CB750 MPG

<< < (2/3) > >>

steff750:
 ;) i must ride like a pussy my four cb750 k0's give just over fifty to the gallon
my sidecar unit is a bit thirsty but im sure that is doing well over forty to the gallon
i rarely go over seventy and prefer cruising at fifty to sixty and always go for long runs

Spitfire:
On a day out touring around Wales I got about 48 mpg from my CB750F1, mind you I am Mr Slow these days and stick to the speed limits.

Cheers

Both my CB750 (K2, US Spec) and CB500/4 (K1, UK Spec) return around 43 mpg with normal use. I try, however to avoid town riding (not too difficult in rural Norfolk). On the CB500 I change up at 6,000 rpm as a rule and cruise at 5,000 - 5,500 rpm. Similar speeds are adopted similar with the CB750, although engine rpm is obviously lower.

Erling:
In the day I reckoned some 15 km/litre. About 40 miles  to the gallon?
No speedo connected  due to a 250mm Fontana 4 leading shoe drum bake conversion.
Distance covered between gas stations on the German motorways on week end trips to spectate at Moto GPs of the day gave an idea.
And the CB 750 used more than than the same capacity BMW and had only 18 litres to the 24 of the BMW!
In a days riding I came further on the 50 BHP BMW than the faster Honda!
Speed difference minimised after a few years. The BMW dropped an exhaust valve up through Germany from Italy.
More or less outside a BMW dealer. It was just to order a 67 BHP 90S engine!
And off we went even in the first place with the original 32mm vacuum carbs to the 38mm Dell Orto.

MarkCR750:
Hi Erling you mean that you fitted the engine immediately and continued your journey?, if I understood you correctly then you deserve great respect!
