Just heard some gossip from the last round in the Italian classic series.
Fastest 500/4 guy here (and the race winner), was disqualified for running a 650 head on a 500 in a post race check......
The funny thing is that this year he is so far ahead of anybody else that he really doesn't need the advantage.
in 2009-2010 he was the only one managing to run with the lone Paton 500, but this year the Paton rider is gone and he is pretty much running his own races.
Might explain why he once told me he was seeing more than 67hp from this motor
He is going to fill in a protest in any case, as the rulebook isn't that clear on the subject, doubt if he'll get his trophy back.
Just in case any of you was planning on using a 1979 650 head on older period bike.....
