Hi. I recently picked up a 2001 honda cbr 600 f4i and it was running fine for a couple days till yesterday. I was riding and it started to run weird with less power and acceleration as well as sounding like a putter with pops coming from the exhaust as well. There is also an issue where the main fuse will blow if I roll it around without turning it off and taking the key out. Any ideas on how to fix it or what to look at for other issues?

 

If you're blowing a 30A fuse with the engine off but ignition on, you have a short somewhere. Pull the rest of the fuses and use a multimeter to see where the short is.
