2002 R6 with 10k miles sat for about a year with gas in it. Now it idles rough and maxes out at around 90mph in 6th. I figure the carbs need to be cleaned so I'm doing that, along with replacing the fuel filter and air filter...maybe the spark plugs too.
1. What's the best method to clean the carbs? I'm a little confused...in doing research, some people mention that one doesn't have to completely take apart the carbs. Others say you have to take them completely apart and clean or let soak overnight. How should I proceed? This is where I'm at now:
2. Does one method of cleaning not require to sync the carbs again?
3. I noticed some hard deposits in the hole where the carbs attach to the engine, as seen in the image below. Should I do anything about this?
4. Any other suggestions on maintenance I should do? Already flushed radiator, changed oil, flushed brake lines, lubed chain, new brake pads.
