Ah! Your right I did blunder there.your not getting JE Pistons mixed up with JP Pistons are you Ron ?
Laverda SF said:ROSS Pistons and Deves Rings are probably the only MFGr's presently tooled up for our old Brganze Engines.
They are not, actually.Asso(Italy) and Omega(UK) both make an excellent forged piston,

Glad to hear the (as yet unused) pistons I sourced from Riccardo many years ago are of excellent quality - they are certainly heavier than the std Mondials, which worried me at the time. Prob is if I go to big bore I'll need to sell them!
Damn, Piet! So the 'new type' implies that the 'old type' were sub-par? Oh well, don't need them any time soon ... but I will have a squiz and see what I've got. My factory 80.0mm Asso SFC numbers are still sitting unused in my parts box about 40 years after I bought 'em! Have had a great run on the cast Mondials, even after bumping comp to 10.5/1 and taking a frac of the squish band to clear the head.sfcpiet said:Quentin,
Grant and I had a lengthy chat with the boss of Pistal at last years Intermot show in Cologne. The new type have only been made recently on Riccardos' request, do check what you have.
