The great fuel injected Roadie 4 Years, 8 Months ago  
Since the great debate a little over a year ago over the ‘lean’ question on the FI 08’ and up bikes I thought I would make a few notes about Yamaha’s, what I consider really good, ECU and associated systems, and what I’ve noticed on the Innovate AFR.

I ridden the bike with and without a BAK, and with the BAK it does tends to run leaner (up in the .16 range, but only in some conditions), the bike still runs around 47.6 at cruise either way. Overall the ECU seems to do a great job in adjusting to various mods in the exhaust, and air intake.

The injection duration takes it signal from the TPS, crank position, intake pressure, air temp, speed sensor, atmospheric pressure, and 02 sensors.
The injection time through the crank position. Now that is a little more complicated than a carb, BUT, My bike has only coughed once during the two years I’ve had it.
Why it coughed that once, I have no idea. It could have been a temporary failure of the CPS, which I think it probably was, however it didn’t even set a code.

Now…just judging from what I read on the Harley forums, and putting their troubles up against a Roadstar, Yamaha wins hand down with their FI on the Roadie.

Now there ain’t much point to this post except that at the outset, I was a little leery of owning a fuel injected bike, but so far I am pleased with the Yamaha ECU.

How long before we start having problems with sensors is anybody’s guess, but sensors have proven out over the years to have long life. My 1997 Lincoln Town Car has 146000 miles on all the sensors.

Most of the problems on the forum seem carb related. Thank God, we can mod these bikes with different pipes and air intake and it has little affect on the ECU, and we don’t have to buy hundreds of dollars worth of after market fuel controllers to get it to run right either.
