Thanks SR Mailman, Nice to know some of my well earned things to say are not falling on deaf ears. Not saying that everything I say is gospel, But I've learned a thing or two fooling with 2 wheels on and off for 30-40 yrs. And some things don't change. Even with the latest,greatest performance chip. lol

The 229cc engine design already has an as large BBK head on them as is possible.
I mean, perhaps you may find a fitting 239cc, but think about it,
the original cylinder was a 125cc cylinder, which they overbored to a 229 already.
I'm not confident that the engine will last as long as a normal engine because of this!
