But i had a k before my 91 rt, never problem, could have 1 litre left, never notice anything.
When i got my first k 75c 86 mod, i been told by the seller that this bike not have the fueltank whith the gaspumpinlet mounted too long in front of the tank.
My problem today is when you give more throttle fast, by xample passing a car, the fuel is forced too the rear of the tank, and the injectors must have 3,2 bar fuelpressure too contain the engine power.
But its not a problem when i have a constant speed at 50 mph, because the gas is in all of the bottom of the tank.
My english is maybee not good, but do you anderstend what i try too explaine??
My friend took a look in the tank on my 86 mod some years ago, by opening fillercap, he said, "yes you got the right gastank" And i remember a time ago, that i heard about this problem before.
Offcourse i should fill it up when the red warning light comes on, aprox 1 gallon. (4 litres) but i often drive 300-350 km nonstop here in norway, and somethimes long between gaspumps. I really like too drive long distances
But i could also been wrong about this problem
, but will check whith an Bmw dealer about it tomorrow.
I notice from the bmw dealer now, that its different type off fulepump up too mod 93, from 93 onwards is another type of fuelpump.
Thanks for your reply
