    Hello all, new to this forum.
    Recently purchased a 1982 xj650 Seca for a pretty good price. Cafe racer inspired, took it straight to the mechanic to get things running.
    Everything went well after picking it up but cut off due to the rectifier being disconnected. Reconnected that and so far so good.

    had some trouble starting it again but eventually turned over. I’ve noticed that there is some smoke coming from the crankcase filter?

    only happens at idle. When riding, no smoke. Is there something internally with the pistons and/or cylinders?

    also will like to add that this bike came with pods on the carbs and filter? on the crankcase

    Not sure why I can’t attach any photos.

    Any advice is greatly appreciated.

    Will take it to the mechanic next week again. Just want to enjoy a ride for today
