I still say HT/China girl engines are cast from melted down Chinese beer cans, and not cast all that well to begin with...
It takes me about 1 hours worth of work with a dremel tool and my extensive set of files and a few sheets or sand paper to clean up an engine for painting or plating.
As with any small engine, popper break in and careful maintenance is a must, avoid excessive idling while not moving...
You would be surprised how fast they get hot at idle. This extra heat causes expansion in the engine parts themselves and that in turn tightens up clearances...
Tighter clearances in a 2 stroke means that the oil film barrier between parts can be compromised...
Thats why some HTs seem to wear out to quickly
Keep the mix a little fat, its better to throw a tiny bit of blue smoke rather than seize a piston.
Dont over rev them! to much time spent at or near red line will wear out ANY engine.
Keep those air filters on and clean... dust contamination in the intake track can be suicide for these things, it eats up pistons, rings and cylinder walls.
Baron was right... some time ya just get a lemon....
I still like the GT5r super rat 66
