Starting the assembly of the engine cases, transmission, bearings, and oil seals. Discussion about used cases that I got. Converting a AT-1 Yamaha to a CT-1.
Dale, I just started tearing into a CT1 with my 13 year old son. We're watching your videos together and learning a ton. The engine was left outside for the last 35 years with a loose spark plug. As you can imagine, there are a lot of rusty parts that need to be replaced. Where is the best place to find replacement seals and bearings? Thanks for sharing your experience with the rest of us, it's a real gift.
Hi Chris, all the bearings and seals are still available from Yamaha, you can order online at Partszilla.com or Rockymountainatv/mc.com or straight from your local dealer. I usually buy bearings from a bearing supplier, much less money than Yamaha. I am glad to hear of the father and son project. You both will enjoy the time working on this old bike. They are fun and simple. Best of luck with your project and thanks for spending time with me in the shop.
Looks Good! I tore down my 1970 CT1b engine...have the rebore completed but waiting for a shop to finish with my crank assy rebuild. Can't wait to remember how to put everything back together!
Hi Joe, sounds like your getting all your ducks in a row for your build. Getting ready to start the CT2MX engine build for the AT1MX, will be building the AT2MX engine also. This is a really fun build mostly because I dont have to mess with lights and wiring. Love messing around with dirt bikes. Good luck with your engine build, I sure you will remember how to put it back together. Thanks for following the channel.
Thats a great family project, so glad to see dads getting the family involved. I hope you can find some value in these videos, I am by no means an expert on these bikes, I just enjoy them like so many other folks that grew up on them. If you have any questions please feel free to comment, I try to read all comments every morning, maybe I help in some way. Welcome aboard, and thanks for following the channel.
Dale your the greatest.im having a hard time getting he transmission bearings for my 1970 Yamaha Enduro ct1 175 Enduro any suggestions.your friend Mark Lucio from San Diego
Hey Mark, man those are all common bearings, the only ones that are hard to find aftermarket are the two needle bearings, they are still available from Yamaha. Drop me a line at dsweger@bresnan.net
Mister Sweger, I am currently trying to get a 1971 125 Enduro AT-1 up and running. It runs well but we have ran into an issue when the bike runs for a little bit and gets hot. The gearshift will get stuck in between what we think is third and fourth gear. Would you have any insight? Sorry this is so informal, I couldn’t figure out how to message you directly.
Hi Robert, sorry your having trouble with your bike. Not really sure what heat has to do with that problem. But it sounds like it may need the shift arm/shifter drum, adjustment made. I have done at least two videos on that adjustment. It will shift up ok and when you start coming back down it hangs up and won't go into gear. You can reach me at the email below and we can discuss it further. Thanks for spending time with me in the shop! dsweger@bresnan.net
Hey Dallas, you bet, everything in an AT-1 and CT-1 will interchange. You can even put the cylinder, piston, and head on a AT-1 and convert it to a CT-1. Have fun with your project and check back for more early Yamaha enduro repairs. Hey thanks for hanging out in the shop with me.
Hey Dallas, you would need the stator, flywheel, wiring harness, battery box, 6-volt battery, rectifier, and all 6-volt bulbs. You would also have to pull the alignment pin for the AT-1 stator. Think that's it. Not sure. You can use the AT-1 system but probably won't be able to use the electric starter. You would have to kick start it.
@@dallashughes4721 I see, Im not a fan either, dont forget the unique hardware like the flywheel nut and washer and the stator screws, the rest should be pretty common metric hardware.
