I have a complete 250x and 350x engines. both are ready to bolt into the X frame... let me know if you need anything. i have a 38mm carb off a 400ex that bolts onto either quad too. tons of other parts. I have the silver set of maiers. just let me know
 
I would take some info on the motors also.

Sorry for the hijack...
I have an 86 350x motor and and 87 250x motor both bolt into 250x frame

86 350x:
10.25-1 wiseco piston
Was a motor out of a 1986 sacrificed ATC during 1987 crackdown
sat for 19 years under a bench W/O spark plug
bored .020" over and replaced piston.. I have stock piston... it's absolutely mint. so scoring and no carbon buildup... as a testament to it's sitting before i got it and ran only once or twice.
Swapped into 250x frame, cut the rear motor mount to fit... (only modification needed)
Intake is enlarged to fit larger intake for 400ex carb (38mm)
I did use the motor for 1.5 years Then bought a 250r
so naturally, i rode the faster quad :)

I have a modified oil cooler in ok shape (no leaks)
a hand built headpipe for 250x frame
FMF silencer that fits headpipe
wiring harness modified for 350x motor... in ok shape
spacers for 250x Install


87 250x motor:
possibly needs a stator and one long valve cover bolt that broke when fixing a valve cover gasket leak.
never been rebuilt
only stopped using it due to electrical issues.
new stator should fix it.
will run without long bolt.



I also have a complete frame modified to fit 450r shocks/400ex a-arms without those stupid relocation brackets

Mint silver shaved maier Fenders With good seat
lonestar axle
lonestar carrier
300ex/400ex hubs
400ex a-arms
16.25" eye-to-eye z-400 shocks( 1/4" longer than 400ex otherwise identical)
mint stock swingarm
+1.5 steering stem (modified stock) needs to be finished.
all the spindle/front brake parts (300ex)
