Didn't know how it all works, this animation is very well done I think. Maybe others here have seen the video? This is the first I've seen of it. https://www.youtube.com/watch?v=g8xnIFf4id4&ab_channel=TecknoMechanics |

I've never torn into a MC tranny in all my years of riding and wrenching, so I did not know how they really worked. Excellent video - thanks for sharing it!

I spent a few weeks last winter inside a 1971 Honda CL450 transmission. I moved it in to my house workshop from here and played with it for a few weeks diagnosing a problem (bent shifter fork). The fork was probably only bent 1/4 inch but that was enough to cause it to pop out of 1st when I got on it. The shifter forks sit under the gears shown and move the gears from side to side depending on what gear the rider selects. I could sit and run through the gears on the bench; fun to play and learn from it.  |

That brought back many Late Night memories of rebuilding my YA5 Yamaha. Pull the jug split the cases generally a bent shifter fork. Designed as Motocross M/Cs was Not the YA5. But it was a fairly stout patform. Friend bought a then New Kawasaki 238 Motocross bike. All we everr did to it was change sprockets and expansion chambers. 2 strokes were Still king then 1966 1967. Very Intersting animation. Followed that up with the clutch vid. RIDE SAFE.

That was cool. I've often wondered how a constant-mesh transmission didn't tear itself up. I didn't realize that the gears free-wheel when they're not actually engaged.
Thanks for sharing.

Serk that was great!
I'm glad some enjoyed the tranny explanation, I too didn't know how it didn't rip apart in the constant mesh format.
How often have folks here replaced clutches?

And the bolts are laid out in position of removal. Sometimes one just has to make do with what is on hand; I do not plan on ever being in that transmission again. Hopefully. |

I long for the day when I can have my own shop on a big enough property where I can build whatever buildings I need or want. That stump in the photo really reminded me of what I don't have living in plastic banana land among the rich and not-so-famous in California. |

I could sit and run through the gears on the bench; fun to play and learn from it. That was the only way I really understood how engines and transmissions worked. In the winter I would roll my Suzuki 90 downstairs and take it all apart and put it back together. Must have done it 10 or 15 times. The rotary valve intake on those were very interesting. A while back I had a HondaMatic 400. I could never understand the concept of how it worked. Thought about tearing it down many times. Wish I would have. |
