Calling The Graydon intake guys

[endofitall9]

alright. I built an aluminum airbox for the graydon 2 into 1 intake. it has a 35mm pwk and right now I'm running at a 148 main and a 35 pilot, needle is de k and I'm using the middle clip, for some reason it just doesnt feel right to me also the airscrew is 2 turns out and I'm running 40:1 klotz. at first I had a low end stutter and I got rid of that now it pulls nice but once in 5th and 6th it just acts like my pipes sign off.. Never had this prob before keep in mind that the reason for all this is the fact that I just bolted on the airbox.. any suggestion all the mods are in the sig. but I am not running the v3's right now I'm running boyesen carbon reeds. thanks guys

Your lean, I have two bikes with the graydon setup, hope this gets you close. 40 pilot, clip at the top of needle, 175 main, 1.5-2 out on air screw, idle srew cranked almost all the way in. I was running the boysenns, I used a 180 main , with the V3's I dropped one main to a 175. Also, trya 50:1 oil, I run Amsoil interceptor.

thanks for the reply bud..but if i ran that jetting in my bike I'd do good to get out of the driveway it would be so rich.. I ran my graydon with a K&N pod for over a year with no problems at all and it was jetted at 162 main 35 pilot niddle in middle clip and with klotz 40:1 .. 50:1 scares me I'm not fond of changing my topened all the time.....I've for the most part gotten rid of the problem down low now it just has problems wiinding itself out in 6th gear any help guys?

day 3 guys and still tuning..ran this damn scenario through my head 100 times and still can't get it figured out..I'm still at a 148 main with 35 pilot airscrew 1.25 turns out...the damn thing is flat in 5 and 6th not even close to the band! I've searched and searched.. could it be float level? I'm going to lower the float to see if I can get more fuel in the bowl..I'm just out of ideas and nobody seems to know anything thing...this thing ran great with the pod on, it was jetted 162 main 35 pilot airscrew 1.25 turns out, pulled great all over now its just a nightmare....c'mon guys.

how about getting two real carburators and fucking all this two into one bullshit??

[endofitall9]

how about this punk ass bitch! How about you come to wayne county west virginia and let me skull fuck you!... piece of shit... 6 posts and your already acting like this that shit is going to fly my friend now get the Fuck off the HQ...

heres what the plugs look like after about 10 min and a wot pass.. its still hesitant in like 1st but my god midrange 2nd through 4th and a little of 5th pull like crazy now i just need to get 6th pulling like it should it just takes a long time to wind out...

The only thing you changed was putting the airbox on it? You had the same jetting and carb and everything? If so I would say that you are a little fat because you are restricting the airflow a little. I am no pro at this, but that would be my guess.

[Snopczynski]

I run a stock motor with bolt ons and dynoport 2 into 1 pipe. I have a 185 main jet in it, so I think your considerably lean on the top.

[Duner440]

I think the elevation is quite a bit different for you guys though. He is at 700 ft. and you are in Washington which I would assume is a lot higher. I dont know though.

[endofitall9]

here let me explain this real good so noone gets confused..This is for a single carb! not a 2 into 1 pipe. Before I had a k&n pod on and the jetting was 162 main 35 pilot airscrew 2 turns out. usining middle clip on needle.. I built an airbox and bolted it on. I knew it would make it fat so is atrted out keeping the 162 main and tried adjusting the needle. Now I went down to a 148 main, 35 pilot needle in middle clip. Before the airbox it pulled fantastic. now with the airbox I can't get it dialed in..when you first start it it sound and revs crisp but as soon as you take off it just acts funny. I know it could be nothing else I bolted my stock duals back on today to see if maybe it was something else and it screams. so now I'm back with the 2 into 1 trying to dial it in and have no idea.. the plugs look good but the bike tells me something else by the way it runs. I would love to get this thing running like ti should with the 2 into 1 because before it was a beast with it on!

 

thanks

I had a way bigger main then you when I ran my 2-1 also. I had 2-1 with 35pwk, PT Mids, 21cc domes, stock airbox - no lid with a k&n filter and I was running a 175 main. That seems wierd, sorry but no help here. If you went from a 162 to a 148 and no help, I would say that's not the right direction. Your filter wasn't clogged or something silly like that before was it?? Is your airbox letting enough air in??

I think the elevation is quite a bit different for you guys though. He is at 700 ft. and you are in Washington which I would assume is a lot higher. I dont know though.

 

Elevation at my house is 550 ft, I ride at the oregon dunes which is sea level. I dont change jetting when I rid in eastern washington which is about 650 ft elevation. Besides, the lower the levation, the richer you would need to be on jetting.

 

I have a single pwk 35 on a trinity intake with a dynoport 2 into 1 pipe. My cousin and my uncle run a pwk 35 on a 2 into 1 intake with twin pro circuit pipes, they run a 1 size bigger main jet than I do. I understand fully what your question is, and your main jet is lean.

 

Adjust main jet first, then needle, then pilot jet. I have a dek needle in the leanest position, 48 pilot, air screw 2 turns out and 185 main jet in my bike on 1 pwk 35mm carb with a 2 into 1 trinity intake. There is a possibility the new airbox is doing something weird with carb velocity. Almost no one runs a airbox on a 2 into 1 intake because they just dont make em. I would try the bigger main jet. Go to like a 180 at least and see what happens. If the bike is lean it will be unresponsive and just seem to fall on its face. If its rich, it will burble.

I stand corrected. I wasnt sure what the elevation was in your area. :thumbsup:

ok I understand how you say I'm lean, but it just doesnt' seem right. I left the carb the way it was when I bolted on the airbox and it was so rich it done good for me to take off.. Now after all the headache I drilled 6, 3/4 inch holes in the box 4 in the bottom and 2 in the back. it does seem lean on top now, 6th gear breaks up bad and it is sometimes hesitant when hitting the band.. I know the bottom is fat as shit it loads up just sitting there and start puffin smoke bad....I guess when I get time I'll jump up to like 1 152 or 155 main as the 162 is just too rich it will barely even take off.. it has baffled the shit out of me I don't know what to do.. it seems like bottom is rich, mid is really good and way up top it doesnt run worth a crap..
