pj 34s how to tell if there alky carbs

[BANSHEEB0B]

Ok heres what I got 97 banshee ported 4mil stroker 5mill long rod new motor v force 3s .Ibought a set of used pj 34s the pilot was a 50 and the main was a 155 that has been drilled about 4 times as big as it was . I put thes on my bike with a 50 and 155 in it wont idle for crap if you rev it up some times it comes down slow and some times it takes forever screws are 1.5 rouns out and i dont know what needle it has. how can you tell if there alky carbs and if any one knows how to fix this it would be great.

 

 

 

and does any one know the right way to set the flots THANKS

"round here" in the 39mm PWK carbs we use 55 pilots....sometimes a hair bigger.

 

Turn the carb upside down with the bowl off. If the floats are level, or even slightly tilted towards the top of the carb opposite side of the needle/seat, you're good.

 

When you say screws do you mean air screws....or the power jet screws? Does it have power jets?

sounds like just maybe they were switched to alky. if they were there's no switching them back if they drilled out the dump tubes.remove the top and pull the slide assembly out ,turn carb over and remove the bowl and main jet , try to determin if they drilled out the tube. this can be done by using different size drill bits inserted into the tube.

there is only one screw i can findits in the side

the biggest drill bit i can get to go through is a 1/8 but i dont know what is stock

If you can fit a .125 drill bit into the dump tube, it's been drilled out for alky.

i'd say if you got an 1/8 inch bit to go the whole way through the tube that they were probally drilled out. i tried a 34pj i have here and an 1/8 inch is to big to go the whole way through the tube.as i said if keihins are drilled and switched to alky there is no switching them back .the dump tubes are'nt changeable. mikuni's on the other hand can be switched from gas to alky and back again because the dump tubes are changeable.
