The PJ carb is your meat and potatoes in the 2 stroke world.It has been factory equip on everything from 125-500 on a range of manufacturers.It is a very simple design that utilizes a combination knob for the choke/idle and has an oval slide.They are a little tricky to jet for the novice,but anyone who understands carbs will have no problems dialing one in. The PWk is more refined.it has become the standard in kehin 2 stroke carburation.It is basically the replacement for the PJ.It utilizes a choke knob that is separate from the idle screws.The slide is also different,more of a crescent shape than oval The PWK airstryker is an "improved" version of the standard pwk.Its preferred by racers for its tuneability and wide range of performance.

locogato11283 Posted September 18, 2011 Report Posted September 18, 2011 Airstrykers are junk. They're hard to tune. Go with regular PWK. Quote
RippinBansh11 Posted September 18, 2011 Author Report Posted September 18, 2011 Airstrykers are junk. They're hard to tune. Go with regular PWK. Really? im gonna be racin on ice and doing a lot of tuning too.. some days its -10 and other days its 40 degrees.. What about the PJ's?? Quote
jbooker82 Posted September 18, 2011 Report Posted September 18, 2011 Really? im gonna be racin on ice and doing a lot of tuning too.. some days its -10 and other days its 40 degrees.. What about the PJ's?? I would consider PJ's as old and out dated. I had a set of 34's and ditched them for PWK33's. The only thing they do better that the PWK is that they can be bought cheaper. So if your looking to save some coin and dont mind screwing with them then go for it. There are guys on here who do run PJ's. Quote
252wheelieking Posted September 18, 2011 Report Posted September 18, 2011 I run 34 PJ's & personally think they are a very good carb. I wouldn't switch from a PJ to PWK because the price of the switch isn't worth it. From my experience of tuning PJ & PWK carbs are the same except the choke/idle knob on the PJ is all in one. It's easy: PJ carb Pull choke/idle knob up = choke on Push choke/idle knob down = choke off Turn choke/idle knob by clicks clockwise/right = higher idle Turn choke/idle knob by clicks counter clockwise/left = lower idle Quote
locogato11283 Posted September 18, 2011 Report Posted September 18, 2011 Tuning PJ and PWK is not the same. The PWK are far easier. They're a more up to date carb. If you don't have enough for PWK I'd save until you do. There is no easier carb to tune than the PWK. Quote
Zwiser Posted September 18, 2011 Report Posted September 18, 2011 From my understanding, the air striker has more vents so that you have less of a chance clogging all of the vents with dirt if your racing Quote
hp2000 Posted September 18, 2011 Report Posted September 18, 2011 PWK carb Pj carb My pwk is a 39 the PJ is a 36 that's as close as I had for comparison Quote
locogato11283 Posted September 18, 2011 Report Posted September 18, 2011 From my understanding, the air striker has more vents so that you have less of a chance clogging all of the vents with dirt if your racing That's the problem with them. Those vents affect the jetting. Quote

If you don't have enough for PWK I'd save until you do. There is no easier carb to tune than the PWK. From my understanding of jetting & tuning carbs you use the same concept on both carbs. The only differnce is PJ has choke/idle knob on same knob. PWK has a knob for the choke & screw for the idle. I do understand that the PWK is more modern, but what makes the PWK so much easier?

locogato11283 Posted September 18, 2011 Report Posted September 18, 2011 The jetting circuits are different. The PWK are better hands down. If they weren't you'd see more people running PJs and other carbs. The PWK series are the most popular carb for a reason. I'm not saying PJs are bad carbs. PWK are just better. Quote
RippinBansh11 Posted September 18, 2011 Author Report Posted September 18, 2011 (edited) Thanks for all the input! Looks like 35mm PWK's it is! Not to throw a wrench in this whole deal but what about Mikuni carbs????? lol Edited September 18, 2011 by RippinBansh11 Quote
