Indeed so Lannis. |
But just as the simplest of tools can be the hardest to master (my former machine tool fitter colleagues made hand scraping surfaces truly flat look like a trivial exercise - which it most definately isn't for the un-initiated !), "simple" two stroke engines need everything to be "just so" to run well.
I wasn't intending to denigrate Andy's skills, just trying to point out a potential pitfall. There does seem to be a perception in many quarters that MZs are crude & require little in the way of knowledge or care when it comes to a rebuild. Yet the opposite is the case - they were manufactured by Germans to close tolerances and, East or West, Germans were Germans !
Easy to cause expensive damage without a little knowledge & this is probably the cause for some of the adverse comments about MZ reliability - I cringe when I read of people just "honing out the cylinder & fitting new rings" as part of an overhaul, for instance. On a TS250, the difference between new piston to cylinder clearance and the wear limit is only 0.06mm !
Fortunately the factory manuals are a lot more available now than they were when the bikes were current, so the information is out there for those who wish to look for it.
