CT90 Restoration Adventures

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.

I was recently looking for an inexpensive all around tire and when I found the DURO HF307's in a 2.75 x 17 for only $23.12 at Cedar Rapids Tire I decided to give them a try.  The DURO HF307 is DOT approved and has a trials style tread pattern which is just what I needed for my casual around town riding.
