Right then, Saturday finally after delay after delay, the crankcase had been delayed by 3 weeks the head by 2 weeks, & then the gasket was 2 weeks late which turned out to be the wrong one so took another fortnight. Dealing with all these folks over in the US wasn't easy. So previously my lovely with a flash K&N race filter simmi system gave 169.31 BHP & 77.69 torque going back on the same dyno at ZX10Rich business RK Performance with a +2mm bore, properly ported head, re-machined for +1mm valves, JE High Compression Pistons, lightened balanced & knife edged crankshaft, balanced rods, Kent Cams, Arrow full system, all new big & little end shells & main journal shells, ceramic transmission bearings. I was being cautious with a standard depth head gasket & stock timing rather than dialling the cams in for now with the plan to break her in on dyno using the motoman method. Rich did this then we changed the oil to a semi so rich could get on & re-map her so she then made a credible 195.48 with an extra 8 torque
I could not be happier knowing that in 500 miles I would remove the head to check the bore & then drop the head & dial in the cams I believe 200BHP Is possible. A true 25BHP to date on a new engine is remarkable. When some of you have posted I will write the rest of the story.
