hi everyone, this may be a fount question that I think I know the answer to. When you stroke the engine say from a 100 to at 103 stroke, this adds another 3mm to the tdc height of the rod and piston set up assuming nothing has change with the pistons and rod.


I would expect it would only increase the TDC height half of the stroke increase, so 1.5mm for a 3mm stroke increase -- the other change would at BDC which would be 1.5mm lower in the cylinder.

Thanks dave, totally forgot that we 1/2 the stroke
