87 Octane

I have been running the low grade 87 octane and just got the manual and it says I should use 90. Any performance or starting issues using the cheap stuff?

on 87 the piston will crack on calif. crap gas. it takes about 50 hrs but it will crack. ive seen kawi 450's do it and rmz's

i always used shell 93 on my yz450... still use it on my yz250 smoker

what about running any supreme gas offered at a typical gas station? Any comments?

I ran 93 yesterday and I swear it was easier to start.

i live in sweden and we have shell-V power 102 octane, my bike goes very nice on that fuel....
