Since I parted ways with my 01 kx125 this past summer, I found another project to do this winter:

day 1.jpg?VersionId=uWSbfhpqBSTRcokiaURAtr1xwb1Mm.

Engine is shot, missing cylinder, head, seat and expansion chamber.

Thinking of doing a splitfire replica.

If anybody has part-outs going on, feel free to PM me.

box

blaster and ultrasonic cleaner today.  Cylinder is pretty scored up so will have to ship it out to Millenium for repair.  Powervalve parts cleaned up great, i broke the shaft with the nut on it so trying to find a replacement for that.  Silencer sticker coming off, nbd, but thinking cerakote on the engine cases since the cylinder didnt clean up as well as everything else.  Did Kawasaki do something special on the cylinder for surface finish?  Its almost like the swingarm paint, where they used black primer on the raw aluminum then silver paint over it....

Got some parts back from the powder coater, waiting on suspension from shop and frame from powder coater.  Millenium technologies has my top end to get sorted.  Put on a few decals and now waiting on parts.  Hoping to have a roller by the end of the month.

Started my 98 build with powdercoat on frame and sub. Still debating on polishing swingarm vs powdercoat (black). I may cerakote the factory hubs. Yours look 👍. The purple is period correct, and looks great with the green!

I found porche silver is the cleanest on the swingarm.  I always like to do the hubs and triples in some kind of accent color, dirty magic was the choice this time but on my past pro circuit replica i did black cherry gloss.

Getting frame from powder tonight.  Waiting on bearings for the rear end and stem.  Top end is here from Millenium technologies.  Time to get the bottom end sorted.  Goal is to get tires/tubes mounted in 2 weeks and have a roller that i can sit on and smile after all the time and resources into it this far.

Picked up forks and shock yesterday; waiting on stem bearings to show up and swingarm bearings (found a deal for bearings and seals from a seller on ebay from Germany).  Adept is dragging their feet on shipping my spokes and nipples to finish up my wheels and get tires/tubes on after that.
