are they the chrome can shaped guys?
I thought they were more like 300 stock...
on the G3 your shock mount tops are just above the fender, the bottoms right on the swingarm, so they are longer, but 17" wheel, 2.5 tire and 2 inches of travel and an inch of clearance is a 350
This was a G3, these shocks I think were only 280s (maybe 320?). I had to significantly raise the shock mounts (maybe 2 inches, or 50mm - welded in extenders to mount bottoms higher), but it also had a much taller set of forks so the extra height was needed to level it out. Either way, 320 or 280 there was enough clearance even with bigger tires without raising it so I'm pretty sure you're totally good with 350s. here's a before and after comparison:
