Srarted 1994 KX 250 Build.  Can't see a dedicated area to post Pic's and build progress.  First retro build,  members imput suggestions along the way would assist. 

Do members currently post pics and progress of bike Builds?  Is this something of interest to post the progress ect?  I have seen some great bike builds on vital mx.

Probably one of the roughest 94 KX250's
Rust.. on top of Rust.  

Truly amazed how a FMF Fatty Nickel Pipe can look like this!  

It just got worse on closer inspection.  Will try and post.. Attach pic's

i thought mine was bad. yours takes the cake. thanks for working with that one.
 i just paid 900 for 1994 kx 250, needs total rebuild its entire clutch was just laying in it. as soon as i arrived the seller ran the bike down and back. i seen it was salvage and refused to start it. so he ran it with just the cover holding the clutch in the engine. crazy.
 great utube video of this bike winning pro. should be great bike.
 i raced amature in 90s. so im trying to make this bike better than it ever was and run it till im gone. i hope i get  info help. i walked away and forgot what little i new.
 so im looking for help and advise on where to turn for info and parts for this project.same as you.

Like you I brought a 1997 kx250 that had a blown crank, Broken rod in forks, rust, exhaust held on with number 8 wire....... basicly the guy sold it to me and said it used to go hunnits as g. So while recovering from nearly losing my foot 2 years ago I completely rebuilt every single part of this bike over 8 months and now I ride / race it 3x a week. I know this bike inside out and heres what I found.

Cylinder powervalves - getting hard to find / obsolete parts the toothed gears wear out. but there is a person on ebay who can make them.
Kickstart shaft and parts - Can be hard to find as parts are obsolete
indent spring on the main selector fork is weak and needs to have a stronger spring fitted for better shifting between gears.
linkage and shock bearings. shock bearings don't last long so keep a stock pile.
get a good set of stainless spokes and relace those wheels I would invest in a good set of excel rims also.
The older kxs powerband can be a bit like a lightswitch so even for motocross I would recommend a flywheel weight.

Yes it will cost money. Yes it will take time. But when you come out on the other side you will have a really competitive bike that always sticks out at race day ( The old kx sounds amazing)
