Got time to tackle an intermittent problem? Bike runs great then a few miles into a ride loses power. Bike changes tone (sounds lazy) and will barely hold 55 mph at full throttle, then it'll kick back in full power for a few minutes and then go back out. Annoying as hell. Feels to me like it's either losing a coil or fuel flow...but I ain't the master bike tech. Think it might be vacuum related...not sure how to check that though. Stupid Suzuki vacuum petcock. Hate that freaking thing.
