Exhaust/JetKit ?

dancrosoft · February 16th, 2009, 11:31 AM

Hello to all!

I just got my AreaP and my JetKit on Friday. I have read through all of the DIY/FAQ and this install seems fairly straight forward. I am not the most technical savvy when it comes to engines but I do most work on my Camaro < (Yes I am another Camaro owner with a 250 hehe) Anyways I was wondering if you guys think this is something that I can attempt to do myself.

Also I have read something about syncing the carbs? Is that something you have to do after jetting?

Thanks for any help/advice you wise people can offer

dancrosoft · February 16th, 2009, 11:39 AM

Also I got a K&N filter I am going to be putting in. I am not sure if that changes things up or not....

....Let the learning beginnnnnnn....

Hi Dan!

I have also got an AreaP exhaust and Jetkit. I have installed the exhaust, it is really easy, just be sure to follow the DYI and torque the nuts/bolts to the specs mentioned in the DIY and all should be fine. the AreaP headers are a very close fit

I have not installed the jetkit as yet (no time due to SWMBO

), but I have had the carbs out and it is not as daunting as it looks. You will be fine as long as you take your time and note what you do (I do this with pictures)

What type of K&N filter is it? Pod, or just a slip in replacement for the existing one?

dancrosoft · February 16th, 2009, 12:16 PM

It is just a slip in replacement. I didnt want to go with the pod yet...

The filter was on sale so i went for it hehe

Viper-Byte · February 16th, 2009, 12:26 PM

It will be a straight swap then, obviously jet settings will need to be different to the stock filter, but that is what the jetkit is for

kkim · February 16th, 2009, 01:15 PM

what brand jet kit?

dancrosoft · February 16th, 2009, 02:39 PM

Its a dynojet

I am about to go attempt to do it now... Just got the exhaust on

it sounds goooooooodddd

kkim · February 16th, 2009, 03:55 PM

have a look at the jetting database to see what others using DJ kits have used. http://www.ninjette.org/forums/showthread.php?t=10208

be sure to add your info once you get yours in and tested.

Always nice to sync the carbs, no real big deal if you cant get to it right now.

dancrosoft · February 16th, 2009, 06:26 PM

OMG it was a nightmare. I am still not done... lol. I worked for as long as I could then got cold as ballz. Decided to hang it up and go again tomorrow. Here is what I got done and I have a few questions if anyone can help....

I got the exhaust put on. That was fairly simple....

I got the bike apart as in the DIY and got the carb out. I did it a little differently but It worked all the same. I did get the new needles in... With the C clamp on the 3rd notch and the 2 washers on top. < that part was a bitch. (Question 1 will be about this...) I did not get the jets put in as I need to find a better screw driver, as mine will not fit in the damn hole...

(Please excuse my lack of terminology)
Ok question 1: On the top side of the carbs. There is a diaphragm that you take out to put the needle in. It has 2 holes. A big one (needle) and a little one (dunno wtf its for). I did not look and see which way these go back in. lol do the little holes go up or down or will it only fit one way?

2. Also the DynoJet manual says to use 098... Is that correct?

Again apologies for my noobish lack or terminology.. I is a computer guy and am doing this for the first time...

(At any rate I covered her up and hung it up for the night.) Thanks for all the help

kkim · February 16th, 2009, 06:33 PM

1. the slides can only go in one way. I was afraid I had installed mine backward myself when I first did mine and I had to ask the very same question.

2. yes, use the DJ 98 jet. DJ uses their own numbering system and it is actually richer than the stock Keihin 98. With the K&N and pulling the snorkel, you'll be fine as they will allow you more air to compensate for the now larger DJ 98 main jet.

3. yes, it is a PITA to rejet the carbs, but soooo worth it.
some pictures I took of mine when I did it, if you are interested. http://picasaweb.google.com/kkim993/AirboxAndRejet#

dancrosoft · February 16th, 2009, 06:40 PM

AWESOME MAN!!! these pics help more than anything. THANKS!!!!!

islanderman7 · February 16th, 2009, 09:30 PM

Oh the memories...

good luck man. You'll get there eventually. Its worth it in the end.

kkim · February 16th, 2009, 09:30 PM

dancrosoft · February 16th, 2009, 09:31 PM

Hahaha. I am just hoping I dont break anything. Figuring out where those hoses go is gonna be insane....

dancrosoft · February 16th, 2009, 09:33 PM

Speaking of putting stuff back together... Does this void he warranty? lol

kkim · February 16th, 2009, 09:34 PM

it's not that bad.. just figure out one hose at a time. that's the reason I take a lot of pictures before I tear stuff apart. also, a factory service manual is mandatory.

If your owner's manual is your guide, the service manual is your bible.

only if the work you did causes problems in the area that failed. The bike won't pass emissions controls if your state has them, though.

dancrosoft · February 16th, 2009, 09:37 PM

hmmm that is not good... i am not sure if they require it on bikes here. i know they do on new cars...

dancrosoft · February 16th, 2009, 09:40 PM

Nope just checked... not on bikes and they dont require it on cars in my county either.

kkim · February 16th, 2009, 09:42 PM

whew!

islanderman7 · February 16th, 2009, 09:42 PM

Yeah a service manual is handy. It is nice to see an exploded view of what your working on when you get stuck. So hopefully you have one.

dancrosoft · February 16th, 2009, 09:43 PM

Nope... Just ordered one now... lol will have to either wait on it or wing it...

dancrosoft · February 17th, 2009, 03:56 PM

This NOOB did not break his bike!!! She is running and sounding good!!!

I just have 1 question.. I am not sure if this is normal or not..... When I crank her up (it is cold here so I have to apply some choke. I wait for it to get warmed up before I start revving. When I revved it up a bit to about 5k i noticed that it took longer for it to come down back to idle..... Is this normal with the kit or do I need to adjust something??

Thank for all your help!!! Could not have done it without the guys on this site!!

kkim · February 17th, 2009, 04:14 PM

Coming back down slower is not normal. Bike should act pretty much the same as before the jetting in this regard.

Is the bike completely warmed up when you are noticing this? Have you test ridden the bike and does it act the same when riding?

dancrosoft · February 17th, 2009, 04:26 PM

Havent rode it yet... Was just testing in the garage. I did not give it enough time to get hot i dont think. I will give it a go and let you know the results.

dancrosoft · February 17th, 2009, 04:31 PM

Have it running rite now behind me. Looks like it idles at between 1000 and 1500....... Has been running for about 10 mins and is still doing the slow thing..

kkim · February 17th, 2009, 04:37 PM

then adjust the idle with the idle adjustment knob.

I set mine to 1500 cause it's just easier to read it to get it right on.

edit- you sure you have all the hoses hooked back up correctly?

dancrosoft · February 17th, 2009, 04:41 PM

Ahh I see... got the idle back to normal.. I am going to make a video of what its doing.... So you guys will see what I am talking about. Gonna do that now then hang it up for tonite. Atleast its running

dancrosoft · February 17th, 2009, 04:51 PM

Seems to be ok when I let it warm up for quite a while.... Havent drove it yet... Will take it for a spin tomorrow.

OldGuy · February 17th, 2009, 05:52 PM

Dan/Kelly,

Sticks in my mind there is a thread with this type of issue and the long fall off to idle was a sign of being to rich (?)

dancrosoft · February 17th, 2009, 05:55 PM

once again apologies for my noobishness.... How do I correct it?

OldGuy · February 17th, 2009, 06:07 PM

I think I had it bass aackwards - you're lean not reach.

dancrosoft · February 17th, 2009, 06:37 PM

Thanks!! Ima go get me one of them fancy screw drivers tomorrow and play with the idle screws

hopefully that will do it

kkim · February 17th, 2009, 07:27 PM

Dan,

Ride it and then tell us what it's doing/not doing at that point.

dancrosoft · February 17th, 2009, 08:14 PM

Will do. I am going to go get one of those screw drivers and adjust the idle mixture screws. That seems like the problem. It runs fine other than the idle issue and the slow to come down to idle.

kkim · February 17th, 2009, 08:30 PM

where are your mixture screws set at now?

dancrosoft · February 18th, 2009, 01:30 PM

Anyone know what the perfect size flat head bit is to adjust the idle screws? I think I read somewhere It was a 5...
