If you check out Performance Mods and Mechanical section and look for 350x Motor in a 250x Frame you will see lots of info, if you require more email me at jbach72@yahoo.com I forgot to mention that you will require the wire harness from the 350x. I can email photo's, have Digital camera so just let me know what photo's you will need....

 

if you want power from you 300ex..go for a 330 kit


get more power than a 350x and a 400ex. plus keep reverse
