    the TB 28 it a PE28 copy with the right needle in it from the get go and i love it easy to tune and makes geat power. jseeint for stock 155z (for me ) has been 44 pilot 100 main needle in the middle. on a V2 155 it has been 50 pilot 120 main needle in the middle.



    with the pwks if you dont have a good throttle spring they slide can float and letting can be a bit*h

    Re: pe 28 vs pwk 28

    i have both the original PE28 (from daytona japan) and the genuine pwk28 on my Daytonas 150 and both are very good, i've found a better response with the pwk..

    Re: pe 28 vs pwk 28

    I run the PWK28 on my Lifan 150. I use a JJG needle, a 107 main, and 42? pilot.



    The fix for the throttle spring is to replace it with one from a stock KLX110 carb. I did and haven't had any problems with the throttle sticking.



    The TB28 carb has issues. The coating on the slide flakes and causes it to get stuck in the bore.

    Re: pe 28 vs pwk 28

    Can anyone advise on the right jetting for a pwk28 on a YX150? I seem to have a problem on the bottom and it smooths out but still isn't what it should be. I have no idea what's in there now. One of the first things I'll do is replace the spring as recommended but that still leaves the jets???? Anybody????

    I have a PE28 and love it. No change of the needle is needed either...

    Re: pe 28 vs pwk 28

    it depends on elevation for the needle change

    We will have a 155z motor in next week, we will dyno with the pe and pwk 28 and pm you .



    On the klx 178 motors the pwk is what we run.

    Re: pe 28 vs pwk 28

    PE28 will pull more hp but the PWK28 is easier to jet and has the atomizer other than tha they are basically the same... oh and one is a round slide and the other is a d-slide. I've had both and have had better luck with the PE but everyone seems to prefer the PWK

    Re: pe 28 vs pwk 28

    well not to confuse anyone but they didnt have my engine together so i opted to throw down the extra cash for the 184 big bore kit .so now i have the 184 kit with a v2 ,billet clutch pitster decomp kit and a heat wrapped titanium fmf exhaust. so my new question is can the pe 28 handle all this and wat kind of jets should i expect to run ? elevation is around 2200 ft
