You wanna loose weight? The 1st thing is try to loose rotating mass, I already have lost 20 gram with the clutch and brakedisc and that is a lot that close to the source. 1 gram on the clutch is like 5 gram at the wheels
Correct,
I broke some titanium screws for engine mounting.
Steel screws never broke off for engine mounting purpose. They just wear out at the head tip.
