I bound the 52/200 and blue needle on the top clip is killer

... slide they're a little hard to find not every place carries them for the pwk I think I got mine at carparts.com and once you put in the 6.5 slide you're going to have to go back to a more normal sized pilot jet around a 50-52 Then start with a CGK needle and then a CGL needle if its still rich. If you ...

... the pilot and main jet is a balancing act it all fell into place. going bigger on the main jet to LEAN the mixture was just bizarre but sure enough it worked perfectly.

I run a necj needle 52 pilot 205 main and it's incredible tbh.

looking forward to trying one on the 500 in the next few weeks.

Just wondering if anybody has a pwk on their 84, lookin for a jetting starting point pilot,needle,main. Thanks

For the last seven years the STIC has been ...

Standard needle on a pwk39 is a cej ive been told. Circlip is top position leanest on this needle im using. I want to go one needle leaner in the low to mid section. Not sure what numbers/letters etc that is but i have read that a dgk needle with a smilar slow jet size works well in Austraila. I can ...

I think I'd be focusing on the needle rather than the pilot or main. 160 main seems way too lean.

Interesting, in the 2015 300 xcw has 36 mm Keihin carb 0.114 emulsion tube has 50 pilot Suzuki NECJ needle and 190 main. Tad rich down low.
I bet with your Pulse Injector it's an unbeatable combination.

The science is kind of like a vortex tube technology however what appear to be venturi's of varying sizes are drilled into the emulsion tube/needle jet at 60 degree? angles. Somehow (George is 76 yrs) is able to exhaust the hot air in the fuel bowl and use it to break down the fuel/air into that vapor ...

Hello there, do any of you guys have a DGL or even better a r1470r needle?

I'm a 1650 feet above sea level and say 15-20 degrees C, if ...

Does anyone know where I can get a replacement float needle seat for the PJ27N A carb on my 95 CR 500? I ordered the All Balls kit that said it included one, but it turns out it just includes the float needle and not the actual seat that it goes into. I'm not having extreme difficulty finding one ...

... around sea level in ocotillo wells and glamis then upwards of 2,500 in Barstow and Johnson valley. It had a 55 slow jet and a 172 main stock 1368 needle on the 4th clip, I changed to a 60 slow and a 180 main and dropped the needle to the third so I could easily richen or lean the mid. I just picked ...

What is your riding altitude, jetting and needle size?

... of you guys as to how to proceed. I think the basket is pretty shot.
With an 85 CR500R Engine , could I possibly upgrade to the 86-89 basket and needle bearing so that I can have a new rolling assembly??? If the 85 shaft is BIGGER, couldn't the collar be milled on the inside to fit???? I saw on the ...

After grinding the nut off which holds the valve on the shock shaft all of the rebound components fell out. I have a brass looking needle with an oring, a spring and two other parts which look to be spacers. Can anyone tell me how to reassemble these into the shock shaft. It has been months since I ...
