I was having same problem with fuel gauge, it would do the intial sweep then straight to empty. I ordered sender unit form partizilla $75 plus shipping. I installed it and still have e same problem. I'm thinking that it's the solid state board that all the electronics plus into... The price is ridiculous, like $600, so I guess I will keep riding with a brand new sender unit and an inoperable gauge. I will just switch to reserve when it runs out....
Sanes7,last time i checked the instrument cluster was closer to $750-800 then $600.
Update,just looked it up,its $728 list & $588 wholesale not inc shipping for the inst cluster so you were right on the money/LOL!!
Anyway,i have a spare instrument cluster & everything works fine (speedometer/fuel gauge/signal arrows,etc) accept for the clock that stopped working.
If you or anyone else here in RSC is interested i will let it go for the $150 i paid for it not inc shipping to your residence.
I also have a brand new in the box fuel sending unit,it lists for $105 & wholesales for $71 not inc shipping & i paid $81 for it inc shipping.
I'd let the fuel sender go for $50 not inc shipping to your residence.
PM me if interested in any of the parts.
