Hey guys! So I've been searching all forums and cannot find an answer to this... Maybe its an obvious fix but I have no idea what's going on!!
Bought a used 2006 R6S with 2400 miles on it about a month ago, everything was perfect until I started smelling some gas... Looked under the tank and to my surprise (or not) there was a tiny gas leak coming from the Fuel Pump. Apparently the previous owner "sealed" the leak on the outside of what I think is the valve for the RETURN hose (coming from the Pressure Regulator) with Marine Tex or something similar... That obviously didn't work...
So I took out the pump and wanted to order just the part where the connectors go cuz I know the pump was working perfectly, however, they dont sell that part on its own (if anyone has it please let me know). And before throwing down 60$ to 150$ on a used pump (or 700$ for a new one) I thought I'd take a chance at sealing it myself, but this time from the inside and outside with "SEAL ALL" gas and oil resistant sealant. Everything fell into place perfectly, I am no mechanic but this bike is definitely easy to work on (so far) and I feel like "I stayed at a Holiday Inn Express last nite"
Now the seal is working great, no leaks as I put the pump back in the tank. Hooked everything back up great and went to start the bike. Now when I turn on the ignition I can hear the pump starting, the bike cranks, sputters a bit, but doesnt actually catch or fully start and my battery is dying on me. Checked the main fuel line and theres fuel on both sides. Took out the "return line" from the Pressure Regulator and I see its not shooting gas out when I turn on the ignition like it was when I originally took the pump out. That "return line" is dry right now. I went to a mechanic and he said that r6's and r1's are notorious for not starting up right away once you remove fuel lines but that as long as the main line has fuel on both ends I shouldnt worry about the regulator. He said its probably air in the lines and that I should keep starting it and cranking it until it finally runs as it needs to create enough fuel pressure inside and remove all the air in the (valves or chambers, not sure what the correct word is). He said it is somewhat similar to bleeding brakes, that by continuing to start it, it will remove the air bubbles from the fuel lines just like "bleeding" the fuel lines.
Now, is this true? I dont want to continue cranking it and possibly ruining my engine or having to buy another battery. Should I continue to do this? Does anyone have any recommendations? Has this happened to anyone before?
If you look at an intake diagram (Intake diagram 2) the "return line" I am talking about is part 46 (5SL-13972-00-00). Pressure Regulator is part 24 (5SL-13906-00-00). The part I sealed would be on Fuel Tank Diagram Part 21 (Fuel Pump) but since you cant see the under side of the fuel pump on the diagram, if you look at the "FOR CAL" section it is very similar to Part 34 (only the one on my bike is facing down to the floor so you can attach the line from the pressure regulator into the fuel pump).
