It's a Mikuni on mine with a round slide. I've got a choice of two. The one that came off the bike was in a shite state, someone had rammed a wooden peg in where the mixture screw was... I'll strip down the replacement I bought (currently on the bike) and give it a soak in the ultrasonic tank and a blow out with the airline.demographic wrote: ↑Sat Jan 23, 2021 7:02 pm I can't remember what carb the older KXs have, mines got the standard Keihin PWK39 D shaped slide but does yours have a PJ carb?
On about bits that break theres stuff on Youtube about the gusset kit that adresses some of the parts of the frame that break. It's aimed at the 88-2004 frames but still gives a good insight into what issues they have.
Realistically the main issue for mere mortals is the the expansion chamber bracket behind the coil.
Also Sandblaster and KX Guru have done some good Youtube vids.
They all break eventually.
As for cracks...it was properly fucking abused and unmaintained when I got it, but the mount for the spannie looks remarkable sound and so does the rubber mount.
Test ride soon!
