Billet Cylinder

[SUPERTUNE]

Not worth the $$ to build anything but at least an 8mm stroker, just need a couple of sleeve sets for bore sizes to make legal sizes for those that want to compete in cc limited classes. 8mm stroker with these bores...

This could be for amateur 800cc IJSBA rules
81mm bore = 783 cc
81.5mm bore =793 cc

These could be for amateur 900 cc APBA rules
85.5mm bore = 872 cc
86mm bore = 883 cc

This would run in pro classes
90mm bore = 967 cc
91mm bore = 988 cc

updates?

It was fine at the end of last summer but got a bit too cold for these old bones to do much with. When it warms up a bit in a few weeks I will start playing with timing curves and props etc.

Chris, where in Oxford are you located? Just curious I was born there.
My brother machines and builds F1 race engines, somewhere near there.

Ha small world, this seems to be F1 City within a 20 mile radius we have Williams, Maclarren,Renault, one of the Jap teams (cant remember the name) not to mention Kenny Roberts and Pro Drive. Which one does your Brother work at? We are just about 1 mile from RAF Benson.

I used to date a girl from Benson, and I was in and out of RAF Benson for almost two years.
I'm not sure where he works but I'll call him this weekend and find out.

If you're ever over for a visit feel free to pop in for a cup of tea.

No not yet it will be some time before it goes on a Dyno if ever, to be honest I,m not that interested in Dyno figures, particularly on a freestyle boat.

Better still come on over here, and bring a cylinder with you.
Cup of char sounds good though. They drink it iced here, and I can't say I blame them. It was over 100 here in Atlanta during the Summer.
