[QUOTE="PopCycl, post: 17460, member: 533"] I used to own a Honda VTX 1800 that was fuel injected also. I experienced a sudden, severe drop in MPGs and had a real hard time getting Honda to look into it. The bike was running fine with just a small loss of power but the MPGs dropped from 35-37 to 25-23. After finally finding a dealer willing to take a look they found the waxing valve was broken. I do not know for certain if the FJR uses a waxing valve or not. Basically it is used to increase/decrease the fuel for cold engine idle. My valve broke in the "cold" position where it continued to let extra fuel in during all operating temps. Once this was fixed my MPGs rose back up to 35-37. Pop by the way, my 05 w/ 11,000 miles get 40 in the city and 50 on the Interstate. [/QUOTE]
