Thinking about updating the old Keihin(badly worn slide and internals) Carb on the 1984 CR500 , what would an appropriate choice ?I notice that maybe a more updated Mikuni or maybe a flat slide might be the go , any suggestions on what works with this model. Any help appreciated.

Heaps of discussion on this topic on CR500riders.com forum.  Takes a bit of digging.  They all seem to recomend the PWK Carb.  A few of them have them off a KX500 

Lots of jetting info as well.  The place to go if you need info on a CR500 of any description 

The notes I took say :
PWK 38 or 39.5
Main 175
Pilot 48
Needle 1368 for 38, 1370 for 39.5
Clip 3
Cutaway 6
Idle 2

The KX 500 uses an odd size (39.5mm and makes a vast difference by all accounts)

Here's a new one

I'd love to hear back what you decided on and how it all went.

thanks for all your helpful responses, I am settling on the PWK 39.5MM , I have some slight porting and compression issues to deal with, I will update how things are progressing. cheers.
