Flywheels Lightened or Alloy on Triumphs

["Terry & Cindy O'Beirne" <esp@hypermax.net.au>]

We do not use alloy flywheels, simply  because of cost.

The Midget/Spitfire 1500 flywheel is a great basis for a competition unit. You 
can 
easily put 200hp thru a 6 1/2 inch ceramic clutch fitted to this flywheel.

Some tricks with cast iron flywheels;
ensure the ring gear holds it all together
never reduce mass near flywheel bolts
have it perfectly balanced
use a scatter shield
