Don't know if mopdog was referring to us or not, but we cut the decks on a few of the first 206's that had no pop-up. It's not difficult to do at all. (and it wasn't stupid either)
It is
NOT something that we do any longer, since the deck height and piston pop-up is all so close already from the factory (thanks Dave!) Having the engines verified/certified by the factory was a big step in limiting what was being done to these engine from the factory. Seldom do we pull a head anymore on a new LO206 engine. There's really no need to.
Here's what we do on our race-ready packages: We retorque the head, retorque the flywheel, set the coil air gap, align the intake, set the carb floats, and set the valve lash.
We can pull the head, cut the seats and lap the valves, check/set the ignition timing, and dyno tune the engine for guys that want that done, but it's really not necessary. In fact, many guys simply purchase the engine and make many of these same adjustments that we make on their own. It's not that difficult, but for the guy that's a bit intimidated by setting his own floats or valve lash, we'll gladly help them.
The LO206 engine is the most reliable, most affordable, racing engine available for karting today, hands down. No politics, no constant rules changes, no multiple importers with different specs, no "latest-greatest" parts, no tech updates every couple of weeks, no color of the month engines! LO206: Pull the rope and race! What's not to like?
Thanks and God bless,
