Wait till Norbo gets back of his jollys this week mate. He has done a 410 conversion (I think its 410) using jet ski pistons if I remember correctly. That should give you the extra cc's you are after.  |

The only bit I know of the usual 375cc conversion is the use of DT175 pistons and the need to shorten the barrel (the bottom) by about 5mm.
You can usually tell by the 347cm3 cast at base of the barrel being machined half way through so there isn't much of it left to read.

What no one seems to mention is that the 'marginal to begin with' 350LC transfer portings/castings get significantly reduced when one Bodges in a Larger liner.
Bigger Bores with a reduction in transfer capacity ?
Now's there's a well thought out 'improvement'
