Avs2 650 tuning on a 340

Without checking with a piston stop, you know absolutely nothing. The purpose of that is to check that the balancer is in phase with "everything else". If you're not willing to do something as simple as that, we may as well end these shenanigans right now, because if you won't listen and do that, then everything else might be wrong.

I'm not sure what you mean here. I'm trying to do everything I can that is being recommended to me. I'm still learning. I never said I won't use a piston stop. Just dont have 1 at the moment.
I'll be looking into checking over the timing this week hopfully and will report back. Had to order it so it will take a few days
