Title: How much does a GYTR pipe affect it w/o a fuel commander?
Post by: Livingmylife93 on July 16, 2008, 08:47:12 PM
I have a GYTR pipe, just got the 700, but it runs kinda rough. It backfires alot, and doesnt idle for very long, but i havent really completely let it warm up yet either. But my main question is does having the GYTR and not having a fuel commander of any sort other than stock really f :mad: ck it up?

Clockwise or Counterclockwise to turn the idle up?

ya your running really lean with no controller. The bike will not run right no matter what you do or turn the idle up until you put a controller on it. I was in that same situation when i first got mine...

Yes it will mess the quad up. You are running the machine to lean. Its just like a quad with a carb, but instead of jets you need a fuel controller. You will do serious damage to your Raptor if you continue running it like that.

any way to work around it?
i really wont have any money at all until i pay this off.

Unless somebody could hook me up with a commander for dirt cheap, or free  :grin_nod: , doesnt need to be a good one, just to get me through.

I would put back my stocky exhaust if I were you. Just my opinion :)

You better wait and save your engine, than running with an exhaust that don't give you more hp ( well for now ) backfires, and run like sh** The only thing that it gives you, is the chance to blow your engine, which is more than 300 bucks...

I dont have the stock exhaust  :(  :'(

I mean this guy before me had it running like this for 2 years i guess, and its still good, im just looking to get through til august, when i can afford a commander.

 :rofl:

Well, can you baffle it a little bit ? like putting another spark arrestor which is a little more restrictive ?   Or just take out the current spark arrestor, put something restrictive in it, then put it back there... I don't know...  ??? Just an idea I give you, sometime my idea are not the greatest... :lol:

Maybe it would do the trick for now, if it does for 2 years... but sooner or later, it will do what it was supposed to...

Well my dad thinks its to loud, and he might make me get the quiet tip for the GYTR, maybe that will help?

But then again i havent really had it running for more that 2 minutes lol.

I read about Stealerships flashing the computer on the Rappy & trying to help lean conditions. I have no idea how much it helps & it was rumored that when the battery drains dead it needs to be reflashed.  Not a good alterative at all.

Maybe you can find a cheap Dobeck type controller in the for sale threads.

Its not going to run right. You dont have enough fuel which can and most likely will cause engine failure. You better just wait to get a fuel control device.

I will go out on a limb and say you will be fine. If you have the airbox lid PUT IT ON. You are on the borderline of being harmful to the motor.

There are 1,000's of people doing just what you are doing, and you dont hear of people blowing up the motor. Plus look at the guy who had it before you, pipe, filter, and no controller..................so far your quad is running.


But you SHOULD get one ASAP!

Ok thanks, that makes me feel better. Now my next question, im not aloud to spend any money on mods for this things until i pay it off (says my dad) , but my tires suck, bad, like real bad, they are almost bald stockers. I could either ask for a fuel commander or tires for my birthday (august 14). What do you think?

If i ask for the fuel commander he'll probably still let me get tires cause he understands that they are something needed and not really a mod lol..

exactly the last sentence, ask for a PCIII and then he should understand about the tires. you could steal em off your 350 like I did :clap:

:lol: yep

Ill probably get razr 2's.
But i just read on the "other fourm" that i can just bring it to the dealer and they can just make it less lean w/o me having to buy a commander somehow. They cant do it for big mods, but all i have is a pipe, so i should be good?

I have no experience with the dealer flashing your ECU?
I read about it also & someone had said that if your battery goes dead then it needs to be flashed again.  I would treat that as an extremely short fix until getting a PCIII.  Check with  Jaime @ FuelMoto.com for a PCIII

The running-mods-without-an-aftermarket-fuel-controller-discussion is the great debate when it comes to the Raptor 700. I have an opinion on it but rather than just posting information that could potentially harm someone's quad I decided to contact Yamaha Sport Customer Relations and ask them. Attached is a transcript I typed while I was on the phone:

Me: "Is an aftermarket fuel controller required to prevent a lean air/fuel condition on a Raptor 700 that is stock other than a GYT-R slip on muffler?

Yamaha customer service tech: "Using an aftermarket fuel controller is not recommended."

Q: "Why is it not recommended?"

A: "Yamaha does not recommend using aftermarket parts on Yamaha products."

Q: "OK. Yamaha does not recommend using aftermarket parts. Will adding a GYT-R slip on muffler create a lean air/fuel mixture requiring me to figure out a way to compensate for it using Yamaha parts?

A: "The factory fuel controller will be able to handle it."

Q: "I've read that dealerships can perform some sort of flash reprogramming to the fuel controller that will adjust the lean air/fuel condition created by adding GYT-R mods. Why would that be necessary if the factory fuel controller is able to handle factory modifications?

A: "I've never heard of authorized flash reprogramming of fuel controllers."

So there you go. My take on it: If you stick with GYT-R parts you do not need a different fuel controller. GYT-R (Yamaha) sells all sorts of mods that can change the air/fuel ratios (intake, various air filters, pipes, slip ons, quiet tips, etc.). It does not sell a different fuel controller. There is a reason for that.

Sorry But I call BS on this one. Yamaha reps are trained to say that crap for warranty reasons. I had a problem with my intake boot and they tried to say I was not covered because I had a PCIII. I asked them many of the same questions you did. When they told me the ECU could handle the changes.....I asked them how does it "handle" the changes without an O2 sensor. Answer I don't know sir. Also asked them why the sell aftermarket parts that would require me to buy an EFI or damage my quad. Answer I don't know sir. Finally asked them how they came to the conclusion that my PCIII damaged my intake boot? Answer......thats right I don't know sir. After that a manger got on the phone admitted you should have an EFI with any MODs.... GYTR or other and said Yamaha would honor the warranty. I don't think they want to get in the EFI game because than they would have to honor alot more warranty claims.

That was not directed at you rather Yamaha and their BS answers. I would be willing to bet any amount of money that if you dyno'd a raptor with Gytr exhaust, and intake it would run lean. I have a dyno tune and the fuel cells were raised considerably over stock settings. Think about it 1) Why does the bike run like crap and pop? 2) Why would you need and after marker controller for other brands and not GYTR? 3) Don't believe everything Yamaha tells you. They are looking out for THEIR best interest not yours. I just don't want this kid to burn up his quad when a $100 used Dobeck would keep his bike safe and increase power.

I have a dyno tune and the fuel cells were raised considerably over stock settings. Think about it 1) Why does the bike run like crap and pop? 2) Why would you need and after marker controller for other brands and not GYTR? 3) Don't believe everything Yamaha tells you. They are looking out for THEIR best interest not yours. I just don't want this kid to burn up his quad when a $100 used Dobeck would keep his bike safe and increase power.

the bike is even lean from the factory

1) I don't want anyone to burn up their quad either. But really, wouldn't any damage done to his motor have already occurred if it has been run for two years without an aftermarket fuel controller as he typed, and the aftermarket controller proponents are correct? And it's possible the popping he is hearing has more to do with him having only run the engine for a couple of minutes.

2) If someone has a stock motor and intake, filter etc. but also has a GYTR slip on please do dyno it. We would have more to go by.

3) Give me some credit. I do believe in Yamaha parts and it's customer support teams. But I'm not a stooge falling for the Yamaha line.

Anyway, as I typed before: It's the great debate. Feel free to argue amongst yourselves and form your own opinions.

one thing to remember is  elevation will play a role in air/fuel ratio

Really, then why do so many argue that the rappy will adjust its self for that? (I'm on your side :thumbs:)

The 700R's EFI system with it's air temp & air pressure sensor's can only adjust so much....that's why so many people have no problems with a good tune running fine from sea level to around 7000' After that it simply can not compensate. To expect that would take a more sophisticated system with a mass air flow sensor and an O2 Sensor etc.etc.

I would say up to 12K Randy, I got Plug chops that confirm  :thumbs: 

I've run the same map in North Central WI (Wausau area) @ 1,200 ft as I am in the mountains around Beuno Vista, CO (12K).

There are exceptions to every rule Aaron....I think 12K would be about the absolute limit for the 700R's EFI system.
Is your map at all lean at Sea level or your normal riding alltitude?

I took chops after 2 hours riding in WI on a fresh plug, and it matched my plug I ride with in the mountains.

FYI, I just recieved confirmation that Natural Raptor (matt) is also very happy running the same map as I am.  So Now Shawnz in southern AZ, Natural Raptor in San Antonio, Texas.  and Myself are all running the same map very successfully.

Not to mention, that you helped recreate this map, so I can throw RaptorRandy in Oregon to the list.
