Re: The KH Project MK II

Lee, the early type conrods have bronze small end bushes. On the later type the gudgeon pin runs directly in the alluminium. Further more the end caps on the later ones are more sturdy...

Photographs show later type.

Re: Ariel twin

Thank you John.
I measure (on a letter scale) 185 grams for the bare piston, and for the complete (piston, rings, circlips and gudgeon pin), it shows a total of 250 grams... This is a 0.20'' piston from the club, make unknown...
Regards, Paul

Re: Ariel twin

Lee, I did buy 6.8 : 1 pistons. Do you want a higher compression?

Re: A matter of weight...

Lee, engine modifications for 1951 where weight increase of the crankshaft with 20%, barrel and head increase finning depth, different rocker box covers (round type). So all in all your heavier crankshaft is correct if it's a 1951 engine! :D

Re: The KH Project MK II

Today I did received the KH pistons from the club. Weight seems the same as the originals. They look fine :D
Top ring chrome, middle normal, oil control rings are in a different configuration as you can see on the photograph.
Thanks, Colin!
