I'm a proud '07 R1 owner and a bit of a technoGeek. I ordered a Service Manual the day I signed the contract thinking I could study up until my bike arrived. Didn't work out that way but now I'm getting into it "well and truly." For background: I was a Yamaha (Ducati and Suzuki) wrench every season from 1979 to 1990 (just summers for the last few years while in Engineering school). I'm quite happy to read one of these manuals cover-to-cover.
Looking at all the postings describing the FBW lag at 5500 RPM: While I only have 35 miles on mine so far (
its snowy today, too
) and haven't actually experienced it yet, I do believe its a real problem. I have a few ideas about dealing with it.
This behavior reminds me of the way the left over models in '80s behaved "back in the day" when the fuel stabilizer caused the famous “green goo.” The results of the carb tuning I did on hundreds of them was very dramatic. Having hundreds (maybe thousands) of hours tuning carbs with the exhaust gas analyzer, I wouldn't be surprised if old fashioned tuning helps allot. Its, at least, a good place to start. The possibility needs to be eliminated before moving on.
Carefully searching through the service manual, first by hand and then in PDF, I found 6 references to “CO Adjustment” and one specifically says 'Execute the CO adjustment mode and set the exhaust gas volume of the faulty cylinder to “0”.' (See page 8-59) However, I haven't seen anything on how to "Execute the CO adjustment mode”. Suspiciously, when I picked up my service manual, it had the plastic wrapper torn off. Maybe that's where those instructions are!
So, does anybody out there know how to enter CO Adjustment mode on the 2007 R1? Maybe an "anonymous coward" from some mysterious Yamaha shop that can “clue us in” without falling victim to reprisals? ***Insert Conspiracy Theory Here***
PS: I lost about 90% of my sense of smell back when I did all that carb cleaning. Recently its recovered to about 75% to 80%. Hey, it has its advantages; just ask the ladies!
