35 PWK... Idle Advice?

[BansheeGuy_IV]

Wes,

 

I'm at Sea Level. Temp in the 60's. I've got a Passion 12 port, +4mm, V-Force reeds, 17cc domes (VP C12), Dyna Ignition Custom curve +5 degrees, Rocket pipes (Yeah I know I need Shearer now)...

 

I've got the 35mm Airstrykers... 150 main, 45 pilots... And I just tried the DEK needles with similar results... Not much of an idle... Seems a bit better than the EGK though.

 

It's loading up down low... Alot of smoke... Very "blubbery" until about 1/8 throttle. I think I can't get an idle because it's just too rich.

 

What needles are you running? I think I am going to drop in some CEL needles next and then I may have to lean down the pilots.

 

I've found that running C12 with the Amsoil 50:1... I tend to require leaner jetting than alot of folks.

 

Thanks guys,

 

BG

60 pilot , dek 5th clip, 140 mains need to bump them up about 1 size. at 900 ft.

Hey guys,

 

I dropped in some DGN needles. Yes, I probably have more needles in my garage than most shops have in their supply. ;-p

 

Anyway, With DGN needles, the badboy idles like a champ, with the idle screws. It's still just a hair funky though. It wants to idle a little on the high side to keep from stalling. Not bad, just a little high. I've got 45 pilots in there. I might have to go up on the pilots a little to make her happy.

 

Funny, In the last post I was saying that I usually require leaner jetting than most folks and I attribute it to the amsoil, VP C12, and just my general location in the world...

 

This seems to be the case once again... Like Wes... He's running DEK needles and 60 pilots and he has no idle problems. My shee won't idle, at all, even with DEK and 45 pilots. I've not heard anyone running DGN needles.

 

I've got some more tweaking to do. I don't know that I'll stick with the DGN after I give it a maiden test ride. I may try the CEL and CGL needles I have.

 

 

So guys... Let me bounce this idea around... The DGN needles... They have a pretty big diameter 2.725 compared to 2.695 for the "K". It mainly should affect off idle through to about 1/4 throttle right? After 1/4 the DGN should be pretty similar to the DGK correct?

 

So if I try the CGL needles... I'm mostly affecting the upper RPM range... Leaner taper... But the diameter is going to be richer than DGN... So I will be going backwards in the idle department which is where I needed them leaned out. THe upper RPM seems good with D or even E series needles.

 

So Hmmm... Alot to ponder. ;-)

dgn you are leaning out the low end.

 

im running pods also dont know if that matters with your setup.

 

jim motors like fuel in the mid and low end.

 

im kinda confused on why your bike wont idle, and to get it to idle you lean it out. when im pourign fuel into it.

 

 

if you can find a dyno with a sniffer around you shoudl put it on it and see how the o2 readings come out on it.

a couple of the guys told you to run cgl or cel. those are the ones youll want to run. with about a 45 pilot

[BansheeGuy_IV]

Hmmm...

 

I have an A/F meter. When I get things dialed in I'll give it a whirl.

 

I am running K&N pods with 6 inches of PVC pipes.

 

What fuel and premix ratio are you running Wes?

 

With the C12 108 octane and the 50:1 Amsoil... That's where I think I'm having to lean it out. I've always had to run that particular setup much leaner than most people.

 

When I went to the DGN needles... Not only does it idle... But it now has instant throttle response off idle... Where as before.... It would fall flat on it's face.

100 LL 927 40:1 is what ration im running

 

maybe your bike likes that jetting. do what makes it run the best

[BansheeGuy_IV]

Hmmm..

 

So I tried some CEL and CGL needles today. No good. The bottom end is too rich. Very difficult to idle... Very smokey... Loading up...

 

DGN needles are it. Really freakin' wierd... Takes an "N" diameter to dial in my off idle throttle. I'd love to know if anyone else is running C12 and Amsoil at 50:1.

It's been raining here for 8 days straight, so I still haven't test rode it. The throttle respnose felt awesome with the DGN needles. I've got to fine tune the pilots though... I think I am actually going to go leaner than 45 pilots... Gonna try 40's tonight with the DGN needles... I just hope the DGN needles agree with the mid and upper RPM range when I go to actually ride it under load.
