BansheeGuy_IV Posted October 9, 2005 Report Posted October 9, 2005 Hey guys, I'm setting up some 35mm PWK's. I've never used them before. I'm having a little difficulty with the idle. I can screw the idle screws all the way in, bottom them out, and it still isn't enough to get the slide high enough to idle. I can make it idle by adjusting the tops of the carbs, but that isn't correct. I'm wondering if anyone has any suggestions. I've got 150 mains, EGK needles, 45 pilots. Runs great, just can't get the idle screws to work. Thanks, BG Quote
locogato11283 Posted October 10, 2005 Report Posted October 10, 2005 hmm i run 45 pilot and it works out fine..could be that needle...think im runnin cel needle..not sure if its leaner or richer than urs... Quote
wesw Posted October 10, 2005 Report Posted October 10, 2005 as far as jetting i think you need a 55 pilot or some what larger. also the egk needle is lean in the L1 position. meaning lean down low, the g series are lean, you should try ike a eek, or dek. you might be really lean and your bike doesnt want to idle very well Quote
reded Posted October 10, 2005 Report Posted October 10, 2005 I had to use the cable adjusters on carb caps to get mine to idle. In order to get the cable the right length I had to install the shorter adjusters. You need to synchronize the carbs at the same time tho, otherwise it will never idle properly. Quote
BansheeGuy_IV Posted October 10, 2005 Author Report Posted October 10, 2005 Reded, I am using a Stainless braided cable from Jim at Passion. Really nice cable. Anyway, It's really easy for me to resize the cable. I have universal ends that I solder on. I already had to take 3 inches out of the main cable going to the twist. I would really prefer to have it idle via the idle screws, but I'm not against setting the idle with the cable adjusters. I just don't want to go shortening the cables and adjusting the idles via the cables if in fact it should be idling with the screws. Meaning... If the reason it isn't idling is because my idle circuit is incorrectly jetted then I want to fix it. It doesn't seem to be the case though, because it runs perfect from bottom to top. It isn't loading up. The plugs are a great color. The power comes on smooth throughout the RPM range. But to idle, I have to tweak the throttle about 3/32 of an inch to maintain a nice smooth RPM. This is something I can easily correct with the cable adjusters, but I wanted to rule out the jetting first. Are other folks able to get the 35MM PWK Airstrykers to idle without having to use the cable adjusters? By the way... I appreciate all the advice... Folks chiming in who run the carbs... It makes my job alot easier trying to figure it out. I've spent all my time tuning Mikuni carbs. They are all I used on my setups... 36mm TMX carbs... 34MM TM's... 28MM TM's... They all are very easy to make idle. So this is new territory for me. Thanks, BG Quote
Pest Posted October 10, 2005 Report Posted October 10, 2005 I had to do this with all my PWKs 35s to 40.5s. Take the idle screw completely out and cut the spring in half and reinstall, should give you alot more range of adjustment. Quote
s-540 Posted October 10, 2005 Report Posted October 10, 2005 try turning the idle screw in and looking into the opening to see if the slide moves up. Quote
trex banshee Posted October 10, 2005 Report Posted October 10, 2005 i has the same problem with my 35's, wouldn't idle at all on gas but when i switched to alcohol it idles perfect now plus lots more power! Quote
blueshee03 Posted October 10, 2005 Report Posted October 10, 2005 (edited) i run 35pwk airstrykers and it idles fine with no mods to springs or cables after i got the pilots right.i run 40 pilots ,140 mains and dek needles.i'm at around 3000ft so i'm sure my jetting and such will be different than yours but you could try to go down or up a size or two on your pilots and try it.i had regular pwk's and these airstrykers were a bit different on the jetting than the regular pwk's.

BansheeGuy_IV Posted October 11, 2005 Author Report Posted October 11, 2005 Aww heck... Some of you have the idle issue and some of you don't. Now I don't know what to do. ;-/ BG Quote
RNBRAD Posted October 12, 2005 Report Posted October 12, 2005 Aww heck... Some of you have the idle issue and some of you don't. Now I don't know what to do. ;-/ BG 424970[/snapback] Will it idle with the choke at all or idle better with the choke on? If so go up on your pilot to around a 50 to 55. Switch to a CEL needle also.

FASTOYS Posted October 12, 2005 Report Posted October 12, 2005 We had the same problem with air strykers. They should idle if you change the needle to maybe a CEL or CGL and might have to play with the pilot too. But they will idle. Pm me if you need needles or help. ALso reded , the adjusters i got ya were longer (not shorter) so you could have full throttle! Quote
BansheeGuy_IV Posted October 12, 2005 Author Report Posted October 12, 2005 I was just playing with it... It's definitely rich in the needle. The choke as expected... Makes matters worse... It will idle fine though, if I tweak the throttle a little bit. I suspect leaning everything out should do the trick. Ya'll think I should go up on the pilots when I go down on the needles? I Have CEL, CGL, DGK, DEK, EGK, EGL needles... Got a nice mix of all the series. I have every pilot from 40 to 60. Every main from 140 to 160. BG Quote
wesw Posted October 13, 2005 Report Posted October 13, 2005 most e series are really rich and used for alky setups. i would try the dek or any d series. and play around with your setup. whats your elevation. Quote
