Here's my experience with copper gaskets; I run big bore Suzuki SV 650s. Anything over 2 millimeters overbore and you need to run a copper gasket. We do use a peratex spray on them during assembly. We do reuse them,we anneal them at 400° and then let them air cool. Big bore SV 650s have problems with any head gasket you use on them, just less with the copper. I am still working on figuring this overheat issue out but as the race season has ended here for a few months I will take that time to get it dialed in.
