howdy, my name is walter, I'm old, 44, but my Dad is 75 and his blaster keeps up with mine just fine. (he used to race Bultaco's in the 60's when MX was called hare scrambles and such) my blaster is slowly creeping away from stock with reeds, spacer and jets. the airbox is open, has extra tooth on front sprocket. and I needed taller bars and switched to a twist. could not get used to thumb rig. set in my ways I guess. I am looking for anyone who has used Vito's high compression gasket kit. is it good mod or what?
