Ummmm now what

So I've been a member here for a while but have yet to make a post. Here's my issue I bough a brand new 2010 fe450 from day one it has coughed and sputtered vie have had it remapped new fmf slip on exhaust (can only) wrapped the exhaust piping in header tape put heat reflective tape on the fuel tank changed the spark plug cap adjusted the idle about 20 different times still no luck. The bike still wants to chug and cough and sputter at lower rpms off and on the throttle

The last couple of rides the bike has actualy left me stranded due to the awesome fuel pump that decided to get heat stroke. The pump was replaced buy the dealer under warranty yesterday was the first chance I got to ride since I replaced the fuel pump I thought it was all good but nope still coughs and sputters. Wide open in the upper mid to top end it will screen but off idle to mid range off and on hahahah total poop. any ideahs? Maybe I'm missing somthing I bought something new to avoid issues like this everywhere I read all the reviews had nothing but good things to say about these bikes and I get the lemon go figure any input will be appreciated thanks for your time

Spark plug?? We have seen a few with cracked insulators. What does your dealer have to say about the problem?

Re: Ummmm now what

As far as my dealer goes the first time I dropped off the bike for the issue i had changed the exhaust they said it ran bad cause I modified it and needed the competition map which they charged me to put in but still no luck second time I broughtght it back left it there 3 weeks to get it to replacate the fuel pump issue and they did. The fuel pump was replaced under warranty they did put engine ice in the bike with out asking me said it should keep it cooler and that they charged me for the bike sat for a while due to work and I go to ride it yesterday and still runs like crap it's a 3 hour drive to the dealer and I'm not getting anywhere needless to sa I'm not too happy

You are not on a lemon. Get that thought out of your head

Like Berger says, Spark Plug?
Not too much oil in the air filter?
Check Battery Terminals are tight. That seems to happen a bit on here.
Check for white foriegn stuff in the tank. That has happened on a few new ones. Clogs the Fuel filter/pump.
Check you have the correct amount of oil in the engine. Make sure there is not too much in there.
Is the EFI Light flashing any codes?
What else have you checked?
Check the Throttle Position Sensor (TPS) on the Throttle Body is not loose or cracked.
Is the Fuel old?
You may have a clogged Fuel Injector. If you eventually find it is that run a ProFill Fuel Filter
Does it do the same thing on all 3 map settings of the map Switch?
The delaer could have kinked the Fuel line when they installed the new Fuel Pump too.

Take it back to the dealer they should fix it.

I want the two filters that are on the ProFill website. But the shop is closed. Does anyone know where to get similar filters that are very good??

new fuel
Spark plug is new
Battery checked before every ride
Tank has been checked several times fuel pump has been replaced
No efi light
I've have tried more and less filter oil still no difference
I do not have a map switch

How can I check the fuel injector?
And how can. Check the tps?

You would need to get the dealer to check the Fuel Injector or take it to an EFI Shop that can ultrasonically clean it and flow test it.
The Dealer needs to test the TPS. He can tell it is reading the correct voltage on the wiper wire at closed throttle and open throttle via his computer that he hooks up. I think it works this way, The Khein EFI system learns 0% on the Throttle body, it is manually set by moving the TPS sensor and looking for 0.6Volts between ECU Signal Ground (Black Wire) and the TPS Wiper (Yellow Wire).
TPS is the main thing the EFI reads to work out how much fuel to squirt in the engine. TPS and RPM are the main two things it reads actually.
You will get there just need the correct person looking at the bike. Hopefully one of the US guys on here will chime in and suggest a good dealer or some other helpful advise.
