I have been through most of the threads in the hybrid forums and did a search. I still can't find a lot of info on putting a TRX450R engine into a 400EX frame. I already have my EX built pretty well and haven't been able to find a great deal on 450R close to me. A freind is parting out his R and I can get the engine and related parts for a great price. I just need to know what would have to be changed to make it work. Any pictures of the swap done will help out a lot. I need more power, otherwise I am happy with my EX. Thanks for any help.
