HANKSXXX Posted March 11, 2018 Share Posted March 11, 2018 I had to do some digging through old invoices (some back to 2007) but that number is correct. I ordered from the custom gasket division of Cometic and specified .075" MLS head gasket for CBR1100XX with 79 mm bore. Surface prep is important and a smooth almost polished surface is preferred...30Ra or so. Some install the MLS gaskets dry and I have also used a thin coating of spray Hylomar...no head gasket failures either way. Hope that helps. Hey xxturbo, how much HP and TQ did u finally end up making?? Quote Link to comment Share on other sites More sharing options...
