let it in the garage 😂 nice ride buddy

[@JeffWalker84]

Take a spin on a 350 sometime! I think that's the perfect bike for most people

[@Multigamer9555]

Your speed on this track is insane dude!

[@jaredboshaw]

Always nice seeing you out and flying pass me. 🤙🏻🤙🏻

[@mikeburnett6222]

It's hard to tell if the bike is any faster via video. But th sound of the motor definately has NO soft spots or points where its lunging down. You'll definately qualify better with this engine! I raely want to see how much better your time are going to be. Congrats

[@Kiddsworld66]

I swear Jeff just keeps getting faster and faster! Didn’t know he went to gas gas, last I saw was KTM after Honda

[@ElNitro7]

Bro you are flying! I had a question for you pertaining to upgrades. I'm on a crf 450r (2024), was looking at new exhaust, any recommendations?

You are really flowing well! That engine sounds alot tighter and fresh. Top end power band increase is noticable. Have you considered refreshing your breaks for the added power?

My god man that was insane. Honestly I feel like now the bike just matches your capability speed wise

[@1993YZ]

You really surfed the track today! Less attack mode. More vibe out there today. It looked faster.

[@ReklessStandard]

Having an upgraded engine will very much do you wonders. Especually with having that upgraded ECU. And im sure this gave you a huge confident boost because now you actually have some power to work with. Im curious for the race

[@Randy_Cox]

I can't imagine riding a 450 and thinking....it needs more power.😂😂 I have my kx450x down tuned from stock to make it easier to ride and not die. Your straight rippin dude.🔥🔥 Go gettem.

[@swedish_sadhguru3854]

why would you downtune it instead of riding a 250?

[@Randy_Cox]

@@swedish_sadhguru3854 because I already have a 250 and it isn't detuned to 250 power levels....more like 400 power level. To be honest it is only tuned down below 50% throttle and below 7,000 rpm. Once you twist more than 50% or revvover 7,000 it goes straight back to full power. Makes tight trees, roots and rocks much easier to get through.

[@swedish_sadhguru3854]

@@Randy_Cox I see, interesting setup!

[@brantleyanderson3427]

Genuine question and not trying to start an argument, just curious. Why a 450 over a 2 stroke woods bike? I had a 21 450x and I hated it in the woods and got a husky 300 after about 6 months. If you do well on it more power to ya! Just was too much of a battle for me compared to my 2 stroke

[@Randy_Cox]

@brantleyanderson3427 Mainly because I am 6'2" 270lbs and having a bike with enough stank to move me around is awesome. My KX250x is setup on race gas, exhaust and it still bogs and is slow to rev with me on it. The 450, detuned with pump gas will wheelie over.🤣 And I like challenges.

[@mav459]

That corner with the 3 rollers through the inside after the double into the corner and that hip roller needs to be looked at differently. I know it's easier said than done, but you need to figure out how to double that. That is the shit I am seeing all these top guys doing. Playing with the track. Hippin and hoppin. Have some fun. Flow with it instead of banging your way through. Just an opinion, of course, but you could gain at least a second a lap doubling one of them instead of rolling all 3.

Bike sounds sick dude.. Not been out to SC. looks cool, usually down the road. Question. They ride by class or is it a free for all? Kinda looks like the latter..

It's all free ride. Good for doing long motos, but you're definitely out there with a variety of riders...best to show up late while the majority of the crowd is heading home

Throw some ceramic bearings in those wheels, motors are cool, but you need to free up the friction.

[@JeffWalker84]

Interesting suggestion. What company makes them? I'd love to try some

[@dandlugolecki3408]

@@JeffWalker84 our distributor is “World Wide Bearings” out of NJ. He’s made all of the ceramic bearings for Stew, Carmichael, Reed, everybody. It’s honestly pretty stupid the difference. You’ll gain 15% power, and make your suspension work better. Doesn’t dig and sink into the dirt and sand so much, glides and floats easier. Friction is the enemy.

Jeff, being a taller rider, do you prefer the ktm/gasgas chassis because of the room you have on it? I'm shopping around and the ktm seemed to feel pretty roomy just from sitting on it in showroom. I'm 6'6"

[@JeffWalker84]

It's definitely one of the roomier cockpits, but you can make any bike fit any size rider with some fine tuning. I just like the feel of the austrian chassis and how smooth the power delivery is. Plus, they're nearly indestructible

[@AntDePietto51]

@JeffWalker84 I usually run tall bars and stuff like that. I'm on a 17 honda right now and enjoy it. I'm thinking a KTM or gasgas 2 stroke is in my future

more air in, more air out. more air means more fuel means bigger boom. bigger boom means more power. plus the added compression, youre squeezing that boom even tighter making even more power.
