My ideas are as follows: Take out the 400cc trx engine, mod up the frame(strengthen with gussets), tac in new motor mounts, fit new motor crf450, build the necessary suspension and axle mods... Reason for this thread is to absorb my fellow modders ideas and suggestions for my project. specific details would be much appreciated such as angle and fitting of the new motor into the frame. any ideas in lengthening or widening the quad itself ... etc. PLEASE throw anything you got at this!!!
