Hey, I'm having to downsize my garage, so can't hang on to my crate of spares "just in case", all from a 2004 MX125SM (all interchangeable with MZ125SX) I've got:
£120 2004 engine, compression is low on it, I bought a head gasket kit (something like £40) and fitted it (correctly, I know what I'm doing) and still poor compression. Must be the valves (wish I'd had a leakdown tester before starting), valves are moving/seating nicely (no bent stems) and timing is spot on, so you might get away with just re grinding them with some paste, or worse case scenario, send them to a shop to be reground. I've already robbed the starter clutch out of this one - other than that, all is present.
£50 ignitor box, confirmed working.
£10 loom - the connector block for the ignitor has been lopped off, and the idiot lights have been chopped around for a custom tach/speedo - I couldn't be bothered screwing around with it as I had a spare complete loom - might be good for someone though?
PM me if interested.
Cheers
