Alright Guys the proof is in the pudding right? Well I just finished the Landspeed racing season. One set of pistons all season, lot's of "unofficial" testing (I am not endorsing Landspeed bike testing on the street...) and 2 trips to the dyno, still not noisy and I just put in the seasons fastest pass for the bike Saturday at 143.767mph, Highly modified RD250, no fairing, on gas:) Ed
