very nice as usual. Wish you the best success in your business !

[@3SeasRecreation]

Thank you very much! Enjoy the ride, Jared

[@thehungryhunter3454]

So I have about 7hrs on the upgrade kit and it's leaking. I bought another one from Beta hopefully it was just weird fluke and it doesn't happen again. Love your vids keep it up!

[@3SeasRecreation]

Hey thanks for watching! Keep in mind we offer discounts on all of those parts you buy from the Beta website! Give us a call and we can help! [phone]. Yes I would assume a bad seal or possibly some dirt got in at the wrong time. Enjoy the ride, Jared

[@ow-my-achilles1106]

You're not alone. I've tried several times with new countershaft seals to get this kit to work. I even have a tool for making the seal absolutely flush and not pressed into the case too far. But a .045 inch gap exists behind the bushing and seal surface each time. The bush cannot press further onto the shaft because the O-ring in back stops it. It seems like the counter shaft seal must sit proud of the case instead. It's what I'm trying next. But removing the seal ruins it each time... Trying to find just the seals.

[@thehungryhunter3454]

@@ow-my-achilles1106 Yeah they don't have a number on the seal so I gave up trying to figure out which one it is let me know if figure it out thank you.

[@adibabi]

Are they roller bearings on the output shaft bearing on these bikes ?

[@danekline7913]

I have a 2018 beta xtrainer that I’m constantly having to replace the countershaft oring. I tried a thicker oring but it still leaks after a few rides. Will this upgrade help fix that?

[@chadrides914]

I’ve got a 24’ Beta Race 300. I’ve spent over 200$ in countershaft seals in 60 hours of owning it. This is getting ridiculous. Seal replacements fail within an hour of the first ride after replacement. I’ve tried new front sprockets and tried seating the seal in different depths. Nothing stops it from leaking. Any tips? I had a yz250 for 400 hours and the countershaft seals lasted about 40 / 50 hrs before leaking. What’s up with this beta seal lasting about 30 minutes?

[@streakfighter]

Very helpful as always, your channel has been an invaluable resource since getting into a new 2024 beta 430 race! Thank you for all the great videos and keep up the good work!

[@jackmilan74]

Hi Jared, thanks for your videos! i have tried to locate the Beta kit AB-50105 over here in Italy but appartently it is not available. I wonder if you can share instead the P/N of the new bushing. Take care! Giovanni

[@3SeasRecreation]

Good Morning, thanks for checking out our videos! The next time I get a kit in I will see if there is a part number on the actual spacer that I can provide to you. Enjoy the ride, Jared

[@mattkreese]

Any video for 2023 beta 300rr!?

[@3SeasRecreation]

This would be the exact same process other than removing the countershaft sprocket.

[@blindshot709]

I've got a CRF250r 2006 and it's leaking alittle oil over the front sprocket , I ordered the counter shaft seal but should I get the spacer sleeve and O-ring as well to do it all or should just the seal be fine ? This is my first bike and Honda won't sell the kit for it, So I needed to Know each part to get it OEM .

[@PacificArc]

2024 300RR, I installed the seal flush, then slipped on the oring, and when I put in the spacer it was hard to fit all the way against the seal. I tapped it a little but didn't move much, so I stopped concerned something was not correct. Should I continue to tap till it goes all the way against the seal?

[@3SeasRecreation]

Hmm, I usually use some grease to help the spacer slide inside of the outer countershaft seal. Other than that they should fit pretty easily.. Not sure the issue there, maybe have a friend with another point of view have a look, sometimes that helps! Enjoy The Ride, Jared

[@PacificArc]

@@3SeasRecreation thanks

[@robertthurman3743]

Is this an upgrade for older bikes at the appropriate service interval or does this come on the new models?

[@3SeasRecreation]

Good Evening, this is an upgraded kit that does not come stock even on the 2022 models. It is something that I would recommend doing after a few seasons, maybe after your 2nd front sprocket or so. It seems the stock collars get some wear and this is an inexpensive and easy to install kit. Thanks for watching! If you ever need beta parts consider giving us a call I would be glad to help! Thanks, Jared

Hi, great videos. I have the 390. Do you ship to the UK? Thanks

[@3SeasRecreation]

Thanks for watching our videos! I do not ship out of the country, still not sure how all of that works. Maybe in the future I will have a better handle on that but for now we are only able to sell and ship within the US. Thanks, Jared

[@selophane43]

Great video. So here’s my question. I have an 18 X trainer and it seems like I have to replace this countershaft seal every 500 miles which is dog crap. As far as I know I’m installing it correctly but I was wondering which part actually stops the oil? Is it the O-ring or is it the actual seal? I read somewhere that if there’s still a leak I could go with a fatter O-ring. What do you think?

[@3SeasRecreation]

Good Morning! Thanks for the comment, my suggestion would be to make sure the countershaft itself is not scraped or nicked which could be prematurely wearing out the seal. Have you tried this upgraded seal kit? If you live within the USA we can offer drop shipping right from Beta on parts/ accessories and DISCOUNTS as well! Feel free to reach out with questions! Thanks, Jared

[@selophane43]

@@3SeasRecreation so what I found out is that I’m installing the seal too deep into the engine casing and not leaving it flush with the outside. The little lip on the spacer is not seated in between the lips of the seal. I wish I knew that along time ago. Thanks for replying. Peace.

[@reknelb]

@@selophane43 I did a new seal kit, lasted one ride. Used a fatter o-ring, no more leaks.

Thanks for the comment, good question. Nope you can do this without draining the oil. Thanks, Jared

[@WillyD1]

Did you like the 300 rx motor or the new 300 rr race edition motor better

[@3SeasRecreation]

In the woods that we have here in WNY I enjoy the standard RR engine, if we were down south in the sand or the elevation out west I would enjoy the RX engine. If we are riding motocross I enjoy the RX for sure and we do ride that quite often. It's really a toss up, you can make both bikes work good for you it's just trying to find one! Thanks, Jared

[@Sean85Laney]

what kind of loctite do you use? what kind of torque wrench do you have?

[@3SeasRecreation]

I would recommend using the blue loctite, the red is way to strong and makes it hard to come out. As far as torque wrench, I would just pick up a reliable brand that works for the range you need.

[@jamesking4225]

I’m wondering what that miracle paste is lol all of my thread lockers are runny . that looked thick

Hey do you have a part number for the Mac tool you used? I tried to find it on the tool truck today 😅
