CB750 mpg
MrDavo:
I can't find the recent previous thread on this (or maybe, as happens on here, it was a diversion on a thread about something else entirely) but, for the record, after careful measurement I am pleased to find I am doing 37mpg, I guestimated it to be far worse after nearly running out of petrol the other week.
I'm sure there will be gentle riders who get more, and Earnest Thrasher who will get much less, but my K1 is bog standard inside, most moving parts subject to wear have only a few hundred miles on them, and the carbs were synched professionally, so a pretty good yardstick.
Unfortunately I am too stupid to work out how to set up a poll (if you can with this forum software) to see what you all get. I always treat published road test figures with contempt (don't want to upset the advertisers etc), and anyway most figures on the 'net are in US gallons which are different.
Skoti:
Have you ever renewed the carb needle jets? :o
MrDavo:
Yes. It was a pig to start when I got it so I changed everything. In the end it all came down to needing a carb synch.
Skoti:
I only ask because my F1 also had poor fuel consumption of around 35mpg when I first bought it.
After a service and tune up including carb synch the fuel consumption problem was still the same.
Met a bloke on a F1 at the Moto Piston rally in Santander and he told me to renew the needle jets with genuine Honda items. He said they would need renewed about every 12,000 to 15,000 miles to maintain decent fuel economy.
He was correct, on a recent 3,000 mile round trip to Ireland I averaged 52mpg. :)
