Wondering if anyone has had this problem in the past? Riding an 06' RG. My fuel gauge sticks on full, you tap the guage and it drops to lower level and then pops back up to full, and then just continues the process. Once the level hits about 1/4 of a tank, then the needle seems to work fine. The low level light comes on whenever it wants? I haven't gotten into the book to trouble shoot yet. Through others experience I am wondering if it is a guage problem or a sending unit issue?
