1982 KZ750N Spectre

16 Oct 2017 19:11 #773092 by JohnLuke

1982 KZ750 Spectre was created by JohnLuke

I’m rebuilding a KZ750 with 66mm bores. I would like to bore to 66.5mm. Does anyone know a manufacture who sells cast pistons that are 66.5mm?

Thanks!

If the 1982 KZ750 Spectre engine is/should equal to the other KZ750/4 engines (bore and stroke 66,0 x 54,0 mm)
This should be a option

I'm not sure if this would work but how about picking up a cheap KZ700 cylinder and having it bored to accept stock 66mm 750 pistons?

Those are all nice. Like the 350 dollar set from IMD pistons are good. But the other ones are way to expensive. Is there anything cheaper? Like I'm fine with cast pistons.

Cruzin Image +3.0mm kit is cheap. For all we know the IMD pistons are made by the same company. How to tell quality?
