This past weekend I got to know the FJR a bit. I changed oil and filter. Found the thing has a K&N air filter and it was gunked up. I'm not a K&N air filter fan, so ended up calling 3 different Yamaha dealers and none had a stock A/F in stock. Neither offered to order one up, so I bought one from the inter-web. I removed the aftermarket lowering links and went back to the stock dogbones. Put the center stand back on and while there, the linkage bearings and related parts were inspected and greased. Put a stock kickstand back on as PO had bent the one that was on it, due to now removed lowering links.
PO stated ( and I experienced ) CEL light would come on at steady throttle above 50mph. PO said it always did that and he just put tape over the CEL. He read it was due to the PCiii and the O2 sensor being disconnected. So I got out the laptop and usb cord to find no map installed. Not a zero map... no map...nothing. So I downloaded the stock map with O2 unplugged. No CEL and runs quite a bit better. A good day but just started to rain before bath time on it.
