I've got an accurate "timing tape" stuck around my flywheel, that shows all 360° marks on the tape. I use a timing light and adjust the mark when the light flashes to whatever degrees of timing that I want when it lines up with the mark on the case. I usually run about 27° BTDC on my 88cc big bore motor. This is with premium 93 octane gasoline.
Hey what on the inside of the rotor makes the points open and close? I saw where something might have been at one point close to the keyway. Any video or pictures would help out alot, its a CT70 with the Hitachi ignition.
You touched on issues any of us have had issues with, restoring Mini Trails I have always gone static at first, But always backup with the light. And you stated that changes still can exist.. This video you did is probably the biggest issue people have with getting a bike tuned next to carburetor problems. But the nice thing if you stick with it, and study manufacturers repair books, it becomes easier to diagnose issues. We all go thru grey hairs, parts changing, and hit and miss. After 35 years working on the Mini Trails you will still hear me say. " You have got to be kidding me" One of the better videos I have seen
Thanks Chris! I have a new one coming soon on rebuilding the ignition. I got a little behind because I was restoring a 1994 Bianchi Road Bike, but it won't be long! Thanks for watching!
BRIAN LOVE YOUR CHANEL.I HAVE A Z50A MOTOR AND SOME ONE PULLED THE CAM TENSIONER PLUG AND LOST ALL THE PARTS LIKE YOU SAID,I CAN'T SEEM TO FIND THE PARTS,DO YOU KNOW WHERE THE MIGHT BE AVABLE ? THANK YOU CLIFF
Brian, you sir are a gentleman and a very good professor. Damm well explained and showed. One of the best channel on TH-cam that helped me restore my ct70.
With the timing light method . I’m getting slight bouncing around from my timing light on the “f” mark . Is it suppose to stay fairly steady on the f mark or can it fluctuate a little as long as it lives in f mark. Any ideas on what might be causing that .
Hi Sergio. I don’t know what you mean by “bouncing,” but the moment that the timing light is triggered by the pulse from the spark plug lead can vary - mostly due to engine RPM. If the motor runs fine and is is close to the F mark when illuminated by the timing light, its fine. These motors can vary quite a bit and still run fine due to their low power output in general. Hope that helps. Thanks for watching!
Es una chispa perdida. En un motor de 4 tiempos a platinos hay ina chispa cada vez que el piston sube. Esa chispa salta antes en la carrera de expulsión de gases cuando hay baja presión.
Thanks TF! You have been a tremendous help to me on so many bike issues. I really appreciate your help and I hope I can pass on your knowledge through mediums like this video so others can learn and benefit.
سلام استاد یک سوال داشتم اگر رینگ وپیستون موتورسیکلت را عوض کنیم برای آبندی اگر موتورسیکلت در جا کار کند برای موتور مشکل پیش میاد منظورم این است که در جا آبندی کنیم اصلاََ سوار موتورسیکلت نشیم در جا روشن باشد به موتور هم استراحت بدهیم یعنی اگر موتور داغ کرد استراحت بدهیم دوباره روشن کنیم برای موتور مشکل پیش میاد؟بعضی میکانیک ها میگن که موتور در جا کار کند بهتر آبندی میشود. لطفاََ رهنمایی کنید ممنون
دقیقاً منظور شما را نمی دانم، اما یک رینگ و پیستون صحیح برای دوچرخه شما ساخته شده و با تلرانس توصیه شده توسط سازندگان و نصب شکاف رینگ، چه سرد و چه گرم، روی موتور تأثیر منفی نمی گذارد.

sweet video but audio only on the left channel. nothing coming out the right side :/
Por fin , tuve que buscar en inglés para que no sea un colombiano hablando de motos
Excellent video showing all of this information.
Hey Nick! Thanks! I hope it helps a lot of people! Thank you so much for watching and for taking the time to share your kind words.

theres a cam lobe that opens and closes the points

Thanks Coeur! I appreciate the feedback!
been watching your videos .thank you so much .so helpful
Thanks Chris! I have a new one coming soon on rebuilding the ignition. I got a little behind because I was restoring a 1994 Bianchi Road Bike, but it won't be long! Thanks for watching!
I learned the light bulb method...But, I have a old timing light...I did video's of me tearing apart my CT0 '74'...
I think the timing light is the easiest way. Thanks for commenting!
For a perfectly accurate setting with the timing light, shouldn't the engine be running at a specific RPM? Thanks for the video.
according to the honda manual, it says 1500 idle RPM
Nice job! Good video Brian
Thanks Shawn! That one was a lot of work!
Can you use a 12v battery and bulb?
Hey Barry. The short answer is; no. Not on a CT70

سلام استاد تست که با لامپ چراغ کردی سیم آبی چه سیم است سیم pickup است لامپ چراغ روشن شود تنظیم است یا خاموش شود تنظیم است لطفاََ واضح تر تشریح دهید
این وایر ground هست. لامپ هرگز خاموش نمیشود فقط کم نور میشود و لامپ همیشه باید روشن باشد.
👍♥️♥️♥️🥰🥰🥰🥰🥰
Thanks
Excellent video
Thank you! Glad you found it useful.
سلام استاد خیلی یک ویدیو عالی است اگر واضح تر تشریح بده خیلی خوب میشه تشکر تشکر
سلام چه اطلاعات و یا جزییاتی مورد نظر شما هست؟
منظورم این بود که لامپ چراغ در علامت Top کم نور باشد تنظیم است یا پور نور باشد تنظیم است
وقتی نور کم است تنظیم درست است.
عالی استاد . استاد فیسبوک یا مسینجر نداری من میخواهم بهتر با شما آشنا شوم ممنون
