spingley Posted September 22, 2009 #1 Posted September 22, 2009 I used to ride an 03 VTX 1300 and it had a fuel pump, but on it people (myself included) would just remove it and replace the petcock to a style with no fuel pump (shut off diaphram in back) and bike ran fine because gravity would push gas to carb bowls anyways, hence less parts to break down while on the road. Has anyone ever done this on the RSV? It seems doable to me as the tank is above the carbs, cannot think of a reason it would not work, but sometimes I just cannot think.
Kregerdoodle Posted September 22, 2009 #2 Posted September 22, 2009 I have heard of a few doing that just to get it back home, it will run, but you have to take it easy on the throtle as the gravity can`t keep up with the demand.... if your fuel pump is bad, Ponch put a (can`t think of the name) fuel pump on his for around $60.00 works great and better then $200.00 from yamy...you can contact Ponch for all the info if he doesn`t jump on this..

There are others with more expert knowledge of the bike than I, however, this is what I remember being told to me when my fuel pump died and the bike wouldn't run.. You need a fuel pump for the RSV.. The rear cylinders are gravity fed whilst the front two are pump fed. If you have NO pump, you can't get fuel to the front cylinders and they will not fire. This was the fault with my bike this summer.. (one of the faults)..
pegscraper Posted September 23, 2009 #4 Posted September 23, 2009 The rear cylinders are gravity fed whilst the front two are pump fed. Umm, this makes absolutely no sense. There is only one fuel line running into the carburetor pack, and it feeds all four carburetors. All four carbs are fed by the fuel pump.
wizard Posted September 23, 2009 #5 Posted September 23, 2009 It can be done. I ran without a fuel pump when it completly failed. Just pull the fuel line from the filter and run it directly to the fuel inlet on the right side of the bike.
BigBoyinMS Posted September 23, 2009 #6 Posted September 23, 2009 It's a common mod on the Road Stars but you have to open up the tank vent... and sometimes vent the cap... and sometimes replace the factory needle valve with a higher flow one from a Suzuki... and sometimes put the pump back on. LoL Actually, add the needle valve and vent the tank and usually it's good to go. The 4 needle valves may be the biggest issue on the Royals.
Ponch Posted September 23, 2009 #7 Posted September 23, 2009 If interrested in an after market pump, check this thread. I've got about 5000 miles on it now. [ame=http://www.venturerider.org/forum/showthread.php?t=40359]Can't Keep bike running? ANY HELP - VentureRider.Org[/ame] Post #13

All four carbs are fed by the fuel pump. As I mentioned I'm no expert but this is how it was explained to me when my fuel pump died on a road trip in PA and the mech explained it to me. No fuel to the front until a new fuel pump was installed.. That's all I know..

You just have to mount the new pump on a plate or secure it otherwise and plumb the pump similar as shown. I like it because you can buy these pumps at most auto parts stores on the road, while I'll bet that no Yammi dealer stocks one.

You bet the don't.. luckily for me, the dealer in State College PA without hesitation took the pump off the show floor '09 and installed it in my bike.. gotta like that!! awesome people. Next time in PA I shall make a purpose visit there to thank them again.. nice!!
