Well.. it may not get as many views as "Gangnam style", but there are some nerds out there, I'm sure!

And now the Easter Bunny:



Needs some grinding between the dish and the pockets. The dish has to be this large to lower the compression ratio down to reasonable 13,5:1. This set of pistons will make the squish appr. 1,0mm, which hopefully will prevent knocking.

I haven't been following your work. Why is comp ratio 13.5:1? Different head set-up, taller piston, longer rod?

Thanks.

Sweet piston, how many grms?

Thank you for the Video, very interesting to some of us

Specially made for you, Spanner!

Because I wanted it to be 13:5. The short answer to the other questions is: Yes.

If you are interested, have a looksie at:

There a some more videos describing my projects in my channel, if you're interested!

Thanks!

Appreciated

That is an older head, I can see where the seat is so close to the
water.
I wounder if the larger valve heads 37mm vs 35mm would have
more material in those areas?

Cheers spanner

I wanted to thank you again for the videos! gold!! I thought I had seen them all but discovered a couple I had missed - very interesting (and thank you for your patience and answers to some questioms the other day related to EFI which are already in the earliest videos)

one question - as I understood it, the Cannondale engine lives or lived on as a 450 - which make? I couldn't quite make out or recognize it from the video (first or second video I think)
