2011 GSXR 750 huge flat spot 4-7k rpms

There are individual pumps (not whole assemblies) on eBay and the like. If you go that route you may have better luck than I did.

It's possible/likely the janky, old-ass varnish that used to be gas in my tank is what killed the cheap-ass fuel pump I put on my 06, but it got the bike started a couple of times before it stopped working...

I ended up buying used assemblies off eBay and here. Now that I've actually ridden the bike at a track day (and stored it properly) hopefully it will keep working longer.

 

Yes.

 

Just remove the fuel pump and replace the filter, very easy job and dealer sells the filters pretty cheaply. I wish I had seen your post earlier because I had the same symptoms on my old 2012 750.

 

Me too....I have 2 OEM pumps on the way.....will be here tomorrow.

 

Welp, good news bad news....New/used fuel pump works great. Bike sounds great. Bad news is, i had the minty OEM blue gas tank sitting gas cap down on a moving blanket on the garage floor so gas wouldn't leak out of the fuel pump line while i was waiting for the new fuel pumps to arrive. Unfortunately the Vortex gas cap decided to leak and the gas ate an 8"x 8" area of paint off the tank. FML

 

That stinks. I didn’t realize gas would eat off factory paint?

 

The gas soaked the moving blanket that the tank was laying on, for 4-5 days. So the paint/tank was in contact with a gas soaked blanket basically for several days. Vortex V3 cap

 

i replace the screen yearly. fuel pumps are all rebuildable. since yours is working, it's most likely the screen

 

Not the first leaky vortex gas cap I've seen on a gsxr.

I replaced the fuel pump chasing a similar issue on my old gsxr, and got a fuel pump from fuelpumpfactory for $90 that dropped right in and worked perfectly. But didn't fix my problem LOL

 

Looks like a job for Rattle Can Man.

 

Know an artist ? I think I see something in there.

 

Hell, I've yet to see a Vortex cap tht DOESN'T leak lol. I just assume its a feature , not a defect at this point


Sorry about the paintwork BTW, bummer

 

I actually have some kustom canz triton blue, leftover from a tank that i painted.

 

Good as new.

 

It kinda resemebles the shape of africa, maybe put an africa sticker on top

 

I would have told people it's the Panigale R rare replica Suzuki built that year and you got to special from Japan from an importer.

<It could happen>

 

OUCH.
