Here's another one for you all.
I was out on another nice ride out again today and managed to cover a fair bit of ground.
I filled the tank up before I left and managed to get down to the reserve on the way home.
Now apparently I managed to do 140 miles before it started to chug and needed to be put onto reserve.
How many miles do you folks get out of your Superdreams from full tank to reserve?
Also and I've not done this yet but has anyone ever run their bike out of fuel to test how many miles they will do on reserve?

Phil I recently drained my tank and specifically drained main tap then on reserve - I got just over half a 5 litre can from the reserve drain, about 2.5 litres
Tank holds - 14 L (3.1 Gallons)
Based on full tank you would have used you probably used 11 litres which is 2.5 gallons which is about 57 to the gallon
I make the reserve 30 miles from those calculations
Be interesting what feedback of real life experiences in comparison with the theory above

Yea that sounds about right then. not bad really considering there were about 30 motorway miles in there as well as A and B roads. |

When I fill my tank I get between 118 to 122 miles on the same roads on my daily commute to work with town riding and faster dual carriageway roads in equal measure before getting to reserve 😀

I'm about the same. My commute is 15 miles each way so if I use the bike for all four shifts each week then 30 x 4 = 120 miles... I then fill up again as I have needed the reserve a couple times to get me home after my last shift.
I'll note the exact mileage next time I fill up and see exactly what I'm getting

My 400 is about the same, I get to around 120 then start looking for a garage.

I'm not sure on the miles to a tank but I've measured mpg a few times and mine gets around 50mpg from what I remember, I filled mine to the bottom of the filler spout and zeroed the trip meter.
You then fill up to the same spot next time making a note of the milage on the clock and how many letres it takes to fill to the same as before. You then divide the number of miles by the amount of letres then multiply that by 4.54 which converts that to gallons.

140 is not bad. I ride mostly around town (but often on fast 40-50 mph roads without too many traffic lights) and I have to put the bike on reserve at around 190-200 kilometres (I guess it is 120-125 miles). A friend has got a same spec 400n German edition, and he says, he's getting around 3 l/100 km (just shy of 94MPG) with Iridium plugs. I don't know, if I should believe him as this is a rather steep figure, and I have never seen a report of a 400n getting any better, than 50-60MPG. I'm not too heavy (11.3 stones) but I'm tall and I also carry most of the times a rather hefty photo bag weighing 2.6 stones

Not sure what I'm getting from my SD 250 it cost around a tenner when tank has done 100 miles to fill up with unleaded at £1.11 per ltr seems about right to me

No way a 400 would get 94MPG- that's moped territory that? Even if it's a low power version (most German 400's were)...

94 mpg is a massive stretch I reckon 55mpg give or take 5 is closer to the mark, a twin carb m,cycle carrying a bit of timber some 30 years old plus , I don't think 55 is to bad 😀

Yes, that's why I have taken this info with a pinch of salt... By the way, what gives the higher/lower versions? Different crankshaft, jets? Is it easy to make a weak German Super(ish)Dream into a proper one?

Hm, cmsnl lists the restricted version with a different crankshaft, than the full power one. But it also says, one is superseeded by the other. Go figure  |

Surprising the only difference in the low power versions was the camshaft?
Honda strangled the engine big time by altering the cam profiles and timing. I think nearly 3 mm less valve lift inlet and exhaust and the valve opening time was drastically reduced as well. Both inlet and exhaust valves operating about 40 degrees less and little or no overlap at all between inlet and exhaust.
But apart from that the engines were identical- same carburation and same timing. Very easy to unleash the proper design power by just changing the camshaft....

So two questions really - a) if you unleash the hidden horses will the fuel economy be changed? and b) is there an easy way of telling, which camshaft do I have? Thanks! |
