Motorcycle Repair: base cylinder leak, clutch side, rear cylinder

Question
i have small leak( a spot of oil) on the rear cylinder on the clutch side, this has been going on for a few months, do i need to worry about this and get it fixed or what should i look for to help make my decision to repair it. is it true that if i let the bike warm up for a few minutes before riding its possible the seepage would stop.

Answer
Over time it is only going to be worse. So you need to repair it. If it were me, I would have both done at the same time. That way, down the road, if the other one starts leaking you dont have to do the same work again.
Good luck and happy riding
