Yup sure is correct I once had a GSR sigma 1983 that had suuch a heavy fly wheel that
when you let the cluch out on idle you could not stall it it just chugged a chugged
along for a bit.
I drove a ex missu's sigma not a gsr that had a very much lighter flywheel and it was
very easy to stall and was gerky as hell.
I taught a few female friends to drive in my sigma and they all begged me to let them
do there test in it as it was un stallable and they all passed the first time.
Just my 2 cents worth anyways.
