The latest version for the sonic fix was to incorporate a float in the tube so the sensor would read the level better. You have that one. Nothing since that. Now, there have been a couple that found out by adding Seafoam to the fuel, it seems to do something to make it work again. Why, I don't have a good reason for this since it's not like the older fuel level resistance strips that would gum up. Some kind of chemical voodoo shit I'm not smart enough to understand for these sonic sensing units. Try this first before buying another sender that will likely have the same issue down the road.
I’m sure you get a lot of different opinion. Just curious how many miles can I expect to ride before I should refuel?
100 start lookin for a station after that.
100 start lookin for a station after that. For the early 3.7 tank yea, that's about right -
For the 5 gallon tanks you can go 140 - 145, about halfway between E and 1/4 tank, but that's riding at lower speeds and taking it really easy on the highway. Once you start doing jackrabbit starts and 75+ mph the gas gets gobbled up faster, often I'll refuel at 100 - 120 miles in normal operation just to be safe but so far ( knock on wood ) my gas gauge has been very reliable and spot on as far as not fooling me that I had more fuel left than what the odometer says - just err on the side of caution it's very dangerous to run it outta gas and pushing a 640 lb bike out of traffic and on to the gas station is really no fun !
I used scotch bright pad and seafoam. My early sender works most of the time. It likes to stop some times right after I fuel up it reads empty. Then a few miles later it starks working again. I think the only reason it keeps working is because I have a brand new sender in a box waiting to be installed. They have a mind of there own.
