I did the same thing once. Bike ran better again after I siphoned out the 87. Very easy to siphon it out takes about 2-3 minutes. Replace with 93.
Use the 87 for your lawnmower or dump it in your car tank or whatever else uses 87 well.

 

thanks when i get home today im going to changes plugs and ride the hell out of it (the motorcycle) not the old lader if u were wondering

 

+1 on the screen name....best one I have seen yet.....as to your problem, maybe you drooled in your tank at last fill up and have stopped up your fuel filter

 

Coulda been high octane druel. happens ya know!

 

Anytime I get a problem like yours, where it points to gas although as others have said gas normally does not result in the problems you mention, my 1st fix is to add gas line antifreeze, a concentrated amount FI cleaner and go for a run to get rid of the old gas. If that doesn't work, you go from there
