118hp 916 Biposto
The whole 916 Biposto
engine was given a full engine blueprint with a balanced crank/flywheel
assembly. The heads received a full flow bench
work-over using the original stock, but modified and polished
valves with new colsibro valve guides for reliability reasons. The
heads were milled for more compression and cams degree'd to standard
specs. This engine has zero special parts. It's still using stock flat
topped 916cc pistons, stock throttle bodies and a stock 45mm
exhaust system with open cans. Therefore this project is a test to
make the most of all the standard parts and I can confirm it works .
Below are some
pictures of the special re-shaped heads with colsibro guides, modified
combustion chambers and polished valves.
Every cylinder head
received at CJS gets the same standard of work!
