So im new to the forums, I just got ahold of a frame that just needs a motor...everything is on it, radiator, all the wiring....the only question that i have is how everyone elses swingarm bolt is ran. i know you have to have bushings made or open up the frame hols a bit but im trying to get some input before i get the motor. any pics of setups would be greatly appreciated as i went though most of the threads and could not find pics of the rear mount. thanks

Use the 400ex swing arm bolt.
You need a bushing made for the yz engine .o95 larger to fit the bolt to the rear of the engine.
The yz rear eng mount is .240 smaller/shorter the the 400ex.
So.....you will need a spacer .240 for the R/H side of the engine.
Get it?

I believe I may still have a spacer and a set of front aluminum mounting horns, if interested.....PM me.
