Yes I will do the first ones with liners , everybody can fix those ! And are easier and cheaper to install and make .But I will try out the alloy Nikasil on my planned Bonneville racer ,I dont know if Nikasil gets on with a Nitromethane !Because thats what Im running it on .But ofcourse I will be road testing both liner and Nikasil on the road ,on petrol , puttinga few thousand miles on the clock.Before hitting the salt .Price , yes your about right ,but I havent worked it all out yet , as its not just the cylinder +liners+plus longer crankase studs as the barrel flange is now 17mm thick .But it will be in that ballpark figure ,as I want to sell them and not have a very expensive toy !!
