Exactly what I did to my previous C5 and will be doing to my present C5 over the winter.
Absolute agree that the ports not matching the manifold, throttle body and gaskets are shocking as standard.
Bore it out to 88mm I can guarantee it will impress. 88mm will leave you 2.1mm liner--ample.
Well, clearly all my work to build race winning, championship winning and lap record setting Royal Enfields has been a complete waste of time, as I clearly could have left the ports and everything else bog standardCranky wrote: ↑Sun Nov 22, 2020 2:34 am
The stop start air flow of a single cylinder is not going to be improved by removing a shave off to match. If it were a multi cylinder its possible a few more pounds of torque can be clawed from such an exercise to increase volumetric efficiency by keeping a smooth air flow..
Quite. Back when dinosaurs walked the earth my brother and I stripped a Morris 1000 engine down completely. We then rebuilt it, with great care, polishing ports, making sure the volume above the pistons in the cylinder head were the same.Bullet Whisperer wrote: ↑Sun Nov 22, 2020 9:55 am
