Hey I can use some advice my car is in the garage so I have been riding my monster to and from work for the past week and it has been raining pretty heavy all week , Now she seems sluggish especially over 6000 rpm she sounds like she is suffocating . She is a 2012 with termi slip ons,ecu and new air intake any 2 cents would be much appreciated (also small oil leak around oil filter but doubt it is connected )

sounds like you might be running on a single cylinder. Fire up the bike, give it just a min to warm up and you should be able to senses the same amount of heat from both headers as they exit the head. Just hold your hand near it and feel the radiant heat - don't touch!
If one cylinder isn't firing  that header won't be worm 
			
			
			
				Maybe water in the fuel?  Can happen if your water drain on the tank gets clogged.

Wouldnt riding on one cylinder be a drastic change? it is more of a slight decrease and muffled sound that I notice, but doubt noone else would if they hopped on my bike
			
 
			
			
				try install baffles. [leo] runs much better with them

Your Monster will actually run amazingly smooth on one cylinder, it will just loose idle speed and be extremely sluggish.  Definitely check for fuel contamination if all was well until after a rain storm.  2012?  Still under warranty?  Of course fuel contamination would not be covered unless caused by a manufacturer's defect.

				Checked headers both nice and warm, Will be replacing the gas tomorrow and will see if that helps

				TS, is it like running on low gear? bike decelerates instantly when you are not accelerating?
I think all monsters have this illness.
