Thanks for the earlier reply regarding the AIR & OIL leakage through breather. could you send the details for overhauling ZR250 screws with parts. to recover the machine. which will be helpful.
You’re welcome 🙂
There is no overhaul manual for these machines – but I have the partlist/drawings of a ZT250, which is similar but air-cooled. Send me an email and I will send it to you.
