Bike troubles, please help
I'm hoping that someone here can help me out with the issues im having with my bike (2006 GSXR 600...3,000 miles). It started running like garbage 2 weeks ago on a Wednesday.
It has a loss of a lot of power and sounds muffled and very growly, until about 6,000 to 8,000 RPM it takes off like a bat out of hell and starts to sound good again, more of a whine to the exhaust as it normal has and the power is back. Let off the throttle and you feel the loss of power again and real sluggish until you get back up to 6,000-8,000 RPM and it takes off again.
I have done a few things before this started acting up, none of which can I find a reason why it would make this happen. The Monday before it started happening I had changed the oil (Castrol Syntec 10W-40). Took it for a spin that night and the next day and everything felt fine. The day it started acting up I had hand washed it was the garden hose, took it for a spin that night after it dried and it had started running like garbage. The following day I ripped it apart to see if there was water anywhere in the air tubes or anything...nothing. I also recently switched from using regular gas to premium fuel and have been using seafoam (1/2 bottle per tank)in about every other tank for the last 6 tanks (up until this point I have stopped). I have fresh tank of gas in and it is still running like garbage, sounds terrible. Anyone have any suggestions what so ever???
