I hear what yer saying ck70 and the fact that I don't even run china girls makes my point useless anyhow. The only 2-strokes I run as of late are CY 46cc chinese Zenoah clones.
The CY46 is recommended to run only 25:1 period. I have found this to be true as I was running a full blown CY46 at 32:1 and it didn't last very long at all.
When someone runs a CY46 hard for say 1 year using Opti2 @ 100:1 and it's still running.......get back to me!
( for the record my CY46's turn 18,000-22,000rpm maxed......seriously)
