My uncle has a 300EX that's like 8 years old and it keeps seizing up on him. So, he got sick of it and gave it to us for practically free. My dad then bought a 2001 motor on ebay for a 300ex with no carb and no starter. My question is: Will this be easy to swap out? We are planning on using the old starter and buying a new carb. What do you guys think??

 

Like 8 years old would be a 99. The 300ex didn't get any major changes from 94 till 05. Any and all parts should swap. The hardest part will be lifting the engine out of the frame.
