Hi guys, greetings from Italy.
I'm refurbishing a GSX-R 1100 H engine I got for free years ago. The previous owner told me it was used for track days and tuned up a bit, but it looks completely stock to me.
I have a doubt anyway: the head plain is very low around cylinder 4-intake side (at the same level of head cooling fin) while the other side is higher, about 1,5mm more. Is it normal or is it the result of a bad machining work?
Low side, same level of fin
Opposite side, much higher
Thank you
