Just found your channel today..thank you for doing this allow us to preserve these engine.
You are very welcome. I hope you found the information useful. These videos take a lot of time to make and I don't expect them to ever go viral. But if I can help a few people, then I am happy. I know that they show ads. And I can't find a way to turn them off. I never received any $$$$ from CZcams. And that's fine. I don't expect to get paid.
you're helping more than you know. thanks again@@SoCalBruce
Just saw this video and I was able to put my motor back together, thank you 🎉 I have a 1969 Honda sl90
Thank you for showing this it was a big help.👍
Great video thanks. Also thank you for responding to my previous messages.
Putting my S90 motor together. I really appreciate your organization of the project. Thanks
Glad to help. Thank you for appreciating the work that went into making these videos and commenting.
Thanks alot for the video. Helped a lot 💯
Super helpful. Many thanks.
Glad to help. I hope you get your bike up and running soon.
Спасибо. Снова помогли.
thank you
You are very welcome.
Hi Bruce, I am working on a '74 Ct90 and you videos have been very helpful.
My father had a Honda trail bike as a kid, we're carpenters and have no mechanical experience. Thank you for your videos.
Thank you for the vote of confidence. Sometimes I wonder if I go into too much detail. But I guess an experienced mechanic won't be watching these videos.
@@SoCalBruce Hi Bruce, with the help of your videos, my ct90 roared to life yesterday. Still plenty of tuning and troubleshooting before she is road worthy, but I wanted to say thank you. It won't be long until my trail bike is adventure worthy.
@@davidholm1194 Good job and thank you for the feedback. My intention in making these videos was to show every part of the bike and to give beginners confidence to give it a try. I'm not getting paid for this. LOL. You notice that I don't have any ads running.
Thank you for taking the time to document this so well and sharing your knowledge. I’m in the middle of rebuilding the engine in my CT90 and your videos have been helpful.
Glad to help.
Your videos are life savers! Thank you soooo much!
Thanks for filming. If it’s possible to have too much patience I’d all say you have it lol GET ON WITH IT! But I know ppl enjoy your pace and explanation well done.
Thank you sir for sharing your knowledge and making this video
You are very welcome. I hope it helped you with your project.
Nice methodical video, Bruce. Thanks!
This video will never go viral. But if I can help a few people doing their first engines, I'll be happy.
@@SoCalBruce thats me I bought every single replacement engine part you can think of,a wiring harness,throttle,carb,piston set,drive chain,just finished the engine,its complete..but there are zero wiring videos for these so ill be winging it
Hi Bruce, I tried to start it but no go so far. first thing I looked into was it is getting good spark. next found that I only have fuel going in from the auxiliary line probably because I didn't put enough fuel in, but the carb is getting fuel and has a slight drip I need to fix later. So, reason I'm rewatching this video is the points and timing settings. I have a CT200 similar to the C200. All in one hole to set the points and timing but I believe your process is the same. I have the pointer and the F mark. I was getting confused and now I know what to do tomorrow to get this set. If it still doesn't fire, I'll check the valves. If that is good carb is next. Oh, what is a good setting to start with on the throttle screw and the air screw? I have both set at 1 1/2 turns out from seat.
When you get VERY FAR and one of these videos points out a screw up!!UGGGGH but thank you🎉
I hope you got it right now. You will notice that the second time is a lot easier.
@@SoCalBruce yes,and you now know how to do this forever..its basic back track work its just a pain cause you think of the engine as a fragile object which its not!
Thank you, I have just acquired a 1964 ct90 that doesn't run. With the help of you and a few others on youtube I am thinking make it like new, breaks, forks, tires, engine. My problem is parts, any suggestions.
I'm glad you found my videos useful. As far at spare parts, If you need a lot of parts, a parts bike would be useful. Of course you run the rise that the part that is broken or missing on your bike is also broken or missing on the parts bike. Another useful source of parts is ebay. There are still quite a few new and used parts available. If you want the original carburetor, it is hard to find. The carburetor for your 1964 ct90 (CT200?) was only used for this model and the c200. But one will eventually show up.
hi bruce i have 73 st90 and shift drum has 5 pins would you know where they go 2 short 2 long and the only one left i know where it goes
Thank you very much. you saved me alot of greef . Could you recommend a good version of shop manual?
What???!!!!! You couldn't use this video?
🥰🥰🥰👍👍♥️♥️♥️
Help! AFTER you take the stator/alternator off,how do you get the flywheel out,I can't figure it out
You need a rotor puller. I bought on ebay. They are around $20.
why didnt you show putting in the valves???? thats the only part i wanted to see
Is there supposed to be oil in the stator compartment ? I have some on my 69ct90
Yes. There will be oil in the stator compartment. I was assembling this engine. So I hadn't added oil yet. If you are working on an ATC90, it will be different. There isn't oil in this compartment. Because of this the location of the shift shaft oil seal is different. In the video episode where I ran this engine on the workbench, I took a stator cover off a junk engine that I have and drilled a hole in it for my socket to crank the engine. Later I'll replace it with the good stator cover and use the kick starter.
I just got a 1985 200s and I tried to start it backfired however when I checked compression it doesn’t have more than 25 so I know I need to be way higher what would be your first move on something like that? I’m wondering if the exhaust or intake valve is stuck open? I’m not a engine expert but I figured I’d pull engine out and crack the top end open and look it over.
Sorry I a few months late responding. I didn't see your comment. You can do a leak down test. That will determine if there is a bad valve, piston rings, blown head gasket. But you will still wind up tearing down the top end to fix the problem. That is unless it is something simple like valves adjusted too tight.
Wait !!!! How do you change the oil seal on the cam cover ? You did it off camera :(
Sorry. I thought it was pretty straight forward. You pry the old seal off. There is an oil sealer removal tool that you can use if you want. Or you can probably pry it off with a screwdriver. Look which way the seal is facing before your remove it if you are not familiar with oil seals. Then put a little oil or grease on the outside circumference of the new seal and push it in.
Why all the new engine parts and a used piston?couldnt let it go?Standard makes the best oem version
Hello bruce, I just bought a 70 ct90 and I was checking timing. Using a volt meter that makes a ping noise when checking continuity, one lead on wire one on block ,I spin the motor over and the points open and close but never breaks continuity on my volt meter ,,what would cause this? Thank you
There is a continuous path through the stator coil. You need to set the ohm meter to a very low range to detect the points opening and closing. Or take the points out to disconnect from the stator.
Bruce i have a 84 honda atc 110 engine. I believe needs a valve job... Or a top end rebuild... Would you be interested? PAID of course.. Let me know thanks
Hello Tom, This doesn't sound like a very difficult job. If you want to try it, I'll be glad to consult with you. No charge. I made a video (12 episodes) czcams.com/video/vsvIWAfOX-g/video.html on the 1982 ATC110. It is the same as the 1984. If you want to make it more simple, you can disassemble the top end and send the parts out to be rebuild. Then when you get them back, you can reassemble and tune it up. Here is another video on how to tear down the ATC110 engine "ATC 90, 110 (CT90) Top End Engine Teardown in 17 steps" You can click on this link. czcams.com/video/z4IKjwzNABI/video.html Good luck. I would like to know how it goes.
Thanks Bruce I'll let you know...
