New kid on the block, 1971 CT90 survivor.

Hi gang, Wayne in Callahan FL 32011, next to Jacksonville FL.
Got about 10 hours into the initial clean up and sorting things out. It's Alive! runs good with a little over 12,000 miles. Here are a couple of Pic's for you, will be hitting you up for some questions as I go.
First off I'm 170 pounds but the bike will only do about 22 to 24 MPH have not checked the points yet if my memory is correct these should do about 40 MPH? I'm 63 so I remember these guys!

Nice looking and very clean. If it is not smoking, I will bet you that the spark advancer mechanism behind the points plate is stuck . . . rusty. But use caution here before you take it apart to clean it because there is a 50-50 chance you will put it back together wrong - spark will occur but will be 180 degrees out of phase with the combustion cycle.

Use a sharpie marker to put some orienting marks on it so that you can put it back together correctly.

Very nice bike!!! I weigh 200 pounds and both of my CT90’s will cruse at 45 easily and both are 100% stock. Welcome to the forums and don’t be afraid to ask any questions here.

Before anything else ;

Tune it properly beginning with a valve adjustment, then points gap and ignition timing to the "F" mark, this is critical ~ many (? most ?) use the 'T' mark, that's for Top Dead Center, not timing .

Once all that is done, remove the carby and inspect the main jet ~ msny still have the smaller # 62 or #65 main jet and it should be a #72 unless you're in the mountains .


The order in which you proceed will define how well it runs and how much you like it .
