I want to get the flywheel lightend, and have a few questions about it.
It has 3 rivets in it, when i drill these out will it seperate the ring/gear from the flywheel?
Also my engine has the 6j2 pistons in it, as I have read these are not the best.
How long will these last? Engine has not much hours...

Engine will be ported and 90hp carbs.
