So this is the filter from my Vee taken last summer. And no that is not mud puddle water, thats the result of back flushing the filter two or three times ( tray was perfectly clean before I started)
Bike had just under 70,000 km at that point.
One ride north to Inuvik NWT about 8500 km and the other to southern Utah about 8000 km.
On return from Utah I noticed the fuel pump was starting to sound quite noisy. .
Might have been that nice gas station in Eagle Alaska
I guess I'll never know for sure.
North of Whitehorse you seem to have a choice of regular gas or regular gas at most stations.
Did the fuel flow test. 110 ml in three cycles of the key, not good, should be around 350-400 ml.
My suspicion is it got contaminated on the ride north.
Each tank of fuel seemed to change the feel/vibration of the bike a bit.
It always ran and started well, just felt slightly rougher at times when at highway speed.
Was not noticeable on the ride south. The other Vee rider on the ride south has had no fuel filter issues.
Did the external fuel filter mod. last fall and now have a quiet pump again.
I am impressed that the filter allowed me another 8000 km before it became noticeable.
