THE ENGINE The engine was built as a one off with most parts
custom made by myself or to my specifications…. It is currently 700cc with a 93
x 102mm bore and stroke a 1 ½” GP carb
an old BTH TT magneto 14:1 compression
ratio and runs on methanol with a small dash of Nitro… it will happily rev to
7,000rpm….. It is quite easy to alter the engine between 650 and 750 cc but 700
was chosen because I considered it the best compromise between reliability and
power. Horsepower…..enough…. as long as it doesn’t try and
escape!!!
The hi lift rockers were whittled from a billet!
The oil pump has a third scavenge stage directly from the timing chest.
The head studs started life as foot long Allen
bolts.
Pushrods are a massive ½” dia .
Rocker Box gasket !!!!
The barrel is machined from a solid hi tensile iron
billet.
The repositioned valves are Titanium with a 2 inch inlet with Copper Beryllium seats.
The crankshaft has a custom Carillo rod and Venolia
piston.
I think I know where it all goes!
A Velo engine, an Amal GP, a megaphone exhaust........ what more could you want!!!
