i have been thinking about doing this conversion for a while but i cant get the motor for a cheap price and i dont want to pay for a head pipe that is $400+. but i would like to see step by step pictures because if i ever did get the motor i would do it for sure.

[Honda250XRacer]

yea...but you can make and customize your own header if you know how to do that kind of thing ..well i really hope someone has some pictures..

I have done two of these here is all the info I cut and paste from prior emails to others about the same conversion so it may see a little choppy but it is all there! the major mods where
1. rear top mount on engine needed to have aprox a 1inch Alum cut out very basic with a hack saw all other motor mounts bolt right in
2. you need an exhaust I made my first one (pain in the ***) I bought the second one from powerall perfomance they still sell the pipe for this conversion. but today maybe you could use a 400ex headpipe
3. cutting the oil lines to the oil cooler and flaring them and re locating oil cooler to front also other mods that need to be done that I did not mention. The banjo bolt for the oil line going to the head on the right hand side of 350x motor needs to be filed down take about a 1/8 off or it will touch the ex frame on a jump also I had to cut the tube on both bikes from carb to airbox and connect them I installed a piece of pipe with 2 hose clamps between them because the tube will be to short if not, you should look up posts by speedbump he just finished one and posted some pics of work, basiclly you wil need a 350x motor and harness, you will have to make your own oil lines, to relocate oil cooler, buy a pipe from powerall made for this application unless you are a talented fabricator, the head pipe is much different,and hard to fab although speedbump made his own,at the rear of the 350x motor the top mount on the engine itself needs aprox. 1 1/4 in cut off the trick would be to place both motors on the ground next to each other to see what I mean. The oil line where it meets the cylinder head needs to be ground down a little bit ,off a jump the frame will flex and touch if this is not filed about a 1/8 off the face of the banjo bolt, the rear sprocket on the axle will have to be spaced over about 1/8 to 1/4 for proper chain alignment I used washer between hub and sprocket simple fix
