I took the filter off and it was packed with surprises from Ethanol. The picture shows a small amount of what was actually there. I had tossed the filter and then decided to take a picture and retrieved it. I pulled the handlebar normal / reserve switch apart, cleaned the contact and verified that it was good. I followed the directions to the link above about the fuel pump. Disassembled and checked it all over. You'll want to mark the parts like I did, as they come apart so it'll go back together and be orientated right when the pump goes back on the bike. I cleaned the contacts while I had it apart. Found that the Fuel Pump Relay's bad too (Under the left scoop, front module).

Added LATE 12/20/2010" I went out and searched for a fuel filter. Nothing good came of that so I'll buy one from Yamaha tomorrow. I took the filter off and it was packed with surprises from Ethanol.

Added 12/21/2010 I picked up a fuel relay at CaptainKyle's this morning and a Real Fuel Filter at the dealer. I didn't think Kyle would be stocking fuel filters.. Wrong. When I got home, I installed the filter and the relay. The relay didn't help my condition and the hose I bought for the filter to the fuel pump was so stiff (USCG B-15 Ethanol Proof) I had to double clamp to get the leaks stopped...I charged the battery and ran the bike. It started and ran good until I tried a 4th and 5th gear roll on. It still breaks up at about 4,000 rpm. If I back off the throttle just a touch it will keep picking up speed without breaking up. Stage 1 with the needles dropped all the way and it's still running rich... Could be the drilled slides. I may have to JB Weld and re drill...
