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.

A 3D Printed Air Intake Boot for use on a Honda CT200

Image
 Recently someone on my Facebook page commented about a post I did where I shared information about a 3D printed air intake boot I designed for K0 CT90's and asked if I could design one for the CT200 and even offer to let me borrow an old CT200 air boot that had some issues to use to help construct a design. Related Posts: A 3D Printed Honda CT90 K0 Air Intake Boot Well I've actually had an old CT200 air boot on my desk for over six months as creating a 3D printed design has been on my list of things to do for quite some time. With the encouragement from the comment I received on Facebook, I sat down and created an initial design using my ViaCad 2D/3D Pro modeling software that I'm pretty happy with. Here is a picture of the 3D printed design I came up with and printed next to the stock Honda CT200 air boot.
