Free Air Weight

by Gene Jens in 2 Stroke Technical Questions 2 years ago

My search skills are lacking.

Trying to find the weight of the Free Air versions of the 377 and 447. Compared to the standard fan cooled versions.

Can't find any published data - Hope someone has weighed one.

Thx

I have reviewed the suggested documents

All of them list the weights for the Fan cooled versions.

I am looking for the weight of the available free air versions that have the Fan / pulleys / belt /tower / and cooling shrouds removed.

I have seen Guesstimates of anywhere from 3 - 10 lbs.
