Bis flywheel weight.

[1973/126]

 
 Can anyone of you bis boys weigh the flywheel for me, if you got one to hand?
 I checked the one on the bis engine which came with a Blitz buggy I bought and have been advised it is lighter than standard, so wanted to make sure.
 Unfortunately I can`t find the information anywhere on the net.

 Well I didn`t wanted to say boiler boys

 Got it confirmed now and the standard bis flywheel is 6.7 kg.
 I was surprised as it`s actually lighter than the air cooled 126 by about 0.6 kg. On the other hand the bis front pulley is about 0.5kg heavier than the a/c 126.
