Well crank number two took a crap today while i was riding. so id like to get rid of this ****ty trx450 engine and swap in a crf450 engine in its place. What all do i need to do this? and who has experience doing this and or riding on one. Also will it be alot more reliable than the trx450 engine? If its too much trouble puttin a crf engine in my 450 im just gonna sell this thing and try another brand 450. Any and all info would be great i couldnt find much doing a search.
