Hi Guys
My son and I just got home with a new to him 08 700.
the bike seems ok but there has been a few things done.
the guy said it has a "FMF Power Bomb Header and a Big Gun muffler"
but it's not running well and the header gets very hot it also has a really loud muffler on it (to loud to be used around homes) I don't think it has any kind of programer on/done.
also there isn't a air filter cover on the bike.
also the front sproket is toast.
what should I get to/do to the bike? to help it run better?
should I try and find a stock muffler and pipe?
Any thing else I should get done to the bike?

any help would be great

Thanks
Shawn & Kyle

If the bike has a full exhaust then it needs a programmer because its going to be running pretty lean. There are plenty of people who want to get rid of their stock muffler and head pipe if you want to go that route. A 13 or 14 tooth front sprocket can be found almost anywhere as well such as www.rockymountainatv.com

Hi jfdanie2
stock exhaust wouldn't be a bad idea. It may be a cheaper way to go at the time. but it would sort of be a step backwards power wise.
which programmer would do the job? is that something that stays with the bike or just used to reprogram the stock ecm?
any idea if a sprocket from a 400ex would fit?

check out EHS racing. They have programmer's that will work. The programmer has to stay on the bike. Sprockets are cheap. I believe the XX and the 450r use the same sprockets on the front. Not sure about the ex though?

 

[jfdanie2]

There are a couple different styles of programmers as far as how they work. The one that is easiest to use os the dobeck style programmer which is made by many different companies such as EHS racing. The other style is the Dynojet power commander which is a little more expensive but can be tuned a little finer and more precise. It all depends how far you are going to go with the motor, if you're going to go in the motor and make changes later on I would get the power commander, if you're just going to have a pipe the the dobeck is for you.

It needs a programmer to run right with a full pipe. It's probably running really lean. Thats why the pipe is getting really hot. The muffler would probably quiet down a tad if it was repacked. I would suggest getting a new FMF muffler and putting it on there. It will fit right up to the power bomb header. The FMF's are known for being quieter. You can get a new lid for the air box at a honda dealer or online. EHS racing also sales them with outerwear's cover's on them. Check it out at www.ehsracing.com

cv joint

I just noticed that there seems to be some play at the cv joint where it goes in the rearend.
is that normal ?

 

[Red-N-BlackXX]

No that's not normal. Is it the cv or the whole rear carrier?

 

[shawn169]

not sure till I pull the cv
hope it's only the cv cause I'm thinking that would be the chespest of the two

 

[shawn169]

I pulled the spark plug and it's sort of black and sooty so I guess it's not running lean

where would I look to see if there is a programmer installed on the bike?

 

[Red-N-BlackXX]

Under the seat

 

[shawn169]

Well I guess we will try going back to stock for the exhaust.
Any one have a stock header and muffler for a 08 700 ? that they would ship to Nova Scotia?

Thanks
Shawn & Kyle

If u take off the seat and take off the rubber cover that goes over the battery. The programmer would plug in under there.

 

[jfdanie2]

I've got the the stock header and exhaust im not sure how much it will cost to ship.

 

[shawn169]

jfdanie2... how much would you take for the exhaust?

 

[Crash21]

It would be hooked to your fuel injector. It is on top of the throttle body

 

[shawn169]

there isn't any programmer that I can see.
I found an old oem muffler tonite and put that one on. It made great improvements to the way the bike runs. but the header still gets hot. For the cost savings right now we should go back to oem.

we went for a short run tonite and the sprocket started sliping
will have to try and find a new one in the morning

 

[Red-N-BlackXX]

the bike runs very lean and hot when on the stock fuel map. Even more lean and hot when the exhaust and intake are modified.

 

[shawn169]

the plug has that black carbon look to it
so that means it's not lean right?

 

[jfdanie2]

White is lean, black is rich, and a nice paper bag brown is just right. The XX puts off alot of heat, if its black then im sure you are fine.
