Due to the the weak side wall I've been running mine at 45-47psi.
I think I have the rear shock preload at 10. Or was it 14?
I'm trying to find the sweet spot between shock preload and psi.

I did a spirited 560+ miles yesterday and all was well.
High speed sweepers at and above 90 were solid! First and second gear switchbacks are a tad quirky.
Anything regular, 5-10 over posted, all road conditions couldn't affect the solidity of the G-Max.
