Hey Yama-Haulin! Thanks! And, honestly, if it was me, I would just buy a new transmission! They are so cheap. Unless you just enjoy taking things apart to learn.
If someone was doing an actual rebuild like this wouldn't you want to use assembly lube on all of the moving parts? Also, do you know if they make parts to change these transmission gears to say taller gears or shorter gears depending on what it's being used for? Can you put a 4 spd setup inside a case that was originally a 3 spd? Also, do you know if you can change an automatic clutch setup to be a manual clutch? Thank you! 👍
Hi Chris! Glad my videos are helping! I rebuilt a 1978 CT70 recently too. Very fun, but unexpectedly complex project. I have a few more in line for restoration soon! Keep wrenchin’! Thanks for watching!!
No mechanic is complete without some brightly colored nail polish in his box. Not only is it good for marking, but it is also effective at sealing welch plugs.
I’m putting together a z50 gearbox and can’t work out which side the washers should face that sit against the bearings on the gearbox shafts They are slightly bowed and I remember you saying they are directional, does the more sunken in part of the washer sit against the bearing or against the gears? I have problems with the sprocket shaft being to short sticking out of the motor causing the sprocket to rub on the case so I just want to get it right this time appreciate your help and videos, they are by far the best online for these mini bikes
Hi Joe. When disassembling the gear shafts, I mark each washer and circlip with a paint pen as you probably saw in the video. That is the easiest way to determine the orientation. If you did not Mark yours, you’ll need a magnifying glass so you can examine each washer and circlip shoulder radius. I discussed how to do this in detail at the 2:00 mark in this video. th-cam.com/video/T16ax-lhT7g/w-d-xo.html
I love your videos and your attention to detail. With a lot of folks buying 125cc upgrade engines, I would love to see you dive into one of those…..I have a CT70 clone with a 125cc Loncin motor with a 4 speed semi automatic clutch….I bet you could gain a huge new following with this…..Lifan is the other popular redo engine….
Hey BtB! I have had that suggestion made before as I have few CT's in my inventory. But, I just can't bear to hot-rod them! I did sort of amp up my CRF70 and discussed that a in the engine rebuild video I did for that bike, but I've never done a conversion engine job because I just love the original Honda's.
I am just thinking it might be a great way to grow your channel…there are so many out here with these engines it would be a real service….maybe make a service book while you’re doing it…I bet you would sell a ton because there is absolutely nothing out here for us…
@@backthebadge4009 Im sure it would be useful to a lot of people, but I just dont have lot of interest in spending money on that motor nor do I have a chassis to put it in! But Im sure you are right - that there is an audience out there for that retro-fit.
Hi Joe! I don’t have a Z50, but I would love to work on one! The motor is essentially the same as the one we build up for the CRF70 project we’ve been working on. Thanks for watching!
Hi Scott ! I’d do a Z50 if I had one! I have a CT70 in my queue which is similar, but it’s not 4 speed. I love those Z50s and would love to restore one.
Brian, your how-to videos are excellent. Thanks!
Oh man!!! Thanks Jeff! Im glad you like them! Thanks for watching!
100% earned a subscription right here. I’m looking to restore my 2003 xr70r and you’ve given me all the information I need! Thank you so much!

You never fail to make amazing rebuild videos. Thank you
Thanks Bluegrass! I have been working for 4 days straight on two new ones for a KLX I'm building. If you find the time, please check them out!
Best series of build videos on these engines. Good job. Ive built many of these. Watched alot of content. Definitely some good stuff here. 👌
Thanks John! Lots of new stuff coming! Thanks for watching and for the supportive words!

I wish I could give this video 100k views it was so helpful
Hey Seth! Your kind comment is more valuable than 200K views! Thank you! And, Im really glad it helped you! Thank you for watching. 👍🏻
@@brian.d.mobley are you going to have a video of the full engine assembly?
@@sethpetras6641 Yes! I have one video to make on installing a high volume oil pump, then I will do a video on the engine assembly.
Thank you for this video.
My pleasure! Thanks for taking the time to leave a nice comment!
Excellent job !!
Thanks Vince! More good stuff to come!
Thx for this vid your channel is so good. Can you pls do more z50 stuff
Hi Joe! I don’t have a Z50, but I would love to work on one! The motor is essentially the same as the one we build up for the CRF70 project we’ve been working on. Thanks for watching!
it would be great if you did a z50 4 speed engine i too have issues with the washers inside , great vids by the way
Hi Scott ! I’d do a Z50 if I had one! I have a CT70 in my queue which is similar, but it’s not 4 speed. I love those Z50s and would love to restore one.
PLEASE DO A CR 85 CRANK SEAL REPLACEMENT ON THE CLUTCH SIDE and can you please do it without having to take the whole engine apart
The Honda service manual covers that pretty well. I’m going to be building a CR85 in March so I’ll create that video then.
I have to replace the main shaft in my xr70r but the one I ordered is different? Was there two different mainshafts?
So sorry. That’s something that you’d just have to research to sure. There are just too many parts and variations for me to comment with authority.
YESSSSSS
Not sure how I missed this one! Thanks Seth!
♥️🥰👍👍👍👍
Thank you!
