Just curious, has anyone had bad experiences runnind a low octane(like 87) fuel in their yzf? I'm not planning on cheaping out on fuel or anything, but I may have accidentally put 87 octane in mine, and was wondering if that could cause the probs I had with my bike acting like it was locking up? I have done everything. Checked the timing, head/valves, cylinder/piston, crank, flywheel & woodruff key, clutch, tranny, etc. and everything is perfect, so I'm really just guessing & grasping at straws now. Anybody?
