Knock Off Carbs

[Ingram306]

So ive been looking for a little while for a set of 28 pwks ( or something similar for a trial bike)... I had a set lines up for a good price and i let them go because other things came up... Anyway, i was wondering if anyone had any experience with these "Replica" carbs that are from Thailand and china... Thanks in advance for any help -Chris

If your talking about the oko carbs,they are comparable to the keihn pwk

 

From what I have gathered from the guy at carb parts warehouse,the oko housings and other components are made by keihn for the OKO motor company.

 

Kind of like how wiseco made Vitos forged pistons.

 

You could technically call them "private label keihns

I put them on 2 bikes in the past. Both sets worked well. The only thing I did'nt like was the fuel bows only has 2 screws holding them on.

I've had the Oko's on a Banshee and a Blaster--they were new, relatively cheap, worked great, and CPW sent them with a couple of jetting choices. I would definitely consider them.

i bought mine new from cpw, and i had a weird problem with them and no matter what i did, i couldnt get them to work.

i ended up swapping back to the stock carbs. one day ill have another shot at them.

 

the weird problem was a break down, at WOT, in a high gear at 4100-5100 rpm. if i went 1st though to 6th it was fine, but if i changed up into 6th or 5th on a slow rolling start, once it got to 4100 it would break down untill 5100 then rev clean.

Maybe a tweaked or dinked needle? Did you try a replacement set of needles? Correct me if I'm wrong, but at that RPM range, it's still on the needle... and it seems that it corrects itself on top, where it relies sole on the main jets...

I ran them for a couple years lil while ago. Never had a problem with them at all. Cheap to buy, simple to work on and they work well.

No need to take the carbs out to change the main, pilot or needle what so ever which is kinda nice.

I think i did a write up a while back about them if you search.

For the money you cant go wrong.

the needles where straight but where a weird tapper N80F's, but if i played with needle hights (as it was WOT the needle was out of the jet) it didnt change if i had the needle on the first clip or the last. If it where the needle, changing the hights should have done something at WOT.

 

if i wasnt at WOT and say 1/2 or 3/4 throttle then yes it could be needles.
