:hello:i've installed the 0.45 to my 04'(plus the intake cam and headwork due to race manual,and the ONLY ''problem'' i faced,was that the safety squash limit was 6mm(kawi race manual says no less than 7mm]but in a years period(more than 25 trackdays ]faced NO PROBLEM AT A L L!!!
I dont know what you guys are worried about.I milled off .015 off my head which is more the double of your thinnest gasket and I still had over .100 pvc but i used a stock thickness gasket.I think i could of got by with the 45 mm gasket which is .007 thick. No problems here.As far as the squish I had .006 from the top of the piston to the top of the cylinder.I also have the race intake cam 107/104 LC
pull the head for maybe two hp, I dont know fellows that sounds like a waste to me. Droping the motor for 2 hp dont make sense to me, but thats just me. I think if I was to drop the motor I would have to do more than just head gasket.
