PWK 28mm pattern carbs on flebay

Post by Sean7r » Thu Jan 19, 2017 9:07 pm

I don't normally post but thought I'd share. They supply them in larger sizes also but I'm sticking to the std size as it's going to be a summer fun bike.
They look very similar but are not handed so the idle screw could be an issue, has anyone tried these?
I'm going to take a punt on them as mine are worn really bad between the slide and body.
I plan to transfer all the jets and needles over (if they fit) and hopefully the choke plungers.

Just looked at them , three have been sold, maybe a triple owner!!!
Why does it say you would have to run premix if using on a two stroke?

Probably because there is no Union for a two stroke feed to the carb, not a problem on the KR1.

There are a few people who have used them on the RD forum and added a feed in for the 2 stroke oil, from what ive read, they seem to work well after some set up.

Cheers.

No worries, I'll be testing them during the week. If anybody requires any more information/measurements let me know.

Koso carb fits the air box rubbers and intake rubbers perfectly, so do the choke fittings, the flexible idle cable is a different thread so I'll have to make an adapter, I've adjusted the air mixer screws to one turn out, and these were stiff to turn, so I removed them first, blowout the hole (and the rest of the carb)and refitted, this seemed to loosen them. I'll updat soon.

Had a play with a thread gauge, the kr carb idle screw is m4 0.7 pitch, new carb is m4 0.5.

Sorted, everything bolted up perfect, I ran a remote fuel tank, gave it full choke, and the kr started on the third kick, I balance up the carbs, gave the throttle a couple of blips on the throttle, and it settled straight back down, I'm impressed, I then built the kr up for a trip round the block, well I've not ridden a kr for about 22 years, but it went ok up to 6000rpm, I'm running in a crank and two rebores and I've got the power valve cables disconnected. I still need to drill a vacuum takeoff for the fuel tap.
