>From my old dirt bike days. I think I remember you got to be careful
with Champion, their heat range gets HOTTER as the numbers go up, NOT
colder as NGK!  We always ran NGK 7-9 heat range in 2 strokes.  For
desert racing as CD ignitions came in and oils got better(@50:1), we
used the coldest - 9's.  I ended up never using Champion's because of
the numbering. Seizing was the most common 2 stroke problem usually
caused by lean carb jetting and plug choice.
