Fuel pump going out?

Hi, I have a 2011 FS 570 and it has never started easy. usually (3-4) 5 second holds to get it going. Well now along side of the hard starts its also not wanting to re start after a 20+ minute ride. I commute with this thing and the first year it had no issues starting back up after the 20 minute commute, now it coughs starts, runs for 2 seconds then falls on its face and dies. I then have to wait 5-15 minutes to get it to re start.


Its completely stock, I just ripped out the smog stuff in an attempt to see if that was causing the problem.


Any help would be great! The bike has about 2900 miles on it. I've had it for about 11 months

Re: Fuel pump going out?

I believe your fuel pump is your issue, after MUCH research I will give you my take on all the 70 degree fuel pump problems. First of all I believe most of the problems are not filter related, I believe they are directly related to clearance issues inside the pump however this is only my best guess... Now for the good part I have successfully cured a pump before it completely stopped working! I can only tell you what worked for me the one time I had to try it. 1. Remove pump from tank and drain all fuel 2.check to see if pump gets hot in your hand while it runs (if it does it's going out, the faster it gets hot the worse your problem. The way I checked mine was to hook it up to a 1500ma 12v wall charger, you could just hook it directly to your battery. The pump should not get too hot to hold, should not drop rpm's or stall if disconnected and reconnected, if it is working properly, at most it should get slightly warm. Here is how I fixed mine: follow steps1&2 then 3.drop a few drops of WD40 in each end of pump 4.connect to 12v, occasionally switch + ~ in order to run pump forward and reverse. Repeat this process while holding pump submerged in water. 5. When pump runs with out heating up, slowing or stalling you have been successful. This process removed the friction causing obstuction in my pump. Hopefully this will work for some of you saving you some $$$$ as well as getting you back on the trail. One more thing, I believe when the pump starts to go out it reduces the amount of fuel going to the engine WHICH THE FI COMPUTER READS AS A LEAN CONDITION AND COMPENSATES FOR !!! Resulting in engine overheating , sort of a visious cycle (no pun intended) anyway that's my take on things, my bike is running with NO problems.

Re: Fuel pump going out?

just had a fuel pump issue... i believe because i had low fuel that the pump had somehow lost its prime, i took it out and submerged it in fuel and tried it with normal and reversed polarity. it just blew out a couple of small air bubbles at first, but after doing this a few times it began working again! not sure if it was debris related or had lost its prime. when i removed the pump it had also come out of its housing, not sure how but this may have caused it to suck air hence lose its prime..

Re: Fuel pump going out?

Weird, I ended up replacing it with the CA cycle works pump, first time i got it back together it wouldnt prime. The ground was just slightly up off the terminal when i put it back in. so i got it back in there and zip tied it pretty decent. Now it primes and wont start lol....

About to pick up walking. My legs have never left me stranded before....

Re: Fuel pump going out?

Well after about 20+ tries of getting the system to prime and killing off my battery (ended up buying a 5Ah TurnTech <3) It works. Its all done and I didn't have to buy anything different then what came with the kit. If anyone runs into this and wants any insight/having trouble figuring something up P/M me!

And the 5Ah TurnTech starts my bike better than the Yuasa battery ever did.
