    Hi,

    how many miles do you do before filling up? I can't remember the tank range from when I had my last 650, today I got 179 miles before I bottled it and put some petrol in. As there is no 'reserve' or fuel tap how far can I go before I have to start pushing :eekicon:

    I usually start looking for a petrol station around the 180 mile mark. If I know the area, and know where the petrol stations are, I've run the bike down to the needle on the stop of the petrol guage before filling up. In unknown areas I'm a bit more careful. ;)

    It really boils down to how heavy handed you are with the throttle.


    Edit: By the way, how much fuel did you get in the tank after your 179 miles?

    I'm with Lutin, and start looking at around 160 miles if I'm"away from home". Can squeeze in anything from £18-20 worth. When I first got the bike that was about £12-14 ...... :(

    15.69 litres which I worked out is 51.34mpg, that sounds about right I suppose?

    Yeah, that doesn't sound too bad. Have had mid 50's out of mine before now - and a lot less as well. ;)

    The tank holds 19.5+ litres from almost completely empty so if filling at 180 and 16 litres you have easily got 30+ miles in there still. I used to run mine to 220-230 before I got worried. But it did usually take 18-19 litres.

    But don't blame me if you run out while experimenting.

    Looking forward to adding something to this thread once the 650 is on the road next month, but before then I'd like to add this:-

    Running the @ last year into, round and out of Euro land with Jim, Fiona & Hudders, I averaged 59mpg over the 2850 miles I covered with the @ fully loaded for bear! Given that the 650 Alp is slightly lighter and has approx 100cc less engine capacity, I'd expect the Alp to better this figure and subsequently be better than the figures you guy's have experienced with your rides. I understand that everyone rides differently, and that all machines have different set ups etc etc etc, thus we all experience different returns from our rides, mpg wise, but I would have expected a generally higher mpg figure than you guys have described.

    Time, miles and smiles will give me the answers . . . . . . so bring on British Summer Time :beer: :lol: :lol: :lol:

    Steve, when I first got my 650 way back in 2005(!) It used to do around 47mpg (crap) irrespective on how it was ridden, from brim I ran it out (deliberately) just short of 200 miles.

    When the needle is at the bottom of the red, I recall there is about 25-30 miles left, about 10 miles when the needle is on the top corner of the 'E' until you are pushing....

    125mains & a couple of holes in the airbox & you should quite easily get 250+ from a tank & nearer 60mpg.
    Bloody Euro emissions bollox.

    Cheers Phil.

    I have read your old topics on airbox conversion and main jet changes. The one that still grabs my attention though, and it's nowt to do with mpg, is that expansion box thingy under the engine! You cropped one I seem to remember, by taking the box out of the exhaust system all together and just plating up the side. Did you see this as an easier option to just loping the box off and creating a link pipe from the headers to the silencer?

    Just thinking out loud - I find it helps to drown out the other voices in my head :eekicon: :thumbsupanim:

    Hi Steve, yes after pondering the options, I figured it would be easier (cheaper!) To leave the run of the exhaust 'as is'.
    Sure getting a section chopped out & new section welded in place would have been a neater, more professional approach, it would involve dropping the bike or headers off at an exhaust fab place and prob end up costing £££

    This way, I can do the chopping, a local metalworkers/fab shop will blob a new plate on for beer money ;)

    The soon to be oil covered alloy storage box bolted to the centre stand was a later addition, home made & holds a small compressor, tyre valves, gloves & stuff.

    I have Bobs old TA650, when I brought it off him it had road tyres on and would do 55 to 60 mpg depending on riding motorways or lanes, no proper off road. Changed to Avon Gripsters it then returned 50 to 55 mpg. I changed the silencer to one off a Benelli, straight through but quiet, still with standard front with sub chamber, now back to 55 to 60 mpg.
    I have done 180 miles on a tank before I chickened out, about 90 to 100 miles before the gauge moves then refill at about 150 miles.

    Need to remember to order some 125 main jets when I next put an order into David Silver's. Been meaning to do it for ages now.

    If you want genuine jets at aftermarket prices try Allens performance ;)

    DO NOT go down the aftermarket jet route, even if they 'claim' to be oe replacement or whatever....

    Yes Phil, I had read somewhere recently about after market carb jets and their pitfalls.

    I have road tyres on this one as well Dave, must be something about the Alps I buy :)

    I'm not going to change them until they wear out though, that way it stops me taking it off-road, Alps are fine off-road but I'm not getting into the crashbars, sumpguard, etc etc scenario again, I'll use the KTM if I want to do that.
