I'm probably gonna ask a lot of questions...
Just a little update just to keep a record of the million year rebuild.
Had the motor cases split, checked all the internals and everything looked fine. Blasted the outside of both cases, refinished the matting surfaces, polished the races, reinstalled all the necessary components and put the cases back together with a new cam chain in place. Right now it sits waiting for me to fit the piston rings to the cylinders before reinstalling them and then putting the head back together.
If anyone is actually looking at this anymore, and you verify the following: the manual I have downloaded says the Top Ring (second) gap should be between 0.3-0.5mm and the oil ring should be between 0.2-0.4mm. (My cylinders, pistons, and rings are all 0.75 oversize)
With a complete tear down like I have, what is the next step y'all normally take? Electrical? I feel like my next course of action would be to get the bike put together with just the essentials to test out the motor and make sure that the rebuild was successful.
...
In other news, we've added a running (thank god) '73 CB125S to the family for my wife's first bike. I can already tell that this thing is going to be outgrown quickly. Anyone know anything about these and how to get a little more muster out of it? Looks like it tops out around 55 mph right now. Still needs a good bit of work, especially with the throttle and all the cables, but it runs so thats good.
