Quick Question

[PiercedE30]

I'm doing some math and I would like to know what the combustion chamber volume (in cc's) is on a NV-M50. Or the piston dome/dish volume (in cc's).
I can't do the syringe and plexi method because I don't have the motor apart yet. Any info would be greatly appreciated.

so no one knows?

[tjhartge]

i believe the CC can be calculated by the bore and stroke of the cylinder, saw it somewhere, but i can't recall now.......

[euroshark]

No, thats for the cc measurement of the cylinder itself. The combustion chamber is a separate measurement because it is a dome shape that fits over the top of the cylinder...

Sorry, I wish I could help!

[PiercedE30]

if anyone knows the piston volume i could work with that............

Ive got a refurbed NV head here. Tell me how to measure it and I will help you out

[PiercedE30]

How-to for cc'ing a combustion chamber

It would be greatly appreciated.

I got just under 26ml second time round.

First time made a right mess, air tool oil everywhere, should have leveled up the head first

[PiercedE30]

coool!!!
thank you very much!!

[PiercedE30]

oh, was the head resurfaced or shaved?

[DanThe]

Its been refaced but only slightly

[PiercedE30]

Ok, cool. Thanks.

when i did mines before it was touched i got 32ml on the head and83.32ml on the stock pistons but i cant remember if it was with teh s50 crank or the m50 crank.
