Mine is just machined too, no need to weld the back of the casing, when i say machined what i realy mean is trenched out with a square edge 1 inch long stone fitted to my wolf drill :lol: I just took the case out until the crank turned with out catching, strangely though, I had to take a little more out for the JB crank than I had originally taken out for the Tino 62 that fell to pieces.

Did you re-angle the boost port also? Made it a bit steeper maybe?
it was just a little less than std
Do you mean less as in angled more towards the exhaust, or less as in steeper towards the head? :-?
