Real World Fuel Consumption?

[guest7]

I rang Terry Hobbs up once for advice about a girlfriend's (Harris) Bonneville. Man could he chat! What an interesting bloke he was, sadly missed by the classic community.

At Stafford one year a seller had a Trumpy engine with Hobbs' name stamped on it. One viewer said "what's so good about that?" and everyone who heard him turned around and looked at him. It was politely explained that Mr Hobbs was a bit of a good tuner and the bloke went away looking bemused and ashamed in equal measure.

Yup - never went into his shop in Plymouth unless you had a good amount of time to blather on - oh and not at all if you were offended by ripe language...

Had a treasure trove of parts in the "shed" - wonder what happened to all of them?

He and Monty his right hand man were a great couple of people - hopefully Monty still is.

One from memory:

1999 BMW F650

Worst: 41 mpg when ridden like a dispatch bike
Average: 69 mpg
Best: 94 mpg riding up Norway obeying the speed limits.

Andy,was that one of the carbed Funduros or the later FI ones?

Carbed. The FI ones are even better, you don't need to nurse the engine as much to get really good MPG's, which makes up for the stupid under seat fuel tank. It's a pity the water pump is so badly designed or I'd buy another tomorrow.

MuZ traveller, av 320km/14litres,
Vmoto scoot..125cc av 160km/5l thrashing the b*&^%$d

Best with Suzuki T500 Titan outfit 50-55 mpg
Worst ever: Sukuki 500 Titan outfit 22 mpg
Best on a T20 (250)Suzuki using every trick in the book including angel gearing downhill and slipstreaming semi's, app 120 mpg. (had to, no money, middle of nowhere, Guesstimated about 1/2 pint left when arrived in Brisbane)

Freind:  a club economy run back in the early 70's(winner) 84mpg two up on a T500 Titan. Club officials were present at fill up and refill over given distance. He was more surprised than the judges!!!

Whats all this litres per 100 km stuff.  I'm working late shifts and don't have the brain power.  Help, I'm coming over all European..........

[guest27]

I was having a giggle with a lass I know the other day - be nice to her she is (A) very tall, (B) an engineer and (C) works in a titanium machining company... (Andy did you ever sell that titanium you had?) Anyway she has given up converting litres to gallon or miles to Km and just does miles per 100L - seemed odd to me at first and then wholly sensible, even miles per litre would be more use than either Kms per 100L or MPG in the UK...

Enfield Bullet 500: 14L in but keep forgetting the odemeter reading by the time I fill up. Just fitted a 22L tank so that forgetfulness is set to get worse. Thrapped she returns in excess of 60MPG....

Steffan

[guest7]

Yeah, I do all my sums in miles per litre now. It makes sense, the pump says litres, the clock says miles. It's not hard to work it out 

Multiplying by 4.5 gives a rough figure for MPG, but after a while you start appreciating the meaning of the MPL figure itself.

MPL? Works better than I thought. 10 MPL is 45 MPG, 9 MPL 50 MPG. Without getting into the hideous decimal points that metric usually requires, the scale isn't that course. I can do 45/50 MPG calcs in my head to calculate range and wouldn't bother trying to use 47 MPG in the same way I'd aproximate 9.6 MPL down to 9.

It still takes an Imperial unit to make things work for numbers in your head.

L/100KM is just wrong, it doesn't tell you anything unless you want to ride 100 km and walk afterwards!

Andy

[Steffan]

I don't understand how MPG becomes L/100KM which in reality is ml/KM - wierd!! and not KML which would be easy on the Bullet and the Skorpion as the odemeter is in KM and the forecourt pump in in L ...still could do with a trip meter. Perhaps its time to fit the bicycle computer with the new handlebars

Andy

you want to read that back to yourself and try it again? 10mpl is 45mgp, 9mpl is 50mpg? fewer mpl makes more mpg? 

[guest295]

My old pushrof Honda 50 got 175mpg at 45mph. My GB gets about 60 @ 65, the Yamaha XT130 gets about 70 @65, the Toyota Starlet Turbo gets 40 with a roof rack on.

Sorry, can't read my own fag packet 

10 mpl is 45 mpg, 11 mpl is 50 mpg, 9 mpl is 40 mpg. One on the MPL scale is near enough 5 on the MPG.

[guest40]

Hey, Terry, what's the fuel prices like in NZ?

We are running around $A 1.57/litre Std unleaded

[guest27]

Now if I remember rightly there are AU$500 to the £....
