I finished up replacing the front fork seals on my 74 CT90 - it's a completely different bike now. I rode it.  Put in some gas and rode it some more.  I also put in some tire Slime today  Now I'm thinking about repainting the gray down tube cover.

And it's not a CT but I played with both of my ST90 bikes - changed out the 65 main jet for a 78 main jet. The motor only has about 17 miles on it and was running very lean (had to add choke at WOT) because of being bored to the fourth oversize and because it has the longer duration Dr ATV cam in it.  Last week I had to replace the advancer on this bike because the advancer springs had lost that lovin' feeling and went to full advance way too fast - no way to set a low idle. 

  All in all, I am still trying to get this engine dialed in due to all of the changes done in the rebuild.  But it starts on the first kick and the 78 main jet gave me about five more MPH - up to an indicated 47 MPH now.
