Well i can confidently say that the gauge seems to be good as gold, i believe that the issue of the prongs not making good contact with the strip is the issue as it needs little resistance to be able to slide up and sown, i have been on the bike everyday since the fix and gone through 4 tanks and from barely reading the fuel level at all to now reading consistantly at all the levels i am happy with the results. it might just mean that the float needs to be disasembled and the prongs tweaked every so often .

Read the instructions for the Fuel Cap Remover/Installer in the attached pdf file. You will get the idea.

Yup, that a pretty dumb question. Take it to the dealer if you can't follow the simple instructions.

Thanx for the input. I wasnt sure if the sender came thru the top on its own, or the whole top had to be unscrewed, as the retainer wouldn,t budge.

My 07DX is currently on its third fuel guage, luckily both replacements came under warranty. My guage is still somewhat irratic for the last 1/4 tank, it is accurate enough I havent been stuck anywhere with an empty tank, yet.

I never got accurate fuel level readings, but my gauge is consistant(ly wrong!) showing me empty at 1/2 tank (refill at about 1.9 ~ 2.1 gal). I tried Seafoam and it made slight changes to my engine, it didn't help my fuel gauge. I'm beginning to think that the damn thing was designed by a frustrated fisherman!

08 NRS same problem

I have a 2008 NRS and my fuel gauge hasn't worked right since about the fourth tank of gas. I had it fixed under warranty and that lasted until a week after warranty ran out. I don't even bother looking at it anymore, just been using the trip meter. I called and was treated like I was stupid b/c this is a known issue with earlier model years. It is a known issue on my bike, which is the only one that matters to me. Is my fuel gauge the same as the one on earlier models? I haven't taken it apart yet, just asking before leaping.

p.s. Seafoam has worked great in all my stuff. gas engines 2/4 stroke, diesel, lawnmower, atv, tractor, truck, corvette, motorcycle all with no problems. This is the first fix I try when I have a fuel problem.

No.

The 2007 and newer VRSC models have “non-contact” ultrasonic fuel level sending units. These have a different (and well documented) problem. Here's a few other threads that discuss it:

Thread 1
Thread 2
Thread 3
Thread 4

I don’t think “Seafoam” or any other cleaner will make any difference on your ultrasonic sending unit since there’s nothing to clean.

I just installed a Rick's tank in my '04 and noticed alot of deposits on the resistive strip in the fuel sending unit. It was a dark brown film. I have only had 4 or 5 instances in which my bike showed empty when I knew it had fuel, happened at startup and the needle slowly rose to the correct reading. I cleaned the resistive element with carb/injector cleaner, real easy, I have a pic of the dirty vs clean resistive element and will post it later.

Here is a pic of the deposits I found on the resistive strip, left side is the way I found it and the right side after being cleaned. Used carb/choke cleaner, spray on and the residue wipes of real easy onto a clean rag, DO NOT use anything abrasive to clean this. When the resistive strip is clean, then shoot cleaner down the float where it rides up and down against the resistive strip, you can't get a rag in there to wipe so just move the float up and down to clean.

Tnx sammy worked great for me....my gauge did read empty all the time, pulled out the whole sending/pump unit

disconnected/unscrewed the resistive strip and cleaned it with carb.cleaner, brakecleaner and a very fine sanding paper ( very soft rubbing with that).

gauge now reads good, hope it will do that for al long time
