Honda CT90 Engine Reassembly

Image
I have one 1971 CT90 where I was going to rebuild the clutch because the kickstarter just wasn't turning over the engine like it used too,  and I also had a Big Bore kit from DrATV that I wanted to install. My intent was to just do the top end and rebuild the clutch with new disks, but when I opened up the cases to rebuild the clutch pack I found a slick black slime in the bottom of the case.  I didn't like the idea that there could be black slime in the rest of the engine, so I decided to disassemble the entire engine to make sure I cleaned everything out.  Since I was tearing everything apart I thought I would document step by step how everything goes back together in this post in case others were interested in knowing what the inner workings of a CT90 engine look like.

Adjusting the Clutch on a Honda CT90

I recently did the video at the link below on how to adjust the clutch on a Honda CT90.  The method I show in the video would apply to Honda CT200's and many other Hondas that have an automatic clutch.



I hope you find the video helpful.

  1. I have a question. When you watch the shifting, it would appear that the clutch body would be compressing the plates together when you shift, not releasing them. I know this isn't happening because well that is the sole purpose of the clutch, but is there a way to explain how pushing the clutch body towards the bike somehow releases the plates?
