How long has the motor sat before you ran it? You may see those numbers come up as you ride it. Even if they don't, if it runs well I wouldn't worry too much about it.
This has been sitting since mid/late last summer. Before that it sat for at least a year according to the previous owner, maybe two.
I'm not going to be riding this one. After it failed I stripped some of the best parts for the 79 and I'm not going to expend my efforts on two 1300s. The exhaust is also in bad shape so it would cost too much to make it sale worthy in its current condition. Once I verify the engine compression add I'll be yanking it out and selling it. I'll part out anything else I don't want to keep for the 79. I have pretty much a brand new top end, big bore kit and pistons should the new motor ever need them, or I may sell them as a package. Pistons, rings, bug bore cylinder and reworked head.
